Check for dry joints on the wiring to all of the antenna connectors.

Subject: [Elecraft] KAT-500 Increasingly Erratic
I Have a KAT500/KPA 500 combo that I built as kits two yrs ago. The KPA-500 is a pleasure
to operate but the KAT500 has been increasingly erratic to the point where it no longer
tunes 7Mhz, even connected to a cantenna. The other bands are erratic and sometimes it is
several tries. Powering down and back up helps sometimes. I'm not sure the
"memories" are there. I'm switching between bands multiple times and looking
for tuning action on the radio control panel. Some bands tune well sometimes and other
times they do not. Possible intermittent. Troubleshooting has caused me to look over my
antenna system very carefully, fixing some things and eliminating everything in my (G5RV)
antenna system until I was down to a new piece of coax and the cantenna. So what to do?
All those little relays, is there anything a guy can do on his own?
Thanks de Dave WB7ELY
