[Elecraft] KPA500 with K3s

[Larry (K8UT)]

Expanding on the "two different levels based on the amps OPER/STBY 
switch" described by Dick, the cable enables those two levels per band.

For example, you can adjust the Operate level on 30 meters for a full 
200 legal watts; 300 watts on 10, 15 and 30 into your TA33 Junior 
tri-bander; and the amp's full output into your dipoles.
