Thanks Dan!
I appreciate the response.
I did lookup the mic wiring - that is where I started. ? Uniden BC-645 is a Cobra compatible electret 4 pin mic wiring 1-GND, 2-MIC, 3-PTT, 4-RX - I have 1, 2 and 3 wired correctly, I believe, per my enclosure instructions.??
Sadly - no 3.5mm plug at hand at the moment - but I will wire up the mic and PTT button that came with the kit and test.
Curious if anyone has experience with this mic.
