GMRS Radio Frequency Chart
Below is a detailed list of these channels, frequencies, and their respective technical specifications.
Summary
| Channel | Frequency (MHz) | Max Power | Bandwidth |
|---|---|---|---|
| 1 | 462.5625 | 5 W | 25 kHz |
| 2 | 462.5875 | 5 W | 25 kHz |
| 3 | 462.6125 | 5 W | 25 kHz |
| … | … | … | … |
| 14 | 467.7125 | 0.5 W | 12.5 kHz |
| … | … | … | … |
| 22 | 462.7250 | 50 W | 25 kHz |
Channels 1 through 7 and 15 through 22 permit a maximum power of 5 W and 50 W, respectively, and operate with a bandwidth of 25 kHz. Channels 8 through 14 are restricted to a lower power of 0.5 W and a narrower bandwidth of 12.5 kHz.
Moreover, GMRS offers repeater channels that allow for extended communication range by utilizing different frequencies for reception (RX) and transmission (TX). The maximum power output for repeater use is 50 W, with an authorized bandwidth of 20 kHz.
| Repeater Channel | RX Frequency (MHz) | TX Frequency (MHz) | Max Power | Bandwidth |
|---|---|---|---|---|
| RPT15 | 462.5500 | 467.5500 | 50 W | 25 kHz |
| … | … | … | … | … |
| RPT22 | 462.7250 | 467.7250 | 50 W | 25 kHz |
Please note that when using these frequencies, the authorized bandwidth is a vital aspect to adhere to for compliance with regulatory standards and how to use them. Ensure your equipment settings align with these specifications to maintain proper operation within the GMRS framework.

Common Queries on GMRS Radio Use
GMRS Channel Standardization and Frequencies
The General Mobile Radio Service (GMRS) is composed of 30 channels, with 22 primary channels shared with FRS services, and 8 additional repeater channels. Frequencies range from 462 MHz to 467 MHz. Channels 1 through 7 are shared with FRS and operate on frequencies between 462.5625 MHz and 462.7125 MHz, while the repeater channels (15-22) use frequencies from 462.550 MHz to 467.725 MHz.
| Channel | Frequency (MHz) |
|---|---|
| 1 | 462.5625 |
| 2 | 462.5875 |
| … | … |
| 22 | 462.7250 |
| *Note: Channels 8-14 are FRS only and not included here. |
Acquiring a GMRS License and Prerequisites
To legally operate a GMRS radio, you must acquire a license from the Federal Communications Commission (FCC). Applicants need to be 18 years or older, fill out the required FCC form, and pay the licensing fee. A single license covers immediate family members as well. No test is required, contrary to amateur radio licensing.
Repeater Channels and Their Operations in GMRS
GMRS repeater channels are specifically from 15 to 22. These channels have dedicated input and output frequencies, usually 467 MHz band frequencies paired with their corresponding 462 MHz band counterparts. Repeaters receive transmissions on one frequency and rebroadcast them on another to extend the communication range.
| Repeater Channel | Input Frequency (MHz) | Output Frequency (MHz) |
|---|---|---|
| 15 | 467.5500 | 462.5500 |
| … | … | … |
| 22 | 467.7250 | 462.7250 |
Permission and Restrictions for Unlicensed GMRS Use
GMRS channels 1-7 can be used without a license only if the radio operates at an output power of 2 watts or less. These are shared with FRS frequencies. However, channels 15-22 and the repeater channels are strictly licensed, and using them without FCC authorization can lead to fines.
Long-Distance Communication in the Trucking Industry
Channel 20, with the frequency of 462.675 MHz, is frequently used for long-distance communication among truckers. This is because it is a repeater channel, allowing for more extensive coverage and clear communication over longer distances.
Preferred Channel for Everyday GMRS Interactions
Channel 16 (462.575 MHz) is often chosen for general use due to its designation as a non-repeater channel, allowing for direct communication without the need for a repeater setup. It’s a good balance between accessibility and minimal interference from other users.
