Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz). Part of this band is the medium wave (MW) AM broadcast band. The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometers. Frequencies immediately below MF are denoted as low frequency (LF), while the first band of higher frequencies is known as high frequency (HF). MF is mostly used for AM radio broadcasting, navigational radio beacons, maritime ship-to-shore communication, and transoceanic air traffic control.
NOAA Weather Radio (NWR), also known as NOAA Weather Radio All Hazards, is an automated 24-hour network of VHF FM weather radio stations in the United States which broadcast weather information directly from a nearby National Weather Service office. Its routine programming cycle includes local or regional weather forecasts, synopsis, climate summaries or zone/lake/coastal waters forecasts, and can be shortened to specifically include hazardous weather outlooks, short-term forecasts, special weather statements or tropical weather summaries during hazardous weather events. It occasionally broadcasts other non-weather related events such as national security statements, natural disaster information, environmental and public safety statements such as AMBER Alerts, civil emergencies, fires, evacuation orders, and other hazards sourced from the Federal Communications Commission's (FCC) Emergency Alert System. NOAA Weather Radio uses automated broadcast technology that allows for the recycling of segments featured in one broadcast cycle into another and for consistent regular updating of segments to each of the transmitters.
A non-directional beacon (NDB) or non-directional radio beacon is a radio beacon which does not include inherent directional information. Radio beacons are radio transmitters at a known location, used as an aviation or marine navigational aid. NDB are in contrast to directional radio beacons and other navigational aids, such as low-frequency radio range, VHF omnidirectional range (VOR) and tactical air navigation system (TACAN).
The Global Maritime Distress and Safety System (GMDSS) is a worldwide system for automated emergency signal communication for ships at sea developed by the United Nations' International Maritime Organization (IMO) as part of the SOLAS Convention.
WTVN – branded as "News Radio 610 WTVN" – is a commercial news/talk radio station licensed to Columbus, Ohio. Owned by iHeartMedia, the station serves the Columbus metro area. The WTVN studios area located in the McKinley Avenue Corridor northwest of Downtown Columbus, and its transmitter site is near Obetz. In addition to a standard analog transmission, the station simulcasts over the HD digital subchannel of co-owned 93.3 WODC, and streams online via iHeartRadio. WTVN began broadcasting in HD Radio in June 2005, but the in-band on-channel subcarrier was discontinued by 2015.
Radiofacsimile, radiofax or HF fax is an analogue mode for transmitting grayscale images via high frequency (HF) radio waves. It was the predecessor to slow-scan television (SSTV). It was the primary method of sending photographs from remote sites from the 1930s to the early 1970s. It is still in limited use for transmitting weather charts and information to ships at sea.
From early in the 20th century, the radio frequency of 500 kilohertz (500 kHz) was an international calling and distress frequency for Morse code maritime communication. For much of its early history, this frequency was referred to by its equivalent wavelength, 600 meters, or, using the earlier frequency unit name, 500 kilocycles or 500 kc.
NAVTEX, sometimes styled Navtex or NavTex, is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent maritime safety information (MSI) to ships.
The term utility station is used to describe fixed radio broadcasters disseminating signals that are not intended for reception by the general public. Utility stations, as the name suggests, do broadcast signals that have an immediate practical use, by means of analog or usually digital modes; most often utility transmissions are of a "point-to-point" nature, intended for a specific receiving station. Utility stations are most prevalent on shortwave frequencies, though they are not restricted to the shortwave frequencies.

A weather radio is a specialized radio receiver that is designed to receive a public broadcast service, typically from government-owned radio stations, dedicated to broadcasting weather forecasts and reports on a continual basis, with the routine weather reports being interrupted by emergency weather reports whenever needed. Weather radios are typically equipped with a standby alerting function—if the radio is muted or tuned to another band and a severe weather bulletin is transmitted, it can automatically sound an alarm and/or switch to a pre-tuned weather channel for emergency weather information. Weather radio services may also occasionally broadcast non-weather-related emergency information, such as in the event of a natural disaster, a child abduction alert, or a terrorist attack.

MV Ross Revenge is a radio ship, the home of Radio Caroline, as well as having supported Radio Monique and various religious broadcasters. Funded by the Icelandic government, she was constructed in Bremerhaven in 1960 and served as an Icelandic commercial trawler until 1963 when she was sold to the Ross Group fleet, notably taking part in the Cod Wars of the 1970s. Following her decommissioning, she was purchased by Radio Caroline and outfitted as a radio ship, complete with 300-foot (91 m) antenna mast and 50 kW transmitter. Her broadcasts began on 20 August 1983; her final pirate broadcast took place in November 1990. She ran aground on the Goodwin Sands in November 1991, bringing the era of offshore pirate radio in Europe to an end. She was, however, salvaged, and is now maintained by the Caroline Support Group, a group of supporters and enthusiasts.
2182 kHz is a radio frequency designed exclusively for distress calls and related calling operations in the maritime service. It is equivalent to a wavelength of 137.4 metres.
Radiofax was an independent shortwave radio station that broadcast from Ireland between 1988 and 1992. It carried talk programmes on science, technology and media news, as well as contemporary popular music. "Britain's Number Two Shortwave Station," was forced to broadcast from various locations in Ireland because all of their requests for a licence from the British government had been refused. Founder and sponsor Trevor Brook subsequently took the licence battle to the High Court in London and the European Court of Human Rights in Strasbourg.
Radio Caroline is a British radio station founded in 1964 by Ronan O'Rahilly and Allan Crawford, initially to circumvent the record companies' control of popular music broadcasting in the United Kingdom and the BBC's radio broadcasting monopoly. Unlicensed by any government for most of its early life, it was a pirate radio station that never became illegal as such due to operating outside any national jurisdiction, although after the Marine, &c., Broadcasting (Offences) Act 1967 it became illegal for a British subject to associate with it.
