[Elecraft] KAT500 80 meter anomaly

[Andy Durbin]

"Is there a Command that would help to alleviate this behavior?  Or a way to tell the KAT500 to ignore one or more of its preset frequencies that are causing issues?"

How are you telling your KAT500 what frequency to use.  CAT, Counter, or both?

Is you KAT500 in MAN or AUTO mode?

If you are commanding frequency with CAT then FCCS 50000; will make the KAT500 ignore counter frequency for up to 50 seconds and stop any toggling between CAT and counter frequencies.

Commands MTM0; and MTA0; ought to help but, according to my test notes, they don't work as documented.
