I feel kind of stupid asking this question, but I'm genuinely not sure of the answer.
I know MDC signalling is not legal on amateur radio, because it is a proprietary (Motorola) protocol (e.g. not an open 'standard').
However, I can't find anything in the rules that prohibits its use on GMRS.
Legal or not legal? (cause I'd really like to use it). I'm leaning towards it being legal but I'd really like some feedback on the topic
Thanks!
