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 and MF 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.

Notice: The W7RNA WebSDR in Sedona, AZ has been shut down by the owner after 6 years of operation - see the 21 October, 2018 entry in Latest News and known issues for more 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://ip.address/?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.

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

Ever wonder where some of those loud static crashes are coming from? A look at the blitzortung.org U.S.A. lightning map may help answer the question!
