The K3 makes the determination. With RADIO set to K3, the BAND buttons simply send a command to the K3 that says which button was pressed. The K3 then does something. In the case of the AUX button, the K3’s decision is based on what features are installed. If a 2 meter module is installed, the K3 goes to 2 meters. Otherwise it will go to 10 meters. In all cases what the KPA does is determined by the state of the K3’s BAND outputs.
Then there is the other answer - it has provided many, many questions about its use. ;-) - Jack Brindle, W6FB > On Mar 15, 2015, at 11:27 AM, Jim Miller <[email protected]> wrote: > > What purpose does the front panel AUX button serve on the KPA500?
