Official Transponder Frequency Bandplan for P3-D

last revised on 30. January 2001

After several iterations and as a result of intensive research and discussions with all involved transponder builders, the P3-D Project Manager Dr. Karl Meinzer, DJ4ZC gave his final OK to the P3-D Transponder frequencies.

They have been carefully selected to minimize mutual interferences with other satellite projects and are also coordinated with IARU bandplans by the P3-D Frequency Coordinator, Freddy de Guchteneire, ON6UG, with the help of Peter Guelzow, DB2OS and Werner Haas DJ5KQ.

Beacon Frequencies have been measured before launch at Kourou and may change due to
aging, vibrations or temperature. 2-m-MB and 13-cm(2)-MB have already been measured in orbit.

Remarks:

All Receivers are inverting!
Telemetry Beacons are for command purposes and are modulated in 400 Bit/s BPSK, AMSAT format.
The MB can be switched between IHU-1 or IHU-2 telemetry.
