These extra channels are simply existing FRS/GMRS frequencies with hard coded tones and low power on the FRS-only channels.==Bubble Pack HT Combo Radios==FRS/GMRS consumer radios have been introduced with 22 channels, instead of the 14 channels associated with FRS. On this type of radio, transmitting on shared FRS/GMRS channels 1–7 requires a license if using more than 0.5 watt. Channels 8–14 are strictly license-free FRS channels. Transmitting on GMRS-only channels 15–22 requires a license.These hybrid radios are often referred to as "bubble pack" radios, since they are often packed in a plastic shell, for hanging on a display shelf. Most bubble pack GMRS radios are simplex-only, so they do not function through a repeater. They operate only on the repeater output frequency (GMRS Channels 15 through 22).FRS rules permit only 2.5 kHz (NFM) deviation on the FRS shared channels. GMRS uses ±5 kHz (FM) deviation on the GMRS channels.* [[RadioShack 22 Channel GMRS FRS Base Station 21-1846]]Car / Mobile* Midland MXT100 GMRS MicroMobile 2-Way Radio (5-watt)===Ham Radio Transceiver on GMRS===It is forbidden to use an amateur radio transceiver on GMRS frequencies. Although it is possible to modify many manufacturer amateur radios to operate on GMRS, the amateur operator may lose license privileges by doing so. It is not illegal to perform the modification. It is illegal to use the modified transceiver on these frequencies. It is recommended that you do not perform such modification as to prevent accidental out of band operation.Emergency use: There is a provision in FCC regulation whereas in the event of an emergency such as a life threatening event the use of an amateur radio transceiver out of band is permitted when no other means of communication are available. In this example, the amateur radio being used to find help on a GMRS frequency when no other frequency yielded a response and no phone service is available, said use is permitted. There is a list of some [[Ham Radios Easy to Mod for GMRS]]. It would be very unusual that using an amateur radio on GMRS is the only way to receive help in an emergency. ===GMRS Mobile and Base antennas===Base antenna:* Comet CA-F72GF UHF Base Vertical Antenna. N connector. 440-512 MHz, Tunable.==Use of DMR and other digital formats on GMRS==Use of DMR or other digital formats including dPMR, P25, NXDN is strictly forbidden by the FCC on FRS, GMRS, and MURS frequencies. There are increasing reports of violations in major cities in the United Stations. Most cases involve the use of [[MotoTRBO]] on GMRS repeater frequencies, which is in clear violation of FCC rules. The intermod from digital repeaters creates an unpleasant sound on GMRS receivers and scanners monitoring those frequencies. The illegal use constitutes a problem for radio enthusiasts monitoring analog GMRS and those wanting to legally use GMRS repeaters. All violations should be monitored and reported to the FCC.* PMR446[[Category:FCC Part 95]]
