[Elecraft] KAT500

Antenna selection yes, memory no. How shall the tuner know which frequency 
you are tuned to and which memories it should recall? BCD data only encode 
the band, not the frequency. With the bands "sliced" into several segments 
for which tuning memories are stored (presuming the KAT500 works the same as 
the KAT3 and KXAT3 - I would bet on it, hi) you *will* need to "send a dit" 
for the tuner to recognize on which frequency within a band you are and 
which memory must be recalled.

Judging from the auto RF detection / band change routine in the KPA500 I bet 
you will not even recognize the tuner's doing it. But that does not mean it 
does not do it. ;-)
