Pulse 1 and Pulse 2 opened its doors to listeners on its 40th anniversary of broadcasting to Bradford and West Yorkshire.
The UTV stations invited people to join them during the day for birthday cake and a cuppa, a tour of the new studios and a chance to meet some of the presenters.
The station also played clips of the last 40 years on-air during the day, highlighting the history of the station which started on September 16th 1975.

Pulse 1 launched as Pennine Radio 235 and was later rebranded to Pennine FM and then in 1991, The Pulse/Pulse FM. More recently it changed to its current name to match its sister station, Pulse 2.
