Hello David,
A very sound suggestion.with which I agree 200%.
It appears that Eagle is languishing in inactivity and Intelsat needs
multi-millions which I don't see in the coffers for some time, if ever..
Pardon my pessimism, but I don't see AMSAT-NA launching a satellite,
using the current game plan, for at least 5 years, if then.
Your approach puts the "horse before the cart" so to speak and offers
the best chance of launching an new satellite within 2 years, if that is
what the satellite user folks want, and I sense they do.
Speaking of the (this time) "cart before the horse", AMSAT-NA has now
starting an ACP ground station initiative without knowing what the
satellite looks like it will have to work with.
I see your suggestion as positive and constructive and not one to be
construed as negative and counter productive and thanks for putting it
forward. I wonder what the rest of the reflector readers think?
Regards...Bill - N6GHz

Isn't the story very simple regarding the critical step of launching
P3E: they're looking for an affordable ride, and there are none on the
horizon?
I assume it is very hard to enter into negotiations looking for a
cut-rate on a launch while publicly naming the party you are
negotiating with. If I were that party, the first thing I'd insist is
that there be no mention until a deal is reached, because my
organization could end up looking like bad guys for even entertaining
the idea.
On the technical side of P3E, I think we've been reasonably
well-informed, but then I don't think AMSAT-DL is obliged to report in
English any more than AMSAT-NA is obliged to publish its reports in
Japanese and German because significant donors came from those
countries. We can always get by with online translators if we don't
know German. It works pretty well; I can show you how.
73, Bruce

I decoded today, 21:39:00UTC 31May2008, QuakeSat KISS signal
after a long time using online_kiss.exe and kissdump.exe programs.
