It's a case of history repeating as GMG's Smooth Radio is to replace a frequency currently occupied by Jazz FM.
But this time it's on the South Wales and Severn Estuary digital DAB multiplex, as the output of London's 102.2 will commence shortly.
The removal of Jazz FM leaves the station with just four multiplexes, (London, North West England, West Midlands and West Central Scotland) along with Sky, Freesat and Freeview.
When Jazz FM re-launched in October 2008 Guardian Media Group asked Jazz FM if we they help them fill some of their spectrum until they had an alternative service they wished to provide, South Wales and the Severn Estuary being one of those areas.
Jazz FM told us in a statement: "We are of course disappointed for the audience who enjoy listening to Jazz FM on DAB in South Wales and the Severn Estuary but hope they will continue to listen to us on our other broadcast platforms."
GMG Radio originally closed Jazz FM in the North West of England and London to make way for Smooth (FM) in 2004 and 2005 respectively. Jazz FM then became online only, before being bought by its original owner Richard Wheatly who now runs the station on digital platforms.
