KYFJ is a radio station serving the Lafayette, Louisiana area. The station broadcasts at 93.7 MHz with 100 kW and is licensed to New Iberia, Louisiana. KYFJ is currently under ownership of Bible Broadcasting Network. It was previously held by The Last Bastion Station Trust, LLC, who picked up this station after its previous owner Citadel Broadcasting swapped the station for KNEK-FM.
KRDJ signed on in June 1992 as KKZN, an affiliate of the Z-Rock satellite network. KKZN was a Cavaness Broadcasting station, co-owned with what was then KVOL and KVOL-FM as the first FM duopoly in the Lafayette market; Z-Rock 93.7 was effectively the replacement of the rock format previously heard on KVOL-FM before that station flipped to Urban AC in July 1992. At the time, KKZN was broadcasting with 34 kilowatts from a tower located off Highway 90 in southern Iberia Parish between the towns of Jeanerette and Glencoe.
The rock format lasted only until November, when KKZN became KDEA, picking up the calls dropped in favor of KXKC by another New Iberia station earlier in the year. KDEA switched to hot adult contemporary as KD93.7 shortly afterward.
