Northern Utah WebSDR - Server #2
30-6 Meters - Omnidirectional antennas

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 WebSDR 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) uses omnidirectional antennas to cover the 30, 20, 17, 15, 12, 10 and 6 meter bands, many of which are less likely to be active during the local nighttime - Check the band conditions at the bottom of the web page.

  • For reception on the 40, 30, 20, 17, 15, 12 and 10 meter bands using an east-pointing beam antenna, try WebSDR #4 (Magenta).

  • For reception on the 30, 20, 17, 15, 12 and 10 meter bands using an northwest-pointing beam antenna, check out WebSDR #5 (Teal).

  • For 160, 80/75, 60 and 40 meters, check the co-located WebSDR #1 (Yellow) server.  You can read more about all the receivers at the Northern Utah WebSDR here.

The 2021/2022 User Survey has finished: You may see the results 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

Additional URL parameters are described on the "FAQ" page here.

If you find that CatSync doesn't work with this WebSDR, add "?10hz" to the URL.

Remember: If you don't do something (e.g. retune, adjust bandwidth, volume) this WebSDR will time out after 120 minutes. If it does time out, refresh the browser.
