I have had a similar loss of RX on my K3S. It is cured by turning the
RF control down and then back up. I don't know what causes this and
whether it is hardware or software related. A twist of the knob is all
it takes to fix so I live with it.

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:
