I was in a Radio Shack today that had speaker microphones that sort of looked like they would work with my Motorola GP2000 transceivers. Does anybody knwo how I can find out what speaker microphones will work with the GP2000s. (I use these for amateur radio, NOT business.)

I use the speakermic from the GP300, P1225, P110 series radios. Works fine but i found to fully seat the connector in the radio you kind of have to push hard.

I bought a Pryme SPM-1100 mic that looks like a motorola jedi series spkr mic for my GP's and it works fine.
The Pryme website is currently down, but here's a link to a pdf that shows what they look like. Choose the first link:
