query: When was the TV station KWHB established?
passage: KWHB
After the Rehburg group backed out of the sale, the permit would finally find a buyer who would sign on the station in the fall of 1984, when the permit was sold to San Francisco-based Coit Drapery and Cleaners, Inc. Channel 47, as KTCT, first signed on the air on June 3, 1985. Operating as a religious independent station, it originally maintained studio facilities located at East 58th Street and South Garnett Road in southeastern Tulsa (0.1 miles [0.16km] east of the then-studio facility of KGCT). Its initial schedule consisted of Christian programming from the PTL Satellite Network, including shows such as The PTL Club, Heritage Village USA and 100 Huntley Street, as well as programs from televangelists such as Kenneth Copeland, Jerry Falwell, Jimmy Swaggart and Richard Roberts. KTCT suffered from financial problems early on, and reduced its programming schedule to approximately six hours a day by that winter. Coit Drapery and Cleaners opted to put KTCT up for sale there, and wanted to sell the station to a Christian religious broadcast ministry.
passage: WBPX-TV
The station first signed on the air on January 3, 1979 as WQTV, under the ownership of Arlington Broadcasting. It carried programming from the Financial News Network, along with public domain movies and most network programs that were pre-empted by WBZ-TV (channel 4), WCVB-TV (channel 5) and to a lesser extent WNAC-TV (channel 7; later WNEV-TV; now WHDH). Channel 68 was the first UHF television station to employ what is known as "circular polarization" antenna transmission, which was intended to improve signal reception to inner city viewers, many of whom had difficulty receiving television reception due to surrounding tall structures. The station's transmitter, containing its "helical" broadcast antenna, was installed by helicopter in September 1978 on top of the Prudential Tower.
