I was just wondering if anyone knows the frequency range of a gmrs radio? I'm trying to find out if the handhelds we use around the house could be used to talk to the 2m radios alot of people around here have. I think the 2m's use from 144 to 148 mhz. What do the handhelds use? We have 2 gmrs radios that my dad bought at a pawn shop for use around the house (mainly when we installed the sprinkler system). Thanks for any help.
