Northern Utah WebSDR - Server #2

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 (Green) covers mostly higher-frequency bands that are less likely to be active during the local nighttime - Check the band conditions at the bottom of the web page.  For lower-frequency bands, check the co-located "Yellow" server.  You can read more about the receivers here.

The 2020 User Survey has finished - Results may be found here.

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.

Other WebSDR systems - Western U.S.:  KFS, Half-Moon Bay, CA   W7RNA, Sedona, AZ   AI6VN, Maui, HI

Eastern U.S.:   K3FEF, Milford, PA, NA5B near Washington DC and N4BBQ, Dalhonega, GA
