Domenico and other interested folks,
Read what G3LTF has said about Galileo and 23cm EME:
He paints not quite so bad a picture as Bob and John do. If you think a
handful of "potential" ham satellite users are potentially effected, the
large (2nd most popular EME band, today) 23cm EME population are watching
this keenly. I have several thousand dollars invested in my future 23cm
EME station...and I will just been a medium size station. There several
>10m EME dishes operating in Europe...those are not cheap. I suspect Ham
radio on L-band will not go down without controversy and a significant
fight. Yes, I understand the multi-B$ industry "owns" the radio spectrum,
but I think this is gotten a bit hysterical and negative in view. I
suspect EME will survive on 23cm and perhaps satellite uplink use (with
At this point it is all speculation (even with engineering analysis). I am
glad the decision is to fly a mode-L Rx. I predict it will be usable in
the early years of Eagle (at least).
