[Elecraft] Kenwood TS-590SG with KPA500 amp?

All HF amps the same regardless of the vender.

This pretty much sums it up.

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
