There are a few different sites online that allow you to view the areal coverage of a particular FM radio station (http://www.fcc.gov/encyclopedia/fm-query-broadcast-station-search and http://radio-locator.com/cgi-bin/page?p=maps come to mind). I'm trying to figure out if there are any sites that would simultaneously show this coverage across the entire United States, possibly in a Google Map format. For example, if I picked a frequency (101.1), I could see the approximate coverage of every station with that frequency, where they're located, the call sign, etc. I certainly don't care enough to figure out how to make such a map, but if it already existed, that would be great to see.

I know we have a few radio people on TWW, so didn't know if any of you would have the inside scoop. Thanks in advance!

Here's something, but it doesn't list every station, and isn't a Google map.

There's probably better out there, but this is what a quick search turned up...

Oddly there is no sports radio in Greensboro. >.<

Here's another interesting site... http://www.fccinfo.com/fccinfo_google_earth.php
Use their plugin on Google Earth to find/list registered and licensed transmitters and their info.

How about you come back and let me know if any of this has been helpful

Some of the sites have some promise, but are mainly focused on showing all locations that a single station reaches, or showing all stations that are available at a single location. I've been trying to find something that shows ALL locations for ALL stations. It just may not exist. I appreciate the links that you have posted.

Can you tell us a little bit about what this is for? I'd like to help (and have some ideas), but my level of effort depends on what it's for.

Feel free to PM if you'd prefer.

This isn't something that people should feel the need to invest much time in. Here are the 2 things I was going to use it for.

#1 - I've been traveling different places where I liked a particular station, but I never heard them announce their call sign (I must have missed the hourly announcements). With this, I could simply look on a map wherever I was, find the frequency (ex. 99.9), and figure out what station it is. Sometimes you can Google this (99.9, southeastern North Carolina), but it's not foolproof.

#2 - I have XM radio, and when I'm traveling, it can be nice to know ahead of time what the best frequencies are to set my FM transmitter to (don't have a direct audio jack in my car). Some sites will let you list a location and they'll tell you what the unused frequencies are, but I've found those lists to be pretty unreliable. If I had a map of where the different coverage zones are, particularly at the bottom of the spectrum, I could figure it out myself.

I figured some people may know of this type of site off-hand. It's not something terribly important, so I wouldn't want to ask people to spend their own time researching the topic. But I do truly appreciate the links that people have posted!

give me a few days

An AM radio map would be CRAZY.

You could data-mine this site and plot it on a map.

It doesn't include skywave though.

It's closer to a fortnight than a few days...

Here you go:

I have a pretty weak hosting plan, so it may be slow and will probably fail on large data sets (e.g., the whole country).

^That's pretty awesome, man! Nice!

2/15/2012 7:53:35 AM

Dude, that's incredible. It's exactly what I was looking for. THANK YOU!

Now we need to figure out a way to add ads, allow you to bump your hosting plan, then add it to Google so you get the props you deserve.
