On December 9, 1933, the station signed on as WMBR, at 1270 kilocycles. It was owned by the Florida Broadcasting Company and was powered at only 100 watts. In the 1940s, WMBR moved first to 1400 khz, powered at 250 watts. Then it switched to 1460 kHz and increased its power to 5,000 watts. WMBR was a CBS Radio Network affiliate and carried its schedule of dramas, comedies, news, sports, soap operas, game shows and big band broadcasts during the Golden Age of Radio. In 1948, it added an FM station, 96.1 WMBR-FM, and in 1949, it put a TV station on the air, Channel 4 WMBR-TV. WMBR-TV was the first TV station in Jacksonville and carried programming from all the major networks initially. Meanwhile, in 1942, another AM station went on the air in Jacksonville, WJDC at 1270 kHz. It was owned by the Jacksonville Broadcasting Company and was powered at 5,000 watts. In a few years, it had moved to 600 kHz. It changed its call sign to WPDQ and was an ABC affiliate. Henderson Belk, a North Carolina businessman, purchased WPDQ in 1964 from Brush-Moore Newspapers,
Moving to AM 600
In the 1960s and early 1970s, WPDQ carried a Top 40 format, while WMBR stayed with its full servicemiddle of the road format. In 1975, after Belk sold the station to Robert Rounsaville of Atlanta, the two stations made a switch. WMBR took the better frequency at 600 kHz, describing its format as "Bright MOR Personality." WPDQ moved higher up the dial to WMBR's old frequency, 1460 kHz, continuing its Top 40 sound. In 1977, AM 600 switched its call letters to WSNY, calling itself "Sunny 60," although the format remained Bright MOR Personality. Then in 1980, the call letters were changed to WAIV. AM 600 began simulcasting Top 40 programming from its FM sister station 96.9 WAIV-FM, known as The Big Wave.
From Country to Talk
became the new format in 1981 with a call letter change to WOKV, known as "OK 60 The Unrock." Music continued on WOKV with various adjustments from pop country to adult contemporary to oldies. Then in the 1986, the station was bought by EZ Communications. AM 600 became WOKV, featuring a news/talk format, and was Jacksonville's original home of the syndicatedRush Limbaugh Show. In 1994, Prism Radio Partners acquired the former WAPE/690, "The Big Ape." WAPE had Jacksonville's best AM signal, powered at 50,000 watts by day non-directional, 10,000 watts at night with a directional signal. The WOKV callsign and news/talk programming was moved to 690 AM. The WPDQ callsign was again returned to AM 600 with an adult standards format.
Sports and Children's Programming
In 1996, Prism changed the AM 600 call letters again, this time to WBWL. The station became known as "The Ball" with a format change to sports radio. Cox Radio purchased the station in 1999, and in 2001, AM 600 "The Ball" was sold to The Walt Disney Company with a format change to Radio Disney programming.
WBOB Talk
programming lasted until December 2010 when Radio Disney sold WBWL to Chesapeake-Portsmouth Broadcasting Corporation. The call letters were changed to WBOB with a conservative talk format. It featured Bill Bennett's Morning in America, Laura Ingraham and Glenn Beck along with a variety of local news and talk programming. As of the 2014 season, WBOB broadcasts games from the Jacksonville SharksArena Football League. Also in the mid-2010s, WBOB got a power boost, going from 5,000 watts day and night, to 50,000 watts in the daytime and 9,700 watts at night.
