Duga radar

What’s that then? I hear you ask. Well since I became a radio amateur (M0ESB) back in Feb 2003 anything regarding radio has fascinated me.

The Duga or – Russian woodpecker issue of the early 80s has always been an item of interest to me. It was allegedly constructed as a Russian over the horizon early warning system and was replaced in the late 80s when satellite systems took over the early warning mantle.

However it obtained notoriety by creating havoc on the airwaves worldwide for quite a considerable period of time.

This video by a fellow Amateur radio enthusiast M3HHY explains quite eloquently, in 11 minutes what the issue was. Some great photos of this absolutely massive antenna array can be seen in this video.

And whilst we are still here this is what Wikipedia has to say:

The duga system was extremely powerful, reaching over 10 MW, and emitted in the shortwave radiobands. It was given the nickname Russian Woodpecker by shortwave listeners for its emissions randomly appearing and sounding like sharp, repetitive tapping noises at a frequency of 10 Hz. The random frequency hops often disrupted legitimate broadcasts, amateur radio operations, oceanic, commercial, aviation communications, and utility transmissions, resulting in thousands of complaints from many countries worldwide.

I hope you find this as fascinating and informative as I have. Radio remains to this day special to me. I’d sooner be listening to it in any form rather than watching a tv. In my eyes or should I say ears, it was the most significant invention ever made, if only Marconi knew back in the 1890s just how important this communication method would become he would have been blown away. It has helped to shape so much, our modern day world, and how we communicate with each other on a daily basis.
