Databases: Help! I Need Help Finding an Empty Radio Frequency (U.S. only)
You've just purchased a iPod, portable satellite receiver, or something similar. Now, you need to find a radio frequency on the FM dial to listen to your tunes, satellite stations, etc. In some situations the FM transmitter is built into the product, in other cases, you'll need to buy an i-Trip or something similar.
With the caveat that numerous variables come into play (in other words, there is no guarantee that these suggestions will work as predicted), Radio-Locator.com, one of the largest databases of radio stations in the world, now offers an "Unused FM Frequency" database for the U.S. only.
It's easy to use. Simply enter a Zip Code and State (actually, you don't even need to enter the state) and in a second you'll see a graph and suggestions on the best frequencies to try so you can clearly hear whatever the device that requires an FM frequency. Of course, if you're mobile, say you use an i-Trip, you'll either need to track your route entering each Zip Code or just be ready to start searching for new frequencies once you leave your neighborhood.
+ The database looks at what frequencies are in use by over-the-air FM stations
+ The strength/power that those stations transmit at
Again, these are only suggestions and places to begin your search for a clear frequency. The only way to know for sure is to fire up the device, your FM radio and begin scanning.
