[Elecraft] KPA500 error

[Jack Brindle]

How is the KPA connected? To what? What is the RADIO setting?

If you are using a K3 and have RADIO set to K3, then my guess is you have bad connections in the AUXIO cable. In this mode the KPA. Asks the K3 to switch to the band you request, then it waits for the radio to actually switch. It watches the band signals for this. If they are intermittent or misconnected, it will switch to the wrong band.
Did you move things around recently or bump the cable? Check it for the problem.
