A non-technical friend bought 25+ HTs from a school district. The FCC ID (link below) indicates that they run in 450-520 MHz. I checked all GMRS freqs but they are not transmitting there.
I'm concerned that he may be in violation of FCC regs if he runs these HTs. FCC says they trx either 1 or 4 watts. They have integrated rubber duckies, many of which are broken leaving only a bare coil wire. So that may be harmful also in terms of RF exposure.
I am shopping for a freq counter, but don't own one yet. Trial and error would take forever. Is there another way to find freqs?
