Steve All HF amps the same regardless of the vender.
This pretty much sums it up. http://rin3.blogspot.ca/2014/12/how-to-key-your-amplifiers-with-ts-590g.html You can ignore the pin 7 part if that helps (that is option 2) Pin 2 of the DIN connector goes to ground (or the shield of an RCA cable) Pin 4 goes to the center of the RCA connector you'll need for the amp. What that does is that when the radio goes into Transmit, Pin 4 is grounded and that turns the KPA500 on in TX mode. You don't require any external devices or additional keying relays unless you like to wear a belt and suspenders. :) That should work just fine for decades. I hope that helps, Mike va3mw On Fri, Jan 22, 2016 at 7:54 PM, Steven C Veal <scv...@swbell.net> wrote: > Hello all: > I have a KPA500 on order to use with my Kenwood TS-590SG (and with my > Elecraft KX3).
