On July 4, 1977, the station signed on as KXBQ.[4] It was owned by Ontario Broadcasting Company and aired a contemporary Top 40 format. In 1982, it was acquired by Capps Broadcasting, which also owned AM 1380 KSRV.
Adult contemporary (1987–200?)
In 1987, it switched its call sign to KSRV-FM, airing an adult contemporary format, while the AM station played country music. At the time, KSRV-FM only broadcast at 27,000 watts from a 280 foot tower, so its signal did not reach the larger Boise market. It was later that the power was nearly doubled and the transmitter moved to a much taller tower near Boise, making its signal competitive with other FM stations in the Boise radio market, as a "move-in" station.
Country (200?–2007)
KSRV-FM aired a country music format branded as "The Bull".
Adult hits (2007–present)
On March 30, 2007, the country format was dropped in favor of an adult hits format. Branded as Bob FM, it plays an array of hit artists from the 1980s, 1990s, and 2000s. Boise is one of the rare markets with competing adult hits stations: KJOT airs a similar format, branded "Jack FM".
Bob FM is widely known for its morning show, Rick & Carly in the Morning, which airs weekdays from 6a.m to 10a.m. and Saturdays from 10a.m. to 6p.m.; it is also available as a podcast.
Fox Sports Boise HD2 subchannel
On October 7, 2021, KSRV-FM began HD Radio broadcasting and launched a sports format on its HD2 subchannel and a new translator (K260CU) at 99.9 MHz, branded as "Fox Sports Boise" and airing national Fox Sports Radio programming. This would become Iliad Media Group's eighth station in the Boise metropolitan area. The translator, moved in from Emmett, Idaho, had been stunting with Christmas music and later a loop of "Thriller" by Michael Jackson.[5][6]
