DANIELS TM ELECTRONICS LTD vi CI-PM-3 Paging Modulator Instruction Manual 1 1.1 GENERAL Introduction The CI-PM-3 Paging Modulator module is an optional plug-in component of the MT-3 Radio Repeater System. This module provides digital and/or analog paging capability for Daniels MT-3 transmitters in all supported frequency bands. The CI-PM-3 is designed for low power consumption, typically drawing less than 250 mA in steady state. In its standard configuration, the CI-PM-3 uses an on-board frequency reference source consisting of a 10 MHz OCXO with a standard stability of 0.03 PPM. For high stability applications (such as Simulcast), the CI-PM-3 Paging Modulator may be configured to use an external high stability reference source (i.e. rubidium, GPS or WWV) with a standard stability greater than or equal to 0.002 PPM, to discipline the on-board phase-locked loop OCXO oscillator. To ensure that paging signals are the same relative to each transmitter, the CI-PM-3 also incorporates a limited delay compensation for the different link propagation paths between transmitters. The CI-PM-3 Paging Modulator supports both analog and digital paging formats, and can transmit POCSAG and other 2-level modulation schemes at data transfer rates of 512, 1200, and 2400 Baud. It can also be configured for use as a data repeater, whereby 2-level paging data is recovered, re-shaped and then re-transmitted to an additional repeater/paging transmitter. The CI-PM-3 supports 4-level modulation formats in non-repeater mode (i.e. in a base station paging transmitter application only) at data transfer rates up to 1600 BPS. Each of the four modulation deviation levels can be independently set, making the CI-PM-3 suitable for use in such pager signaling schemes as Motorola’s FLEX™ Paging Protocol. Setup conditions are established via front panel switch settings, while internal jumper settings and setup adjustments are easily accessible using the EC-96, 96 Pin Extender Card. The CI-PM-3 Paging Modulator includes the following standard features: low power analog and CMOS control circuitry. extended operating temperature range; jumper selectable Repeater/paging transmitter configuration; on-board +/-0.03 PPM 10 MHz OCXO; front panel selection of PLL OCXO using external high stability frequency reference; jumper and line selectable analog / digital paging configuration; connection for optional CTCSS encoder / decoder; balanced 600 Ω / single-ended microphone input; selectable digital delay for Simulcast operation DANIELS TM ELECTRONICS LTD CI-PM-3 Paging Modulator Instruction Manual 1-1 1.2 Construction The CI-PM-3 Paging Modulator is packaged in a compact Eurostandard shell module housing of nickel/steel with an anodized aluminum front panel. Corrosion resistant fasteners are used throughout the assembly. 1.3 Printed Circuit Board Numbering Convention To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a printed circuit board (PCB) numbering convention in which the last two digits of the Circuit Board number represent the Circuit Board version. For example: • PCB number 50002-02 indicates Circuit Board version 2.0. • PCB number 43-912010 indicates Circuit Board version 1.0; All PCB's manufactured by Daniels Electronics are identified by one of the above conventions. 1.4 1.4.1 Specifications General Specifications Model Number: CI-PM-3 Type: MT-3 Series Paging Modulator Compatibility: MT-3 Series Radio Systems Modulation: 16K0F3E (FM Analog), and 14K7F1D (FM Data Transmission) Audio Input: Balanced 600 Ω(tone or voice) Digital Input: Bipolar: Reference Input: 10 MHz, 0.5 to 2.5 V rms, 50 Ω Front Panel SMA Reference Output: 10 MHz (Modulated), 2.5 V rms, 50 Ω Front Panel SMA DANIELS RS-232 compatible TM ELECTRONICS LTD 1-2 CI-PM-3 Paging Modulator Instruction Manual Frequency Stability: Standard: Optional: ±0.03ppm from -40°C to +60°C External High Stability ±0.002ppm from -40°C to +60°C (requires WWV or GPS reference source).

Table 4-4 contains a complete list of CI-PM-3 default jumper settings. The CI-PM-3 can also be configured for 4-level signal (base transmitter only) paging, remote paging, link repeater or higher stability operation. Each of these configurations is covered separately in the following sections. 3.2 Repair Notes Removal and replacement of surface mount components should be performed only in specifically designed surface mount rework and repair stations complete with electrostatic discharge (ESD) protection. To help prevent damage to the circuit board pads when removing Surface Mount Solder Jumpers, it is recommended that solder braid be used in place of manual vacuum de-soldering tools. 3.3 Recommended Equipment List Alignment of the CI-PM-3 requires the following test and radio equipment, or its equivalent: • Power Supply: • Oscilloscope / Multi-meter: • Current Meter: • Radio Communications Test Set: • Sub-rack: • System Monitor: • Transmitter Module: • Extender Card and Cable: • Alignment Tool: Regulated +13.8 VDC at 2 A Fluke 97 Scopemeter Fluke 75 Multi-meter Marconi Instruments 2955R (W/External Reference) Daniels SR-3 Series 19” Sub-rack Daniels SM-3 Series System Monitor Daniels Enhanced Performance VT-3 / UT-3 Series Daniels EC-96K, 96 Pin Extender Card and Cable Johanson 8766 Note: It is highly recommended that the Radio Communications Test Set be frequency locked to an external 10 MHz reference (WWV or GPS), especially if the factory-adjusted frequency settings are to be altered in any way.

Adjust R23 (BP DEV ADJ) for maximum deviation of +/-4.8 kHz. 3.10 PLL Setup CI-PM-3 PLL adjustments are factory set. It is strongly recommended that they not be altered. The following procedure applies only if field adjustment is required: 1. Install Power Enable surface mount jumpers JU37, JU39, JU56 and JU59. 2. Ensure front panel SW1 (FREQ REF) is set to EXT, and shunt jumper JU6-A is removed. 3. Set shunt jumpers JU23-A and JU41-A (or not installed). 4. Connect the 50 Ohm output of a high stability, 10 MHz reference to front panel REF IN SMA connector J3. Ensure the output level of the external reference is between 0.5 to 2.5 V rms. Steps 5 through 7 apply to Daniels VR-3/150 transmitters. 5. Measure and record the voltage at TP13 with the DMM. 6. Measure the voltage at TP12 with the DMM. 7. Adjust PLL CAL potentiometer R101 until the voltage measured at TP12 matches the voltage measured in step (5) above within ± 0.2 Vdc. Note that when the PLL locks in, the voltage at TP12 will also lock in to within ±0.2 Vdc of the voltage at TP13. At this point further adjustment of R101 will not change the value unless it is brought out of lock. DANIELS TM ELECTRONICS LTD 3-4 CI-PM-3 Paging Modulator Instruction Manual Steps 8 and 9 apply to Daniels UHF transmitters. 8. Monitor TP12 with an oscilloscope. 9. Adjust the PLL CAL potentiometer R101 until the voltage measured at TP12 is over 2.7 volts. You should observe a clean DC voltage when the PLL locks in. Any voltage below 2.7 volts results in a badly distorted 10 MHz square wave. 10. Replace shunt jumper JU6-A. 3.11 Data Delay Setup 1. Enable the DATA DELAY option by installing Power Enable surface-mount jumpers JU38 And moving the two DATA DELAY shunt jumpers of JU36 to the DELAY (vertical) position. 2. Set front panel switches SW2 (MODE) to SETUP, SW3 (SET MOD) to 2 LEVEL, and SW4 (SET DEV) to “Continuous Bit Stream” (refer to SW4 DETAIL in Figure 6-1). To calibrate the positive and negative edge delay: 3. Set the oscilloscope for 1.0 V/Div (vertical) and 0.5 µs/Div (horizontal). Select channel 1 as trigger input and set Trigger Slope to positive. 4. Monitor the data signal at TP9 on channel 1 of the oscilloscope. 5. Monitor and record the period of the data delay pulse at TP7 on channel 2 of the oscilloscope. 6. Set Trigger Slope to negative. 7. Continue monitoring the data signal at TP9 on channel 1 of the oscilloscope while monitoring the period of the data delay pulse at TP7 on channel 2. 8. Adjust R95, DELAY SYNC, until the period of the data delay pulse measured at TP7 is identical to that measured in step (5) above. To set the delay resolution (output frequency of Programmable Counter U22): 9. With surface mount jumpers JU31A, JU32A and JU33A installed, monitor the frequency of the signal at TP8. 10. Adjust tuning capacitor C55 for a frequency of 1.0 MHz (+/- 10 Hz) at TP8. DANIELS TM ELECTRONICS LTD CI-PM-3 Paging Modulator Instruction Manual 3-5 3.12 Simulcast Delay Setup A typical Simulcast system is depicted in Figure 5-2. To correctly determine the differing propagation path delays to each transmitter in a Simulcast system and compensate for them, signal delays in both the transmission medium and the equipment must be known. For the purposes of this manual, it is assumed that only Daniels MT-3 radio equipment will be utilized at each paging site, and that each radio subrack will be identically configured with CI-PM-3 Paging Modulator modules. Signal delays from the base transmitter to any paging transmitter are calculated as follows: Where: Delay t(Link) + t(Eqpt) t(Link) t(Eqpt) t(RX) t(PM) t(TX) Propagation delay from Base TX to Paging TX t(RX) + t(PM) + t(TX) Delay through Receiver Delay through Paging Modulator Delay through Transmitter Distance The delay through the equipment at each paging transmitter site, t(Eqpt),will be identical for each link, and can therefore be eliminated from our calculations. As such, the only delay variable(s) of interest will be the distance from the base transmitter to each paging transmitter. Since radio waves propagate at or near the speed of light (3x108 m/sec), the delay calculation becomes: = t(Link) = d (km) × 3.33µsec Delay or = d (mi) × 5.37µsec For the Simulcast system depicted in Figure 5-2, the signal transmitted by PAGING TX #1 will not be delayed, as this is the furthest site from the BASE TX. However, to ensure identical signal processing characteristics at each site, the DATA DELAY circuitry of the CI-PM-3 at PAGING TX #1 will be enabled, but with zero delay selected. PAGING TX #2 will have its paging signal delayed by a value proportional to the difference in distance between PAGING TX #1 and PAGING TX #2 to the BASE TX. The delay for PAGING TX #2 is therefore calculated as: Delay(Link B) DANIELS (d(Link A) (km) - d(Link B) (km)) × 3.33µsec or (d(Link A) (mi) - d(Link B) (mi)) × 5.37µsec TM ELECTRONICS LTD 3-6 CI-PM-3 Paging Modulator Instruction Manual The delay calculations for any paging transmitter site in a multiple-transmitter system, with distances measured from the site of interest back to the BASE TX, becomes: Delay(Site of Interest) (d(Furthest Site) (km) - d(Site of Interest) (km)) × 3.33µsec or (d(Furthest Site) (mi) - d(Site of Interest) (mi)) × 5.37µsec To set the delay value: Once the required delay has been calculated for a particular paging site, refer to Table 4-3 delay settings: a) Locate the DELAY (µsec) value which is closest to the calculated value. b) Set surface mount jumpers JU31, JU32, JU33, and JU35 according Table 4-3 in section 4.3. Data Delay Adjust: To set delay values other than those listed in Table 4-3: 1. Set the oscilloscope for 1.0 V/Div (vertical) and 0.5 µs/Div (horizontal). Select channel 1 as trigger input and set Trigger Slope to positive. 2. Monitor the test data signal at TP9 on channel 1 of the oscilloscope and the output signal at TP5 on channel 2. 3. Adjust the oscilloscope for maximum horizontal display of the distance between the signals’ leading edges. Adjust tuning capacitor C55 until the output signal’s leading edge on channel 2 is delayed from the input signal’s leading edge on channel 1 by the desired delay amount. Example: To set a delay of 44 µsec: i) Set oscilloscope horizontal resolution to 5 µsec/div. ii) Install surface mount jumpers JU31B, JU32A, JU33A and JU35E (refer to Table 4-3). iii) Monitor TP9 on channel 1 of the oscilloscope. Monitor TP5 on channel 2 of the oscilloscope. Adjust C55 for 8.8 horizontal divisions between the signals’ leading edges (8.8✕5 µsec = 44 µsec delay). DANIELS TM ELECTRONICS LTD CI-PM-3 Paging Modulator Instruction Manual 3-7 3.13 Repeater Configuration The CI-PM-3 modules at both the base transmitter and paging/repeater must be configured individually. Individual setup procedures must also be followed for analog/digital paging and for digital-only paging. Note: The CI-PM-3 modules must be set for 2-level signal operation only when configured for use in a paging repeater system. 3.13.1 Base Transmitter Site CI-PM-3 Configuration The setup instructions of sections 3.13.1 through 3.13.3 must be completed prior to commencing setup of the remote paging/repeater site CI-PM-3.

The transmitter operates continuous duty in one of four frequency bands: 406 to 430 MHz, 450 to 470 MHz, 470 to 490 MHz or 490 to 512 MHz and its output power is continuously adjustable from 0.5 T0 2.0 or 2.0 to 8.0 Watts. The transmitter is not to be operated within the 406 to 406.1 MHz frequency band, unless specifically authorized by COSPAS/SARSAT through the Federal Communications Commission and/or Industry Canada. A modular design allows each of the transmitter's modules; MT-3 Transmitter Board, MT-3 Audio Processor, UT3/400 Amplifier, and OS-3H400 Synthesizer Module to be individually assembled and tested. This facilitates construction, tuning, maintenance as well as troubleshooting procedures. The synthesizer module can be programmed to have up to 16 channels exclusive to one frequency band. The UT-3 406 - 512 MHz Transmitter is designed to interface with Daniels Electronics' MT-3 Repeater System while maintaining MT-2 System compatibility. Both repeater systems are characterized by dependable, low maintenance performance under the most severe environmental conditions. 1.2 Manual Organization The organization of this manual reflects the modular makeup of the UT-3 product line. Each module is fully described within its respective submanual, all of which are contained within this document. In general, each submanual contains: 1. A functional description and specification summary, 2. A detailed technical description (Theory of Operation) and 3. Assembly, setup and alignment procedures relevent to that particular module. The module manuals are as follows: Note: material presented in a given "submanual" may include information related to other module versions not directly applicable to the UT-3 406 - 512 MHz Transmitter family (eg, the OS-3H Synthesizer Instruction Manual covers models from 29 MHz to 512 MHz). UHF Transmitter Instruction Manual UT-3 406 - 512 MHz: This manual provides an overview of the complete transmitter, manual organization and assembly in terms of the other modules. MT-3 Transmitter Main Board Instruction Manual: This manual pertains to the audio processor module, transmitter Main Board and Front Panel Board. Most of the user selectable options are accessed within the Transmitter Main Board module, including channel selection. Since all external connections (including power and signal lines) are made to the Transmitter Main Board, most of the material pertaining to transmitter operation and installation is found here. DANIELS DE ELECTRONICS UHF Transmitter Instruction Manual UT-3 406 - 512 MHz 1-1 UHF Amplifier Instruction Manual UT-3 406 - 512 MHz : The amplifier module provides the final stages of RF power amplification and harmonic filtering for the transmitter.

HISTORY................................................................................................ 7-1 DANIELS DE ELECTRONICS Transmitter Main Board Instruction Manual 1 GENERAL 1.1 Introduction The MT-3 Transmitter Main Board integrates the MT-3 Front Panel Board, MT-3 Audio Processor, Synthesizer or Crystal Controlled Oscillator module, and Amplifier module together to comprise a MT-3 series transmitter (see section 5.1: MT-3 Transmitter Block Diagram). The Front Panel Board and the Audio Processor are soldered directly to the Transmitter Main Board while the Amplifier and the Synthesizer or Crystal Controlled Oscillator module are frequency band sensitive, plug-in modules. Circuitry and jumpers on the Transmitter Main Board control the operation of the modules as well as the overall operation of the MT-3 transmitter. Power and signal connections are made through the 48 pin type 'F' connector on the rear of the Transmitter Main Board where they are then routed to the other MT-3 modules. The front and rear panels are attached to the Transmitter Main Board and together with the extruded aluminum shell, form the transmitter enclosure. 1.2 Performance Specifications 1.2.1 General Type: MT-3 Series Transmitter Compatibility: MT-3 Series Amplifier, OC-3 Crystal Controlled Oscillator module, OS-3 and OS-3H Frequency Synthesizer modules.

DANIELS DE ELECTRONICS 1-2 Transmitter Main Board Instruction Manual 2 THEORY OF OPERATION 2.1 Transmitter Main Board 2.1.1 General DANIELS DE ELECTRONICS Transmitter Main Board Instruction Manual 2-1 3 TRANSMITTER ALIGNMENT 3.1 General Transmitter alignment is simplified by using an M-3 Subrack, SM-3 System Monitor, and RF extender cable to provide transmitter power and signal interconnection. Alternatively, +9.5 Vdc and +13.8 Vdc may be applied directly to a transmitter module through positive connection for the +9.5 Vdc to pins B6 and Z6, for the +13.8 Vdc to pins B2 and Z2, and negative connection to pins B30, Z30, B32, and Z32. Transmitter balanced audio (600 Ω) is available at pins B18 and Z18. 3.2 Repair Note MT-3 Transmitter modules are mainly made up of surface mount devices which should not be removed or replaced using an ordinary soldering iron. Removal and replacement of surface mount components should be performed only with specifically designed surface mount rework and repair stations complete with ElectroStatic Dissipative (ESD) protection. When removing Surface Mount Solder Jumpers, it is recommended to use solder braid in place of manual vacuum type desoldering tools when removing jumpers. This will help prevent damage to the circuitboards. 3.3 Printed Circuitboard Numbering Convention To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a printed circuitboard (PCB) numbering convention in which the last two digits of the circuitboard number represent the circuitboard version. For example: • PCB number 43-912010 indicates circuitboard version 1.0; • PCB number 50002-02 indicates circuitboard version 2.0. All PCB's manufactured by Daniels Electronics are identified by one of the above conventions. 3.4 Recommended Test Equipment List Alignment of the complete transmitter requires the following test equipment or its equivalent. It is assumed that any adjustment of the Transmitter Main Board will also involve the other modules. Dual Power Supply: Oscilloscope / Multimeter: Current Meter: Regulated +9.5 Vdc at 2 A.

In a standard configuration, the only alignment required on the MT-3 Transmitter Main Board for a synthesized transmitter is to set the frequency switches (FSW1, FSW2, FSW3, and FSW4) for the desired channel frequency. FSW1 is the most significant digit of the frequency switches. The switch settings for the desired channel frequency can be found in the channel designation tables. If the transmitter is using a crystal control oscillator module, the switch settings are irrelevant.

When the four pins are aligned with their corresponding hole in the Transmitter Main Board, push the module down, taking care to ensure the connector pins on the bottom of the Synthesizer or Crystal Controlled Oscillator module are not bent. DANIELS DE ELECTRONICS Transmitter Main Board Instruction Manual 3-5 To remove the Enhanced Synthesizer or Crystal Controlled Oscillator module, simply remove the center screw from the module lid and pull the module out. The module should be pulled straight out so that the four alignment pins do not bend or damage the circuitboard. The Low Power Synthesizer uses two tabs soldered to the Transmitter Main Board for mounting. No alignment pins are used. As a result care must be taken to ensure the connector pins on the bottom of the Synthesizer are not bent. To install the low Power Synthesizer module, remove the two of the synthesizer side screws that correspond to the tabs on the Transmitter Main board and install the synthesizer module taking care not to bend the pins. Replace the two side screws; installing them through the tabs to hold the synthesizer module in place. When removing the Low Power Synthesizer module, it is important to gently lift the synthesizer module "straight out" in order to prevent damage to the connector pins. Remove the two side screws holding the sinthesizer module to the tabs. Using a plastic coated lifting tool, such as a small screwdriver with the tip covered in heat shrink material, gently lift the synthesizer module from the Transmitter Main Board by applying pressure in a rotating fashion about four corners of the synthesizer module. Replace the two side screws. 3.8 MT-3 Audio Processor Alignment (Version 1.6) 3.8.1 General Verify the standard factory settings for the MT-3 Audio Processor as given in section 3.5.2 before beginning the standard deviation adjustment procedure. If the transmitter's channel frequency changes, the audio processor should be realigned to optimize the transmitter's performance. The schematic diagram for the audio processor is shown in section 5.4.2 and the component layout is shown in section 5.4.1. 3.8.2 MT-3 Audio Processor Standard Deviation Adjustment Note: clockwise rotation of controls increases signal levels. Connect the transmitter to the radio communications test set and monitor FM deviation, distortion, and audio frequency. Before adjusting the audio deviation, confirm that the transmitter RF output frequency is correct. Connect the 600 ohm input to the incoming audio (pins B18, Z18). Set the audio frequency to 1 kHz at the desired level of -8 dBm. Increase the balance level control (R31) for maximum gain. DANIELS DE ELECTRONICS 3-6 Transmitter Main Board Instruction Manual 4 Turn the transmitter on. Adjust the balance compression level (R38) for compression at ±60% maximum deviation. Set the audio frequency to 2.4 kHz, then adjust the deviation control (R29) for maximum deviation. Reset the modulating frequency to 1 kHz and re-adjust R38 for ±60% maximum deviation. Repeat steps 6 and 7 until both conditions are met. Vary the audio signal from 1 kHz to 3 kHz and measure the positive deviation and then the negative deviation. Adjust the symmetry control (R14) until the ± deviation is symmetrical. The variation between ± deviation levels should not exceed 300 Hz over the 1 kHz to 3 kHz range. 10 Repeat steps 6 and 7 and re-adjust if necessary. 11 Adjust the balanced input level control (R31) until the deviation produced by a 1 kHz tone at -8 dBm falls below ±60% maximum deviation, then adjust R31 so that the deviation increases until compression is observed. The deviation should be ±1.5 kHz or ±3 kHz for narrowband and wideband channels respectively. 12 A 1 kHz tone at -8 dBm input level should produce ±60% maximum deviation. If not, go back to step 4 and make sure the pot is set for maximum gain and repeat the procedure. If so, increasing the input level by +20 dBm should not increase the deviation. This confirms that the AGC action of preamplifier U2 is working. 13 A 2.4 kHz tone at the desired audio input level should produce the maximum deviation. Increasing the input level by +20 dBm should not increase the deviation. This confirms that the limiting action of U4a and U5a is working. 14 Set the audio frequency back to 1 kHz at -8 dBm output. Confirm and record audio distortion with the appropriate filter on the communications test set. 15 Confirm the audio frequency response by referencing all output deviation measurements to a 1 kHz input tone at ±20% maximum deviation (±500 Hz for narrowband or ±1 kHz for wideband). 16 Remove the signal to the balanced input (pins B18, Z18). DANIELS DE ELECTRONICS Transmitter Main Board Instruction Manual 3-7 17 Apply a 1 kHz tone at -8 dBm to the microphone audio input. Set the microphone compression control (R8) to produce ±60% maximum deviation. Reduce the signal to -10 dBm and adjust the microphone input level control (R2) for ±50% maximum deviation. Remove the signal. 18. Apply a 100 Hz tone at -18 dBm to the subtone 1 input and adjust the subtone 1 level control (R42) to produce ±500 Hz deviation. Remove the signal. 3.9 Standard Factory Settings and Jumper Configuration Standard factory settings and the associated jumper configuration for the MT-3 Audio Processor (Version 1.8) are given below. 3.9.1 MT-3 Audio Processor Factory Configuration (Version 1.8) The MT-3 Audio Processor is factory configured as follows: • Maximum Deviation: ±2.5 kHz (12.5 kHz or 15 kHz channel), ±5.0 kHz (25 kHz or 30 kHz channel). • Microphone Input: 1 kHz signal at -10 dBm gives ±50% maximum deviation, 1 kHz signal compression set at ±60% maximum deviation. • Audio Balanced Input: Enabled - pre-emphasis response, 1 kHz tone at -8 dBm gives ±60% maximum deviation. 1 kHz signal compression set at ±60% maximum deviation. • Subtone Input 1: 100 Hz tone at -18 dBm gives ±500 Hz deviation. • All other audio inputs:Disabled. • Time-Out-Timer: 5 minutes ± 30 seconds.

DANIELS DE ELECTRONICS 3-10 Transmitter Main Board Instruction Manual 10 Adjust the balanced input level control (R31) so that the deviation increases until compression is observed. The deviation should be ±1.5 kHz or ±3 kHz for narrowband and wideband channels respectively. 11 Increase the input level (R31) by +20 dBm, it should not increase the deviation more than maximum. This confirms that the AGC action of preamplifier U1 is working. 12 A 2.4 kHz tone at the desired audio input level should produce the maximum deviation. Increasing the input level by +20 dBm should not increase the deviation. This confirms that the limiting action of U4a and U5a is working. 13 Set the audio frequency back to 1 kHz at -8 dBm output.

Reduce the signal to -10 dBm and adjust the microphone input level control (R2) for ±50% maximum deviation. Remove the signal. 16. Apply a 100 Hz tone at -18 dBm to the subtone 1 input and adjust the subtone 1 level control (R42) to produce ±500 Hz deviation. Remove the signal. 3.11 Low Frequency Modulation Configuration Note: the following information originates from Daniels Electronics document number A0361-06. 3.11.1MT-3 Transmitters For transmitters, the LTR™ or DCS signal should be applied to the DIRECT MODULATION input (pin Z28), which is also available on the M-3 and SR-3 motherboards at the control connectors J1, P1, or J7 on pins B20 (TX A DIR MOD) and A20 (TX B DIR MOD). The signal from an LTR™ or DCS encoder should be applied through a 47k resistor to reduce the loading effect of the DIRECT MODULATION input. The signal should be capacitively coupled to avoid pulling the transmitter frequency off centre. Most LTR™ and DCS encoder modules already have a capacitive output. Note that the controller generating the low frequency signal will need to key the transmitter's PTT input. Note that the synthesizer and the audio processor may require modifications as described later in this document.

This allows low frequencies to pass. • Short pins P4-1 and P4-3 (or install J23) together with a short piece of 22 or 24 gauge solid wire and solder (see diagram below). This allows the DIRECT MODULATION DANIELS DE ELECTRONICS 3-12 Transmitter Main Board Instruction Manual input to the transmitter to be used to gain access to the SUBTONE INPUT 2 which connects to the PHASE MOD IN input of a modified synthesizer. • Make sure J13 and J16 are not installed.

Dual microphone and balanced audio compression circuits. On-board multi-configurable temperature compensation to correct for changes in transmitter deviation over temperature caused by changing characteristics of synthesizers and oscillators. A single chip 10th Order Linear Phase Lowpass splatter filter for increased cutoff attenuation responses needed in today’s narrow band environment. The ability to switch between narrow and wideband through a single control line which can be externally controlled. This can be useful when configured as a multi-channel transmitter which uses mixed wide and narrowband frequencies. The ability to easily reconfigure fixed operations from narrow to wideband through simple jumper settings Audio Processor Board Instruction Manual 1-1 A continuous +9.5 VDC supply and a switched +8.0 VDC supply are required to power the module which is normally supplied by the Main Transmitter Board. The 6 audio inputs on the FM Audio Processor are: • • • • • DYNAMIC MICROPHONE INPUT 600 OHM BALANCED INPUT subtone inputs auxiliary input. direct modulation input for data signals. The Audio Processor's balanced input pins are isolated by a transformer (T1) on the Transmitter Main Board. Two audio outputs from the MT-3 Audio Processor are routed to the Synthesizer or Crystal Controlled Oscillator Modules. 1-2 Audio Processor Board Instruction Manual 1.2 Block Diagram (FM Audio Processor) Audio Processor Board Instruction Manual 1-3 1.3 FM Audio Processor Board Pin Connections P3 P4 P2 P1 Surface Mount Side PCB END VIEW +9.5V Mic Input +8V -10 dBm Subtone Input 1 Voice And Subtone Output Balanced Input -18 dBm Low Frequency Direct Mod Output dBm -8 dBm Figure 2 Pin Connection Diagram 1.4 Factory Configuration The MT-3 FM Audio Processor is factory configured as follows: Table 2 Parameter Specification Maximum Deviation ±2.5 kHz (Narrowband), ±5.0 kHz (Wideband). 1 kHz signal at -10 dBm gives ±60% rated system deviation 1 kHz signal compression set at ±84% rated system deviation 1 kHz tone at -8 dBm gives ±60% rated system deviation 1 kHz signal compression set at ±84% rated system deviation 100 Hz tone at -18 dBm gives ±500 Hz (Wideband) ±350 Hz (Narrowband) deviation Disabled Microphone Input Audio Balanced Input pre-emphasis response Subtone Input 1 All other audio inputs 1-4 Factory Configuration Audio Processor Board Instruction Manual 1.5 Turn-on Time This measurement is made with the standard factory settings with a 1 kHz tone applied to the balanced input. The turn-on time is the time it takes the FM Audio Processor to output a stable audio signal to P3-1 from the time its power (+8.0 VDC) is switched on. The turn-on time can be virtually eliminated by configuring the FM Audio Processor for continuous audio standby (see section 1.7 Transmitter Standby Modes). The drawback is that more current is used to enable the audio circuits to minimize the turn on time. The bulk of the delay is in the powering of the compression amplifier. For applications that do not use the compression amplifier, the fast turn on times apply as in the case of data transmission, or audio with no compression. Table 3 1.6 Turn On Time Mode Turn on time Fast turn on – higher current Current save – slower response Approx 1mS Approx 150mS Audio Processor Standby Current 15 mA 450uA Low Frequency Modulation The transmitter has an additional option to address low frequency user modulation requirements. A phase modulated bandwidth from 0 (dc) to 100 Hz (PLL loop filter bandwidth) allows specialized applications such as paging or trunking where a separate low frequency digital/analog modulation channel is required. Low Frequency Modulation allows external access to the low frequency modulation capabilities of the synthesizer module. The DIRECT MODULATION inputs on the J1 control connector of the M-3 motherboard will be used (B20 for TX A, and A20 for TX B). Refer to “Data Modulation and Signalling Applications Manual”, P/N AM20-DMS for specific FM Audio Processor configuration methods. 1.7 Transmitter Standby Modes The MT-3 series transmitters has 8 different standby modes that trade-off standby current consumption for start-up speed. Three of these jumpers are on the Transmitter Main Board : • J6 which always turns on the '+9.5 VDC Switched' supply, • J7 which selects the power source for the MT-3 FM Audio Processor • J18 which selects the enable line for the OS-3 or OS-3H Synthesizer, or OC-3 Crystal Controlled Oscillator module. Additionally, there is a jumper on the FM Audio Processor Board: • JU36 which determines the power hookup for the dual compression amplifiers Audio Processor Board Instruction Manual 1-5 Notes: If FM Audio Processor JU36 is not installed, both microphone and balanced audio compression amplifiers will be disabled. This means that the front panel microphone jack will be disabled for local microphone operations. When in this condition, balanced audio is routed around the compression circuitry via JU11 (installed) with JU1 and JU2 removed.

Five of the audio inputs are used primarily for voice and tone signals. The sixth, the Direct modulation input, is used primarily for data signals. The audio control input is used to switch audio outputs so the transmitter can transmit voice or data. 2.1 FM Audio Processor Outputs Both the audio outputs, Modulation Output (P3-1) and Low Frequency / Direct Modulation Output (P4-2), are gated by audio switches U5 and U6 respectively which are controlled by the Transmit Audio Control Input (P4-4). The audio switches can be operated complimentary to each other so there can ever only be one source modulating the transmitter. In standard configuration, the Modulation Output port is used so switch U5 is always on. 2.2 Modulation Output The Modulation Output port is the output port used by all voice input signals. The voice inputs are passed to U1A and U1B, a dual programmable compandor which is configured as an automatic level control amplifier. Op-amp U3A provides the limiting action for the FM Audio Processor. After the audio signals have been combined limited and buffered, they are filtered by 10th order Linear Phase Lowpass Filter (U4). The output signal from the filter is then level adjusted by the deviation control pot, R29, before buffer amplifier U3D. In special applications, jumper JU6 can be disabled and JU7 enabled, this allows the transmitter to be modulated directly from the auxiliary input. This should not be done without external filtering since jumper JU7 bypasses the limiting and filter circuits. 2.3 Low Frequency / Direct Mod. Output The Low Frequency / Direct Modulation Output port has two functions depending on whether the transmitter is synthesized or crystal controlled. In a synthesized transmitter, this port is used to modulate the synthesizer reference frequency. The frequency response of this port is typically DC to 300 Hz. In a crystal controlled transmitter, this port can be used by the Direct Modulation Input to directly modulate the crystal control oscillator module. The frequency response of this port is essentially flat from DC to 5 kHz with no limiting or filtering. 2.4 Microphone Input The microphone input has an automatically level controlled (ALC) preamplifier U1 whose input level is controlled by R2. The microphone input level control (R2) can accommodate a -25 dBm to 0 dBm input signal. The microphone input is limited and filtered and is output at the standard modulation output port. The microphone input can have a standard 6dB/octave pre-emphasis response or a flat-audio response, jumper JU1 at 'y' and 'x' position respectively. 2.5 Balanced Input The 600 ohm balanced input uses the ALC preamplifier U1B, with input level control pot (R31). The balanced input level control can accommodate a -25 dBm to 0 dBm input. (install JU17 when Audio Processor Board Instruction Manual 2-1 using the lower input levels) Like the microphone input, the balance input is limited and filtered and is output at the standard modulation output port. If no compression is required (i.e.: customer is providing their own), JU11 can be enabled providing a path through R48 (Auxiliary Input Level Control) to amplifier U2C where preemphasis or flat audio can then be selected from its output. 2.6 Auxiliary Input The auxiliary input is a special input and does not have an ALC. This input can be configured for a pre-emphasis response (enable JU9Y) or a flat-audio response (enable JU9X). The level for this input is set by R48. The auxiliary output is normally summed with the voice signals by op-amp U3A, limited, then filtered and output at the standard modulation output port. When jumper JU6 is disabled and jumper JU7 is enabled, the auxiliary input can be used to directly modulate the transmitter. Care should be taken when directly modulating the transmitter with the auxiliary input because the MT-3 transmitters use direct FM modulation and there is no filtering or limiting action provided by the auxiliary input. The input level to the auxiliary input should be -18 dBm and can be driven by one of three inputs: • the balanced input – JU11 • the tone/digital input – JU12 X or Y enabled • the direct modulation input – through JU28 When the 600 ohm balanced input is connected to the auxiliary input, the balanced input level control can be used to adjust the level for the auxiliary input. 2.7 Subtone Inputs There are two subtone inputs available on the FM Audio Processor. Both subtone inputs can be individually configured to be output from the standard Modulation Output port or to be output from the Low Frequency / Direct Modulation Output. In standard configuration, Subtone 1 is summed with the voice signals to be output from the standard Modulation Output port while Subtone 2 is used for DCS. Both subtone inputs have an input level control. 2.8 Direct Modulation Input The Direct Modulation Input is an extremely versatile input. This port is designed to be used for data signals. Depending on the application, the signal can be amplified, AC or DC coupled and output to the Modulation Output or the Low Frequency / Direct Modulation Output port. Please consult the factory for specific jumper settings for your application. 2-2 Audio Processor Board Instruction Manual 3 THEORY OF OPERATION Audio Processor Board Instruction Manual 3-1 4 ALIGNMENT Verify the standard factory settings for the MT-3 FM Audio Processor as given in section 1 before beginning the standard deviation adjustment procedure. If the transmitter's operating frequency is changed beyond the factory recommended bandwidth or if the synthesizer is changed, the FM Audio Processor should be realigned to optimize the transmitter's performance.

It is capable of not only compensating for temperature related level variations within the FM Audio Processor (typically –0.3 to –0.5 dB at –40C) but can also compensate for changes caused by the synthesizer or crystal oscillator module that is not equipped with its own temperature compensation. The factory specification is as follows: Wideband When a 2.4 kHz tone is applied at a level of –8dBm to the balanced input of the transmitter, the transmitter deviation shall be ±4.8 kHz at room temperature and can vary from ±4.5 kHz to ±5.0 kHz from -40ºC to +60ºC. Narrowband When a 2.4 kHz tone is applied at a level of –8 dBm to the balanced input of the transmitter, the transmitter deviation shall be ±2.4 kHz at room temperature and can vary from ±2.25 kHz to ±2.5 kHz from -40ºC to +60ºC. Since the specifications of the components used in the synthesizer or oscillator may change over time, changes to the temperature compensation circuit may be necessary even for the same type of equipment. Contact the factory for more information on values used.

TM Audio Processor Board Instruction Manual 7-1 8 FM AUDIO PROCESSOR PARTS LIST Audio Processor Board Instruction Manual 8-1 9 AM AUDIO PROCESSOR 9.1 Introduction The MT-3 AM Transmitter Main Board integrates the MT-3 Front Panel Board, MT-3 AM Audio Processor, Synthesizer or Crystal Control module and Amplifier module together to make a working MT-3 AM series transmitter. The Front Panel Board and the Audio Processor are soldered directly to the Transmitter Main Board while the Amplifier and the Synthesizer or Crystal Control module are frequency band sensitive, plug-in modules. Circuitry and jumpers on the Transmitter Main Board control the operation of the modules as well as the overall operation of the MT-3 transmitter. Power and signal connections are made to the 48 pin type 'F' connector on the rear of the Transmitter Main Board and are routed to the other modules. The front and rear back plates are attached to the Transmitter Main Board and together with the extruded aluminum shell, as discussed in the assembly section of the Transmitter Manual, form the transmitter enclosure. 9.2 Performance Specifications Type: MT-3 AM Series Transmitter Compatibility: VT-3A Series Amplifier, OCT-3 Crystal Oscillator, OST-3 Frequency Synthesizer.

Audio Processor Board Instruction Manual 9-5 9.3 Audio Specifications Audio Input: Audio Response: Audio Distortion: 9.4 -30 to 0 dBm into a 600Ω balanced load. Flat audio; +1/-3 dB: 300 Hz - 3 kHz Less than 3% -40˚C to +60˚C at 30% modulation, Less than 5% -40˚C to +60˚C at 90% modulation Audio Circuits All of the audio signal conditioning (e.g. limiting, filtering) is performed by the MT-3 AM Audio Processor. The transmitter board routes the audio lines from the backplane connector to the audio processor. The audio lines routed to the audio processor are: a 600 ohm balanced input (pins B18 and Z18), and a MIC AUDIO from the MT-3 FRONT PANEL BOARD. It is here that the MIC audio is processed in the same manner as the 600 ohm balanced audio. The audio processor's balanced input pins are isolated from pins B18 and Z18 by a transformer (T1). Two audio outputs from the MT-3 AM Audio Processor are routed to the VT-3A130 Amplifier. The MT-3 AM Audio Processor is a versatile circuitboard that can provide several types of audio processing. The module also has an on-board programmable push-to-talk (PTT) time-out-timer (TOT) on an attached circuitboard. A continuous +9.5 Vdc supply and a continuous +13.8 Vdc supply together with a switched +8.0 Vdc supply are required to power the module. Refer to section 9.11 "MT-3 AM Audio Processor Component Layout" and to section 9.12 "MT-3 AM Audio Processor Schematic Diagram" for component location and designation references. 9.5 Power Requirements The audio processor can be configured for continuous audio standby or for switched audio standby by the Transmitter Main Board. If fast audio risetime is desired, the transmitter should be operated in standby mode 3 or 4 as specified below. The current for the associated TOT is approximately 4 mA when the transmitter is keyed. 9.6 Transmitter Standby Modes The VT-3A130 Transmitter has four different standby modes that trade-off standby current consumption for start-up speed. The standby modes are determined by three jumpers: jumper J6 which always turns on the '+9.5 Vdc Switched' supply, jumper J7 which selects the power source for the MT-3 AM Audio Processor and jumper J18 which selects the enable line for the OST3A128 Synthesizer Module. 9-6 The actual current and start-up time may depend on the frequncy controlled source (crystal or synthesizer) and amplifier module. The current and start-up times given below are representative values intended only as a guideline. MODE 1: Jumper J6 out - the audio processor is switched by a PTT signal - the synthesizer is switched by a PTT signal - standby current typically 13 mA - start-up time typically 40 ms MODE 2: Jumper J6 in, jumper J7 in the 'y' position, jumper J18 in the 'x' position - the audio processor is switched by a PTT signal - the synthesizer is enabled all of the time - standby current not used in this mode - start-up time not used in this mode MODE 3: Jumper J6 in, jumper J7 in the 'x' position, jumper J18 in the 'y' position - the audio processor is enabled all of the time - the synthesizer is switched by a PTT signal - standby current typically 19 mA - start-up time typically 40 ms MODE 4: Jumper J6 in, jumper J7 in the 'x' position, jumper J18 in the 'x' position - the audio processor is enabled all of the time -the synthesizer is enabled all of the time -standby current typically 163 mA -start-up time typically 12 ms 9.7 Audio Circuitry The MT-3 AM Tx Audio Processor refer to section 9.12 "MT-3 AM Audio Processor Schematic Diagram" has two audio inputs (Microphone input and Balanced input) which can be used to modulate the transmitter. The input signals are combined by R2 and R17 at a compandor U1. U1b controls the input level and makes gain inversely proportional to the input level (say a 20 dB drop in input level will produced a 20 dB increase in gain). The output will remain fixed at a constant level without clipping and distortion. (Automatic Level Control) The input signals are adjusted by the pots R1, R16. The variable gain cell in U1a is used as a voltagecontrolled amplifier so that if the power supply (13.8Vdc) has changed the output level will change in order to keep the modulation of the RF output signal at the same level. The gain control can be adjust by the pot R4. (Automatic Modulation Control) The audio signal then amplifies and filters at U2. The output signal is adjusted by the pot R14. Audio Processor Board Instruction Manual 9-7 9.8 AM Audio Processor Factory Configuration The MT-3 AM Transmitter Audio Processor is factory configured as follows: • Microphone Input: modulations. • Audio Balanced Input: modulations. • Automatic Modulation Control • Automatic Level Control 1kHz tone at -10 dBm gives 50% maximum 1 kHz tone at -8 dBm gives 90% maximum enabled enabled The corresponding jumper settings are: • • • • • • • • • 9.9 Jumper JU1: Jumper JU2: Jumper JU3: Jumper JU4: Jumper JU5: Jumper JU6: Jumper JU7: Jumper JU8: Jumper JU9: 'x' position not installed 'y' position not installed 'y' position 'y' position not installed 'y' position installed Automatic Modulation Control disabled Modulation configuration Automatic Level Control enabled Time-out-time power supply (optional) Voice application Voice application Modulation configuration Automatic Level Control enabled Power AMC and Microphone enabled AM Audio Processor Alignment Verify the standard factory settings for the MT-3 AM Audio Processor as given in section 9.8 before beginning the standard modulation adjustment procedure. If the transmitter's channel frequency changes, the audio processor should be realigned to optimize the transmitter's performance. The schematic diagram for the audio processor is shown in section 9.12 and the component layout is shown in section 9.11. *Note: clockwise rotation of controls increases signal levels 9-8 Before adjusting the audio board, confirm that the transmitter frequency is correct. Unscrew and slide out the case of the transmitter. Locate the Tx Audio Board. Connect the transmitter RF Output to a Radio communications test set. Connect the 600 ohm input to the incoming audio (pins B18, Z18). Set the audio frequency to 1 kHz at the desired level of -8 dBm. Turn the transmitter on. Adjust the pot R16, in order to achieve about 0.700 Vrms at TP4. Adjust the pot R14, in order to achieve about 0.200 Vrms at TP8. Tune the Audio Adjust pot R35 on the Power Amplifier board to obtain 90% modulation. Apply a 1 kHz, -20 dBm input signal and adjust the pot R16 in order to obtain 30% modulation. 10 Apply a 1 kHz, -8 dBm input signal, the modulation should be 90%, observe that the distortion of the transmitted signal is within 5.0%. 11 Slowly increase the input audio signal level to 5 dBm and observe that the modulation does not go over 100%. This step verifies the correct operation of the ALC . 12 Change 13.8Vdc power supply to 10V and then to 17V, the modulation of the output RF signal should remain at the same level of 90% ±7% and distortion should be less then 3%. This step verifies the correct operation of the power regulator on the transmitter amplifier board. 13 Repeat steps 7 and 9 if required. 14 Supply a 1 kHz, -10 dBm signal to the microphone input. (Note the level restriction of 25 dBm to 0 dBm.) 15 Adjust the Microphone Input Level Adjust pot (R1) to achieve 50% of RF signal modulation. Observe that the distortion should be under 5%. 16 Turn off the transmitter. Remove the signal source and replace all the screws.

The amplifier has four distinct frequency ranges: 406 to 430 MHz, 450 to 470 MHz, 470 to 490 MHz and 490 to 512 MHz as well as two distinct output power ranges: 0.5 to 2.0 Watts and 2.0 to 8.0 Watts. The UT-3/400 Amplifier is housed in a machined aluminum case that ensures optimum RF shielding, provides a good ground, and also acts as a heatsink. Additionally, the UT-3/400 Amplifier is equipped with output power and VSWR sensing lines which can be individually configured as open collector or linear outputs. The internal VSWR sensor protects the amplifier from high antenna VSWR by approximately halving the amplifier's RF gain when a VSWR overload condition is present. Output filtering for the UT-3/400 Amplifier is provided by the UT-3/400 Lowpass Filter Board. The lowpass filter assembly is mounted in a separate compartment of the amplifier case in order to provided maximum attenuation of harmonic and other spurious signals.

DANIELS DE ELECTRONICS 1-2 UHF Amplifier Instruction Manual UT-3 406 - 512 MHz 2 THEORY OF OPERATION 2.1 Amplifier Operation DANIELS DE ELECTRONICS UHF Amplifier Instruction Manual UT-3 406 - 512 MHz 2-1 3 UT-3/400 AMPLIFIER ALIGNMENT 3.1 General Connections to the power supply, alarm and transmit enable lines (ENA), are clearly marked on the amplifier case. The amplifier is enabled when the enable line (ENA) is grounded. If the amplifier is installed in the transmitter, alignment is simplified by using an SR-3 Subrack, SM-3 System Monitor, and RF extender cable to provide transmitter power and signal interconnection (see the Transmitter Main Board Manual for details). For complete transmitter alignment, the Transmitter Main Board, Synthesizer, Amplifier, and Audio Processor should be tuned in the aforementioned order. Please refer the corresponding manuals for each module. If the input RF level is not changed, adjustments to the output power and alarm thresholds may be made without removing the amplifier cover. However, in the case of a complete amplifier alignment, the amplifier should be separated from the Transmitter Main Board and the amplifier cover removed to expose all amplifier circuitry. All jumpers and test points are clearly marked. 3.2 Repair Note The UT-3/400 Transmitter is mainly made up of surface mount devices which should not be removed or replaced using an ordinary soldering iron. Removal and replacement of surface mount components should be performed only with specifically designed surface mount rework and repair stations complete with ElectroStatic Dissipative (ESD) protection. When removing Surface Mount Solder Jumpers, it is recommended to use solder braid in place of manual vacuum type desoldering tools when removing jumpers. This will help prevent damage to the circuitboards. 3.3 Recommended Test Equipment List Alignment of the transmitter requires the following test equipment or its equivalent. Dual Power Supply: Oscilloscope / Multimeter: Current Meter: Radio communications test set : VSWR 3:1 mismatch load: coaxial test cable set Alignment Tool: Regulated +9.5 Vdc at 0.1 A. Regulated +13.8 Vdc at 2 A - Topward TPS-4000 Fluke 97 Scopemeter Fluke 75 multimeter Marconi Instruments 2955R JFW 50T-035-3.0:1 three 50 Ω cables of incremental length 20 to 40 cm Johanson 4192 DANIELS DE ELECTRONICS UHF Amplifier Instruction Manual UT-3 406 - 512 MHz 3-1 It is recommended that the radio communications test set be frequency locked to an external reference (WWVH, GPS, Loran C) so that the high stability oscillator may be accurately set to within its ±1 ppm frequency tolerance. 3.4 Printed Circuitboard Numbering Convention To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a printed circuitboard (PCB) numbering convention in which the last two digits of the circuitboard number represent the circuitboard version. For example: • PCB number 43-912010 indicates circuitboard version 1.0; • PCB number 50002-02 indicates circuitboard version 2.0. All PCB's manufactured by Daniels Electronics are identified by one of the above conventions. 3.5 Standard Factory Settings and Jumper Configuration The UT-3/400 Amplifier is factory configured as follows: • Open collector configuration for Output Power Alarm (3 dB drop). • Open collector configuration for Antenna VSWR Alarm (VSWR ≥ 3:1). • Output power of 2 Watts or 6 Watts for low and high power amplifiers respectively. The corresponding jumper settings are: • Jumper JU1: not installed • Jumper JU2: installed • Jumper JU3: installed • Jumper JU4: not installed • Jumper JU5: installed • Jumper JU5: not installed 3.6 Output power alarm - linear output Output power alarm - open collector output Antenna VSWR alarm - open collector output Antenna VSWR alarm - linear output Low power (2 W) transmitters High power (8 W) transmitters UT-3/400 Amplifier Alignment 3.6.1 GENERAL The UT-3/400 Amplifier is a frequency sensitive module that is factory assembled to operate in one of four frequency bands: 406 to 430 MHz, 450 to 470 MHz, 470 to 490 MHz or 490 to 512 MHz. The amplifier is available in a low power version, 0.5 to 2.0 Watts output power, and a high power version, 2.0 to 8.0 Watts output power. Both amplifier versions require 5 dBm of input power and in both versions the amplifiers output power is continuously adjustable over the its respective power range. The UT-3/400 Amplifier provides Output Power and Antenna VSWR Alarm outputs which can be configured for open collector output or linear operation. The DANIELS DE ELECTRONICS 3-2 UHF Amplifier Instruction Manual UT-3 406 - 512 MHz amplifier's output power level, alarm levels, and tuning for the transistor matching circuit in the high power version can be set without detaching the amplifier from the transmitter board. However, if the output power alarm or the Antenna VSWR alarm output configuration requires changing, the UT-3/400 Amplifier must be detached from the MT-3 Transmitter Board. Refer to section 4 page 2 "UT-3/400 Amplifier Component Layout" for the location of solder jumpers JU1 to JU5. 3.6.2 UT-3/400 AMPLIFIER ADJUSTMENT The Amplifier alignment consists of two adjustment procedures; (i) a general set up (section 3.6.2.1) procedure which sets up the proper bias conditions for the RF transistors and (ii) the RF threshold adjustments which set up the desired alarm threshold levels as well as the RF output power. The general alignment procedure is required following major repair operations, changes in RF input levels or large changes in operating frequency (greater than ± 1.0 MHz). The RF output and alarm threshold level adjustments are more easily accessible so that fine adjustments can be made in the field. Depending on user requirements, the RF alarm threshold levels should be checked whenever a significant change in operating frequency (± 0.5 MHz) is made. As the antenna VSWR alarm is dependent on the output power alarm, the output power alarm should always be set first. The order of adjustment should be: The adjustment procedures for the high power and the low power version amplifiers are identical after the matching for transistor Q1 is tuned in the high power version. As the antenna VSWR alarm is dependent on the output power alarm, the output power alarm should always be set first. The order of adjustment should be: 1) High Power Amplifiers Only — Tune the transistor matching circuit at the desired frequency and power. Set the desired output power alarm level (section 3.6.2.2). Set the desired output power level (section 3.6.2.3). Set the desired Antenna VSWR alarm level (section 3.6.2.4). Set the desired overload condition level (section 3.6.2.5). 2) 3) 4) 5) Details for the preceding four steps are outlined below. 3.6.2.1 General Set-Up Connect the transmitter's antenna output connector to the type N input of the radio communications test set through a short section of low loss 50 Ω coaxial cable. Turn all four (4) of the adjustment potentiometers (R7, R21, R36, and R38) fully counterclockwise. DANIELS DE ELECTRONICS UHF Amplifier Instruction Manual UT-3 406 - 512 MHz 3-3 3 Turn on the power to the transmitter. For high power amplifier units, follow steps 5 to 7 below. For low power amplifiers, skip to the Output Power Alarm procedure. Tune the output matching capacitor for maximum output power. This should be approximately 8 Watts. For single frequency applications, tune the input matching capacitor so that +9.5 Vdc current is minimized without sacrificing output power. For wideband applications it is best to tune the amplifier at the highest frequency in the band of interest and then tune the input matching capacitor so that the +9.5 Vdc current never exceeds 1.2 amps over the desired frequency band. For single frequency applications, re-peak the output matching capacitor. For wideband applications it is best to tune the amplifier at the highest frequency in the band of interest and then re-peak the output matching capacitor so that the +13.8 Vdc current never exceeds 1.5 amps over the desired frequency band. 3.6.2.2 Output Power Alarm (Forward Power) Open Collector Output * note: the output power alarm output is factory configured as an open collector output so a pull-up resistor may be required on transmitter pin B26 if one is not already present. Adjust R7, the output power adjustment, to the output power at which the Output Power Alarm is to be activated. Monitor transmitter pin B26, the Output Power Alarm line, and slowly turn R21, the output power alarm adjustment, clockwise until pin B26 goes low. The alarm is now set for the current output power of the transmitter. Linear Output Open the amplifier case to disable (open circuit) jumper JU2 and enable (short) jumper JU1. Monitor transmitter pin B26 with a voltmeter. Adjust R7, the output power adjustment, for full transmitter output power. DANIELS DE ELECTRONICS 3-4 UHF Amplifier Instruction Manual UT-3 406 - 512 MHz 4 Adjust R21, the output power alarm adjustment, so that the voltmeter indicates +7.5 Vdc for full transmitter output power. Turn R7, the output power adjustment, fully counterclockwise. The voltmeter should read approximately +3 Vdc. Disconnect the voltmeter. 3.6.2.3 Output Power Turn R7, the output power adjustment, clockwise to the desired transmitter output power. 3.6.2.4 Antenna VSWR Alarm (Reverse Power) Open Collector Output * note: the antenna VSWR alarm output is factory configured as an open collector output so a pull-up resistor may be required on transmitter pin Z26 if one is not already present. The output power alarm must be set first before the antenna VSWR alarm can be set. Disconnect the radio communications test and terminate the transmitter with the 3:1 mismatch load. Monitor pin Z26, the Antenna VSWR Alarm line, and turn R36 fully counterclockwise. Pin Z26 should be high. Slowly turn R36 clockwise until pin Z26 is pulled low. Put the 50 ohm load back on again, Pin Z26 should go high. The reverse power trip point is now set for a VSWR of 3:1. Linear Output Open the amplifier case to disable (open circuit) jumper JU3 and enable (short) jumper JU4. Monitor transmitter pin Z26 with a voltmeter. Disconnect the radio communications test set and terminate the transmitter with the 3:1 mismatch load. Adjust R36, the VSWR alarm adjustment, so that the voltmeter indicates +5 Vdc for a 3:1 mismatch. DANIELS DE ELECTRONICS UHF Amplifier Instruction Manual UT-3 406 - 512 MHz 3-5 5 Put the 50 ohm load back on again. The voltmeter should read approximately 0 Vdc. Disconnect the voltmeter. 3.6.2.5 Antenna VSWR Overload Disconnect the radio communications test set and so that the amplifier is terminated with an open circuit. Monitor the current from the +9.5 Vdc supply. Adjust R38, the VSWR overload adjustment, clockwise until a noticeable drop in the +9.5 Vdc current occurs. Reconnect the radio communications test set and, the +9.5 Vdc current should return to the previous level. 3.6.2.6 Procedure Verification Verify that the current drawn from the +13.8 Vdc supply is less than 1.5 A and from the +9.5 Vdc supply is less than 1.2 A when transmitting full 8 W RF output power. Turn off the power to the transmitter.

470 MHz 1. GENERAL This is hidden text. 1.1 Introduction The OS-3A/H Synthesizer is a compact, fully shielded and environmentally rugged frequency synthesis module that is the nucleus of every MT-3 synthesized Receiver and Transmitter radio module. The OS-3A/H generates a high stability, low distortion radio frequency signal in one of several frequency bands, including 29 - 50 MHz, 118 - 159.4 MHz, 118 - 174 MHz and 406 - 470 MHz. The OS-3A/H utilizes an internal temperature compensated 9.6 MHz reference to produce a signal stable to ±1 ppm within the temperature range of -40°C to +60°C. Alternately, the OS-3A/H can be disciplined by an external 9.6 MHz or 10 MHz reference of higher stability. The OS-3A/H Synthesizer Module is manufactured in twelve distinct models which cover three primary frequency bands (see section 1.2 below). All synthesizer modules are designed to be easily removed for programming, calibration and/or repair. The synthesizer circuitry is distributed between two printed circuit boards (PCBs) which are isolated yet interconnected via photo-logic optical transceivers that effectively eliminate residual electrical noise between digital and analog circuitry. Further shielding of the synthesizer’s RF filter circuitry is provided by an internal shielded enclosure. 1.2 OS(R/T)-3(A/H) Enhanced Synthesizer Family Models The OS-3A/H Synthesizer Module is utilized in both the MT-3 Receiver and Transmitter product lines. In MT-3 Transmitters, the OS-3A/H synthesizer provides a modulated, low-level RF signal to the Power Amplifier module. In MT-3 Receivers, the OS-3A/H synthesizer provides a low noise local oscillator (LO) signal that either directly drives the mixer circuitry or first drives a buffer amplifier which precedes the mixer circuitry (if a higher LO drive signal is required for enhanced intermodulation capability). There are twelve distinct models within the OS-3A/H Enhanced Synthesizer Family. Note that this manual provides service and operating information for all twelve synthesizer modules. It is extremely important to establish the correct synthesizer model number, as documentation is model-specific. The model number can be found on the synthesizer label, located on the synthesizer module top cover. The twelve synthesizer models that comprise the OS-3A/H Synthesizer family are follows: Frequency Band: 29 - 50 MHz, Common OS-3H0xx Analog Board • OST-3H035 • OST-3H045 • OSR-3H061 - installed in FM transmitter, 29 - 38 MHz RF output. - installed in FM transmitter, 38 - 50 MHz RF output. - installed in FM receiver, 50.4 - 71.4 MHz RF output.

Frequency Band: 406 - 470 MHz, Common OS-3H4xx Analog Board • OST-3H418 • OST-3H460 • OSR-3H440 - installed in FM transmitter, 406 - 430 MHz RF output. - installed in FM transmitter, 450 - 470 MHz RF output - installed in FM receiver, 427.4 - 451.4 MHz RF output. All OS-3A/H Enhanced Synthesizer Modules, regardless of the frequency band, use the same digital PCB and mechanical construction. There are, however, significant differences between the various models when it comes to the analog PCB. There are four different analog PCBs, designed to cover the four frequency bands of 29 - 50 MHz, 118 - 159.4 MHz, 128 - 174 MHz and 406 - 470 MHz.

THEORY OF OPERATION This is hidden text. 2.1 Internal Power and Control (Digital Board) Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 2-1 3. SYNTHESIZER ALIGNMENT This is hidden text. 3.1 General OS(R/T)-3(A/H) enhanced synthesizer alignment is simplified by using a Type 84 subrack and RF extender card/cable of providing receiver or transmitter power and signal interconnection. Alternately, +9.5 Vdc may be directly connected to a receiver or transmitter module with the positive connection on pins B6 / Z6 and the negative connection on pins B30 / Z30 / B32 / Z32. Receiver balanced audio (600 Ω) is available at pins B26 and Z26. 3.2 Repair Note The OS(R/T)-3(A/H) synthesizer employs a large number of surface mount components. Removal and/or replacement of surface mount components should never be performed using an ordinary soldering iron but should only be performed at surface mount rework and repair stations equipped with Electro Static Dissipative (ESD) protection. When removing Surface Mount Solder Jumpers, it is recommended that solder wick braid be used in lieu of vacuum type de-soldering tools to help prevent damage to the printed circuit boards. 3.3 Recommended Test Equipment Alignment of the synthesizer requires the following test equipment, or its equivalent: Power supply - Regulated +9.5 Vdc at 2 A. Phillips PM 2811 Oscilloscope / Multimeter - Fluke 97 Scopemeter Radio communications test set - Marconi Instruments 2965A It is recommended that the radio communications test set be referenced to an external high stability frequency source (WWVH, GPS, Loran C) so that the OS-3A/H internal high stability local oscillator may be accurately set to within its ±1 ppm frequency tolerance. 3.4 OS(R/T)-3(A/H) Synthesizer Factory Configuration The OS(R/T)-3(A/H) Synthesizer is factory configured as follows: •Internal 9.6 MHz reference selected. •VCO modulation (via audio processor) enabled (OST TX versions only) Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 3-1 The corresponding internal synthesizer jumper settings are: • • Digital Board Jumper JU2 not installed Jumper JU1 installed 9.6 MHz internal frequency reference selected AM Multichannel mode selected • • Analog Board Jumper JU1: 'B' position Jumper JU2 not installed Internal frequency reference selected Internal frequency reference selected 3.5 OS(R/T)-3(A/H) Synthesizer Alignment Invisible text 3.5.1 General Under normal circumstances (i.e. a change in operating frequency within the synthesizer’s maximum tuning range), synthesizer alignment is accomplished with the synthesizer installed in the MT-3 Receiver IF/Audio Board or the MT-3 Transmitter Main Board. The alignment procedure involves setting the internal TCXO reference frequency (if one is installed and the internal reference option is enabled). This step is described in "Reference Frequency Alignment", section 3.5.5.5. A change in operating frequency from the initial factory setting that exceeds the synthesizer’s maximum tuning range (Refer to Specifications section 1.3) requires a more involved alignment procedure as described in sections 3.5.2 to 3.5.5. Conversion of a synthesizer from internal reference to external reference or vice-versa is accomplished through selection of jumper JU1 A or B, as appropriate and JU2 (Refer to section 3.5.6). 3.5.2 Synthesizer Test Points Analog Board Component Layout (Top) Common to all synthesizer family members. TP1 TP2 TP3 TP4 +8.0 ±0.3 Vdc. U6 positive regulator output. +5.0 ±0.1 Vdc. U7 positive regulator output. +5.0 ±0.1 Vdc. U8 positive regulator output (always on). PLL error voltage. Normal range is +0.5 to +4.5 Vdc (depending on frequency). Nominally adjusted for +2.3 Vdc (via C24) for center channel. UHF/VHF versions employing integrated VCO modules (OSR-3H440, OST-3H418, OST-3H460, OSR-3A149, OST-3A128) require no adjustment. Digital Board Component Layout (Bottom) TP1 TP2 3-2 +5.0 ±0.1 Vdc.

Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 3.5.3 Synthesizer Removal and Installation The synthesizer module is secured to the main board (MT-3 Receiver IF/Audio Board or MT-3 Transmitter Main board) with a single counter sunk Phillips machine screw accessible from the top cover. Remove this screw to remove the synthesizer module. Using a plastic coated lifting tool, such as a small screwdriver with the tip covered in heat shrink material, gently lift the synthesizer module from the main circuit board by applying pressure in a rotating fashion about the four corners of the synthesizer module. It is important to gently remove the synthesizer module "straight out" in order to prevent damage to the connector pins. Installation of the synthesizer is performed in a reverse fashion. It is important to ensure complete connector pin alignment prior to any application of reinsertion force. Four corner locating pins on the synthesizer housing assist in connector pin alignment during installation and removal. Note: Complete synthesizer alignment can be performed without removing the synthesizer. The alignment procedure starting in section 3.5.5 may now be performed. 3.5.4 Circuit Board Removal Note: Circuit board removal is not required for tuning purposes. Using a vacuum de-soldering station, de-solder connections P1, P2 and P3. Remove SMB connectors J1 and J2 by de-soldering the center pins and removing four M2.0 machine screws. These connection points are shown in the "OS(R/T)-3(A/H) XXX - XXX MHz Analog Board Component Layout (Top)" diagrams. Remove seven M2.0 machine screws and carefully remove the analog circuit board. Removal of the analog circuit board will expose three inter-board wire connections. Carefully remove three ferrite beads and six Teflon washers from the inter-board connection wires. Attempt to maintain the position of the three inter-board wires in order to simplify re-assembly. The digital board may now be extracted by removing four M2.0 machine screws. Follow a reverse procedure to re-assemble. 3.5.5 Frequency Adjustment and Channel Selection Connect a radio communications test set through a short section of low loss 50 Ω coaxial cable to the synthesizer module SMB RF output jack (J2). Select the desired channel number via the BCD frequency selection switches on the MT-3 Transmitter Main board or the MT-3 Receiver IF/Audio board (or through .the Frequency Programming Module). Turn the power off and back on and wait a few minutes for the oscillator to completely stabilize. It should be noted that the internal synthesizer TCXO, if installed, operates continuously (regardless of the TX PTT state) when installed in a transmitter. Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 3-3 The measured RF output signal should be within ±1.0 ppm of the specified oscillator frequency at an output level of +5 dBm. Note that unlocked synthesizer operation will be indicated by an unstable or spurious RF output signal. The "Unlocked" red LED will also be illuminated when the PLL is unlocked. Check that the requested channel number is within the frequency range of the particular synthesizer model. An unlocked condition may be rectified by adjusting the VCO tuning elements as described in the following procedures (no adjustment required for the Multichannel AM Synthesizers). Note that there are variations in alignment procedures between the three synthesizer family members as described in the following sections. 3.5.5.1 VHF OS(R/T)-3H 29 - 71.4 MHz VCO Alignment Refer to the "OS(R/T)-3H 29 - 71.4 MHz Analog Board Component Layout" diagrams and the "OS(R/T)-3H 29 - 71.4 MHz Analog Board Schematic Diagram" on pages 4-1, 4-2 and 4-3 of this manual. Using a high impedance (10 MΩ) DC Voltmeter, measure the PLL control voltage at TP4 located on the synthesizer module analog board (top). Access to TP4 is available through the synthesizer top cover. Using a small standard blade screwdriver, carefully adjust the VCO fine frequency "TUNE" trimmer capacitor C24 until a test point (TP4) voltage of approximately +2.3 Vdc is obtained. PLL loop control voltages below approximately +0.5 Vdc and above approximately +4.5 Vdc will indicate an "out of lock" synthesizer condition. If a test point (TP4) reading of approximately +2.3 Vdc is unattainable through adjustment of C24, then the coarse frequency jumpers, JU2-JU4 require modification in order to pull the VCO tune range within the adjustment range of fine tuning capacitor C24. The top synthesizer cover must be removed in order to gain access to the coarse frequency jumpers. The coarse frequency jumpers (JU2-JU4) may be considered to be a selectable binary weighted capacitor element with JU2 being the most significant "bit" and JU4 being the least significant "bit". The tuning resolution size is ≈12 pF (JU4). If the tuning voltage remains higher than +2.3 Vdc, decrease the tuning jumper setting by 1 "bit" position and re-adjust C24 in an attempt to achieve +2.3 Vdc at TP4. For example, if coarse frequency jumpers JU2-JU4 are all installed and represented by 111 then a decrease by 1 "bit" position (12 pF) is represented by a binary jumper selection of 110; jumper JU4 is not installed and jumpers JU2, JU3 are installed. Continue to decrease the jumper position one "bit" at a time until the synthesizer regains lock with TP4 adjusted (C24) for +2.3 Vdc. If the tuning voltage remains lower than +2.3 Vdc, increase the jumper setting by 1 "bit" position and readjust C24 in an attempt to achieve +2.3 Vdc at TP4. Repeat this procedure until +2.3 Vdc is achieved at TP4. It is important to check the loop control voltage at TP4 when multiple synthesizer channels have been programmed. All channel selections should result in a TP4 voltage within a +1.0 to +4.0 Vdc range. Adjust the fine-tuning capacitor C24 to center multiple channel voltages symmetrically about +2.3 Vdc. Channel selections beyond the tuning range capability of the synthesizer will result in 3-4 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz unlocked operation. The tuning range capability of all synthesizer models is listed in the Specifications section (1.3) of this manual. 3.5.5.2 VHF OS(R/T)-3A 118 - 159.4 MHz Alignment Refer to the "OS(R/T)-3A 118 - 159.4 MHz Analog Board Component Layout" diagram and the "OS(R/T)-3A 118 - 159.4 MHz Analog Board Schematic Diagram" on pages 4-5, 4-6 and 4-7 of this manual. Using a high impedance (10 MΩ) DC Voltmeter, measure the PLL control voltage at TP4 located on the synthesizer module analog board (top). Access to TP4 is available through the synthesizer top cover. VHF synthesizers operating in the 118 - 159.4 MHz frequency range require no frequency adjustment as tuning is microprocessor controlled. (The OST-3A128 and OSR-3A149, covering 118-138 MHz and 139.4 - 159.4 MHz respectively, provide full band coverage without tuning adjustment.) All channel selections should result in a TP4 voltage between +3.1 and +3.5 Vdc. Channel selections beyond the tuning range capability of the synthesizer will result in unlocked operation over the temperature range -40C to +60C. The tuning range capability of all synthesizer models is listed in the Specifications section of this manual. 3.5.5.3 VHF OS(R/T)-3H 128 - 174 MHz VCO Alignment Refer to the "OS(R/T)-3H 128 - 174 MHz Analog Board Component Layout" diagram and the "OS(R/T)-3H 128 - 174 MHz Analog Board Schematic Diagram" on pages 4-9, 4-10 and 4-11 of this manual. Using a high impedance (10 MΩ) DC Voltmeter, measure the PLL control voltage at TP4 located on the synthesizer module analog board (top). Access to TP4 is available through the synthesizer top cover. Using a small standard blade screwdriver, carefully adjust the VCO fine frequency "TUNE" trimmer capacitor C24 until a test point (TP4) voltage of approximately +2.3 Vdc is obtained. Measured PLL loop control voltages below approximately +0.5 Vdc and above approximately +4.5 Vdc will indicate an "out of lock" synthesizer condition. It is important to check the loop control voltage at TP4 when multiple synthesizer channels have been programmed. All channel selections should result in a TP4 voltage within the +1.0 to +4.0 Vdc range. Adjust the fine-tuning capacitor C24 to center multiple channel voltages symmetrically about +2.3 Vdc. Channel selections beyond the tuning range capability of the synthesizer will result in unlocked operation. The tuning range capability of all synthesizer models is listed in the Specifications section of this manual. Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 3-5 3.5.5.4 UHF OS(R/T)-3H 406 - 470 MHz VCO Alignment Refer to the "OS(R/T)-3H 406 - 470 MHz Analog Board Component Layout" diagram and the "OS(R/T)-3H 406 - 470 MHz Analog Board Schematic Diagram" on pages 4-13, 4-14 and 4-15 of this manual. Using a high impedance (10 MΩ) DC Voltmeter, measure the PLL control voltage at TP4 located on the synthesizer module analog board (top). Access to TP4 is available through the synthesizer top cover. The UHF synthesizers operating in the 406 - 470 MHz frequency range employ integrated VCO modules having no external frequency adjustment capability. The OST-3H418, OST-3H460 and OSR-3H440 models cover frequencies from 406 - 430 MHz, 450 - 470 MHz and 427.4 - 451.4 MHz respectively and provide full band coverage without tuning adjustment. For the OST-3H418, measured PLL control voltages below approximately +0.5 Vdc and above approximately +4.5 Vdc will indicate an “out of lock” condition. For the OSR-3H440 and the OST-3H460, measured PLL control voltages below approximately +1.0 Vdc and above approximately +7.0 Vdc will indicate an “out of lock” condition. It is important to check the loop control voltage at TP4 when multiple synthesizer channels have been programmed. All channel selections should result in a TP4 voltage within the +0.5 to +4.5 Vdc range for the OST-3H418. The TP4 voltage for the OSR-3H440 and the OST-3H460 should be within the +1.0 to +7.0 Vdc range. Channel selections beyond the tuning range capability of the synthesizer will result in unlocked operation. The tuning range capability of all synthesizer models is listed in the Specifications section of this manual. 3.5.5.5 Reference Frequency Alignment Adjust the synthesizer TCXO fine frequency potentiometer RV1 until the correct output frequency is achieved. Access to this potentiometer is through an opening in the synthesizer top cover. A RF power level of approximately +5 dBm should be measured at the synthesizer module output connector and the frequency should be within ±1 ppm of the desired operating frequency. Reference frequency adjustments should be made at room temperature (+25°C) after a ten minute stabilization period. 3-6 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 470 MHz 3.5.6 Jumper Configuration Solder jumpers are clearly marked on both synthesizer digital and analog circuit boards. Refer to the "OS(R/T)-3(A/H) Digital Board Component Layout (Bottom)" diagram on page 4-17 of this manual and the applicable "OS(R/T)-3(A/H) Analog Board Component Layout (Top)" diagram on page 4-18 for jumper locations. The following list details the required jumper configuration for the two synthesizer operating modes: 1) Internal reference. Install jumper JU1-B, on the Analog Board (Standard). The internal temperature compensated crystal oscillator (TCXO) provides the reference signal with a stability of ±1 ppm from -30°C (Optional -40°C) to +60°C. 2) External reference input. Install jumper JU1-A and JU2 on the Analog Board. This mode is used in applications requiring better than ±1 ppm frequency stability. An external reference signal must be provided at synthesizer SMB connector J1. 3) Reference Frequency Select. Install jumper JU2 on the Digital Board to select a 10.0 MHz reference frequency. When not installed, the reference frequency is by default 9.6 MHz. JU2 must not be installed when using the internal 9.6 MHz TCXO reference. JU2 is used by the microcontroller to establish the correct reference frequency division ratio. (Located on the Digital Board; The Synthesizer module must be removed to change jumper JU2.) 4) AM Multichannel Synthesizer Select. Install jumper JU1 on the Digital Board to select and enable the AM Multichannel Synthesizer with Frequency Select Handle. Caution: Care must be exercised when reinstalling the synthesizer module on the Transmitter Main board or the IF/Audio board. Pay careful attention to pin alignment before pressing the synthesizer module into its mating sockets.
