Northern Utah WebSDR
Welcome to the new landing page for the Northern Utah WebSDR

There are three WebSDR systems available via the links below - Please remember to update your bookmarks!
  • WebSDR1 (the "yellow" server) - This WebSDR server covers the 160, 80/75, 60 and 40 meter amateur bands as well as the AM broadcast band, the 120, 69 and 49 meter shortwave broadcast bands.
  • WebSDR2 (the "green" server) - This WebSDR server covers the 30, 20, 17, 15, 12, 10 and the 6 meter (bottom 1 MHz) amateur bands and the 31 and 13 meter shortwave broadcast bands.
  • WebSDR3 (the "blue" server) - This WebSDR server covers the 2200, 630 and 2 meter amateur bands.  It also covers the 90, 41, 25 and 19 meter shortwave broadcast bands and provides redundancy for WebSDR1's coverage of the very popular 80/75 and 40 meter amateur bands.
We believe that we have fixed two earlier issues:
  • The above links should now work with the Microsoft Edge browser.
  • You can now apply the frequency and mode to the URL, as in:
Possible issue:
  • We have been getting occasional reports that the "memory" channels on the WebSDRs - which use cookies placed on your computer - aren't working.  We have been unable to replicate this issue using configurations typical to most users (e.g. Windows or IOS and using the Chrome, Firefox, Safari and Edge browsers):  As far as we can tell, it may be specific to certain browsers on some Linux distributions.
If you get a "blank" page from the above three links:
  • Try a different browser:  Recommended browsers include Chrome, Firefox and PaleMoon.
  • If that doesn't help, try a different computer on the same Internet connection - and if that works, check the Firewall settings on the first computer:  You may have to put "" and the WebSDR servers themselves in a "trusted" zone and/or put on the "allowed" list..
  • If you get a blank screen on both computers on the same Internet connection there may be a firewall/router setting that prohibits redirects, requiring that "" be put into the "trusted" zone and/or put on the "allowed" list.
If you discover other issues related to browser compatibility, please let us know via the contact information on the "About this WebSDR and contact info" page.

Other WebSDR systems:

For different geographical coverage and/or until we get our issues sorted out, here are a few WebSDR system to use if you find the Northern Utah WebSDR either offline or unusable:

Western U.S.:

  • KFS, Half-Moon Bay, CA  - 160, 80, 40 and 20 meter coverage.  This is the best alternative to the Northern Utah SDR for "local" (e.g. Western U.S.) coverage.
Eastern U.S.: For a list of WebSDR systems worldwide, go to the page.

The Northern Utah WebSDR
is operated by a group of volunteers in conjunction with a non-profit organization set up specifically for the support of the WebSDR.  Many of these volunteers are members of other local amateur radio clubs, but the Northern Utah WebSDR itself is not associated with any of these clubs.  See the about page for more information.
