Amsat-DL international team successfully transmitted and received 
signals via Venus on 25-03-2009 at 10:38 utc.

The signal received was about 0.3 dB under bad interference from WLAN 
and bad weather in Bochum.

The transmitter was about 6 kW CW on 2.4 GHz .
The transmitter used a magnetron that has been locked to rubidium and 
for the first time SSB quality was achieved making it possible to use 
this transmitter for P5A Amsat-DL mission to Mars.
The use of a magnetron for this purpose was possible thanks to a new 
Amsat-DL developed modulator that enables a magnetron to be used for 
narrow band operation.

With this transmitter Amsat-DL is ready to start the next step in the 
Mars mission and prepare the spacecraft.
