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.

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.

DANIELS DE ELECTRONICS iv UHF Transmitter Instruction Manual UT-3 896 - 960 MHz 1 GENERAL 1.1 Introduction The UT-3 896 - 960 MHz transmitter is a low power, synthesized, FM transmitter, capable of operation in 6.25 KHz channels. The transmitter operates in three frequency bands: 896 - 902 MHz, 928 - 935 MHz, and 935 - 960 MHz and power output is adjustable from 0.5W to 3.0W. A modular design allows each of the transmitter's modules: OS-3 896 - 960 MHz synthesizer, UT-3 800/900 amplifier, MT-3 audio processor, and MT-3 transmitter main board to be individually assembled and tested. This facilitates construction, maintenance, as well as troubleshooting procedures. The synthesizer module can be programmed to have up to 16 channels exclusive to one frequency band (896 - 902 MHz, 928 - 935 MHz, or 935 - 960 MHz) making the UT-3 an extremely versatile transmitter. In addition, the UT-3 896 - 960 MHz transmitter is capable of standard modulation or low frequency modulation. The UT-3 896 - 960 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 "sub-manual" may include information related to other module versions not directly appllicable to the 896 - 960 MHz Transmitter family (eg, the Low Current Synthesizer Instruction Manual OS(R/T)-3 covers models from 132 MHz to 960 MHz). UHF Transmitter Instruction Manual UT-3 896 - 960 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-3 896 - 960 MHz 1-1 UHF Amplifier Instruction Manual UT-3 806 - 960 MHz : The amplifier module provides the final stages of RF power amplification and harmonic filtering for the transmitter.

DANIELS DE ELECTRONICS vi 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.

MT-3 Transmitter Board Alignment 3.6.1 General Before proceeding with the transmitter alignment, check that the appropriate jumpers are installed. The standard jumper configuration for the Transmitter Main Board, given in section 3.5.1, is normally employed for transmitter alignment. 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.

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.

SHORT TOP TWO PINS REMOVE R47 REPLACE WITH 10 uF MT3TXMNM7 MT-3 Transmitter Audio Processor (board version 43-911914 through 43-911916) • Install jumpers: JU38Y, JU35Y • Remove jumpers: JU27X, JU27Y, JU31, JU35X, JU37, JU38X • 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 figure 3-1). This allows the DIRECT MODULATION 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. Note that the SUBTONE 2 input should not be used while this modification is in effect. Note also that adjusting R44 has no effect on the deviation of the low frequency signal. MT-3 Transmitter Audio Processor (board version 43-911918) • Contact factory for configuration. 3.11.3Synthesizer and Crystal Controlled Oscillator Refer to the manual for the Oscillator used in your Transmitter for the required Low Frequency Modulation modifications. DANIELS DE ELECTRONICS Transmitter Main Board Instruction Manual 3-13 3.11.4Tuning the Transmitter For all MT-3 transmitters, apply a low impedance source of 20-300 Hz to the Direct Modulation input of the transmitter (Pin Z28 of the 48 pin connector) through a 22 uF capacitor, positive terminal connected to pin Z28. A Marconi 2955 works well for this test. Adjust R44 on the audio processor to the fully clockwise position. • Apply a 100 Hz tone at -8 dBm to the Direct Modulation input of the transmitter (Pin Z28 of the 48 pin connector, and key the transmitter. Adjust the level of the tone until a deviation of 1.5 kHz is acheived. Note that the level required may be anwhere from -10 dBm to 0 dBm depending on the type of transmitter. • Confirm that the frequency response rolls off by checking that the following deviations are observed: (note that the deviation will NOT roll off at 300 Hz if an OC-3 crystal oscillator is used instead of a synthesizer). - 20 Hz tone gives about 700 Hz deviation - 100 Hz tone gives 1.5 kHz deviation - 300 Hz tone gives about 500 Hz deviation • Finally, confirm subtone 1 modulation: set-up for 100 Hz Mod with 500 Hz Dev. - Check 200 Hz Mod, Dev = - Check 300 Hz Mod, Dev = 1.5 (VHF) / 2.0 kHz (UHF) 1.5 (VHF) / 4.0 kHz (UHF) DANIELS DE ELECTRONICS 3-14 Transmitter Main Board Instruction Manual 4 TRANSMITTER INTERCONNECT PIN DEFINITIONS The MT-3 series Transmitter employs a 48 pin Eurostandard connector for interfacing to all transmitter power, audio, and control functions.

935 MHz 1 1.1 GENERAL 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, 406 - 470 MHz and 928 – 935 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 thirteen distinct models which cover five 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 thirteen distinct models within the OS-3A/H Enhanced Synthesizer Family. Note that this manual provides service and operating information for all thirteen 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 thirteen 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. Frequency Band: 928 - 935 MHz, Common OS-3H932 Analog Board • OST-3H932 - installed in FM transmitter, 928 - 935 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 five different analog PCBs, designed to cover the five frequency bands of 29 - 50 MHz, 118 - 159.4 MHz, 128 - 174 MHz, 406 - 470 MHz and 928 - 935 MHz. Each model’s specific sub-band of operation within a given frequency band is determined through SELECT components on the corresponding analog board. 1-2 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 1.3 Performance Specifications Type: Narrow band FM, Single loop synthesizer module utilizing low noise VCO and PLL technology.

All PCB's manufactured by Daniels Electronics Ltd. are identified by one of the following numbering conventions: • • 1-4 PCB number 43-912010 PCB number 50002-02 indicates circuit board version 1.0; or indicates circuit board version 2.0 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 2 2.1 THEORY OF OPERATION Internal Power and Control (Digital Board) Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 2-1 3 SYNTHESIZER ALIGNMENT 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 - 935 MHz 3-1 The corresponding internal synthesizer jumper settings are: 3.5 3.5.1 • • 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 OS(R/T)-3(A/H) Synthesizer Alignment 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, OST-3H932) require no adjustment.

Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 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 - 935 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 re-adjust 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 3-4 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz synthesizer will result in 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 - 935 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 UHF OS(R/T)-3H 928 - 935 MHz VCO Alignment Refer to the "OS(R/T)-3H 928 -935 MHz Analog Board Component Layout" diagram and the "OS(R/T)-3H 928 - 935 MHz Analog Board Schematic Diagram" on pages 4-17, 4-18 and 4-19 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 928 - 935 MHz frequency range employ integrated VCO modules having no external frequency adjustment capability. The OST-3H932 model covers frequencies from 928 - 935 MHz and provides full band coverage without tuning adjustment. For the OST-3H932, measured PLL control voltages below approximately +0.5 Vdc and above approximately +4.5 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-3H932. Channel selections beyond the tuning range capability of 3-6 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz the synthesizer will result in unlocked operation. The tuning range capability of all synthesizer models is listed in the Specifications section of this manual. 3.5.5.6 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. Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 3-7 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 4-20 of this manual and the applicable "OS(R/T)-3(A/H) Analog Board Component Layout (Top)" diagram on page 4-21 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. 3-8 Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 4 ILLUSTRATIONS AND SCHEMATIC DIAGRAMS 4.1 OS(R/T)-3H 29 - 71.4 MHz Analog Board Diagrams 4.1.1 OS(R/T)-3H 29 - 71.4 MHz Analog Board Component Layout (Bottom) DANIELS DE ELECTRONICS Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 4-1 5 5.1 PARTS LISTS OS(R/T)-3H 29 - 71.4 MHz Analog Board Electrical Parts List Enhanced AM/FM Synthesizer Instruction Manual OS(R/T)-3(A/H) 29 - 935 MHz 5-1 6 REVISION HISTORY ISSUE DATE REVISION May 97 • Issue 1 Mar 98 • Changes to the AM Analog board (OST-3A128) to improve performance.
