Northern Utah WebSDR - Server #4
40-10 Meters - East-pointing beam
Eastern U.S. and Canada, Africa, Southern Europe
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 above is informational - you will still be able to hear signals outside the pattern of the antenna. Click on any of the above images for a larger version. Maps courtesy NS6T's web site.
The nature of this antenna makes it more susceptible to rain/snow static than the TCI-530 Omnidirectional antenna.

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 40 meters, try WebSDRs #1 or #3 and for 30-10 meters, try WebSDRs #2 and #5 as temporary alternates.
