Sometimes on my Chinese uhf/vhf amateur transceiver, which goes all the way to 520 megahertz, i listen to GMRS/FRS/MURS frequencies. I always hear little kids messing around in the neighborhood on GMRS. Does the FCC really care about this? And what are they going to do about kids buying a Walmart radio and not having a license.
No license is required for FRS frequencies, and the power restriction is one-half (0.5) watt. As GMRS shares some of these frequencies, "licensed" GMRS users can use up to 5 watts on these. Obviously there is no way to differentiate between these users or power levels just by listening in. The higher GMRS-only frequencies are enforceable, but unless there is blatant jamming or deliberate interference it is unlikely the FCC would even bother with it.
