Radio KGBB-FM (Bob FM)

KGBB (103.9 FM, "Bob FM") is a radio station licensed to Edwards, California, broadcasting to the Antelope Valley area on 103.9 MHz FM. The station is owned by Adelman Broadcasting, Inc, and broadcasts an adult hits format under the Bob FM moniker.

103.9 originally signed on as KRAJ, licensed to Johannesburg, California on El Paso Peak with 1500 watts at 27 meters HAAT. KRAJ aired a Hot AC format as 103.9 The Zone in 1991. The callsign and format was moved over to the new signal on El Paso Peak at 100.9 FM in 1999. 103.9 was flipped to a Regional Mexican format as Radio Exitos, under the call letters KEDD.

In 2006, the tower was moved from El Paso Peak to a new location adjacent to 97.7 KTPI-FM. The format was changed to the current Adult Hits Bob FM format shortly thereafter, and the call letters were changed to KGBB.
