Mike, It appears that the lack of PTT with a 3 circuit microphone is a lack in the microphone (I don't know of any mic with a 3 circuit plug that has a PTT button - these are built for use as computer mics). Wayne has said that one could wire a PTT switch onto a 3 circuit jack - which tells me that the PTT circuit is on the ring connector of the jack. Wayne will correct me if that is wrong. Bottom line as I see it - if you have a microphone and a PTT switch, and you wire it to a 3 circuit plug, you will have AF and PTT - but you would have to wire your own, current computer microphones do not have a PTT switch.
