Sam,
Not sure which accessory is the KXV3a. I do have the internal tuner and a
G5RV and a tribander hooked to the A and B antenna jacks. I have no amp
and use the G5RV most of the time. I should also mention that everytime
this has happened, it's been right after turning the rig on after it has
been sitting overnight in a chilly shack. It'll arc for a few seconds, only
while transmitting, and then settle down. So far, I haven't noticed any
other anomales in the operation of the rig. Lou WA3MIX
