Satdump & Syracuse 3A/B X Band beacons

  • Syracuse 3A, 49.0°E [incl] is on 7720.0MHz LHCP

    Syracuse 3B, 5.2° W is on 7705.0MHz LHCP

    These are screenshots from Satdump demodulating the beacons. The polariser was set for 8.4GHz RHCP so not good for 7.5GHz LH. 3A is close to the trees hence the lower signal there. The output is an encrypted binary stream.
