(1) Shared FRS and GMRS simplex. (2) Shared FRS and GMRS simplex; GMRS repeater output. (3) GMRS repeater input. The output frequency of this repeater input is the input frequency minus 5 MHz. (4) FRS transmissions are limited to bandwidth of 11 kHz with a transmitter deviation of +/- 2.5 kHz. Channels are on 12.5 kHz centers.

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 equipment designed for the Taiwan market in the United States. FRS, 14 channels, 12.5 kHz spacing: 467.5125 MHz; 467.5250 MHz
FRS radios use narrow-band frequency modulation (NBFM) with a maximum deviation of 2.5 kilohertz. The channels are spaced at 12.5 kilohertz intervals. All 22 channels are shared with GMRS radios. Initially, the FRS radios were limited to 500 milliwatts across all channels. However, after May 18, 2017, the limit is increased to 2 watts on ...
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. Part 90 (Business) and Part 95 (GMRS) frequencies are not interchangeable and are not to be used under the same guidelines.

The following is a list of FCC-licensed radio stations in the U.S. state of Pennsylvania, which can be sorted by their call signs, frequencies, cities of license, licensees, and programming formats. List of radio stations
Channels 4 and 5 may use either "wideband" FM (5 kHz deviation; 20 kHz bandwidth) or "narrowband" FM. [5] All five channels may use amplitude modulation with a bandwidth up to 8 kHz. [ 6 ] MURS falls under part 95 and was not mandated for narrow-banding, such as those of Part 90 in the public service bands by January 2013.
