SWISSCUBE Telemetry 14-10-2013 13:15 UTC
Max elevation 72 degree, azimuth between 013 – 203 degrees.

And then there are those days when this hobby has a surprise for you, in the past I tried to download SWISSCUBE data but that wasn’t a success. This afternoon the little Cubesat was very strong and I was able to receive and decode the BPSK data.

One of the raw frames:

[241 Bytes KISS Frame (without CRC)]
from HB9EG1-1 to HB9EG1:

With the help of JA0CAW I can now decode the complete kiss file. Below the tlm output from the de decoder software.

SDR image where you can see the different tones of the BPSK signal. Decoding was done with the AFSK modem from UZ7HO.

Here an audio fragment from the BPSK data.
