Prior to Nova's arrival, Irish radio consisted of the government broadcaster RTÉ and a number of local AM pirate stations. Radio Nova was the first station in Ireland to use a high-powered signal on FM. By 1982 Radio Nova was pulling in over 40% of the available audience around Dublin. In September 1982, Radio Nova (operating on 88.1FM and 819AM at the time) introduced a new service called Kiss FM on 102.7 MHz - inspired by Los Angeles-based 102.7 KIIS-FM.

Prior to May 1983, the stations had been allowed to operate without interference from the Irish government. However, on 18 May 1983, officials from the Department of Posts and Telegraphs together with Irish Gardaí raided both the studio site and the transmitter sites of Radio Nova and Kiss FM. Both stations went off the air until the next day. Following the raids, the Minister for Communications claimed in the Dáil (25 May 1983) that intermodulation products resulting from co-located transmitters for Radio Nova and its sister station Kiss FM had caused interference to emergency services' frequencies around 74 MHz for a period in the previous month.

On 19 May at 6.00 a.m., Radio Nova returned to the air to announce that they would be closing down at 6.00 p.m. that day. They urged listeners to protest against the government and to show up at the Nova studios in Herbert Street, Dublin 2 for a huge protest. The story was on the front page of every national newspaper and was headline news on RTÉ. The hysteria continued when a rival pirate Sunshine Radio was raided at 9.00 a.m. By 6.00 p.m., there were several thousand people outside the studios of Nova as the station played its last record.

The political fallout of the Nova closedown was huge. More protest marches continued and following criticism of the government's action by the judge in the State's case against Nova, the station returned to glory some days later.

During the winter months of 1983, Radio Nova started test transmissions on UHF TV. The station was to be "Nova TV" and was to run a similar format to MTV in the United States. Tests stopped after the government raided the studios and warned they would not tolerate a pirate television station operating.

More trouble was to hit Radio Nova in 1984. The state broadcaster RTÉ which had seen its audience dwindle due to the arrival of Nova and other large pirate stations started a jamming campaign against Radio Nova. The jamming continued for some weeks and made the reception of Nova almost impossible at times. The station eventually went into receivership and shut down its Kiss FM operation. Eventually, the Irish government ordered RTÉ to stop the jamming and once again Radio Nova flourished.

By the middle of 1985, the radio dial in Dublin was getting very crowded. Although the station remained firmly at number one (some survey books during this time show Nova at 62% reach in Dublin), they faced increasing competition from RTÉ and other pirates like Sunshine Radio. There was now also Q102, a station founded by former Radio Nova DJ Lawrence John, after being pressured not to cross the NUJ picket line at Radio Nova. To try to increase revenue, Radio Nova launched a new station called Magic 103. Magic 103 was an easy listening station with a lot of local news and current affairs designed to appeal to the Irish government who were taking part in a national debate about local radio, similar to National Public Radio in the United States. Magic 103 was not a success, however, and was shut down by Chris Cary at very short notice. This infuriated the National Union of Journalists who called a strike and placed pickets on Radio Nova. They also urged advertising agencies to boycott the station. With advertising revenue down dramatically and trouble in the boardroom, Cary pulled the plug on Radio Nova with just three hours’ notice on 19 March 1986.

Subsequently, another station began broadcasting using most of Nova's old equipment and frequencies under the cover name of Zoom 103, later rebranded as ENeRGy 103, NRG 103 stood for "Nova re-generated". However, despite various name changes (Energy Power 103 FM, a "merger" with Radio Nova (The Hot 100 FM), then a re-launch station called Nova Power 103 FM, and once again reverting to the "Energy Power 103 FM" name) this station never enjoyed the same success as its predecessor and was eventually bought out and shut down on 11 March 1988 by rival station Q102. Within two weeks, Q relaunched themselves as "Super-Q102" on NRG's four FM frequencies ranging from 99.9 to 103.1 MHz which effectively "boxed in" Sunshine 101.

Chris Cary subsequently launched a satellite radio station, called “Radio Nova International”, from a studio on the Albany Park Industrial Estate, Frimley, in the United Kingdom. The station was used as an overnight sustaining service by a number of UK and European radio stations.^[1]
