[ENSO] : RadioHam game begins!

1

Hello,

The CSUM is doing a RadiHam challenge on their 1U CubeSat ENSO.
The first hint is in the beacon right now :slight_smile:

To cite them (from X @CSUM_F4KJX):

Starting soon, the beacon will transmit 4 GPS coordinates — can you find the hidden point based on these coordinates ?

Cheers!

  • ENSO (NORAD 58470)

manual decode using linux:

  1. download the .ogg file from your observation result
  2. convert into wav
    sox input.ogg output.wav
  3. decode using gr_satellites,
    gr_satellites 58470 --wavfile output.wav

example result:
→ Packet from 9k6 FSK downlink
