Kfm use a transmitter based outside their franchise area - on Red Gap in County Dublin - to serve the north of Kildare. Kfm's broadcast area is the most station saturated in the Republic of Ireland, primarily due to the close proximity to Dublin City. A large number of Dublin City based stations as well as two of the "super regional" youth stations can be received in the Kildare area, which impacts heavily on Kfm's listenership and reach.
For the period from 2004 to June 2006, Kfm had the lowest listenership percentage and reach of any station based outside of a city in Ireland, although it finally managed to leave this position in the July 2006 JNLR figures. However, it eventually returned to the bottom. Currently (May 2009 figures), the station has 23% weekday reach (lowest in the country), and 16.5% share (also lowest). 7 day reach figures rise to 48%, second from bottom. The Kfm schedule is as follows, Breakfast - Stephen Keogh, Mornings - Clem Ryan, Lunch - John Dunne and Drive - presented by Paul Power.
