its primary purpose was to promote the sale of radio receivers, and KQV remained commercial-free until 1925. On November 11, 1928, a major reallocation resulting from the Federal Radio Commission's General Order 40 assigned KQV to a "regional" frequency, 1380 kHz. In 1932 the station was sold to H. J. Brennan, and the studios moved to the Chamber of Commerce building. On March 29, 1941, under the provisions of the North American Regional Broadcasting Agreement, all the stations on 1380 kHz were shifted to 1410 kHz, which has been KQV's frequency ever since. In 1944, the station was sold to Allegheny Broadcasting. The sale was necessary because both KQV and WJAS were under common ownership, and the FCC no longer permitted multiple AM station ownership within a community. A 1947 station advertisement, promoting its power increase to 5,000 watts, described KQV as "Pittsburgh's Aggressive Station". "The Groovy QV" In 1957, the station was once again sold, this time to American Broadcasting-Paramount Theatres, then the corporate parent of ABC Radio. During the late 1950s, 1960s and 1970s KQV was quite successful as a Top 40 station, with Count John K. Chapel a popular radio personality during most of this period. Known over the years as "Colorful KQV," "Audio 14," "Groovy QV," and "The Big 14," KQV debuted its Top 40 format on January 13, 1958, and is remembered for its high-profile, high-energy personalities, such as Robert Wolfson a.k.a. Bob Wilson, Chuck Brinkman, Hal Murray, Dave Scott, Steve Rizen, Dex Allen, Jim Quinn, future game show announcer Rod Roddy, and their large-scale promotion of a Beatles concert at Pittsburgh's Civic Arena in 1964. During this time, KQV broadcast from its showcase studios on the ground floor of the Chamber of Commerce Building ("on the corner of Walk and Don't Walk," as the DJs would say) in downtown Pittsburgh, where the disk jockeys could be watched through a large window. The station was dominant among young listeners throughout the 1960s, and was a major force introducing Pittsburgh to new music and artists such as Sonny & Cher, the Rolling Stones, the Supremes, the Beach Boys, the Dave Clark Five and others. KQV ratings began to slowly decline after 1970, with the advent of competition from WJAS and the rise of FM radio (including its then-sister station 102.5 WDVE, which had begun operation in 1948 as KQV-FM).
