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

Have you been having trouble hearing WebSDR audio on your Apple device?

Have an Apple device running iOS 13 with Safari and can't get audio from this or other WebSDRs or KiwiSDRs?  Look here for information that may "fix" the problem.  If you continue to have issues with Apple devices, please let us know via the email link on the About page.

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 and  W7RNA, Sedona, AZ

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

Notice:

We have been experiencing issues with this WebSDR (#2, Green) causing waterfall and audio issues - More information on the Latest News web page.

We believe that we have found and fixed the problem - but this is a computer, so who knows for sure? If there are issues with this server, please try WebSDR #1 for 40 meters and WebSDR #4 for 20 meters and up.
