Some places, you will see references to “all 30 channels” and this refers to all of the channels in Figure 2, including the 15R-22R repeater “listening channels”. Of course, if no repeater is available, the GMRS operator can change channel and now the FRS and GMRS operators can communicate on the channel reserved for repeater transmission. What this means is that a GMRS operator will hear the FRS operator (without benefit of the repeater) and the FRS operator will hear the GMRS operator through the repeater. GMRS can use both and can talk to the repeater on the channel on which the repeater is listening. FRS can only use the frequency on which the repeaters talk. Repeaters use two frequencies, one on which they listen (receive) and one on which they talk (transmit). GMRS can operate on repeater receive frequencies, but FRS cannot. This introduces another difference between the FRS and GMRS services. There is also a label in the left-most column of the table above that says 15R-22R. What FM deviation means to you is, GMRS radios are going to sound about twice as loud and clear as FRS radios operating at the same power level on channels 15-22 and, consequently, GMRS radios will have a better signal-to-noise ratio. The channels are illustrated in the table above, where FM refers to a deviation of 5kHz and NFM means a deviation 2.5kHz. For example, it extends to step-grandchildren and in-laws.īoth services have access to all 22 channels, but there are differences in permitted transmission power and FM deviation between services.
Gmrs repeater license#
The license covers your entire “family.” The word family here is defined broadly. The license is $65 for 10 years with a simple, online application. GMRS (General Mobile Radio Service) covers a much farther range through higher power and the options of external antennas and repeater operation. It offers a shorter range of operation due to low power and antenna restrictions. The ServicesįRS and GMRS are two overlapping radio services defined by the FCC.įRS (Family Radio Service) is free, and no license is required. There is also some buying advice for those who still need to get their radio. Here’s what you need to know about the world of FRS/GMRS to be an effective (and legal) FRS/GMRS operator. We occasionally reference the older rules, however, because most of the radios we have now were designed to operate under the older rules, so some understanding of those rules can be useful. The following describes the features of these services, primarily under the new regulations. These rule changes are basically good news for NETs.
The new rules took effect at the end of Sept 2017. In its May 2017 meeting, the FCC made significant changes to the FRS and GMRS services. The topic of use of FRS/GMRS radios by NET members is rather large, so here is a table of contents Every NET member should have one in their go-kit. FRS/GMRS radios are the go-to radios for most intra-team NET communication.
