Nothern Utah WebSDR Logo - A skep with a Yagi About the Northern Utah WebSDR server(s)

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.

There are several WebSDR systems online at this location offering coverage on all of the U.S. MF and HF amateur bands:

Another type of Web-interfaced, multi-user SDR system at this site uses KiwiSDRs that (theoretically) have continuous coverage from 0 through 30 MHz.  For more information about those receivers read the KiwiSDR section on the FAQ page.



Purpose of this WebSDR system:

One of the growing challenges of amateurs that wish to operate on HF is that of dealing with the crescendo of QRN at the typical home QTH, largely owing to the proliferation of devices that are, in their own right, power oscillators - namely, devices with switching power converters.  Now ubiquitous, these devices can be found in almost anything that is powered from the AC mains, from appliances to chargers to TV and computers.  Even if one, single device contributes relatively little to one's own receive noise floor on a given band, the sheer number of these devices - both in your residence and those of your neighbors - may contribute to the overall degradation of your receive capability, masking out weaker signals.

No matter your circumstance there are several reasons why you might frequent a WebSDR:
It should be noted that there are some instances where a remote receive system may be of limited benefit - specifically, some contest situations where there may be rules that limit/prohibit the use of such a station.

Having the availability of a "good" receiver site - that is, one that is "RF quiet", when coupled with a system such as a WebSDR can provide a wider benefit to a far larger number of amateurs than a single, dedicated remote receiver.  This system can accommodate a large number of simultaneous users, each independently tuning around and thus benefit the greatest number of users - not only from locations near the WebSDR system itself, but also those across the country and across the world.

In other words, a system like this can provide a bigger "bang for the buck" and benefit to more people than any other remotely accessible receiver system!



Operational hints:


Who's behind all of this?


The installation and maintenance of this WebSDR system is a joint effort of an informal group of amateur radio operators in Northern Utah with many locals offering support by donating equipment, their time and money.  This WebSDR is not associated with any particular club.

 


How can I donate to support this system?


Any monetary donations will be gratefully accepted and the easiest way to do that is via PayPal using the link below:

If you don't want to use PayPal and, instead, you wish to donate in another way (check, money order, gold bullion, cash in an envelope...) see the contact information below and send an email letting me know what you have in mind..

Acknowledgements of donations:


We would sincerely like to thank the following for their very kind $$$ donations.

Ron J.; Bill G.; Pat O.; Bill L.; Sid B.;  Jim P.;  Robb K., Rick L.

There have been been donors in addition to those above and we thank them for their help!  While we have configured PayPal to automatically notify us when someone donates, it doen't usually work so we have to log in and see - please bear with us - we'll acknowledge as soon as we can.

The amount - large or small - is very much appreciated and it helps keep the system running, not to mention the possibility of further enhancing it.  

Again, we wish to thank all of those who donated equipment, their time and/or money to make this system possible.




What are the future plans?

To make it better, of course!  In the future we hope to:




Why are there ads on these WebSDRs?

A WebSDR is not a natural resource!  To keep this WebSDR online there are some "fixed" expenses that we need to cover:
While we'd rather not have any ads at all, they are one way of providing a portion of the money that we'll need to keep this WebSDR running - and we'll try to make them as unobtrusive as possible.  If you run an ad blocker on your browser we do understand why, but consider "allowing" the ads on this site.

To be absolutely clear:



Contact information:

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 "wh2xyz@arrl.net".)

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!
