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 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 (Green) covers mostly higher-frequency bands that are less likely to be active during the local nighttime - Check the band conditions at the bottom of the web page.
For lower-frequency bands, check the co-located "Yellow" server. You can read more about the receivers here.
Intermittent connectivity issues:
The Internet connectivity to the WebSDR servers has, at times, been suffering from jitter and delays. If you are experiencing drop-outs - whether they are on our end or your end - they may be mitigated by increasing the buffering using the Audio Buffering drop-down menu just below the WebSDR's volume control: A setting of 1 Second is suggested.
Thank you for your patience.
