[Elecraft] Made a DB15 cable to connect K3 + KAT500, but now Amp is disabled

Steve,

Dick's solution will work, but removing the conductor on pin 10 if your 
cable is an easier solution.

What Dick is saying is that you are using both the pin 10 connection and 
the RCA cable PTT connection between the K3 and the KAT500.  I believe 
your problem results from attempting to use both.  Since the cable pin 
10 will not activate the RCA cable between the KAT500 and your 
amplifier, removing the pin 10 signal from your cable seems to be the 
only reasonable alternative.
