[Motorola] Pin-Out & Specs for HMN9083D Motorola mic?

[doc]

I believe this was originally paired with a P10 or P50 but since I
bought it from a vendor at a Hamfest I have no way to know for
sure and have no access to any Motorola manuals.

All I know is the model number HMN9083D and that the
connector has 5 pins.  I just cracked the case and see a tiny
pcb aligned with the ptt button and imagine all of the active
circuitry is on it.

Starting with approximately 600 Ohms and anticipating an audio
compression circuit is a helpful place to start.  Given no additional
information I can probably trace the power, PTT, mic, and speaker
lines ... or so I imagine ... then again there is a tendency to share
some lines in many mics ... sigh.

Thanks! & 73, doc KD4E  ARRL-WCF-SEC
