I believe your GXT600 Midland radio has an internal VOX (voice activation) setting that is used to transmit with an external mic and headset without pressing the radio's PTT. If so, I think you can get the radio to work through your system by switching the GXT600 to the VOX setting. Now, when connected to your PTT switch you are able to use the radio's VOX by opening the transmit circuit with the PTT which allows you to transmit using the internal VOX. I could be wrong here, but I think the problem is that your PTT switch doesn't work the same way that the one that comes with the radio does. My neighbor has his GXT FRS/GMRS set up through his Baehr system and that's what we had to do to get it to work. The only downside is that when you release the PTT the VOX takes a couple of seconds to terminate. As a result, your riding partner will have to wait for the termination of VOX before he/she begins to transmit, or the first part of that transmission will be lost. My neighbor/riding partner and I have had great success with this arrangement.
