Northern Utah WebSDR - Server #1
2200-40 Meters - Omnidirectional 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.

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 server (Yellow) covers lower-frequency bands:

2200 and 630 meters - active with groundwave out to about 700 miles/1000 km during the day and skywave at night.
160 and 80/75 meters, active during local nighttime.
40/60 meters which may be active day and night.

Check the band conditions at the bottom of the web page.

For 30, 20, 17, 15, 12, 10 and 6 meters on Omni antennas use WebSDR #2 (Green).
For 40, 30, 20, 17, 15, 12 and 10 meters using an east-pointing beam antenna check out WebSDR #4 (Magenta)
For 30, 20, 17, 15, 12 and 10 meters using a northwest-pointing beam antenna check out WebSDR #5 (Teal)

These server/antenna combinations may be accessed using the band selections below.
