Premier Christian Radio is appealing to listeners to help raise money to put the station nationwide.
It is though the station will launch on the national Digital One multiplex on September 21st, but has asked listeners to fund the move.
"The only way the £650,000 in transmission costs will be covered is through the generosity of friends like you," Premier chief executive Peter Kerridge wrote in an email to listeners.
He continued: "It is fantastic that God has moved in such an amazing way to provide Premier this national digital licence! Now may you and I be found faithful as we steward this new resource for His glory and for the advancement of His Kingdom!"
The station currently broadcasts on DAB and AM in London, along with Sky Digital channel 0123 and Freeview channel 725.
