About the Site

The radio frequency scan repository is designed to help sound mixers and other technicians find the clearest wireless frequencies wherever they go. Let us know at if you have ideas for features you'd like to see or run into problems.

Please note that these scans only present a snapshot of the radio frequency activity at that moment and should be regarded as guides rather than gospel.

We've written up a small guide that represents our best understanding of the US frequency sitation as it stands now, but any wireless mic frequency use is at user's own risk. Some frequencies may have output power limits or require licensing or special permission to use. Please consult FCC regulations for more info.

Submitting Scans

Want to help collect data? We'd love to have your scans! Here's what we need:

  1. The make and model of the scanner.

  2. The date and approximate time of the scans.

  3. The scan location and whether it was exterior or interior. This can be latitude/longitude points, the name of a building, an address, or intersection - anything that we can plug into Google maps.

  4. The scan data in a text or spreadsheet format. Right now, .csv is preferred, but we can probably handle most other formats. If you have multiple scans or your scanner breaks up the scans into a number of small passes, that's fine - the site will create an average file for scans performed around the same time.

  5. Optional - Your name if you'd like to be credited and/or your website to link to.
