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.

P3-D Telemetry Beacons (IHU)

BEACON General Beacon (GB) Middle Beacon (MB) Engineering Beacon (EB)
2 m none 145.898 MHz none
70cm 435.438 MHz 435.588 MHz 435.838 MHz
13cm(1) 2400.188 MHz 2400.338 MHz 2400.588 MHz
13cm(2) 2401.173 MHz 2401.323 MHz 2401.573 MHz
3cm 10450.975 MHz 10451.125 MHz 10451.375 MHz
1.5cm 24047.885 MHz 24048.035 MHz 24048.285 MHz

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.
