94.9 FM began as KLRO-FM in 1960 with a middle-of-the-road format. On September 14, 1978, KLRO-FM flipped to gold-based adult contemporary, changed call letters to KBZT and changed monikers to "K-Best 95." In the mid-1980s, the station flipped to oldies. In 1987, after the station was sold to Sandusky Radio, the station adopted new call letters KWLT, flipped to soft rock, and changed monikers to "K-Lite 95", before changing again to "Y95" and the KKYY calls in 1989. As KWLT, the station launched the local careers of morning show hosts, Jeff Elliot and Jerry St. James, better known as Jeff and Jer. In 1991, Jeff and Jer moved to rival B100, with KKYY changing its name to "Mix 94.9", adopted new call letters KRMX, and added more gold based music, before reverting to back to oldies, again as "K-Best 95" on January 16, 1992, though with the call letters KBZS. In the mid-1990s, Sandusky sold the station to Anaheim Broadcasting, which in turn sold 94.9 to Jefferson-Pilot, making KBZT a sister station to country-formattedKSON-FM. On November 10, 2000, due to low ratings, KBZT switched to an "'80s Hits" format, just a day before KMSX dropped hot AC and adopted the same format. On November 11, 2002, KBZT flipped to alternative rock, branded as "FM 94/9". In 2006, Lincoln Financial Media bought KBZT and all the others that were owned by J-P, including KIFM and KSON. On December 8, 2014, Entercom announced that it was purchasing Lincoln Financial Group's entire 15-station lineup in a $106.5 million deal, and would operate the outlets under an LMA deal until the sale was approved by the FCC. The sale to Entercom was consummated on July 17, 2015. On February 1, 2018, KBZT rebranded as "Alt 94.9", aligning itself with Entercom's similarly branded stations across the country. The rebranding also solidified its continued operation as a music station; Entercom's hiring of former XEPRS jock Dan Sileo led to speculation that either KBZT or KEGY would be flipped to a sports talk format to accompany Sileo, as well as Entercom's rights to the San Diego Padres. The team announced later that month that Padres broadcasts would move to KEGY, which flipped from Top 40/CHR to the hot talk-driven The Machine on March 2, 2018.
Past programming
As of October 2007, FM 94/9 was one of at least five stations in the San Diego market at the time playing modern rock music. However, on its website, FM 94/9 purports to strive to be different from other radio stations by playing diverse music, broadcasting locally produced music and using a live and local airstaff. Shows on the station include:
The Local 94/9 – Hosted by local artists TJ, "Poor Pat", and Dan Brozo
In April 2006, the Lincoln Financial Group completed a merger between themselves and the Jefferson-Pilot Corporation. The media assets of the new merged company are now called . During the October 2007 wildfires in the San Diego area, KBZT became the temporary home of local public radio stationKPBS-FM 89.5 after power to the KPBS-FM/TV transmitter on Mount San Miguel was interrupted on the morning of October 23. Within three hours KBZT had agreed to air KPBS' wildfire coverage until a backup transmitter could be established from the station's studio tower on the San Diego State University campus, which occurred the next day. In January 2010, "The Mikey Show" moved from KIOZ to KBZT. This program had been controversial while in syndication and was taken off air in March 2012 as a result. In June 2012, "Brunch with Bob and Friends" ended an eight-year run at the station, moving to KOPA Rez Rado 91.3. On October 19, 2015, Chris Cantore became co-host of the morning show with Steve Woods. Cantore had previously hosted mornings at KPRI but lost his job in September 2015 when that station became part of the contemporary Christian K-Love network. Cantore left in early 2017, and later joined KFMB-FM; the morning slot was replaced with Dana and Jayson. Dana and Jayson, in turn, left KBZT on January 22, 2020, due to budget cuts at Entercom. Both personalities had made the transcontinental move from upstate New York to host the morning drove program at KBZT.
HD Radio
KBZT carries its alternative rock format on the standard analog and HD1 channels. On their HD2 sub-channel, KBZT carries a reggae format as "Bob Radio", which is named after Bob Marley. On September 17, 2014, KBZT launched a Dance/EDM format, branded as "Glow", on its HD3 sub-channel. The station stream is also available online as well.
