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 
leider
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:
