Global Radio has turned off the medium wave transmitter for Gold in Crawley and handed back the licence to Ofcom.
The 1521 AM frequency, previously home to Radio Mercury and County Sound, had 11,000 listeners according to the latest available RAJAR results.
It is not known why Global Radio has given up the transmitter, which broadcast a networked Gold feed from London. Cessation of the service was confirmed with a message on its [link=http://www.mygoldmusic.co.uk/Article.asp?id=486495&spid=18956]website[/link]: "From 1st February 2011 you will need to retune your radio to 1548 AM or 1323 AM to continue to hear The Greatest Hits of all Time on Gold."
1548 is the main London transmitter and 1323 being Gold Sussex.
Ofcom, in its monthly broadcast update, confirmed the news but didn't specify why. RadioToday.co.uk is currently waiting for a comment from the press office.
In August 2008, previous owners GCap Media had to close the AM transmitters of (Classic) Gold in Exeter and Torbay to comply with Ofcom ownership regulations.
