Is KMOS the same as KMOS-TV ?
Found this at
"In 1978, Central Missouri State University, located in Warrensburg, MO, purchased bankrupt CBS-affiliate KMOS, located about 28 miles east in Sedalia. With PTFP assistance the station was put back on the air as a PBS affiliate in 1979. Today, KMOS-TV provides analog PBS service on Channel 6 to more than 800,000 people in 36 central Missouri counties."
