Radio Zodiac was a short-lived station from the Castleknock area of Dublin. They were first noted by the Anoraks UK Weekly Report in August 1984 (where the name was misheard as ‘Radio Maniac’ due to poor modulation) and used a variety of frequencies around the 1400-1530 kHz area of the medium wave band. They were last noted in January 1985 and seemed to have settled around 1410 kHz by then. Radio Zodiac’s transmission times seemed to be irregular and it falls more into the hobby pirate category than a commercial operation. According to on-air announcements a ‘Zodiac Roadshow’ was in existence.
The owner of Zodiac Ciaran Brannelly told us that they started around June 1984 and were based in a concrete shed in a yard on Dunsink Lane. The AM transmitter operated at about 300 watts and the aerial ran up a tall television mast and across the yard. They converted the shed into a studio and by July they had a full schedule of DJs from 8am to 12 midnight and sometimes 24 hours a day. The music format was open so DJs played whatever music they liked. The average age was 15 to 17 and there were about 25 DJs throughout the week. Zodiac had professional voice drops made in the UK and carried a few local ads to cover rent and ESB costs. The core of listeners was based in Castleknock, Blanchardstown and Finglas but they often got calls from further afield.
In October 1984 the AM transmitter was revamped and a small 50-watt on 105 FM was built. By Christmas 1984 most of the original DJs had lost interest as the studio was in a remote location so new people came on board who were more interested in the radio scene at the time. By March 1985 Zodiac began merging with another station Castle K FM which was based in a house in Castleknock. Radio Zodiac closed around April 1985 and moved to another studio and became BFBS as Castle K had also shut. For obvious reasons it was decided that BFBS would stand for ‘Blanchardstown Frequency Broadcasting Service’ rather than British Forces Broadcasting Service, although the jingles were an edited version of the Cyprus branch of the UK armed forces radio station. BFBS had a good signal because it was relayed to a higher site and was estimated to be on 150 watts on 105.1 FM. By early 1986 BFBS had become Caroline 98 on about 500 watts.
This recording was made on the 29th of August 1984 from 1555-1640. The presenters are Brian Jones followed by Mark Wesley who also does news and there are elaborate home-made jingles based on American singer Roberta Kelly’s single ‘Zodiacs’ (1977). There’s some confusion about the frequency: the cassette label gives 1432 kHz, but 1450 is announced on air along with ‘214 kHz medium wave’ which is in fact metres but that would be equivalent to 1400 kHz. In the pre-digital days the listeners weren’t too bothered about such precision! Thanks to Ian Biggar for extra research. The recording is from the Skywaves Tapes Collection. Skywave Radio International was a shortwave station in the 1980s from Baldoyle in northeast Dublin. Radio Zodiac continues online.
