[Elecraft] My KAT500 is sick :(

[Scott via Elecraft]

Time to ask for advice...

I have off the air at the home shack for 6 months because of work.  I covered up everything, all disconnect from antennas and power.  Now work is back to normal so on my vacation I unpacked the K3, P3, and KAT500 and began hooking all up again--the only difference from before is that I improved the ground system.  

The K3 worked Ok except somehow there were a bunch of errors of modules not working that were not even installed (?), but that was easily fixed and I updated the firmware.  All good.  Same with the P3.

However, the KAT500 does not respond to the utility and is locked on ant. 1.  It does seem to tune, but something is wrong.  I checked with a spare KUSB, but no luck there.  I checked cables, etc., and all seems Ok, so I thought best to ask before trying anything else.

Any ideas where to start?

Thanks and 73 for now.
