Personally, I think the FCC royally shafted stations with this C0 business. Especially the stations that already upgraded to 300+ meters under the 1986 "use it or lose it" rule, so as to maintain their full Class C status. If I remember correctly, 93.7/Ocala was one of these stations.
So, these stations do as the FCC says. They spend the money to construct a 1,000+ foot tower, new transmitter, etc., and upgrade their facilities. Most of the stations in smaller markets really struggled with that decision and the additional expense it created. Then, a few decades later, the FCC comes back and raises the bar again. So now, these same operations are supposed to shell out MORE money for a nearly 1,500 foot tower or face encroachment from new stations on or directly adjacent to their channel? How is THAT fair?
