Re: KX3 Jumper

Hi John,

You are correct in your thinking.  Contact MFJ and they will send the header.  In the meantime you can use two audio cables with 3.5mm plugs at both ends in place of the cable.  The TX Out cable should be stereo.  On the RigPi Audio Board you will see a jumper that connects two pins to provide PTT.  If you want to use the Power On circuitry for the KX3, move the jumper to the other end.  (PTT is provided through CAT.)
