All,
we had strong QRM on 145.950 MHz due to the ISS. Most of the ARISSat SSTV images and voice messages were disturbed.
Just wondering why we can hear ISS packets on that frequency.

Hi Mike,
ich hatte heute Nacht den Empfänger mitlaufen und neben packet radio signalen waren auch andere Störungen hörbar, die wie Rückkopplungen klangen.
Anbei eine Sammlung von Aufnahmen von heute Nacht.
Gruss

Mike,
It was being used as a crossband repeater during the earlier test, with that as the input. Perhaps they did not change the frequency when they went back to simplex?

Oh so **THAT'S** where those packets were coming from! I kept hearing them too. Not trying to decode them, I thought they were coming from some local who hadn't turned off his packet TNC while listening to the satellite!
