Thanks to all so many who replied, also off list.
I found the K1 relay on the SUBIN board to be faulty. Ordered a new one

OK, that info helps.
Does the Sub receiver also suffer when sharing the main?
There is a 3db splitter when you share the main antenna, so you should
see that drop in both receives.
When the sub is on AUX antenna, it is using the coax straight out the
back of the sub receiver to either the Aux
Hi Udo;
In addition to what N6TV suggested, also click above and below 12Watts.
You will hear the relay on the KPAIO3 riser board click.
Do that when the main RX is down, or click it a bunch to see if you can
force the problem.
If so, replace that relay.

Does rotating the MAIN RF GAIN knob back and forth make any difference? Or
tapping the ANT or RX ANT buttons a lot to exercise the antenna relays?
I assume both receivers are listening to ANT1, and nothing is connected to
AUX RF or RX ANT.
What happens if you move the coax to ANT2?

Gentleman,
I have a problem with the main receiver on one of my K3s. The main
receiver is between 6 and 8dB worse than the second receiver. The stupid
thing about it: it is not always like that, but the poor sensitivity
comes sometimes creeping or sometimes suddenly. It seems to have
