How to get started in software construction and where it can lead you – Heather M0HMO.
All you need to get started in Software construction is a personal computer (Windows, Linux, Mac – they’ll all do), some spare time and, if you want to make a ‘thing’ then some loose change.
There are three easy and virtually free routes into writing your own programs: develop applications that run on your PC using the free Qt environment; write programs to run on one of the Arduino boards (£3 from China plus a USB cable) using the free Arduino application; or go for the middle ground with a Raspberry PI (around £40) and a wi-fi connection.
Heather will take you through the setup for each of these and show you just how easy it is to go from flashing an LED through developing an ATV receiver to producing a fully-featured windows PC application such as her Mapper entry in the RSGB construction competition.

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.

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.

Mills On The Air 2022 – zaterdag 7 en zondag 8 mei 2022
Radio Amateur zoekt Molenaar en Molenaar zoekt Radio Amateur.
Verschillende dagen en weekends liggen in het verschiet, waarbij ook radio amateurs hun zenders en antennes in- of in de buurt van een molen opstellen.
Traditioneel “bezetten” radio amateurs in Nederland, Belgie, Engeland, Canada, Australie, … dan een molen. Van daar uit worden dan vele verbindingen gemaakt met andere radio amateurs – over de hele wereld.
Gewoonlijk werd / wordt deze activiteit gehouden op het weekend dat ook de Nederlandse nationale molendagen plaats vinden. ( Nationale Molendagen nu op 14 en 15 mei 2022 ).
De Engelse radio amateur clubs hebben blijkbaar besloten de “Mills On The Air 2022” activiteit een weekje eerder te plannen…
Voor Zuid Limburg zullen in ieder geval actief zijn ( de volle twee dagen of gedeeltes daarvan):
Van Tienhovenmolen in Wolfshuis – PA6TIEN team.
https://www.molendatabase.nl/nederland/molen.php?nummer=490
Molen van Hunnecum in Nuth – PD0DX team.
https://www.molendatabase.nl/nederland/molen.php?nummer=453
Molen De Korenbloem in Ospel – PD6MOTA team.
https://www.molendatabase.nl/nederland/molen.php?nummer=455
Kan zijn dat er toch nog meer molens in Limburg actief zullen zijn, als je op deze lijst wilt staan, laat het even weten….
