[Elecraft] Kpa 500 problem when auxiliary cable connected ...

[Jack Brindle]

Make sure the RADIO setting in the K3 didn’t get changed away from K3. More specifically, it sounds like it was changed to ANALOG without having the proper pin connected to the Icom’s analog band data signal.

If that isn’t the problem, then I’ll have more questions to see how we might fix the issue.

The kpa500 works fine with the K3 alone, or when I disconnect the auxiliary cable from the K3 ,then I can change bands and use it with the Icom as long as I turn it off and the on again .
