Nothern Utah WebSDR Logo - A skep with a Yagi WSPRNET monitoring at the Northern Utah WebSDR

This WebSDR server is located near Corinne, Utah, at a site previously used for HF propagation research.  It is about 60 miles (94km) north of Salt Lake City and 14 miles (23km) east of the Golden Spike National Historic site where, in 1869, the first transcontinental railroad was completed, linking the eastern and western United States by rail for the first time.

The main receive antenna at this site is a TCI Model 530 omnidirectional Log Periodic which is (mostly) circularly-polarized and optimized for higher-angle incident waves, having up to 6dBi gain.  Go to the "Technical Info" page for more detail about the gear used at this site.  This WebSDR system was put online at this site on 28 February, 2018 with the help of many local amateurs.

WSPR reception and reporting at the Northern Utah WebSDR:

Because of its location, good antenna and low noise, the facilities at the Northern Utah WebSDR are used for WSPR reception and reporting to the web site.  At present, all of the bands listed below are monitored 24 hours a day.
The monitoring of these bands is facilitated with the use of several KiwiSDR receivers, stand-alone Linux-based receivers capable of reception from 0 through 30 MHz.

Rather than using the KiwiSDR's built-in WSPR decoder, audio-only connections are made (via the network) to the on-site KiwiSDRs using the "KiwiRecorder" script, one connection per monitored frequency range.  Synchronized to UTC, these recordings are processed at the end of each  minute WSPR period by another machine that is on site using the "WSPRD" program and the results are automatically forwarded to the wsprnet server.  By having an "audio-only" connection to the KiwiSDR, its limited processor resources are minimially taxed, off-loading the computationally-intensive decoding to another, faster machine.

WSPR reports from the Northern Utah WebSDR site currently use the callsign KA7OEI-1.

If you wish to find out how you can contribute to this project, or if you have any questions/comments that weren't answered on the "latest news", "FAQ" or "technical info" pages, you may send an email to Clint, KA7OEI using the callsign at arrl dot net.  (Example:  If my call was "wh2xyz" the email address would be "".)

If you wish to contact me, please avoid using an email service that has one of those "Please fill in this form to reply" type of SPAM filters.  If you really want me to reply, please have the courtesy to allow me to do so without having to fill out a form and supply extra personal information to who knows where, etc. - I wasn't planning to sell your email address, anyway!
