Again this post is going to be about something that you might use everyday, though it is being used less and less now, but might not know much about it.  It's a radio.  They used to be much more prevalent before tv got popular, then they got relegated to the car, but now with mp3 players and satellite radio they are rarely used.

I found this page on the FCC website while doing research about radio broadcast stations nearby.  I thought it was pretty interesting that you can see so much information about what is around.  These are FM stations within a 50km radius of New Paltz.  The labels for the columns seem to be off a little, but the numbers are pretty self-explanatory.  The column with the kW next to it is the power radiated by the station, the higher the number, the better signal you would receive.  The third column from the right is the distance from the point you entered to the station, again the smaller the number, generally the better the signal.

One of the numbers I didn't even expect to see would be the HAAT or Height Above Average Terrain, which essentially is how high up the tower is off the ground.  The higher the number, the less things that will be in your way, so it should result in a better signal.

They also have ones for Am radio and digital TV which you may also be interested in checking out.

Anyway, that was just a little site that I found that may be interesting or helpful to some people.

Note: If you do decide to use the search, it will probably be best to go to the bottom and use the latitude and longitude (you can google where the lat/long of where you are, use this to convert it to DMS) as well as radius size and leave everything else blank.  Also there is a selection box for the output, I think Query is the best option to choose because it seems to be the easiest to read.
