Chris -
The power on -off cycle "cure" does not tally with the below but its worth a
try .
Having just put a KAT3 in my K3 this weekend to replace the KANT3 - from
what you describe - take the top cover off - and if you have the KAT3
tuner - check the two pigtails from the SO239's to the board - make sure
both are plugged in , or not broken at the connector . If its a no tuner
KANT3 - there is just one pigtail. If those are Ok , In either case gently
wiggle the board a bit and see if the sigs re-appear like they do with
tapping the top.(You may have to loosen the standoff at the upper rear side
of the board.) Look carefully at the connector between the board and the
main RF board at the bottom front of the board. Make sure all pins made it
into the socket.
Guess it might also be worthwhile to follow the manual instructions
for"enable" of the KAT3 in the Config menu ( be sure to turn off the K3 for
5 - 10 seconds after the reset and let it re-find /test the device. Maybe
just try that first . (page 47 of my mid 2013 manual )
Good l.uck.

Subject: [Elecraft] K3 intermittent receive issue
Hi friends
I seem to have some issues with my K3 on receive.
It presents as a seemingly complete loss of either RF or IF gain - The S
meter goes dead and there are no signals audible or visible on the S
meter.
After a few seconds usually, everything comes back. Turning the radio off
and on again nearly always cures it.
Happens on all HF bands - doesn't seem related to relays - seems to
respond well to the standard "gentle tap on the top panel" (on the RH side
as you look at the front panel)
It doesn't seem to be related to anything I am doing as I operate.
Any thoughts?
Regards
