About ARISS:

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation(AMSAT), the American Radio Relay League (ARRL), the ISS National National Aeronautics and Space Administration (NASA).

The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts and mathematics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org

DATV-Test auf 2m

Die niederländische Mitgliedsvereinigung der IARU, VERON, ermutigt Funkamateure, DATV im 2-m-Band am 22. August zu benutzen, um zu demonstrieren, dass das Band für DATV geeignet ist.
– Termin: Samstag, 22. August 2020
– Zeit: 1200-1600 GMT
– Frequenz 144,600 MHz oder 145,300 MHz
– DVB-S oder DVB-S2, Symbolrate 125 kS/s
VERON empfiehlt, die Webseite https://dxspot.batc.org.uk/
für die Rücksprache zu verwenden. Weitere Einzelheiten auf der VERON-Webseite
https://tinyurl.com/NetherlandsVERON

Um nicht das gesamte 2-Meter-Band zu nutzen, was andere Verbindungen unmöglich macht, wurde die Bandbreite auf ca. 160 kHz reduziert. Dies ist mit einer Symbolrate von 125k erreichbar. Außerdem ist die Versuchsdauer auf 4 Stunden (12:00 – 16:00 UTC) begrenzt.
Der British Amateur Television Club verfügt über eine umfangreiche Wiki – Seite für RB-TV:
