GMRS Frequency and Channels List - OneSDR

The General Mobile Radio Service (GMRS) is a licensed radio service that is part of the family radio service bands used in the United States.

It uses channels around 462 MHz and 467 MHz in the UHF band. GMRS is primarily used for short-distance, two-way communications using hand-held radios, mobile radios, and repeater systems.

What is GMRS simplex?

refers to the use of a single frequency for both transmitting and receiving communications on GMRS (General Mobile Radio Service) radios. This mode of operation is different from duplex mode, where separate frequencies are used for transmitting and receiving, often through a repeater.

In simplex mode, communications are direct from radio to radio without the assistance of any infrastructure like a repeater.

What is a GMRS repeater?

It is a device used to extend the range of General Mobile Radio Service (GMRS) communications. It receives a signal on one frequency (the input frequency) and simultaneously rebroadcasts (or repeats) the same signal on another frequency (the output frequency) at a higher power. This allows GMRS radios, which might otherwise be limited by line-of-sight constraints due to terrain or distance, to communicate over much longer ranges.

Additional Notes

Channels 1 through 7 and 15 through 22 can be used with a GMRS license at a higher power (up to 50 watts).
Channels 8 through 14 are typically restricted to 0.5 watt (500 milliwatts) and do not require a license when used within these power limits.
Repeater channels (usually 15-22) are often used to extend the range of communication.

This list is compliant with FCC regulations, which users must follow to ensure proper use and avoid penalties. Always check local regulations and ensure you have the appropriate licensing if required for higher-powered operations or for using repeater channels.

Using GMRS

GMRS (General Mobile Radio Service) requires a license in the United States. The Federal Communications Commission (FCC) issues these licenses.

GMRS is designed for individuals and their family members to communicate with each other over short distances.

Unlike the Family Radio Service (FRS), which is license-free, GMRS can accommodate higher power transmissions and the use of repeaters, which can significantly extend the communication range.

To obtain a GMRS license, you do not need to pass an exam; however, you must apply for the license through the FCC and pay a fee. The license is typically valid for ten years. Once you have a license, it covers the licensee and their immediate family members, allowing them to operate GMRS stations without each family member needing to obtain an individual license.
