*GMRS handheld units are limited to 5W of power per FCC SAR limits (measures the ERP – Effective Radiated Power) These channel number designations are not always uniform across the board, for Midland Radio Corporation these are Channel 15RP – 22RP.GMRS repeater capable radios are able to use these frequencies only when communicating with repeater stations.GMRS mobile or base stations power limited to 50W*.Previously GMRS channels, now open to FRS users.5W for either FRS or GMRS – most radios are programmed to only transmit in “low” power modeĤ62 MHz Interstitial Channels (Channels 1-7) Previously FRS only channel, now open to GMRS users.As you see in the chart above, the FCC limits the amount of transmitting power allowed on specific frequencies, with the most notable highlights below:Ĥ67 MHz Interstitial Channels (Channels 8-14) Since September of 2017, FRS and GMRS radios are free to use all channels or frequencies (these words are commonly used interchangeably) available in the range of 462MHz to 467MHz, with some limitations. Here is a helpful chart to look at power limitations and frequencies: GMRS radios are able to communicate with FRS radios on these shared frequencies, as long as they adhere to the FCC power restrictions per channel. This power increase can be utilized fully on channels 15 – 22 where GMRS power is allowed up to 50W (for mobile units, handhelds limited to 5W). The FCC allows for GMRS radios to have significant power increases from FRS radios (which are limited to. For more information on what radio fits best for your needs, check out our buying guide blog. These two radio services use the same frequencies and are able to communicate with one another. This service can also be used by the unlicensed public but only during emergencies and natural disasters.įor the purposes of this article, we will discuss one other radio band, FRS ( Family Radio Service), as it relates to GMRS frequencies and radio programming compatibility. GMRS, or the General Mobile Radio Service, is a mobile UHF two-way communication service in the United States for private use by a licensed user and their extended family.
