As well as being carried on FM in London, 102.2 Smooth Radio is simulcast on several DAB mulitplexes, online and on digital television - Sky, Freeview and Virgin Media.
The station launched on 4 March 1990 as Jazz FM, playing mainly soul and jazz music. It was relaunched in June 2005 as 102.2 Smooth FM, playing middle of the road music, soul and R&B during the day and, as part of its licence requirements, focused on jazz music at night. On October 20, 2006, GMG Radio announced that it was requesting a change of format for 102.2 Smooth FM from Ofcom, moving the station away from its daytime soul and R&B remit which had, until that point, formed an integral part of the licence. GMG proposed an easy listening music service mixed with speech for the over 50's, coupled with an improved local news service. Ofcom approved the changes on December 8th, 2006, with the condition that GMG retained the 45 hours of jazz per week that constituted part of the former licence requirement.
As a result of the format change, GMG have agreed to adhere to a minimum of 20% of its music during daytime being over 40 years old, to distance the station from its London rivals Magic and Heart 106.2.
Paul Chantler has been appointed by GMG to be full-time programme consultant to the station from 14th January 2008 for one year. He will be working with the existing programming team to develop the sound of the station.
In March 2008, GMG requested a format change to remove the 45 hour jazz commitment it has in place for 102.2 Smooth Radio. Part of the plans included a relaunch of Jazz FM from the current jazzfm.com service currently broadcasting on DAB in Glasgow and online on a DAB multiplex in London. In a meeting on April 22, 2008 Ofcom denied GMG's request to drop its jazz commitments. GMG will be relaunching Jazz FM despite the decision.
On October 6, 2008 Smooth Radio was removed from the MXR Wales and West multiplex to allow for the relaunch of Jazz FM. Although initially, Real Radio was removed, Smooth Radio was removed and Real restored on the multiplex.
Smooth's jingle package was produced by Bespoke Music, and voiced by Sean Bolger.
Mark Goodier's Mid Morning Show, Tony Blackburn's Weekend Breakfast Show, Chris Tarrant's Saturday morning show, Andy Peebles' Soul Train and Fiona Phillips' Sunday Afternoon show are simulcast from 102.2 Smooth Radio and can be heard on several other stations in the Smooth Network. All other output is produced locally.
