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.

Dutch PACC contest.
Dutch PACC contest.
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.

Breaking the big story,
when amateur radio was the only way – Laurie G3UML.
BBC journalist and long-time RSGB member Laurie Margolis broke the fact of the invasion of the Falklands through amateur radio. Here’s how…
He will also cover his involvement in the 1970 King Hussein story.
In this 40th anniversary year since the Falklands War, we are delighted to have this presentation from Laurie.

2022 PACCdigi contest
Starts: April 17 at 07:00 UTC
Ends: April 17 at 19:00 UTC
Naast de PACC contest willen we dit jaar een contest organiseren waarin digitale modes aan de orde komen. De contest vindt plaats op 17 april. Evenals de PACC contest is het een wereldwijde contest waarin de Nederlands provincies als multipliers worden gebruikt. Er is voor deze uitvoering gekozen voor een 12 uurs contest in de mode RTTY en/of FTx. Naast de individueel kan ook in de MOST (multi operator single transmitter) klasse deelgenomen worden.
Het reglement is hier te vinden.
De radiomarkt is onder voorbehoud! Mochten de Corona maatregelen het tegen die tijd niet toelaten dan gaat de radiomarkt niet door. We zullen dit tijdig melden op onze website en via de diverse (online)mediakanalen. Eventueel betaalde kraamhuur wordt dan aan u teruggestort.

Radiokampweek 2022
Zoals al eerder aangekondigd was de kans aanwezig dat we in 2022 niet direct terecht konden in de week van Hemelvaart op onze nieuwe locatie. Helaas is dat nu ook gebleken. Er waren reeds te veel reserveringen geplaatst voordat we überhaupt met de nieuwe locatie in gesprek waren.
Hierdoor zal de radiokampweek éénmalig in een andere week worden georganiseerd. In samenspraak met onze contactpersoon hebben we gezocht naar een week waarin toch een vrije dag zit, en die niet te kort op de zomer, Pinksteren en Pasen zit. We zijn uitgekomen op de week van Koningsdag. Dit zou dus betekenen dat de radiokampweek plaats vind van zaterdag 23 april t/m 1 mei 2022. We willen dan de radiomarkt op zaterdag 30 april organiseren. De nachtjacht zal dan worden verplaatst naar een moment eerder in de week. Houdt hiermee dus rekening tijdens je vakantieplanning.
In 2023 zal de radiokampweek zoals gebruikelijk wel weer gewoon in de week van Hemelvaartsdag worden georganiseerd.
Locatie
De radiomarkt vindt plaats op Recreatiepark de Lucht te Renswoude. Renswoude ligt vlak bij Veenendaal op de grens van de provincie Utrecht en Gelderland. Dit zal voor de bezoeker ongetwijfeld betekenen dat er naast de bekende ook nieuwe verkopers te vinden zullen zijn, én voor de verkopers weer een gedeeltelijk nieuw publiek. Voor de standhouders veranderen de voorwaarden niet:
- Het zal voor standhouders mogelijk zijn om auto/bus/aanhangen achter de kraam te plaatsen.
- Het is voor standhouders die van ver moeten komen mogelijk om te overnachten in hun eigen voertuig. Er is bij de ingang een speciale parkeerplaats ingericht voor het overnachten in een camper. U kunt voor een reservering contact opnemen met Recreatiepark de Lucht. Let op: Wij hebben geen invloed op deze reservering in het geval de radiomarkt niet kan doorgaan als gevolg van Corona maatregelen.
Openingstijden
De radiomarkt is geopend voor verkoop van 8.00 uur ’s morgens tot circa 15.30 uur ’s middags. Voor verkopers is het marktterrein geopend vanaf 7.00 uur tot 7.45 uur voor het opbouwen. De verkopers kunnen op twee manieren hun waar aanbieden. Je kunt een kraam huren of deelnemen aan de kofferbak verkoop.

The story of Jodrell Bank –
Ian G0DMU.
Professor Ian Morison, G0DMU will give a review of the history of Jodrell Bank, one of the world’s premier radio astronomy observatories; from its founding in 1945, the completion of the Mk I (now Lovell) radio telescope in 1957 – still the third largest fully steerable telescope in the world – and the building of the MERLIN array in the 1980s and 90s.
The MERLIN array has the same resolution as the Hubble Space Telescope and many collaborative observations have been made over the past 30 years. Its seven telescopes also link up with others across Europe to provide an instrument whose resolution far exceeds that of optical telescopes.
Some of its most exciting discoveries will be discussed in the context of how radio observations are made – many of which can complement those made by optical telescopes.
