[Elecraft] KPA500 not responding to K3

[Don Wilhelm]

I would suspect that there is some pin/wire in that KPA/KAT cable which 
is broken.  When used for your purposes between the K3 and the KAT500, 
it is not used, but is used for the KAT500 to KPA500 connection.  It may 
be wise to replace that cable at some point.  I would at least put a tag 
on it as a reminder that it is "flakey".
