Until 1976, KTVO, licensed to Kirksville, Mo., had most of its local programming originating from its studio in Ottumwa, Iowa, shared with co-owned KBIZ radio. The network feed - first CBS, then ABC - came from Des Moines via Ottumwa via a Northwestern Bell relay. There was still a studio at the Missouri transmitter site near Lancaster. Newscasts often originated from both states. When color cameras came along circa 1968, there was one color camera at the Ottumwa studios and one at the Lancaster site. The color film chain was in Ottumwa as were the videotape machines. In 1976, KTVO moved all studios to its present location just north of Kirksville. I've never been able to find evidence to back up the rumors I heard that the FCC caught on to the dual-studio operation and made noises about not getting a main studio waiver to reflect the predominance of the Ottumwa studios in the station's operations. One ironic note is that, since the 1976 move, the Kirksville economy (and population) has grown slowly due to the presence of a state university and a college of osteopathic medicine while the Ottumwa economy and population have declined due to the loss of several major industries.
