"If it were up to me, I would not allow the counter to have priority unless the frequency difference is at least several bin's worth. That way, transmission wouldn't be needlessly interrupted because of the low counter resolution, but the amp would still be protected against erroneous data from the radio"

The same issue exists for the KAT500 and I have proposed that, when CAT tuning is present, that RF frequency override should be based on a time magnitude monitor.  That would mean  small differences between RF and CAT frequency would have to exist for a long time before RF took priority and that a large difference would result in immediate correction of a gross VAT frequency error.  The constants time and magnitude would be adjustable by the user.

I got so annoyed with RF freq taking priority that I have defeated RF tuning for my KAT500.
