9 mei 2021 | PA0EHG | Drie jaar propagatiemetingen op 80 meter |
Het baken van Robert PA0RYL op 3.555,555 kHz, heeft al menig amateur bezig gehouden. Het feit, dat je met 10mW output op 80 meter propagatie onderzoek kunt doen, heeft menige rapporteur verbaasd. Maar er is niemand, die er zo toegewijd en enthousiast mee aan de slag is gegaan als Hans PA0EHG. Gedurende 3 jaar heeft hij dag en nacht het baken gemonitord en de gegevens vastgelegd. Hij heeft daarbij diverse bijzondere waarnemingen gedaan. Dat heeft er op zijn beurt toe geleid, dat hij zich is gaan verdiepen in de theoretische achtergronden van deze verschijnselen. Het verheugt ons dan ook bijzonder, dat hij ons deelgenoot wil maken van zijn afsluitende conclusies. |

Deze avond zal Jan PA3AAN / ON4PAL een lezing houden over spy radio, en dan wel in het bijzonder over de Type 3 MK2 (B2) spyset. Dit type is in de tweede wereldoorlog gebruikt.
Een prima onderwerp om weer terug in de historie te duiken en te zien en horen welke technieken toen zijn ingezet.
Helaas gaat de radiomarkt dit jaar niet door.
De huidige prognose van de corona cijfers en maatregelen laten het niet toe om verantwoordelijk een markt te organiseren. Daarnaast merken we dat, geheel begrijpelijk, een groot aantal standhouders een afwachtende houding aanneemt met het aanmelden voor deelname aan de radiomarkt. Hierdoor is de planning niet op tijd rond te krijgen.
2021 Hamvention Cancellelation
Unfortunately, several setbacks in the recovery from the COVID-19 pandemic make necessary the difficult decision to cancel Hamvention 2021. Hundreds of volunteers have been working to do everything necessary to bring this Hamvention to the many amateur radio enthusiasts and vendors who support the Dayton Hamvention.
Vaccine distribution both in the United States and around the world is lagging behind what was planned. In addition, the emergence of a more communicable form of the COVID-19 virus increases the potential for further public health problems in the next few months. We make this difficult decision for the safety of our guests and vendors.
Those who had their tickets, inside booths or flea market spaces deferred last year will be deferred again. Those who purchased 2021 tickets, inside booths or flea market spaces will also be deferred. If you desire a refund instead please email tickets@hamvention.org and we will contact you.
Stay tuned for information about a QSO party for the 2021 Hamvention weekend. We are looking forward to the 2022 Hamvention!!!

There will then be a sequence of videos showing someone competing in a 144MHz event which shows not just the taking and plotting of bearings but the whole decision-making process that results in locating the hidden transmitters rapidly. It is the challenge of this process that can make ARDF so enjoyable. The webinar will also feature contributions from Kim Taylor, M0KNV giving the perspective of a regular Club member being talked into trying ARDF and from Flora Jolly who was persuaded to go out and try ARDF with her Dad David, M0JCO. The presentation wraps up with a review of ARDF coverage across the RSGB Regions and the steps currently being taken by the RSGB Board and the ARDF Committee to make provision for ARDF in all regions.
