The Supergold service was launched at 10am on Sunday 24 June 1990, following requests from the Radio Authority for radio stations to split frequencies into separate AM and FM services or lose them. The first presenters heard were Tony Lloyd and Colin Wiltshire.
Elsewhere, Coast AM, Invicta FM's medium wave AOR/soft rock station, was renamed Coast Classics and began playing more 'oldies'. By 1990 it became a fully fledged 'Golden Oldies' station and in 1991 it started taking the SuperGold service on its 1242 kHz and 603 kHz AM frequencies. As a result, the station was renamed Invicta Supergold. However, just before this change took place, and for most of Summer 1991, presenters referred to the station Coast Classics Invicta Supergold on air, to allow listeners to get used to the change. It achieved a 17% reach in a JICRAR survey; some say much to the disgust of its Southern Radio Group bosses who, it has been said, preferred their AM stations to hover around the 9% mark!
The original weekday presenters included Colin Wilsher for breakfast, Bill Overton with an hour's phone-in at 10.00am, Dave Foster till 3.00 p.m., and Tony Lloyd at Drive, until 7.00 p.m. Sunday programming included Paul Burrell and the Elvis Hour with Willie Morgan who later went on to host the 'Sunday Will Never Be The Same' in early 1991.
The Supergold network closed on Sunday 1 September 1996 following the takeover of Chiltern Radio in 1995 by the GWR group. In place of Supergold, listeners would now receive Classic Gold. The takeover also enabled GWR to base Classic Gold at Chiltern's HQ in Dunstable, where Chiltern's own Supergold service had previously been based.
