GMRS operators are permitted to transmit at up to 50 watts transmitter power output, on the 16 main channels, [13] but transmitting 1 to 5 watts is more common in practice. The interstitial frequencies are in-between the main channels, and the 462 MHz interstitial frequencies may be used for simplex as long as the effective radiated power (ERP ...

Cable-ready channels 6, 95, 96, and 97 have audio carriers which overlap FM radio stations (87.7, 95.7, 101.7 and 107.7). Cable-ready channels 57 to 61 overlap the 70cm amateur radio band and can be used for amateur television. Cable-ready channel 64 is within the Family Radio Service and General Mobile Radio Service (GMRS) band.
Hybrid FRS/GMRS consumer radios have been introduced that have 22 channels. Before May 2017, radios had been certified for unlicensed operation on the 7 FRS frequencies, channels 8–14, under FRS rules. [4] Prior to the 2017 revision, FCC rules required a GMRS license to operate on channels 1–7 using more than 0.5 watts. [2]
These charts also list other frequencies that are not specifically part of the "business band" but are commonly used by businesses. An individual license is still required under GMRS rules. A few manufacturers added these DOT frequencies to Business radios in the 1990s to have more "channels" and aid in selling radios.
Some manufacturers in Taiwan have radios that carry both American FRS and GMRS frequencies, and have additional channels 1 to 99. Channels 1 to 14 are well-known, while channels 15 to 99 are less popular. While radios designed for the Taiwan market have FRS/GMRS frequencies as part of their channel plan, it is still technically illegal to use ...
In addition, the FCC continues to require that all digital transmissions be centred on the channel-centre frequencies, which the Report and Order defines as being 1.5 kHz above the suppressed carrier frequency of a transceiver operated in the upper side-band (USB) mode. As amateur radio equipment displays the carrier frequency, it is important ...
