Northern Utah WebSDR
Welcome to the new landing page for the Northern Utah WebSDR
Please read the information below before scrolling down to the new links for the WebSDRs

You may have noticed that as of mid-June, the connectivity to the Northern Utah WebSDR system has become extremely poor at times.  Because of these connectivity issues, the Northern Utah WebSDR system will be moving to a new ISP (Internet Service Provider) and this means that the way that the WebSDR servers are accessed will change.  To facilitate this change, your "old" bookmarks will, for the time being, be redirected to this page:  This redirect is not a "hack" of the WebSDR site, but is completely intentional.

Because of this change, the URLs of the WebSDRs will be different and your previous links and bookmarks will not work once the system has moved to the new ISP unless you have updated them to use the links on this page.  You have been warned!

There will likely be a period during this transition - perhaps lasting a few days - during which the Northern Utah WebSDR system will be down.  Even if the WebSDRs themselves are offline, this landing page will remain online and will be updated with the latest news.

For more detailed information as to why this change is occurring, please read this.
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:
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.

The above URLs will not change once we switch to the new ISP.

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.
