Hello Everyone,

I've been having some issues with the ID-O-Matic 3 on GM300's/Maxtrac/CDM Series radios.

If you have one, the following mods need to be performed, and your issues will go away:

    Removed Capacitor C9 (De-Emphasis Audio Load)
    Short/remove R7
    Short/remove C10

you'll get twice the audio output without compromising any of the filtering/onboard audio path for CWID.
