[Elecraft] KAT500 operation?

[Don Wilhelm]

Mike,

Are you using *anything* in addition to the basic cables between the 
K-line units?
If so, try removing all the extras (includes the Keyline interrupter and 
the RCA keying cables if used), and then see if it works as expected.
If it does, then begin putting the other things back in place to 
determine which part is causing the failure.
