Radio reception, that is. If you live in the US, put in your zip code to see what stations you should be receiving.

Enough to kill a normal man.:devil

Anyway to the subject at hand:

I ran several zip codes through the search and it's about 70% accurate. It evidently does not take into consideration local area interference and metropolitan building densities. It seems to be accurate for the area around the farm but it falls apart in the metro Atlanta area.

They must use the Longley-Rice Irregular Terrain Model for the FM stations and the FCC coverage prediction curves and fields measurement data for the medium wave (AM) stations. Those methods work OK in rural areas that are reasonable flat but have problems in urban, mountainous or heavily wooded areas.

Another fault in the program is they appear to be using the studio location not the transmitter location for the basis of the predictions in Atlanta. This of course is an error as the signal originates at the transmitter not the studio.

Yeah, this listing just measures location to location via transmitter strength, e.g. line of sight. Terrain and building construction affects this list on a major level.
