O A4: Monitors the input/output of the power amplifier. Compares the input/ouptut to selected reference to produce the AGC (VVA Control) in order to maintain a constant output power level. - RF Inhibit (+14.8 VDC): Shuts down the Upconverter by causing the AGC Circuit to use the Limit/Fault Ref Control to induce 40 dB of attenuation, effectively shutting the Upconverter down. If input to the Downconverter exceeds 50 mV the Downconverter will send out an Inhibit to the associated Upconverter, shutting it down. - The Logic: If your receivers are being overdriven, it is more than likely caused by your own transmitter.
