The Russian Woodpecker over the horizon radar, a blast from the past – Keith KI6BDR.
Hidden deep in a serene forest yet taller than the clouds, standing in surreal beauty is an antenna array like none other on earth, having an aperture area greater than 15 U.S. football fields. One of the great wonders of the world – a top secret Soviet radar, so secret that even the name is uncertain, for it had many. It was the Russian Woodpecker. It was the Steel Yard. It was Duga.
The story of this top secret place is one of mystery and intrigue. Now abandoned, a rusting testament to man’s cold war hubris, almost all popular accounts on the web are seriously flawed – victims of deliberate disinformation. Where did it come from? What did it do? Did it transmit? Did it receive? Was it the first of three, or the third of two?
Keith Snyder, KI6BDR, has been busy reverse engineering to uncover truth before time erases history. Keith shows visible engineering clues that reveal the mission and correct the history of the huge “Duga 3” antenna Array. The Duga 3 is located a few kilometers from the Chernobyl nuclear power plant site. Although it has fallen into disrepair, it stands today due only to a hasty exit forced by radiation from the
Chernobyl nuclear accident. The nuclear accident ironically protected the array from dismantlement, a reprieve from all but the ravages of time. The antenna array today attracts tourists who visit Chernobyl. It is one of the 8th wonders of the world due to its Titanic size.

Daar de horeca nog steeds om 22.00uur haar deuren moet sluiten, vervroegen wij onze lezing. Deze maand starten wij om 19.30uur lokale tijd!!!
Loek PE0MJX heeft een boeiend verhaal over zijn zelfgebouwde HF-Fet eindtrap voor ons in petto!
Denk er ook aan dat je een QR-code moet kunnen voorleggen om het horeca gedeelte binnen te komen voor een drankje! Ook de regel van mondkapje dragen als je je verplaatst en de 1,5m afstand gelden er!
We hopen vele van jullie weer eens te mogen begroeten op deze fysieke bijeenkomst!

The bluffer’s guide to digital voice – Tim GW4VXE.
Tim will provide a quick overview of the most common digital modes (D-STAR, DMR and Fusion) as well as some of the less common modes. Tim will explain how you might use them.
Which mode is the best? Tim will look at code-plugs and hotspots and try and demystify some of the jargon for you.
Technology permitting, he’ll try and do a demo with the chance for a little audience participation. Rather than being a heavy session, the emphasis will be on light but informative content.

Deze avond gaat Loek PE0MJX (ook bekend van de websdr Maasbree) ons alles vertellen over zijn zelfbouw HF PA en antenne tuner. De afweging tussen het zelf helemaal opnieuw ontwerpen of gebruik maken van kits ? Hoe je een keuze maakt, wat er allemaal bij komt kijken. En waar je allemaal tegenaan loopt tijdens de voortgang van het project.
Wil je al een kort voorafje proeven, kijk dan ook eens op de website van Loek.
