NOTE: New version coming soon with updated radio database!

Uses a database of US radio emitters and iPhone location services to provide a view of the estimated spectrum utilization your current location.

Use this with low power personal FM equipment, music player dongles (like the iTrip(tm) broadcasting your iPod or other MP3 player to your stereo), or just to get an idea of the spectrum usage in any location.

- "Offline" access included, perfect for a road trip where you are in the middle of nowhere and don't have an internet connection but still can't find a good clear frequency (iPhone must still be able to determine location)
- Clearest stations are highlighted. These provide several options that should provide clear reception.

Does not take into account geography or man-made obstacles. US emitters only included in this package. Other localities to come.
