PRC -77 A50 Transmitter-Mixer Module

A50 Transmitter-Mixer Circuit Module

The Circuit Module A50 is the transmitter mixer stage for the PRC-77 / RT-841 radio set. It is a core assembly for proper transmit frequency processing and modulation.

Troubleshooting Tip: A faulty A50 is often the reason why you cannot hear your own voice in the handset while transmitting (missing sidetone/modulation), even if the radio appears to be keyed and transmitting a carrier.
