Northern Utah WebSDR - Server #1
2200-40 Meters - Omnidirectional antenna

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.  

The Northern Utah 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 (Yellow) covers lower-frequency bands:

  • 2200 and 630 meters - active with groundwave out to about 700 miles/1000 km during the day and skywave at night.
  • 160 and 80/75 meters, active during local nighttime.
  • 40/60 meters which may be active day and night.
    • The 60M receiver has new hardware that covers from 4.8 to 5.4 MHz.  The original, lower-performance 60/49M receiver was moved to WebSDR #3 (Blue)
Check the band conditions at the bottom of the web page.

  • For 30, 20, 17, 15, 12, 10 and 6 meters on Omni antennas use WebSDR #2 (Green).
  • For 40, 30, 20, 17, 15, 12 and 10 meters using an east-pointing beam antenna check out WebSDR #4 (Magenta)
  • For 30, 20, 17, 15, 12 and 10 meters using a northwest-pointing beam antenna check out WebSDR #5 (Teal)
These server/antenna combinations may be accessed using the band selections below.
The 2021/2022 User Survey has finished and 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.

On-site KiwiSDR receivers are now available for testing - see the Kiwi FAQ page for more information.
