Pete, There was a similar report on the forum last year from Per-Tore, LA7NO. In an extended email conversation we deduced his problems were caused by failed PIN diodes in one of the T/R switches, which ultimately proved to be the case. His K3 also lost TX power, unlike your situation, so you may have lost only the PIN diode in the RX path. There were many other possible causes suggested by others on the forum around that time (late July 2020) - you might read that thread and try the simple fixes first (e.g., twist and re-seat the TMP connectors) before delving into circuit/component failure possibilities. The old thread is here:
