Cable radio
Cable radio or cable FM is a concept similar to that of cable television, bringing radio broadcasting into homes and businesses via coaxial cable. It is generally used for the same reason as cable TV was in its early days when it was "community antenna television", in order to enhance the quality of over-the-air radio signals that are difficult to receive in an area. However, cable-only radio outlets also exist.
The use of cable radio varies from area to area - some cable TV systems don't include it at all, and others only have something approaching it on digital cable systems. Additionally, some stations may just transmit audio in the background while a public-access television cable TV channel is operating in between periods of video programming. From the late 1970s to the late 1980s, before the advent of MTS Stereo television broadcasts, cable TV subscribers would tune in specific cable FM frequencies that simulcast the television broadcasts in stereo.
A related secondary meaning of the term is any automated music stream - the usual format of cable-only "stations".
United States
The first "commercial" cable radio station in the United States was CABL-FM 108 in California, on the Theta Cablevision system, serving West Los Angeles and surrounding areas. It went live on January 1, 1972, and was run by Brad Sobel, playing what he called "progressive top 40". CABL-FM 108 came into being after Sobel's original venture, K-POT, a bootleg FM station at 88.1 MHz, was silenced by the Federal Communications Commission in November 1971. The illicit station ran for three days until it was shut down, and the event made the front page of the Los Angeles Times and the Los Angeles Herald-Examiner. Because Theta Cablevision charged extra for its FM hookups, CABL-FM 108's potential audience was between 4,700 and approximately 25,000, out of Cablevision's approximately 100,000 subscriber households.The first exclusively cablecasting community radio station was CPVR in Palos Verdes, California, a suburb of Los Angeles. CPVR 95.9 Cable FM radio was on the Times-Mirror cable system, and was started by a group of teenagers who initially practiced being disc jockeys in the homes of two of the founders. Since traditional broadcasting equipment was prohibitively expensive at the time, a young engineer named Tom Hewitt built much of the electronic hardware from scratch.
Mark Speer and Brad Gardner began the venture, which was run as a non-profit youth organization from a studio in the Golden Cove shopping center in Rancho Palos Verdes beginning in March 1972. Even though it was non-profit, it was not subject to the restrictions of terrestrial public radio stations, and thus was able to subsidize expenses by accepting commercial advertising.
Because the staff and audience were part of a highly desirable demographic, advertisers of the day, such as concert promoter Pacific Presentations and local record stores eagerly bought ad time in order to reach such a prime demographic as CPVR had attracted during its history, further enabling CPVR to not only continue operations, but expand into larger studios.
Greg McClure, Jim Sideris, Harv Laser, David Zislis, Richard Hower, Tony Fasola, Dave Chrenko, Kerry Doolin, Liane Benson, Lorraine Dechter, Clyde Stanton and Kathy Bauer were some of the young disc jockeys who helped create the station's legendary style and sound. Unlike Cable 108, CPVR was not only on the FM dial, but was in stereo, and also appeared on the cable system's "barker" channel.
Although the station was only on the "cable" for about two years programming free-form rock and roll, CPVR often scooped its over-the-air competitors, breaking acts such as Bruce Springsteen and Queen, and often premiering landmark albums such as Pink Floyd's The Dark Side of the Moon and Procol Harum's Grand Hotel'' sometimes several weeks before the Los Angeles stations picked them up.
Many of the original staff went on to careers in media. For those involved and those who heard it, this tiny little community rock-and-roll radio station holds a special place in their hearts and minds, often discussed in the same breath as KMET, KPPC, KWST, KRLA, KROQ-FM and KNAC, legendary southern California radio stations in their own right.
For a time, cable radio stations popped up across California and elsewhere in the U.S., most run by high school and/or college students. CCIA, a cable radio station on the campus of California Institute of the Arts, Valencia, California, is one example. But as the founders of these stations grew older and moved on, there was no one to take up where they left off. Eventually all these cable radio stations went dark. Today, where college or community groups might have once considered starting a "cable" radio station, they now look to creating an internet radio station.
On the East Coast the most popular commercial cable radio station was WLHE, started in 1979 in Woburn, Massachusetts. This station was the first commercial cable-only radio station in the country, and ran from 1979 to 1987. Larry Haber, owner and operator, started it. Frank Palazzi and Alan Rupa were the first disc jockeys. Palazzi was known as Frank Fitz, and Alan Rupa was known as Alan James. Mr Haber went by his own name. Other DJs were Jim Fronk, oldies expert Chuck Steven, country music expert Glen Evans, indie rock expert Mark Sawyer, and jazz expert Scott Cavanagh. Larry Haber was the stations first president and general manager, Palazzi served as program director, and Rupa was music director. The station was heard only on Continental Cablevision's local Channel 6 in Woburn, Wilmington, Stoneham, North Reading, and Billerica, Massachusetts.
Canada
In Canada, the Canadian Radio-television and Telecommunications Commission previously required most cable companies to provide cable FM service; those that did were required to convert all local AM broadcast radio stations to cable FM signals. The commission now requires only that campus, community, native radio stations, and one CBC Radio station in each official language, be provided by local cable companies, either via cable FM or digital cable audio channels.Russian Federation
In the former Soviet Union, cable radio was popular and Radio Rossii is reported to have had as many as forty million listeners.Initially the system had one channel that was transmitted as direct audio. The wires and plugs for the system were the same as for standard power wires and plugs which could cause receivers to burn out by attaching to mains socket. During World War II, all RF receivers were confiscated, but cable radio continued operating and, in particular, was used to transmit warnings of aerial bombing. The 1960s saw an enhancement with the addition of two additional channels, using AM on carrier frequencies of 78 and 120 kHz. The installation of this system became mandatory for all new buildings. The system, along with usual broadcasting, was created to inform people of emergencies.
Today, cable radio outlets are installed in all new homes, but many people don't use them or even uninstall the socket and wires inside their units. However, they continue to pay the mandatory fee. These payments can be avoided, but due to bureaucratic procedure it is rarely used.
North Korea
has had a cable radio system sometimes referred to as the 'Third Radio' since the 1940s and it was declared that all cities and villages had been reached by the service in 1975.Operated by the North Korean Ministry of Communications and focusing on music, news, and educational programs. The 'Third Radio' has been mandatory in new apartment blocks since the 1980s and is present in some offices and loud speakers posted in public places.
