[Elecraft] Ts-2000 and the KPA

[Phil & Debbie Salas]

You should be keying the KPA with the REMOTE connector on the TS-2000 where REMOTE Pin 2 and Pin 4 are the contacts that short together to key the amp.  I normally also ground pin 2, and use Pin 4 as the amp-key output.  There is also a solid-state output (Pin 7 and ground), but this has the opposite sense of what is needed.  I.e., it puts out 12V on TX and 0V on receive.
