I was cleaning up my office and ran across a pair of Motorola NTN8867A handmics that I can't remember when I got or why. My best guess is they were at a thrift store or something.
I'd like to use these on a pair of Yaesu HTs I have, an FT2DR and an FT5DR. Unfortunately natively the handmics seem to have an elongated 2.5mm TRS jack, while as best I can tell the Yaesus use 3.5mm TRRS jacks.
I did open one up to look inside, it looks like it's wired fairly simply:
It looks like the two pinouts aren't crazy-different on the surface if the info I found is accurate, the Motorola appears to be a Talkabout single-pin pinout like this:
while the Yaesu pinout seems to be like this:
The problem I'm having, which is why I've created a thread, is I'm having a devil of a time finding an adapter. Motorola simply used so many connectors that Google is useless, their two-pin 2.5/3.5 connectors come up. Does anyone know of a ready-made adapter that will go from from 1-pin Talkabout to Yaesu? If not then I can either try to replace the cable itself with a 3.5mm TRRS soldered on to the handmic PCB, or buy the necessary stubs to make the adapter while leaving the factory cable intact, but if there is a ready-made adapter it would at least let me test quickly.
