I believe the TX was at St Marys (in the Dunheaved industrial estate next to the Golf Course) when Radio 2 first started.
They had a sales office in Blacktown, but the studio was in Crows Nest - it was often a joke amongst announcers that they couldn’t pick up the station at the studio.
With the site at Badgery’s Creek - I believe Cool Country Radio on 1476 used that site at the cnr Elizabeth Dr and Luddenham Rd until they disappeared 10 years agoi.
107.9 has been open carrier for the past two weeks now. Seems like this isn’t the first time they’ve just left their TX on for an extended period of time after their licence expired.
