|Absolute has advised listeners to switch to digital platforms|
The AM transmitters at the privately owned Manor Farm site were switched off on Friday, as the lease on the site is not being renewed.
Absolute Radio's transmissions on 1233kHz, which served Berkshire, southeastern Oxfordshire and south west Buckinghamshire were terminated on Friday morning.
Smooth Radio, which inherited the former frequencies of Gold last year has also been affected. Its service on 1431kHz from the site was switched off alongside its service on 1485kHz, which although broadcast from a different site operated under the same commercial AM radio licence serving the Thames Valley area.
Listeners to both stations are being advised to continue listening via digital radio, either via DAB digital radio, online, via mobile apps or through digital TV services.
