Configuration, RRC 1258 / Re: Elecraft K3 Twin with Heil HM-5/HC-5

Dan, I have the RR boxes working FB using a a modified Koss headset that has a Heil HC5 element in it.
The mike is plugged into the Mike input at the side of the K3/0 Mini. For the remote station, the mike
input is FPH.
I found the key was to provide a PTT signal- in my case, I have a footswitch plugged into the PTT jack on the
back of the K3/0 Mini. To use the digital inputs such as FT8, I also had to add a PTT signal into that same
jack or the radio would not send the audio tones (I used WSJT-x to drive a 1-transistor level converter to provide
the PTT signal).
