Listen to and control an online short-wave receiver

Posted by Trevor on

I am not one who is interested in streaming the audio of a short-wave broadcaster over the Internet. That is not what I have a short-wave radio receiver for. Once it is streamed online, it is not radio anymore. However, in this case, I will make an exception:

On this page you can listen to and control a short-wave receiver located at the amateur radio club ETGD at the University of Twente [the Netherlands]. In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio.

This site, which in 2008 was the very first WebSDR site ever, was finally reactivated in July 2012 after an interruption of more than 1.5 years

If you live in another part of the world, and you would like to tune into the radio signals in the European area, this is the next best thing to being there with your own radio receiver. One can direct entry a frequency to listen to, or one can move the “needle” around listening to transmissions. Frequency range covers the entire short-wave spectrum (1MHz to 30MHz).

I like to direct entry the three frequencies for the National Research Council (NRC) short wave station broadcasts (CHU) that amazingly travel from Canada to the Netherlands. There are also a lot of interesting and entertaining short-wave radio broadcasts one can tune into using the site; including the mysterious "buzzer station" from Russia, 4625 kHz (night), the Russian "pip", 5488 kHz (day),  3758 kHz (night), and the Russian "Squeaky Wheel", 3828 kHz (night).

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.
