In contrast to
pirate radio stations which broadcast illegally, border blasters are generally licensed by the government upon whose soil they are located. Pirate radio stations are freebooters from offshore, outside the
territorial waters of the nation they target, or ones that are illegally operating in defiance of national law within its sovereign territory. They also contrast with
shortwave radio broadcasters, which operate on frequencies expressly designated for international broadcasts, whereas border blasters use frequencies designated for domestic broadcasts.
Mexico to U.S. In Mexico and the US, while the federal government of the US did not particularly like them, the stations were allowed to flourish.
W. Lee O'Daniel used a border blaster in his successful campaign for governor of Texas. The US, unlike the UK, has never required a license to listen to broadcast radio or television. The only restriction placed upon border-blasters was a law which prohibited studios in the US from linking by telephone to border-blaster transmitters in Mexico. This law, part of the
Brinkley Act, was introduced in the wake of
John R. Brinkley's fraudulent medical advice program on
XERA. The Brinkley Act remains on the books in the US, but licenses under that act are now routinely granted as long as the station follows applicable US and Mexican regulations. The
pop culture inspired by the border blaster stations is extensive: the 1971
Doors song "The WASP (Texas Radio and the Big Beat)",
ZZ Top's song "
Heard It on the X" (1975), "The Wolfman of Del Rio" by
Terry Allen on his 1979 album
Lubbock (On Everything), 1983's "
Mexican Radio" by
Wall of Voodoo, and 1987's "
Border Radio" movie theme by
The Blasters.
Europe A similar situation developed in Europe, beginning with
Radio Luxembourg after
World War II. The
British government identified these stations as
pirates because the Sunday broadcast was reserved for British listeners (deliberately coinciding with the BBC Sundays of religious programmes). The broadcasts were considered illegal on British soil as these stations were breaking the monopoly of the non-commercial
BBC. (Coincidentally, a large percent of the Republic of Ireland could receive spillover from Northern Ireland, Wales and the west of England BBC TV and radio broadcasts for decades.) Listening to the broadcasts was technically a violation of UK radio-license laws of the day. The same "
radio périphérique" , or "peripheral radio", phenomenon existed in
France from the 1930s until the legalization of private broadcasting in the early 1980s, which allowed
Radio Luxembourg from
Luxembourg,
Radio Andorre and
Sud Radio from
Andorra,
Radio Monte Carlo from
Monaco, and
Europe 1 from
Saarland,
Germany, to begin legally broadcasting signals across international borders. The British government created countermeasures after World War II: the state-owned telephone monopoly prevented studios in Britain from linking by telephone to the transmitters of Radio Luxembourg. These restrictions were mostly lifted following the privatisation and demonopolisation of the UK telephone system. In Slovenia,
TV Koper-Capodistria was especially historically a de-facto semi official border blaster, as its signals can be received well throughout Northeast Italy and some of the first private local stations often retransmitted the signal from Nanos on ch. E27. It was particularly popular in the 70s due to transmitting in color before
RAI did and might have influenced Italy's decision to use
PAL as the color standard. However by the late 1980s and early 1990s it started losing relevance as private TV stations started spreading and eventually blanketing the signal. Likewise, RAI itself was a de facto border blaster, with its TV signals being receivable in modern day Slovenia and Croatia since 1954, when RAI started transmitting on ch. E5 from Monte Venda, two years before the start of TV service in Yugoslavia. Later on, many local and regional private TV stations in Veneto and Friuli Venezia Giulia also became de-facto border blasters due to high power without attenuating the beams towards Slovenia and Croatia. This was also the case for Albania, with many Albanians during Hoxha's rule relying on Italian TV for information on the outside world. For local stations this persisted into the digital era with many maintaining ERPs of hundreds of kilowatts without attenuation towards the horizon, until the late 2022 UHF spectrum reorganizing where the 700 MHz band was freed for mobile networks, as well as most local muxes ceasing transmissions in favor of RAI and Mediaset's local TV muxes. Italian FM stations are still de-facto border blasters, being receivable in coastal Slovenia and Croatia even with very modest antenna setups.
Northern U.S. and Canada Signals of many US and Canada radio stations (and to a lesser extent television outlets) encroach on neighboring territory. Such stations are usually not deemed "border blasters," as their programming is not primarily targeted at listeners and viewers across the border. US and Canadian stations adhere to comparable maximum power levels, and the encroachment is regarded as unintentional and largely unavoidable. However, in areas where a US radio station is close to a significantly larger Canadian metropolitan area (or vice versa), true border blasters do exist. An exception to that general rule is
KRPI located in
Ferndale, Washington. It is owned by BBC Broadcasting, Inc., a Washington state company with studios in
Richmond, British Columbia. The station airs a mixture of music, news and talk focused on the
South Asian communities in
Metro Vancouver. To improve reception of the station within its target market, KRPI applied and received an FCC construction permit to increase its nighttime power from 10 to 50 kilowatts, change the community it served and move its transmitter from Ferndale to
Point Roberts, a community adjacent to the Canada–US border. The move has attracted much criticism from the local citizens of Point Roberts and the adjacent densely populated community of
Tsawwassen, British Columbia, because it would cause harmful
blanketing interference. Another possible exception to that general rule on the Canadian side was
CKLW in
Windsor, Ontario, across the river from
Detroit. Originally licensed as a Class II-B (now Class B) station and always operating in full compliance with the technical specifications and operating rules of its
CRTC licence (i.e., protection of the entire Mexican border nights and protection of co-channel Canadian stations days and nights), CKLW's 50,000-watt directional signal blanketed much of
Michigan and northern
Ohio east to
Cleveland days and nights, and south to Toledo, Lima and Dayton in the daytime. American-owned until 1970 as part of the
RKO General chain (along with such other top 40 powerhouses as
KHJ in
Los Angeles and
KFRC in
San Francisco), it functioned essentially as a Detroit-market station during the 1960s and 1970s. Its Motown-flavored personality Top 40 format made it one of the most highly rated stations in the
Midwestern US. The decline of AM radio as a music source in the 1970s, combined with new Canadian government rules imposing domestic ownership of and
minimum domestic music content on Canadian-based stations, made it difficult for CKLW to continue to compete for listeners with Detroit-based, US-licensed FM music stations, which offered clean stereo sound and faced no program content or music playlist restrictions. CKLW abandoned the Top 40 format and its efforts to compete in the Detroit market in the 1980s. Today it is a news/talk station aimed largely at an Ontario audience, though still containing a significant amount of American syndicated talk.
WLYK is another example of a border blaster, broadcasting from a transmitter in New York State and serving the adjacent
Kingston, Ontario, area; its operator
My Broadcasting Corporation (through its 1234567 Corporation) holds an ownership stake in its U.S.-based licensee. Numerous stations in northern New York target larger cities in Ontario and Quebec in addition to their local areas of New York, including (but not limited to)
WYSX targeting
Brockville;
WRCD,
WVLF and
WMWA targeting
Cornwall; and
WQLR and
WBTZ targeting
Montreal. By contrast under
CRTC regulations, Canadian radio stations must be operated from studios within the country. Attempts at border-blasting were somewhat more common on the other side of the border, where smaller markets in the United States could find lucrative larger markets in Canada within their broadcast range.
WIVB-TV, prior to the digital television transition, could be seen as a U.S. border blaster into Canada (as Western New York is a smaller market than
Southern Ontario, which boasts the major world city of
Toronto); it operated with 100,000 watts of power on the VHF low band (channel 4), even after the
Federal Communications Commission reduced the maximum allowed power for that band to 80,000 watts. (WIVB did not make significant attempts to reach the Canadian market, although rival station
WKBW-TV did.) Another famous U.S.-based border blaster into Canada was
KCND-TV in
Pembina, North Dakota; Pembina was a small border town of less than 1,000 residents, which normally would be far too small a market to support a television station, but spent its fifteen-year existence targeting
Winnipeg, a much larger city sixty miles north of Pembina. Likewise, the small market of
Burlington, Vermont, and
Plattsburgh, New York, found it could reach a larger audience in
Montreal. Canadian regulators put in
simultaneous substitution requirements to prevent losing revenue to these American border-blasters (this forced KCND's owners to sell the station to Canadian interests, who transformed the station into modern-day Winnipeg, Manitoba-based
CKND-TV; Burlington station
WFFF-TV entered into a famous cross-border scheduling feud over the simsub problems, while WKBW, after
unsuccessfully suing to bar the CRTC from enforcing it on systems that only operate in one province in 1977, competed mainly by focusing on its unique brand of local news, which could not be simsubbed). Also in Western New York, radio station
WTOR is licensed to the northwesternmost municipality in the region (
Youngstown), operates with a
directional signal covering Southern Ontario but very little American territory, and is brokered to a Canadian ethnic broadcaster based in
Mississauga; it maintains its U.S. license and transmitter site as a
legal fiction, with ethnic broadcaster
Sima Birach holding the station's license and claiming himself as "operations manager" even as he seldom appears at the station's nominal U.S. studio in person. In the west,
KVOS-TV in
Bellingham, Washington, targeted an audience in
Vancouver and
Victoria for many years. In fact, KVOS' inaugural broadcast, in June 1953, was a kinescope film of the
Coronation of Queen Elizabeth II, which was broadcast over KVOS as Vancouver's
CBC Television station,
CBUT, had yet to sign on. At least one border blaster targets the
Russian Far East:
KICY broadcasts its religious programming on a 50,000-watt clear-channel directional signal pointed due west from the
Seward Peninsula, one of the westernmost land masses in North America. ==Programming==
