The regional radio station that broadcasts to Wexford, Waterford, Kilkenny, Carlow and South Tipperary is now attracting over 151,000 weekly listeners.
To mark the day, the station will be releasing bunches of red balloons across the South-East.
Latest Joint National Listenership Research (JNLR) figures show that the station has gained 16,000 new listeners over the past 12 months.
It remains the number one choice for adults of all ages in the South-East.
Among the station’s hit radio shows are Beat Breakfast with Niall and Vinny, Beat at Work with Darren Rice and Teresanne O’Reilly, Beat Drive with Andy Mac and the Sunday Grill with Orla Rapple.
The station, that prides itself on doing things a little differently, has won a string of awards.
“We are so lucky to have a hugely talented team who are all passionate about Beat and who are constantly striving to create entertaining, topical radio content,” said Beat 102-103 chief executive and programme controller Gabrielle Cummins. She paid tribute to the station’s loyal listeners and advertisers who had played a leading role in putting the station in the top slot in the South-East region.
The station had a pre-birthday party with the Coronas at the Daytripper Music festival in Waterford, with the band presenting Ms Cummins with a birthday cake on stage.
