[Elecraft] KPA500 Band Tracking

[Don Wilhelm]

Ted,

One other observation, it would appear that you are missing the BAND0 
signal at the KPA500.  Make sure the ACC connector on the K3 is tight as 
well as other end at the KPA500 (AUX cable).

If you moved things around on the operating desk, it is possible that 
you incurred some cable damage - you should be able to do a continuity 
check on the BAND0 signal line in the cable.

I then went into the config menu for band map and set 30 meters to IN.   The K3 works perfectly – band switching gives me, in MHz, 3.5 – 7.0 – 10.1 – 14.0 – 21.0 – 28.0 and then cycles back to 3.5  That is also exactly what I expected.
