[Elecraft] New KPA500 problem.

[Andy Durbin]

"If you try this, be sure to set RADIO = BCD. If it is set to K3 (the default), then tapping a band button results in sending an AuxBus message to the K3, which will then change bands. With no K3 connected, nothing will happen."

Well my KPA500 must be broken.  It changes bands with the band buttons with neither serial port connected and no AUX data source and with K3 selected as radio.  It also changes bands with any other radio type selected.

Time for a code inspection?
