I did for a while use that signal for my transverter interface, see http://g4fre.com/k3vhf.pdf and http://g4fre.com/K3_PTT_sw.htm
IT got messy when I changed XVn settings, so I moved onto sniffing the frequency in the rs232 stream and switching transverters based on that, see http://g4fre.com/K3_RS232_sw.htm Dave Ww2r Date: Tue, 21 Jan 2014 18:40:23 -0800 From: Wayne Burdick <[email protected]> To: Phil Theis <[email protected]> Cc: "[email protected]" <[email protected]> Subject: Re: [Elecraft] KPA Aux cable Message-ID: <[email protected]> Content-Type: text/plain; charset=iso-8859-1 Hi Phil, When you're using the K3's low-power transverter output (XVTR OUT), the DIGOUT0 line changes state. We provided this to allow for external hardware decoding of HF vs. transverters. Check page 19 and let me know if this helps.

I will need to do something to alert my switching system that the radio is on HF.
