Fixed/mobile bands. When its not amateur or ham radio, broadcasting, maritime mobile, or aeronautical mobile its FIXED/MOBILE.

Sort of a "catch-all". Of course, aren't all radio transmitters either fixed or mobile???

See also: pirate radio frequencies, HF marine bands, HF aeronautical bands and of course the peskies. The 6765 kHz to 7000 kHz band (43 meters) is a fixed/mobile allocation and is the most popular band for pirate broadcasters in the Americas.

Legal shortwave broadcasters are often found on the upper and lower edges of the shortwave bands that often include the fixed mobile allocations.

The fixed/mobile bands contain a mixture of all sorts of random utility or ute communications, some broadcasters operating outside the shortwave broadcast bands, pirate broadcasters, "peskies" (unlicensed or UNID two-way communications), military voice and data networks, military propagation beacons (letter beacons), government networks such as the Civil Air Patrol, SHARES, SECURE, COTHEN and numerous others, NGOs, drug traffickers, diplomatic stations, fishnet stockings or fishing radio buoys/beacons, spy number stations, over the horizon radar, marine weather transmissions in both voice and fax modes, and dozens of other users. Frequencies in the 25-30 MHz region are also used by freeband CB radio operators and the 26960 kHz - 27410 kHz range includes the legal 40 Citizen's Band channels and 5 remote control and data link channels.

Note: in many countries, the fixed/mobile service will be allocated with primary or secondary protection, to other MF and HF bands, including broadcasting, portions of amateur bands, aeronautical mobile and maritime mobile bands.
