Is there an agreed-on way to wire a PTT mike to a "stereo" 3-conductor 1/4"
phone plug/jack? Based on past experience (KWM-2, NCX-3), I'd say it is: Sleeve (ground) -- common to mic audio and PTT switch Tip (end) -- PTT switch, close switch to trip TX relay and transmit Ring (middle of shaft) -- mic audio hot However, I found a nice Shure PTT mike that's got the common ground to Ring, mic audio to Sleeve, and PTT to Tip. Should I rewire this beast, or is this really the "standard"? Hard to imagine audio hot going to Sleeve, but who knows? Hope to reach a conscnsus before I repair the wires on my D-104, one of which has broekn off. Thnx es 73, Mike K. Oscar loves trash, but hates Spam! Delete him to reply to me. |
