Yep; Easy enough to do: Wire one's own mic to the common 3-circuit plug. (DONE!) Wayne has offered positive information which confirms your feelings.
And, yes; A common "computer mic" may well NOT have a PTT switch. I was never considering this. Rather than a computer mic, I was thinking along the lines of a retired hand or desk mic, and adapting the mic audio and PTT to a plug that would access the desired ground-mic-PTT connections in the KX3 radio. Again, per Wayne's latest, this is indeed a possibility. Thank you for your input, Don. To all, let's call this case CLOSED. (My typing "speed" is "NOT." -Hence, the added email activities this day have been a very INTERESTING but labor-intensive chore.) Thanks to all who participated. I believe that more than one of us has learned all we need, at least for now.) 73; -Mike- KØJTA On 7/22/64 1:59 PM, Don Wilhelm wrote: > 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.
