Radio kmfm Extra

KMFM Extra is a DAB radio station broadcasting to the county of Kent, South East England. It is part of the KMFM group of radio stations in the county, which are part of the KM Group.

The station was launched as km-d on May 1, 2004. Due to the fact that the NOW Kent multiplex was county-wide, the then 5 local kmfm stations were unable to be broadcast on DAB. The KM Group launched km-d as a county-wide service instead. One year later the name was changed to KMFM Digital, to incorporate the KMFM name into the station.

It relaunched in 2008 with the current name and a new slogan, "Fresh Hits for Kent"; changing from adult contemporary to pop music.

In 2010 the station's schedule was overhauled. The station promised to update its playlist "as and when new tracks drop from the labels", in order to bring new music to Kent, and the introduction of presenter shows including links with universities and colleges in the county. The first presenter-based shows were launched in January 2011, along with a new logo for the station.
