Northern Utah WebSDR - Server #5
30-10 Meters - Northwest-pointing beam
U.S. West Coast, Alaska, Asia, Australia, New Zealand, Pacific
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 WebSDR (#5) uses a KLM 10-30-7LPA log-periodic antenna that is oriented to a bearing of northwest - approximately 278° (true) at a height of 53 feet (16 meters) above ground - for coverage of the north and western portions of the U.S. (including Alaska) and Canada. For DX it covers Australia and much of Asia. This antenna provides continuous coverage from 10 through 30 MHz. This antenna was kindly donated by the Ted Elliot Hartson trust.

Just like the beam on WebSDR #4, this antenna is NOT rotatable.
As of 28 August, 2022, this WebSDR is fully operational: The filtering and amplifying hardware has been built, tested and installed and the "10 Meter Hi" receiver is now in operation, allowing reception of all amateur frequencies from 30 through 10 meters.
There is an occasional issue with power line noise. We believe that we have identifed the hardware involved and are working with the power company to get it resolved.
The 2021/2022 User Survey has finished and you may see the results 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.
Does the echo of your transmitted audio from the WebSDR drive you crazy? This circuit may help!
Ever wonder where some of those loud static crashes are coming from? A look at the blitzortung.org U.S.A. lightning map may help answer the question!
Following a complete rebuild of the operating system on this WebSDR, we are still getting things sorted out.
Expect occasional service/signal interruptions as we do additional testing/configuration - see the Latest News page for more information. If you experience interruptions on this server try WebSDRs #2 or #4 as temporary alternates.
