The ALC cards process both repeated audio and console audio unless the system is in bypass. I can scan the block and level diagrams if you like. PST is Public Safety Trunk - Ssb
I'm assuming when you say clear voice, you mean analog, (VOICE APPLIED TO THE CONSOLES IS ANALOG AND CONVERTED FROM DIGITAL TO ANALOG - AT PRESENT AEGIS IS NOT DECODED AT THE CONSOLES - PROVOICE IS UNDER CONSTRUCTION AND WILL DECODED AND SENT TO THE C3 MAESTRO CONSOLES) vs either encrypted or unencrypted Voice Guard, AEGIS, or ProVoice. What you are hearing is AGC in the console electronics, and does not affect repeat audio. There may also be some AGC in the microwave (THE MICROWAVE CARRIES 4, T1 CHANNELS CONVERTED FROM ANALOG IN A HARRIS INTRAPLEX MUX SHELF0 or what ever means they use to connect the sites together, but only to keep the levels from exceeding 0dBm. BTW, what is a PST? Not familar with the term. Yahoo!
