WWSW-FM
WWSW-FM (94.5 MHz) – branded 94.5 3WS – is a commercial radio station that is located in Pittsburgh, Pennsylvania. It airs a classic hits radio format and switches to all–Christmas music for most of November and December each year.
This station is owned by iHeartMedia, Inc. Its studios and offices are located on Abele Rd. in Bridgeville next to I-79, along with its sister stations. The transmitter is situated off Rising Main Avenue at Lanark Street, on a tower that is shared with WPXI-TV and other FM stations in the Pittsburgh radio market. WWSW-FM broadcasts using HD Radio technology, with its third digital subchannel airing Catholic radio programming from Relevant Radio.
WWSW is notable for being an FM "superpower station". Its effective radiated power (ERP) is 50,000 watts on a tower that is 247 meters (810 ft) tall. The standard height above average terrain (HAAT) for Class B FM signals found in Pennsylvania is 152 meters (500 ft) for a station broadcasting at 50,000 watts.
On August 13, 1940, Walker & Downing Radio Corporation applied to the Federal Communications Commission (FCC) for a construction permit to build a new FM station. It broadcast on 43.5 MHz in the original FM broadcast band, which was located between 42 and 50 MHz. The FCC granted the permit on December 12, 1940, while reallocating the station to 44.7 MHz and assigning the station the call sign W47P. The station was granted its first license by the FCC on May 20, 1942. On September 23, 1942, the FCC modified the station's license when Walker & Downing Radio Corporation changed its name to WWSW, Inc., named after co-owned WWSW (970 AM).
On November 1, 1943, the station was assigned the WTNT call sign, followed by another call sign change to WMOT effective October 3, 1945.
The FCC created the current FM broadcast band on June 27, 1945. The commission granted WWSW, Inc. the authority to cease operations effective December 12, 1945, so the station could be converted to a new frequency on the new band.
On July 25, 1946, the FCC reallocated the station to 94.5 MHz, and granted WWSW, Inc. a construction permit for operation on the new frequency effective November 13, 1947. On February 24, 1949, the call sign was changed to WWSW-FM. Following a series of modifications to the construction permit from 1947 to 1954, the FCC granted the station a new license with the new facilities on January 11, 1954.
The station's license was voluntarily reassigned to WWSW Radio, Inc. effective August 1, 1955. On December 21, 1957, the FCC granted the new owner a construction permit to increase the station's effective radiated power (ERP) to 50,000 watts while increasing the antenna height above average terrain (HAAT) to 940 feet. A new license with the upgraded facilities was granted by the FCC on September 25, 1958.
