Basic Operation
After all the cables have been properly connected, the repeater is ready for service.
The transceiver frequency has already been pre-programmed at the factory and is confirmed on the
shipping papers.
To begin basic operation, simply follow these steps.
1) Turn on the power switches for the two AC Power Distribution units (Tripp-Lite, IBAR 12/20 Ultra)
2) Turn on the power breakers on the four RF power amplifiers (MAF860-25S).
3) Turn on the main power switch on the Power Supply Subsystem (075-00028-0001).
After an approximately five minute timeout period, the 13MHz ovenized crystal oscillator will be
sufficiently stabilized, and the repeater will begin modulating and transmitting a pseudo-random DC/MA
signal.
The frequency and other repeater parameters can be checked by connection a computer running a
HyperTerminal and typing in the syspar command.
