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

This WebSDR server is located at a site near Corinne, Utah, at a site previously used for HF propagation and research and 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.

This WebSDR was put online at this site on 28 February, 2018 with the help of many local amateurs.  As such, there a number of technical issues to be solved, many of which are detailed in the "Latest News" web page, linked below.

There are currently two WebSDR systems online at this location:

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!

Who's behind all of this?

The installation of this WebSDR system is a joint effort of a group of amateur radio operators in Northern Utah.  An incomplete list of those who have contributed to making this project possible includes Mike, KC0JRE;  Glen, WA7X;  Pat, AD7V;  John, K7JL;  Randy, KG7GI and Clint, KA7OEI.

Why are there ads on the WebSDR?

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 clear:  We will be pleasantly surprised if we can completely support the WebSDR with ad revenue which is why we'll also be encouraging donations.  None of us will actually be making money on this - we are hoping that it will cover at least some of our ongoing expenses.

How can I help support this system?

In addition to visiting the merchants represented by the ads, we are happy to accept donations.  At the moment we are still working on the best way to do this (perhaps a PayPal "donate" button) but if you want to help, use the contact information below.

What are the future plans?

To make it better, of course!  This system had been running at another site for testing for about 6 weeks before it was relocated and installed at the current site on 28 February, 2018 - and we are still working out a few bugs.  In the immediate future we hope to:
