WLTJ
WLTJ (92.9 FM, "Q92.9") is a commercial radio station in Pittsburgh, Pennsylvania. It is owned by the Frischling family through licensee WPNT Media Subsidiary, LLC, and broadcasts a hot adult contemporary radio format.
The station's studios are located in Pittsburgh's North Hills suburbs at 5000 McKnight Road, and its transmitter is located in the Summer Hill neighborhood of Pittsburgh. The tower is co-located with WPGH-TV and WPNT.
WLTJ is a grandfathered "superpower" station. While the station's effective radiated power (ERP) is within the maximum limit allowed for a Class B FM station, its antenna height above average terrain (HAAT) is too tall for its ERP according to current FCC rules.
WLTJ broadcasts using HD Radio technology. It offers three additional digital subchannels as well as its main analogue programming.
On November 19, 1940, Westinghouse Radio Stations, Inc. applied to the Federal Communications Commission (FCC) for a construction permit. It wanted to build a new FM station on 47.5 MHz on the original 42-50 MHz FM broadcast band. The FCC granted the application on January 14, 1941, by which time the commission had assigned the W75P call sign to the station. The FCC then granted permission to begin broadcasting at any time beginning on April 4, 1942, followed by the station's first license on March 2, 1943.
On November 1, 1943, the station was assigned the KDKA-FM call sign. After the FCC created the current FM broadcast band on June 27, 1945, the commission granted Westinghouse Radio Stations the authority to begin operating the station on 94.1 MHz on March 19, 1946. The FCC reassigned the station to 92.9 MHz on April 8, 1946, while allowing continued operation on 94.1 MHz . On July 26, 1946, the FCC granted a license renewal for operation on both 47.5 MHz and 92.9 MHz . Subsequent renewals for operation on both frequencies would later be granted on June 1, 1947, and June 1, 1948, ending on March 1, 1949. The FCC granted Westinghouse Radio Stations a construction permit on January 23, 1947, to build new facilities for operation on 92.9 MHz, including installation of a new transmitter and antenna at a new site. The FCC granted a new license with the new facilities on June 26, 1952.
In the late 1950s, several systems to add stereo to FM radio were considered by the FCC. Included were systems from 14 competitors, such as Crosby, Halstead, EMI, Zenith Electronics Corporation and General Electric. The individual systems were evaluated for their strengths and weaknesses during field tests in Uniontown, Pennsylvania, using KDKA-FM as the originating station. The FCC granted permission on December 4, 1958, to begin these experimental broadcasts between midnight and noon on a non-commercial basis using the KG2XIK call sign. On July 1, 1960, the FCC changed the experimental call sign to KG2XIU while extending experimental broadcast authority to September 4, 1960. While credit is given for WEFM Chicago and WGFM Schenectady, New York on June 1, 1961, as the first stereo FM broadcasters, KDKA-FM was the first to broadcast in stereo, albeit on an experimental basis.
During the 1970s, KDKA-FM was an automated station that played beautiful music during the day, and classical music at night. During morning and afternoon drive time, the station simulcast sister station KDKA 1020 AM, so both stations could offer up to the minute news, traffic and weather.
