ground to Ring, mic audio to Sleeve, and PTT to Tip
Sounds like somebody screwed up good, Check the cartridge it now may be
blown.

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.
