General Mobile Radio Service. Evolution of the original "Class A" CB service. Calling frequency 462.675 MHz CTCSS 141.3 Hz (sometimes referred to as the "travel channel"). See page for FRS for information about combined FRS/GMRS "bubble pack" radios. As of late 2017, the FCC legalized the 8 "GMRS only" 462 MHz frequencies as part of the FRS service, changing the number of shared frequencies from 7 to 15 and legalizing the use of the higher power "bubble pack" radios for unlicensed FRS use.
Maximum power 50 watts on GMRS is except on shared narrowband channels (FRS channels 1-7) where maximum power is 5 watts. Wideband FM (25 kHz or 20K0F3E) or narrowband FM (11K2F3E, 11K0F3E and several other emissions with even narrower bandwidths) allowed on the 16 GMRS only frequencies for repeater or simplex use. Low power mobile and portable radios generally use narrow FM for compatibility with other handheld FRS radios aimed at the consumer market.
