Zdenek OK1DFC is building a 47GHz EME setup. His progress you can follow on his webpages.
Very interesting is to see RX performance of the system and RX/TX switch. We hope, soon we will see also a TX test. How Zdenek wrote, 10W SSPA for 47GHz is not cheap but we believe he will find some solution soon.
