Since MURS uses standard frequencies, most devices that use MURS are compatible with each other. Most analog two-way radios utilize a technology called CTCSS or DCS that helps block out unwanted transmissions. To make MURS two-way radios work together, they must have matching CTCSS or DCS tones. This can usually be done via basic programming ...
The exceptions to this are five specific frequencies that are also part of the Multi-Use Radio Service (MURS), which permits unlicensed operation on these frequencies, provided the output power does not exceed 2 watts. Other frequency bands, such as Citizens Band Radio (CB radio) and Family Radio Service (FRS), may also be used without a license.
Due to the rapid proliferation of "open-banded" export equipment (sold as "10-meter" or "multi-norm" radios) that cover wide frequency ranges, Russia allows for two overlapping sets of 3 bands of 40 channels, for a total of 240 channels. 26.515–26.955 MHz, 26.965–27.405 MHz and 27.415–27.855 MHz make up the first set.

Licensees may use the eight main 462 MHz channels for simplex communication or repeater outputs. [11] The eight main 467 MHz channels may only be used as repeater inputs, [12] in conjunction with the 462 MHz channels as outputs. The repeater input frequencies are exclusive to GMRS, and may be used only by licensed GMRS operators.
Motorola T5320 FRS handheld radio. The Family Radio Service (FRS) is an improved walkie-talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band.
Because period is the inverse of frequency, lower tone frequencies can take longer to decode (depends on the decoder design). Receivers in a system using 67.0 Hz can take noticeably longer to decode than ones using 203.5 Hz, and they can take longer than one decoding 250.3 Hz. In some repeater systems, the time lag can be significant. The lower ...
The military station operator will announce the specific amateur-band frequency being monitored. Usually, MARS stations are located in military and government installations such as The Pentagon , [ 5 ] Fort Huachuca , Andrews Air Force Base , Nellis Air Force Base , as well as Navy bases such as NAS Whidbey Island and several Coast Guard locations.
