Interesting subject. Last time I get Kuhne 10GHz transverter but up to now I had no chance to do any QSO... Not so many crazy people are around. Here in Europe I have access to QO 100 satellite (2.4Ghz uplink, 10GHz downlink) so I decided to build upconverter by myself starting microwave journey.. very interesting. I think we need more satellites to make microwave activities more popular.
