AM 850 was a 50kw 3 tower directional station licensed to Knoxville. It was the original WIVK-AM first @ 860 then to 850 and the power increase. It was donated to the University of Tenn. (not sure of the year) then sold to J. Bazel Mull as the AM to WJBZ-FM. Horne Properties purchased it and tried several formats then turned it off. Blount Broadcasting bought it and leased the tower site from Horne, when the lease ran out it went dark for almost a year until getting back on the air on the WGAP tower.
WGAP has always been a Maryville station and done well and they got an FM @ 95.7 and it was WGAP AM/FM. The FM was sold off and Horne Properties bought the AM. It was sold about 8 years ago to Ron Meredith and he simulcast WYSH on it until Blount Broadcasting bought it about a year or so ago. If they could pick up a translator for it and AM 850 I think it could do well in the Maryville/Alcoa market.
WLOD, I don't see how this station has stayed on the air since it went on back in the 80's. It had an FM @ 99.1 but it was sold off years ago. I am surprised that it hasn't gone dark but with a translator it might do OK in the Loudon area. There are a couple of LPFM's in Loudon County and they are running local sports so it may be hard for it to find a niche in the advertising money.
I am sure there are more qualified people than myself that could go deeper into the history of the stations .
