[Elecraft] Use a hammer?

I'd suggest reseating the KAT3 board or at least doing so partially so the connector surfaces are "exercised" a bit. 

Another possibility is that one of the connections from the rear panel ANT1 and ANT2 connectors is not properly seated in the mating connector on the KAT3 board. 

If you've not been inside your K3 before, just remove the top cover. If you need a guide as to which of the plethora of screws are involved, download the KAT3A installation manual from the Elecraft web site by clicking on this hyperlink:

Figure 1 on page 7 shows you which screws to remove and how to "pop" the cover loose so you can lift it off. 
(DON'T GET CARRIED AWAY PULLING THE COVER OFF - You'll need to unplug the speaker wire and you don't want to jerk on the connector). 

Figure 5 on page 9 shows you the one screw that must be removed to free the KAT3 board. Also it indicates one of the rear panel screws that, if removed, will allow you  to move the rear panel back enough to wiggle the board around in its connector. 

Figure 10 on page 12 shows you the two wire connections to the rear panel SO239 connectors I mentioned.

OTOH, a rubber mallet might be more fun if you have visitors although I'm sure that will give Wayne and Eric heartburn and, if one of those antenna connections is loose, will likely stop working. 

As an aside, many years ago I bought a brand new MGA roadster (yeah, I'm an O.T.). Although a thoroughly modern 1960 automobile it had provision for a hand crank to start the engine in an emergency. I had a fun relationship with the agency staff and one time when I was leaving I saw a couple that was considering buying one looking at my car sitting in the lot talking with the salesman. I approached, said "Hi",  took out the crank, put it in the bumper hole and gave it a whirl. The engine started immediately while the couple stood there in amazement. I had to stop and explain that I was "pulling their leg", but I never had to worry about a jump if I left my headlights on! 

The moral of the story is that sometimes the "Armstrong" solutions are more fun.

It kept seeking the correct combination and finally gave up. I tried multiple times (knowing cockpit errors are common at my operating position) with no happiness. I finally "gently " tapped the right rear top and the tuner then operated well as usual. Should I re-seat the module connection points or just use a big hammer? 😳😂73,Griff...N5AG
