Doug,

Thank you for your help with a power cord.

The radio arrived today without a microphone.

Since I know nothing about the radio, what microphone do you recommend
for this radio?

Thank you again for your help!

The mic is any low-Z, single-button carbon mic. The T-17 or the M-15UR
will work, assuming the mic, itself, is good. The mic that comes with

the
radio set looks like a 50's Motorola mobile mic, so any of those or
similar, good quality carbon mics will also work (and recommended!). The
mic plug is a standard military PL-68 with tip being PTT, ring being mic
hot, and the shell is ground.


Whooooooooeee! I have no idea what you're smoking these days, but the

manual
says that the mike input impedance is 47KOhms. (High impedance dynamic or
crystal mike). There is no Voltage source for the microphone which a

carbon
microphone would require. (That also lets out the use of a non-self

powered
electret mike.) The microphone plug is not a PL-68, which is 3/16 inches

in
diameter, but rather a three terminal 1/4 inch jack. (Stereo plug). You

did
get the connections right.

3-conductor plugs (male) & jacks (female) are also called TRS or
"Tip-Ring-Sleeve" connectors in the pro audio business. Of course,
2-conductor versions would be TS or "Tip-Sleeve" types.
