Northern Utah WebSDR - Server #1

This WebSDR is located near Corinne, Utah, about 80 miles (94km) north of Salt Lake City and about 14 miles (23km) east of the Golden Spike National Historic Site.  

This system has coverage on all U.S. amateur HF, MF and LF bands, 2 meters, the bottom 1 MHz of 6 meters, and several shortwave broadcast bands - see the Technical Info page for more details.

This server (Yellow) covers lower-frequency bands: 160/80/75 meters, active during local nighttime and 40/60 meters which may be active day and night. Check the band conditions at the bottom of the web page.  For higher-frequency bands, check the co-located "Green" server.  You can read more about the receivers here.

The 2019 User Survey has finished - Results may be found here.

A lot of changes have recently occurred at the Northern Utah WebSDR - see the Latest News page for details.

To invoke this page with a preset frequency and mode, append "/?tune=(freq kHz)(mode)" to the URL and save it as a bookmark as in: http://[WebSDR's URL]?tune=7200lsb


Remember: If you don't do something (e.g. retune, adjust bandwidth, volume) this WebSDR will time out after 90 minutes. If it does time out, refresh the browser.

On-site KiwiSDR receivers are now available for testing - see the Kiwi FAQ page for more information.
