Hi Matthias,
This is not AmicalSat, when did you recorded it ? There is two possibilities of failures. The first is bad attitude of the satellite when transmitting (not nadir, remember that the ADCS is not working, unfortunately), the second is a problem in the planed task (this is the first time we use a planned task for a S-band transmission, I will double check everything.)
I will keep the list updated about the next session.
Have a good day, Julien F4HVX

Hi Julien,
during the last pass of AMICALSAT over Europe I did not receive a 3-5 minutes long data transmission.
However I did receive a short transmission at 2414.957 MHz at 09h40m34s UTC which lasted only a few seconds. Enclosed is a screenshot.

I have a lot of noise due to many WLAN stations close by. The frequency in the screenshot of 415.375 MHz corresponds to a receive frequency of 2414.957 MHz.
I wonder whether this might have been a transmission of AMICALSAT.
I have a I/Q baseband recording which I can make available if someone wants to try to decode the signal.
Kind regards
Matthias
