WDER (1320 AM) and WDER-FM (92.1 FM) are radio stations broadcasting a Christian radio format. They are the flagship stations of the "Life Changing Radio" network. WDER AM is licensed to Derry, New Hampshire, and WDER-FM is licensed to Peterborough, New Hampshire. The stations are owned by Blount Communications, Inc. of NH and feature programming from Salem Radio Network.[5][6]
In 2012, Blount Communications purchased 92.1 FM, then WFEX, from Phoenix Media/Communications Group, and changed the call letters to WDER-FM, providing WDER AM with a sister station on the FM band to extend its outreach. Prior to the purchase, WFEX had served as a simulcast of WFNX (now WBWL) in Boston.[7]
