KDEF-LP (101.5 FM) was a radio station broadcasting a religious format.
Licensed to Adelanto, California, United States, it served the Victor Valley area.
Much of its programming replicated that of KWVE-FM in San Clemente, California.
KDEF-LP ceased operations on August 8, 2017, and surrendered its license to the Federal Communications Commission (FCC) for cancellation the following day.
These actions were taken due to Calvary Chapel of Adelanto's application for a license for its new construction permit, KPTG-LP.
