TVN never built the 50 kw site. They forgot to get zoning approval from the township, never got off the ground.
DBN was, as I recall, 80 kw but only 300' AHAAT, it's now WQMX at a more conventional 16 kw @ 880' AHAAT.
Don't recall DOK being that high power. 107.7 Dayton was WDAO, but don't think it was high power, just a good antenna location.
WNOB, like DBN, was something like 88 kw, big multi-bay antenna, but low AHAAT. They were close to 107.3, Elyria, so they were pretty far east of Cleveland.
In Columbus, you had WSNY when it was on a short tower at 70 kw, I believe, they went on the community antenna on the WBNS TV tower. NCI is still 175, on-top of the Nationwide building downtown.
The old WPAY, Portsmouth, was a full class C, 100 KW, with the tower in Kentucky. An ice storm took that tower down, FAA wouldn't let them rebuild, so they dropped to a C0, still 100 KW.
WQXK (once WSOM), Salem, is still 88 kw at 450' ahaat.
