@UncleYoda That is my understanding as well. A GMRS "type certified" radio is not supposed to be able to transmit outside of the GMRS frequencies in any form or fashion.
@DeuceoneRadio great job on the research. I guess I have a little different philosophy on continuous power to the radio.
I don't do it much, but sometimes I reach in the truck and turn on the radio briefly. I don't feel like pulling the keys out just for that. Maybe I'm just lazy.
