1.2.1 Transmitter Module
The Single Channel Transmitter is based on Transceiver Model 90-6R, modified for transmit only
operation. The transmitter module is a low power VHF/AM transmitter which can transmit on a
single pre-programmable synthesized frequency, with 25 kHz channel spacing in the frequency
range 117.975 MHz to 138.000 MHz. The single channel memory set board, module A5A1 is
mounted external to the transmitter module to facilitate ease of frequency programming.
1.2.2 Power Supply Modules - Models SPG-007, SPG-015, SPG-025
The Power Supply Modules provide the DC supply voltage to the transmitter and linear amplifier,
and houses a battery charger which can provide charging and trickle charging to external
rechargeable batteries. Model SPG-007 is for use in the Low Power configurations, Model SPG-
015 is for use in the 15 Watt configurations, Model SPG-025 is for use in the 25 Watt
configurations.
1.2.3 RF Amplifier Modules - Models PA-15, PA-25
The RF Amplifier modules provide 15 Watt (Model PA-15) or 25 Watt (Model PA-25) power
output. The RF Amplifiers are fed by the Low Power RF output from the transmitter module.
1.2.4 Mother Board
The Mother Board provides all interconnection between the two external remote control
connectors, RF Amplifier Module, Power Supply, Remote Control Board, and Transmitter. The
Remote Control Board, RF Isolator and all internal fuses are mounted on the Mother Board.
1.2.5 Remote Control Boards
1. Line Interface Board P/N 923051-1
Provides remote control transceiver operation on 2 wire or 4 wire 600 ohm lines. This
board can be configured to key the transmitter using a 2175 Hz* continuous tone (see
below), plus/minus DC Voltages, ground keying and internal or external DC (15 mA)
current loop keying. Transmit audio is user selectable for two wires or four wires.
*Crystals for tone frequencies other than 2175 Hz may be obtained by special order (i.e.
2380 Hz).
2. Line Interface Board P/N 943180-1
Provides remote control transmitter operation on 2 wire dedicated 600 ohm lines utilizing
the EIA multi-tone keying format found in the Land Mobile Industry. A high level 2175
tone followed by a 1950 Hz guard tone and then a low level 2175 Hz continuous tone is
utilized to key the transceiver. The 943180-1 board can also be jumper strapped for
standard aeronautical 2175 Hz continuous tone operation. DC (15mA) current loop and
ground keying is also supported. However this board does not support 4 wire operation.
NOTE : P/N 923051-1 is the default board supplied in all units. The EIA multi-tone board P/N
943180-1 must be special ordered. To determine which remote card your 92-SC has installed the
Configuration label on the side of the rack mount chassis should be consulted.
