[Elecraft] Kenwood / KPA500 cable

"but all you need is coax for RF and a cable to connect the rig's Amp Key out to an RCA on the KPA500"

Hi Jim,

I know you, and probably many others, are content to use RF frequency detection but it did not appeal to me.  In fact I disliked it so much that I have invested a lot of effort in creating a controller that configures my KAT500 and KPA500 before any RF is emitted. (It does a lot of other things too)

I don't have a TS-890S, just the much more humble cousin the TS-590S.  My only interest in the cable was to help a TS-890S owner.  The configuration of the keying cable is independent of whether RF detection is used or not.   A proper cable for the TS-590SG and TS-890S would use the active low solid state output of the rig, not the relay output (Especially true since Elecraft take great pride in silent keying).
