[Elecraft] KX3 External Transverter and ATU TUNE disable optionsuggestion

[Dave]

I'll second Davids request.  I have some transverters that will take a fair 
amount of RF in, like the Spectrum Communications types, but others expect 
quite low levels of RF input and, like the other David, I would be bound to 
forget to turn the internal ASTU off one day...
