IARU-ATV-Kontest 2020


Der diesjährige ATV-Kontest der IARU Region 1 fand am 13./14. Juni 2020 statt. Aufgrund von Reisebeschränkungen in einigen Ländern, die durch die COVID-19-Pandemie verursacht wurden, wurden die Hauptwertungstabellen in 2 Abschnitte unterteilt. Abschnitt 1 war für Teilnehmer vorgesehen, die nur von ihrer Heimatstation aus operierten, während Teilnehmer, die von alternativen Adressen oder Portabel-Standorten aus operierten, an Abschnitt 2 teilnahmen. Es gab 92 Teilnehmer aus 8 Ländern im Wettbewerb, wobei alle Bänder von 432 MHz bis 76 GHz genutzt wurden.
Der Gesamtsieger der Sektion 1 für Feststationen war Wim, PE1EZU, während Francesco, IK3HHG, die Sektion 2 gewann und die höchste Gesamtpunktzahl erzielte. Die Ausbreitungsbedingungen schienen in ganz Südeuropa mit einer Anzahl von Kontakten (sogar auf 3 cm) über 200 km gut zu sein. Das beste DX war ein 70-cm-ATV-Kontakt zwischen F5AGO und F1CSY über 370 km. Die Beteiligung war gegenüber dem letzten Jahr stark erhöht (von 55 auf 92). Die meisten ATVer kamen aus Italien (33), dann 28 aus den Niederlanden und 15 aus Großbritannien.

Es gab 2 deutsche Teilnehmer, von denen DC8UG mit 1128 Punkten Platz 29 in Sektion 1 erreichte und DK7UP/P mit 2262 Punkten Platz 12 in Sektion 2.

ARISS contact 7.10.

An ARISS educational school contact is planned for Chris Cassidy KF5KDR with students at McConnell Middle School, Loganville, GA, USA. The contact is scheduled on Wednesday October 7, 2020 at approximately 14:16 UTC, which is 16:16 CEST.

The link to the ISS will be operated by the amateur radio ground station ON4ISS. Downlink signals will be audible in Europe on 437.525 MHz FM. Downlink frequency on UHF instead of VHF was chosen in order to avoid conflict with SSTV operations on VHF.

The event will be webcast on:

School Information:

McConnell Middle School is a Gwinnett County public school located in the northeastern suburbs of Atlanta, Georgia. McConnell has 2300 students in grades 6-8. Our student population is diverse with students from many different ethnicities. Our 8th grade students are in classes that earn high school credit for science, math, business, and some foreign languages while in middle school. ARISS is one part of our efforts as we work towards becoming a STEM certified school. Some of our students are involved in a competitive robotics club and an environmental club. School wide, there is also interest in sustainability projects including hydroponics and low impact gardening.
The McConnell Radio Club, KD4TGR, in its 6th year, is also part of our STEM certification goals. It is mentored generously by members of the Gwinnett Amateur Radio Society (GARS.org). Additionally, members of North Fulton Amateur Radio League (NFARL.org) are serving as the technical mentors for this ARISS. Several of our current and former students are licensed hams. Two of the students who will be asking questions are licensed radio operators: Daniel Reed (KN4SSI), technician class, and Maggie Colley (KM4PTW), extra class.
McConnell was originally scheduled to have this ARISS contact last April but that was postponed when the school system shut down due to the pandemic. We are back in school with many protocols in place to keep everyone safe. Some students attend school in person and some online. Students in our school and others in our school system will watch this ARISS contact via closed circuit streaming, some from their classrooms, some from their homes.
Our whole school community, students, faculty, and parents have been working towards this ARISS Radio Contact for well over a year. This ARISS event will stand out as the highlight in a school year when so many other events have been cancelled or minimized. Thank you for this opportunity.
