Fixed/mobile bands. When its not amateur or ham radio, broadcasting, radio navigation beacon systems such as non-directional beacons or NDBs/ADF, DME, VOR, ILS, GPS and other GNSS satellite navigation services (RNAV), land mobile (LMR, PMR, PLMR), military communications systems, 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, industrial and business users, 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, militia and paramilitary groups, military data links, land mobile radio systems and the 26960 kHz - 27410 kHz range includes the legal 40 Citizen's Band channels and 5 remote control and data link channels.
