Note: Coverage Maps are done to the best of my guessing and the best of my ability.. my predictions are that an average Class A station's signal travels about 55 km, and I adjust that according to how high their transmitter is.. an average Class B station's signal travels about 95 km, and I adjust that according to antenna height, and an average Class C station's signal travels about 114 km, and I adjust that.. certainly the coverage maps are generous.. if you want better ones, go here: FCC Coverage Area Database (its much better.. remember I'm not that good at this yet)
