IM20-VT3H040CT DANIELS DEELECTRONICS VT-3H040 VHF Enhanced Transmitter Instruction Manual iii 1 GENERAL 1.1 Introduction The VT-3H040 transmitter is a low power, synthesized FM transmitter capable of operating in 20 kHz or 25 kHz channels and within one of two bands: 29 MHz to 38 MHz or 38 MHz to 50 MHz. The transmitter is rated for continuous duty at an RF output power of 3.0 Watt. The RF output power level is preset at the factory. A modular design allows each of the transmitter's modules; MT-3 Transmitter Main Board, MT-3 Audio Processor, VT-3H040 Amplifier and OS3H040 Synthesizer to be individually assembled and tested. This facilitates construction, tuning, maintainance as well as troubleshooting procedures. The synthesizer module can be programmed to have up to 16 channels exclusive to one frequency band. The VT-3H040 Transmitter is designed to interface with Daniels Electronics' MT-3 Repeater System while maintaining MT-2 System compatibility. Both radio systems are characterized by dependable, low maintanence performance under the most severe environmental conditions. 1.2 Manual Organization The organization of this manual reflects the modular makeup of the VT-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 VT-3H040 Transmitter family (eg, the OS-3H Synthesizer Instruction Manual covers models from 29 MHz to 512 MHz). Transmitter Manual: This manual provides an overview of the complete transmitter, manual organization and assembly in terms of the other modules. MT-3 Transmitter Main Board: 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 DEELECTRONICS VT-3H040 VHF Enhanced Transmitter Instruction Manual VT-3H040 VHF Amplifier: The amplifier module provides the final stages of RF power amplification and harmonic filtering for the transmitter. This manual is intended primarily as a reference since the amplifier module is adjusted at the factory. OS-3H040 Synthesizer: This manual pertains to the synthesizer module. Channel selection is described in the 'Transmitter Main Board' Manual. VT-3H040 Channel Designation Table: This document relates operating frequency to the transmitter channel number (see section 2.1). 1.3 VT-3H040 Transmitter Family Models The VT-3H040 line of transmitters has a single RF power output rating of 3.0 Watt, with wide band FM (20 kHz or 25 kHz channels) and employs synthesizer based frequency generation. The two basic (i.e. no options added) band specific models of the transmitter are as follows: VT-3H035-SWA3: VT-3H045-SWA3 29 MHz to 38 MHz 38 MHz to 50 MHz The frequency is determined by the model of synthesizer and by the lowpass filter that is installed in the amplifier module (see the VT-3H040 VHF Amplifier manual for details). A group of channels spanning 38 MHz can be accomodated by one of the models providing that the frequency span does not exceed 1.0 MHz. Model VT-3H035-SWA3 can operate at frequencies up to 38.5 MHz and is the preferred choice when spanning 38 MHz. Consult the factory for futher information regarding operation around this frequency.

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. Note: 1.2 1.2.1 LTRTM is a trademark of E.F.

VT-3H040 VHF Amplifier Instruction Manual IM20-VT3040AMP iii 1 GENERAL 1.1 Introduction The VT-3H040 Amplifier provides the final stage of RF amplification and filtering for the VT-3H040 and VT-3H040 Transmitters. The amplifier operates over one of two distinct frequency ranges; either 29 to 38 MHz or 38 to 50 MHz, depending on which of the two lowpass output filters is installed. The output power is set to 3.0 Watts by means of an externally accessed control. The VT-3H040 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 VT-3H040 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 VT-3H040 Amplifier is provided by the Output Lowpass Filter Board. The Output Lowpass Filter Board is mounted in a separate compartment of the amplifier case in order to provided maximum attenuation of harmonic and other spurious signals. Refer to Section 4.4 "VT-3H040 Amplifier Schematic Diagram” for the amplifier and Section 4.2 for the Output Lowpass schematic diagram. 1.2 Performance Specification Type: MT-3 series VHF Amplifier module.

The OS(R/T)-3H generates a high stability, low distortion radio frequency signal in one of several frequency bands. The OS(R/T)3H utilizes an internal temperature compensated 9.6 or 10.0 MHz reference to produce a signal stable to ±1 ppm within the temperature range of -40°C to +60°C. Alternately, the OS(R/T)-3H can be disciplined by an external 9.6 MHz or 10 MHz reference of higher stability. 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. OS(R/T)-3H Enhanced Synthesizer Family Models The OS(R/T)-3H Synthesizer Module is utilized in both the MT-3 Receiver and Transmitter product lines. In MT-3 Transmitters, the OS(R/ T)-3H synthesizer provides a modulated, lowlevel RF signal to the Power Amplifier module. In MT-3 Receivers, the OS(R/T)-3H 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). Note: This section of the manual provides service and operating information for just the synthesizer modules listed below. It is 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. This section of manual covers the following Synthesizers: OST-3H035 29-38 MHz RF output installed in FM transmitter OST-3H045 38-50 MHz RF output installed in FM transmitter OSR-3H061 50.4-71.4 MHz RF output installed in FM receiver All OS(R/T)-3H 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. Each model’s specific sub-band of operation within a given frequency band is determined through SELECT components on the corresponding analog board.

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 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 Paging Modulator Instruction Manual IM55-CIPM3 2 General Information Performance Specifications Model Number: CI-PM-3 Type: MT-3 Series Paging Modulator Compatibility: MT-3 Series Radio Systems Modulation: 16K0F3E (FM Analog) 14K7F1D (FM Data Transmission) Audio Input: Balanced 600 Ω(tone or voice) Digital Input: Bipolar: RS-232 compatible 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 Frequency Stability: Standard: Optional: Duty Cycle: Continuous, 100% from -40°C to +60°C Audio Response: 0 Hz to 3.4 kHz Maximum Deviation: +/- 50 PPM Analog / Digital PTT Activation: Front panel connector and rear motherboard connection Current Consumption: +13.8 VDC supply: +9.5 VDC supply: ±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). 600 mA power 200 mA steady state 200mA (all options enabled) 80mA (all options disabled) 70mA (LED indicators off).
