History

WEAW

The station began broadcasting in February 1947, and held the call sign WEAW.[1][6] The station was owned by North Shore Broadcasting, and its call sign stood for its president Edward A. Wheeler.[1][6][2][7]

The station broadcast at 104.3 MHz briefly in 1947, before moving to 96.7 MHz later that year.[2] The station's transmitter was located in Evanston and it had an ERP of 665 watts.[2] In 1948, the station's frequency was changed to 105.1 MHz and its ERP was increased to 36,000 watts at a HAAT of 240 feet.[2][1] The call sign officially became WEAW-FM in 1953 when a companion AM station was launched.[2] In 1961, the station's ERP was increased to 180,000 watts.[2] In 1970, the station's transmitter was moved to the top of the new John Hancock Center in Chicago, with its ERP reduced to 6,000 watts.[2]

Among the music heard on WEAW was light music, easy listening, classical music, and show tunes.[8][9][10][11][12][13] The station also carried programs from local schools, community organizations, and Northwestern University.[7] The station also broadcast background music to stores and other businesses, with ads removed for subscribers.[7][8][14][15] By 1964, all of its subscription services had been moved to subcarriers.[16]

From 1947 through the 1960s, WEAW broadcast Northwestern Wildcats football games.[17] It was also the flagship station of the Chicago White Sox radio network in 1971 and 1972.[18]

WOJO

By late 1972, most of the station's programming was in Spanish, and in December 1972, its callsign was changed to WOJO.[2][7]

In 1986, WOJO was sold to Tichenor Media for $1.4 million.[19][20] In 1997, Tichenor Media merged with Heftel Broadcasting to form the Hispanic Broadcasting Corporation, which merged with Univision Communications in 2004.[21]
