Hi Bob, N4HY
You said"
What will happen if the Galileo goes up is that no European airport will allow a commercial jetliner to land without the Galileo system. This will inevitably lead to this basic system being in world wide use for navigational purposes.
Does this imply that all 23 cm EME stations have to be moved away from 1296 MHz ?

Domenico and other interested folks,
Read what G3LTF has said about Galileo and 23cm EME: http://www.batc.org.uk/club_stuff/G3LTF_Galileo.pdf
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 some compromise).
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). 73's, Ed - KL7UW ========================================= http://www.qsl.net/al7eb - BP40iq 144-EME: FT-847, mgf-1801/1402, 4xM2-xpol-20, 170w 432-EME: FT-847, mgf-1402, 1x21-ele (18.6 dBi), 60w =========================================
