[Elecraft] KAT500 Tuner antenna selection stuck in #2 position

[Andy Durbin]

"haven't tried to erase all my settings and revert back to factory default settings...yet. I was only going to do that as a last resort."

There is no reason this should be "last resort".  Save the current configuration, test with factory default configuration, then restore saved configuration.

If default config does not exhibit the problem then you should send the problem configuration to Elecraft support together with an exact series of steps required to reproduce the problem.
