Low power mobile and portable radios generally use narrow FM for compatibility with other handheld FRS radios aimed at the consumer market. Wide band FM (25 kHz or 20K0F3E, 16K0F3E or similar) or narrow band FM (11K2F3E, 11K0F3E and several other emissions with even narrower bandwidths) allowed on the 16 GMRS only frequencies for repeater or simplex use. Maximum power 50 watts on GMRS is except on shared narrow band channels (FRS channels 1-7) where maximum power is 5 watts. GMRS license holders are still granted higher transmit power privileges and use of repeaters under the new rules. 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 all 22 channels for simplex use under the FRS rules. See page for FRS for information about combined FRS/GMRS "bubble pack" radios. Calling frequency 462.675 MHz CTCSS 141.3 Hz (sometimes referred to as the "travel channel"). GMRS (and by extension, FRS) evolved out of the original 465 MHz "Class A" CB service.
