Info for Radio Amateurs

We encourage anyone with a radio capable of receiving in the S-band (2,4GHz) to listen for DTUsat-2 beacons.

The preliminary TLE of the Dnepr launch is:

Beacon frequency: 2.401,835 MHz (2,401835 GHz)

Beacons are transmitted by two different subsystems onboard: COM (the radio) and OBC (the onboard computer). COM and OBC transmits every 60 seconds with a phase shift of 30 seconds. This means a beacon is transmitted every 30 seconds alternating between COM and OBC.

The COM beacon is Morse encoded and can be decoded by ear, the OBC beacon is FSK encoded.

The sound quality of the recieved beacon depends on the link budget. Below we've made examples of increasingly lower signal to ratio, ie. more noise less signal. With these it's possible to do a little rehearsal before the pass begins.
