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 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 (blue) covers 2 meters, the 90, 41, 25 and 19 meter shortwave broadcast bands and the "new" 2200 and 630 Meter amateur bands along with the so-called 1750 meter "LowFer" band:  You can read more about these receivers here.  Also provided is redundancy for 80/75 and 40 meter coverage, allowing this server to cover these (the most popular bands) if WebSDR1 (Yellow) goes offline, using these lower-performance receivers.

2 Meter coverage:  The 2 meter receivers use a preamp and 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 and nearby counties which includes the area from Salt Lake to north of Brigham City.

The "2200M/1750M" receiver is operational using an e-field whip antenna. A noise source recently appeared that may affect this band, the source of which is under investigation.

The 2019 User Survey has finished - Results may be found here.

Have you been having trouble hearing WebSDR audio on your Apple device?

Have an Apple device running iOS 13 with Safari and can't get audio from this or other WebSDRs or KiwiSDRs?  Look here for information that may "fix" the problem.  If you continue to have issues with Apple devices, please let us know via the email link on the About page.

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


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!
