Power Supply Controls and Indicators
The power supply module has three front panel light emitting diode (LED) indicators:
1) ALARM: a RED LED that when illuminated indicates the power supply is no longer operating within its
design specifications
2) STATUS: a GREEN LED that when illuminated indicates the power supply is operating within its design
specifications
3) FAN: a RED LED that when illuminated indicates the power supply fan is no longer functioning per its
design specifications.
The front panel ON/OFF switch is used to enable or disable the DC outputs of the power supply module.

Receiver Module Overview
The Receiver, which supports three-branch diversity, provides the receiver functions for the Base Radio. The
receiver is a part of the ‘transceiver’ RF board and consists of a front end low noise amplifier section, an on board
pre-selector section, an IF filter section, and a baseband converter section. The receiver Voltage Controlled
Oscillator (VCO) and frequency synthesis circuitry blocks are also part of the receiver section. A digital decoding
section for interface to the control section microprocessor also exists as part of the receiver module.
The receiver interconnects to the control module using an 84-pin flex cable connector. There are no user controls
or indicators on the receiver.
