The History of WKBO . . . the beginning
WKBO was the first station to sign on in Harrisburg circa 1923 with the call letters WABB and was owned by Dr. John B. Lawrence. The station was owned by a number of different people in the early years. In 1924, Harrisburg Sporting Goods owned the station. In 1930, the station was owned by Norman R. Hoffman and the call letters were WCOD. And in 1931, the station was purchased by Keystone Broadcasting Organization. Sometime by 1934, the call letters were changed to from WCOD to WKBO (for Keystone Broadcasting Organization). The call letters WKBO had originally been assigned to a station in Elizabeth, New Jersey. Steinman Broadcasting acquired the station sometime in the late 1930s. Steinman also owned WGAL AM-FM-TV, Lancaster (now 1490 WLPA and 101.3 WROZ) as well as WORK, YORK (now 1350 WOYK). Steinman also owned the Intelligencer Journal Newspaper in Lancaster. All of the broadcast properties were eventually sold except for Delmarva Broadcasting consisting of WDEL and WILM. Also, in the 1930s, the station moved its facilities to 31 North Second Street in Harrisburg in a building that still exists today.
Call Letters & Frequency: 
  The call letters: WABB ---> WCOD ---> WKBO
  The frequency: WKBO was not always at 1230.
Originally WKBO was located at 1130. In 1930, WKBO moved down to 1200. In 1941, the North American Regional Broadcast Agreement rearranged the radio dial, and on March 29, 1941, 802 of 893 AM stations shifted frequency. WKBO moved to it's new home at 1230 am.
WKBO was the first of the Steinman stations to be sold. In 1971,  Hurrea Broadcasting, with Michael Rea as principal and J. Albert Dame as  25 per cent owner, acquired the station. Steinman, however, was not known for lavish spending and WKBO had not performed very well over the years. It certainly was not without notoriety, as it broadcast live Wilt Chamberlain’s record breaking 100 point game at Hershey Sports Arena in 1962. With more on the pre- Hurrea era, here’s John Summers who worked at WKBO from 1971-73:
“WKBO had a non-descript middle-of-the-road format of the Englebert Humperdinck/Tom Jones variety.  NBC News on the hour.  NBC Monitor, a music-and-personality service used by many small NBC stations, ran all weekend.  Not a bad station, really, just no real need for it.  A typical low-budget Steinman operation, almost totally dependent on downtown advertisers, who were closing-up fast by 1970.  Good personalities, Charlie Adams and Gary Brooks among them.”
”The old WKBO was not without merit, however.  When hearings were held into Harrisburg’s racial disturbances of the late 1960s, WKBO carried them gavel-to-gavel, the only Harrisburg station to do so.  They allowed Toby Young to do a “soul” show from 6-9pm weeknights, and for a while in the summer of 1970 there was a guy who did a sort-of progressive rock show from 9 pm - 1 am.  They also had a talk show, “Voice of the People,” which aired mornings from 9 til 10.  The host was a guy named Joe Thomas, a real rabble-rouser and very entertaining.”

In 1971, WKBO was in a bad way. It was generally 4th in a then 4-station market (FM hadn’t really begun to develop yet). It’s 1930s era equipment, including the 1938 Western Electric Board, was showing its age. The transmitter and tower were located on top of the Old Penn Harris Hotel (now where Strawberry Square is located). The ground system wasn’t maintained and hence, WKBO’s class IV 1,000 watt day/250 watt night signal was the worst in Harrisburg.

Hurrea Broadcasting had a lot to gain and little to lose.
