Hallo Tom und Forum
NanoSail-D2 werde ich wieder in meine OSCAR-News und in die Satellitenliste
auf www.amsat-dl.org aufnehmen. Zum Sat: Streng genommen ist es NanoSail-D2
und nicht '-D'. Diese Mission war 2008 gescheitert. Die Quelle ist mir
nicht mehr bekannt.
Hier noch ein paar Links:

Interessant ist, dass der Downlink bei WA4NZD auf 437.275 MHz gehört wurde.
Hier steht quasi noch mal das selbe wie bei der ARRL:
