Reception of Mars-Express and Odyssey



Based on the explanation given by G3RUH a group of hamradio operators at
DL0SHF, who are Per, DK7LJ, Klaus, DF5DU, Norbert, DC6UW Roland DF3LZ and
Martin and Nils have also succeeded to receive Mars-Express and Odyssey
using a 7 m dish.
The equipment was: 10 GHz preamp, 30 m Ecoflex10 cable, few filters,
30 db linear amplifier Circulator, broadband mixer an R9000 rx. The LO
frequency was supplied by an signal generator HP8672 and applied to the
circulator.
For more information with some pictures please visit
http://www.lernnetz-sh.de/satellit/mars/index.htm which is in German
however. There are also some useful links.
They reported that they received Odyssey for a whole orbit and could
clearly watch the doppler.
