before finally obtaining ABC affiliation in January 1967. Programs were received by off-air pickup and by a private microwave link that fed ABC affiliate WSIX-TV in Nashville to new studios in the former National Guard armory in downtown Bowling Green. 1969 tower dynamiting incident At 2 a.m. on September 26, 1969, residents throughout Bowling Green and surrounding Warren County heard a blast. When the sun came up, the transmitter engineer saw that the WLTV tower was leaning 15 degrees, having bowed in the middle, after an estimated 48 sticks of dynamite were set off at the base of the station's mast. Windows shook at the transmitter building, where debris from the explosion punctured holes in the roof, and in two surrounding homes; as the engineer had already left for the night, there were no injuries. The investigation centered on one possible reason. WLTV had in recent months become known for editorials on crime in the Bowling Green area. However, there was little information for an investigation to go on. A grand jury was convened in October, to which WLTV's news director testified, but no charges resulted; much of the evidence was destroyed by the blast itself. Meanwhile, efforts immediately began to restore service from WLTV. With the microwave link to the Armory studios severed, equipment was carted back up to the transmitter site to permit limited local broadcasts, and a makeshift antenna out of chicken wire was tested. The damaged mast was purposely brought down October 1, permitting workers to begin erecting a temporary tower; an antenna was shipped by air freight from California. From these facilities, WLTV returned to the air on October 6. WBKO In February 1970, Argus reached a deal to sell WLTV to Professional Telecasting Systems, Inc., a subsidiary of the Lincoln International Corporation of Louisville. Professional Telecasting immediately promised to complete the task of rebuilding the station to provide full-power service again and to begin color broadcasts; at the time, the only color programs seen on WLTV were rebroadcast from ABC. The $1 million transaction was approved by the FCC in June. Professional Telecasting opted to rebuild WLTV's transmission facility at a site to the north of Bowling Green, near Richardsville, instead of to the south. This was because many Bowling Green TV antennas were pointed south to receive Nashville stations. In order to complement the technical overhaul, the owners also filed to change the
