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 a 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. There may be other issues with CatSync - read here.

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.

60 Meter rule changes
As per FCC Report and order 25-60 link released 9 December, 2025, becoming effective 30 days after being published in the Federal Register - there are changes to the "60 meter" band as follows:

"Channel 3" will be a contiguous 15 kHz "band" from 5351.5 to 5366.5 kHz.
The MAXIMUM ERP level for this segment will be 9.15 Watts ERP (15 watts EIRP): It will remain at 100 watts ERP for channels 1, 2, 4 and 5.

This means that running 100 watts ERP will be no longer allowed on the "old" channel 3 frequency.

The maximum bandwidth of any mode on this or any other 60 meter channel is/will be 2.8 kHz.
The changes to "Channel 3" more closely reflect how 60 meters is allocated in many other parts of the world.
For additional details, see the 11 December, 2025 entry of the Latest News (link) page.

These (pending) changes are now reflected in the markings on the WebSDR waterfalls.

Notice to those using the Chrome web browser:

A recent update to the Chrome Web browser seems to have broken audio for many web sites - including this WebSDR: This problem has nothing to do with the WebSDR itself. The nature of this problem is unknown - but if it's like a previous "bug" in Chrome that broke audio several years ago, a newer version of Chrome may fix the problem.

In the meantime we suggest that if you have a problem with WebSDR audio in the Chrome browser that you use the Firefox, Opera or Safari browser instead.
