Been paroozing the forums and the main site looking for info for decoding this pile of Radius M1225 radio model numbers but I keep getting half way decoded then realize the number I have on the radio isn't an option in the list of possibilities. Perhaps I am just tired, or Murphy is playing games. I also have some Radius CM200's that I seem to be running up the same creek with.
Example:
M1225:
M43DGC90E2AA
CM200:
AAM50KQC9AA1AN
Thanks from a beginner

It's that whole teach a man to fish metaphor, right? Haha
