Northern Utah WebSDR - Server #3

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 uses four servers to cover 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.

Covered by this server:

  • The 2 meter amateur band using a 5 element Yagi pointed (more or less) south, allowing reception of many repeaters and stations in the Salt Lake, Davis, Weber and Box Elder counties - which includes the areas from Salt Lake to north of Brigham City.
  • The 90, 41, 25 and 19 meter shortwave broadcast bands.
  • Also provided by this server is redundancy for the very popular 80/75 and 40 meter amateur bands if WebSDR1 (Yellow) goes offline, using these lower-performance receivers.

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

Notice:

As of 16 November, 2021, the 2200 and 630 meter receivers were moved to WebSDR #1 (Yellow).

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 parameters:
?zoom=n  Zoom "n" times
?squelch=1  Squelch audio

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.

Does the echo of your transmitted audio from the WebSDR drive you crazy? This circuit may help!
