[Elecraft] K3/KPA500 question

[Bob Wilson, N6TV]

It's not clear why this feature of the KPA500 is a "PITA," since the
majority of users want the rig and the amp. to always be locked to the same
band.  However, I suppose it could be a problem in a station where antenna
switching is all manual rather than automatic.

In that case, one can change the KPA500 "RADIO" menu from "K3" to "BCD",
and now the band buttons will not change the band of the K3 anymore, but
the amp. will still follow band changes made by the K3.

Hope that helps.
