[Elecraft] K3 - operation with the KPA500 and KAT500

[Bill W2BLC]

Am I correct that the K3, KAT500, and KPA500 operates seemlessly when 
operating SSB and you QSY? Specifically, is any operator intervention 
(button pushing or tuning) need for QSY from the upper part of the band 
to the lower part of the band (ie: 3975 QSK to 3655). Can I just pick 
the mic and talk? Or, is some manual action required for the change?

Thanks,

Bill W2BLC
