The "Hot" of the audio goes to the sleeve of the plug, and the "hot" of the PTT goes to the tip. The "cold" of the PTT also connects to the ground of the plug, along with the shield. Sorry, but I do not remember for sure what color wire is what. My MEMORY says that red is PTT hot (tip), white is audio hot (sleeve), and black and braid go to ground. But this is memory, and might not be correct as to the colors. It is wired this way whether for PTT or VOX. 73, Ken, W8EK -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, June 11, 2006 11:46 AM To: [email protected] Subject: [drakelist] T4X mic wiring question [EMAIL PROTECTED] made an utterance to the drakelist gang ------- As usual, wiring for mic for my T4X is a mystery for me, I think I have the PTT part wrong maybe. First, I have another mic, a Turner, wired up OK, I use it strictly PTT, not VOX and it works fine. I recently got another mic from Ken, W8EK > > > > Drake "banana" desk microphone > > > > This is the 2 piece desk microphone that was used on the > > > > TR-3 and TR-4 and the 4 line twins.

Having trouble making the wiring happy. T4X manual sez: "connections to plug are: tip - push to talk switch, sleeve is microphone, body is common for both". When it says "sleeve", I'm assuming that's the part wired between the tip and the back / ground part of the plug (in the middle of the plug) ? The cable for the mic I got from Ken has white, red, black, and braid. I had thought tip would be white, red would be body / back, black would be middle / "sleeve". Not behaving correctly however. How should I have it ? I seem to remember something about making a choice between VOX and PTT. Is there some way to be able to do either ? If I have to, I guess my preference is PTT. I also seem to remember that with one of the setups, when I go back to CW I have to screw around with the VOX gain or something...
