WebSDR - Server #3
80/40M back-up receivers and various SWBC using an Omnidirectional antenna
Plus 2 meters via south-pointing beam 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.
This WebSDR system covers 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.
Covered by this server:
- The 2 meter amateur band using 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 counties - which includes the areas from Salt Lake to north of Brigham City.
- The 90, 60, 49, 41, 31, 25 and 19 meter shortwave broadcast bands.
- Also provided by this server is redundancy for the very popular 80/75 and 40 meter amateur bands if WebSDR1 (Yellow) goes offline, using these lower-performance receivers.
- The 60 and 30 meter amateur bands are covered by the "60-49M" and "31-30M" meter receivers, respectively.
- A high-performance receiver dedicated to 60 meter operation may be found on WebSDR #1 (Yellow) - Link.
The 2021/2022 User Survey has finished and you may see the results here.
2 meter reception significantly improved:
In August, 2022 the 2 meter antenna - a south-pointing, 5 element Yagi - was relocated away from the (RF-noisy!) building and to a much greater height on the tower with the beam antennas. Doing this almost completely eliminates all QRN from computers, networking gear and switching power supplies, lowering the noise floor considerably. The added height offers better signals due to the reduction of Fresnel (and other) effects, allowing an estimated 15 dB or so improvement in overall performance.
In late July, 2023 the filter/amplifier module was also relocated to the remote tower, further reducing the noise floor and improving reception.
For Salt Lake City area coverage on 2 meters and 70cm look for the Salt Lake Metro buttons, below.
The Salt Lake Metro server now has a narrowband, high-performance 2 meter receiver dedicated to Earth to Space reception of signals from spacecraft.

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.
Does the echo of your transmitted audio from the WebSDR drive you crazy? This circuit may help!
