Question by John Riordon: What would the range of a 250 watt FM radio transmitter be?
There is a community radio station being built, based on a hill of about 60 feet tall. I want to know how close I have to be to recieve a low watt (250) liscensed FM signal.

Answer by randy
fm signals of that frequency range will only propagate to just barely over the horizon so the higher the antenna the farther the horizon is. There is one condition called tropospheric ducting when i high pressure system is overhead and the signal can ride along the temperature inversion layer for distances around 1000 miles.
