GM300 Mod levels
Posted: Wed Nov 08, 2017 1:24 pm
Hey Guys,
I have two GM300 vhf radios that appears to be setup for 12.5Khz spacing.
The mod measures 2.5Khz on my service monitor, and going into mod alignment in RSS I max out the mod and all I get is +/- 3khz deviation.
The model number of both radios are: M43GMC29C2AA with a HLD8031A RF Board.
This should be a +/-5Khz capable radio unless I'm missing something.
Any suggestions?
Thanks
P.S. It's entirely possible someone has altered these radios either by software or physically.
