FCC

The FCC requires a GMRS license as a way to regulate frequencies that are used by two-way radio devices . Before operating a GMRS radio, a consumer must have a valid license.

GMRS radios also require a license from the FCC to operate. That’s in part because they are more powerful . FRS walkie talkies can’t be modified to amplify their signal to reach further distances. GMRS radios, however, can be modified to have a stronger, farther-ranging signal, at least up to 50 watts.16 Şub 2021

A wideband signal has up to 5 khz of deviation, while a narrowband signal can have no more than 2.5 khz deviation. GMRS is wideband , while FRS is narrowband.

The 60 meter band is still a band. It just happens to be used by other radio services, with amateurs in some countries getting privileges to use certain frequencies within the band.

radios as a connector to some professional/business use more powerful radios that I use. Although the max power has been increased to 2 watts on these “bubble-pack” radios for GMRS channels(per FCC 2017), IT IS STILL ILLEGAL to transmit on GMRS channels WITHOUT a license .

Other services that allow similar communications include the General Mobile Radio Service (GMRS) and the Multi-Use Radio Service (MURS). The FRS is authorized 22 channels in the 462 MHz and 467 MHz range , all of which are shared with GMRS.

The General Mobile Radio Service (GMRS) is a licensed radio service that uses channels around 462 MHz and 467 MHz .18 Kas 2021
