Northern Utah WebSDR - Server #4
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 (#4) covers the 40-10 meter amateur bands in their entirety.
The receivers on this server (WebSDR #4) are connected to a log-periodic antenna (Hy-Gain - now U.S. Antenna Products - LP-1002) at 82 feet (25 meters) that covers 6 MHz through 40 MHz.
The antenna is on an 87° (relative to true North) heading which is optimized for covering the eastern half of the United States.
Farther abroad, the global coverage of this antenna includes Africa, the Caribbean, eastern South America (e.g. Brazil) with the Middle East and the Mediterranean at the northern periphery. Under certain conditions, Australia and New Zealand may be audible via "long path". Please note that this antenna is NOT rotatable - and it will never be!

The nature of this antenna makes it more susceptible to rain/snow static than the TCI-530 Omnidirectional antenna.

20 meter audio issues:
We are aware of an intermittent issue that causes "stuttering" on the 20 meter receiver on this server and we are attempting to determine the cause of this (recently appeared) problem. In the meantime, we are also implementing a script that we hope will detect and log most instances of this problem and reset it, but it may not catch the problem immediately.

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
Ever wonder where some of those loud static crashes are coming from? A look at the blitzortung.org U.S.A. lightning map
