Ok, I ran S Band on AO-40 as well; my home, radio shack, and neighborhood are covered with 2.4Gig stuff. The ONLY interference I ever received was in the form of Very short burst (pops) which any noise blanker was extreamly effective at removing.
The 5Gig band will be in the same shape as S Band is today. I simply don’t buy into the Interference argument. 73's DE K7ZT, Joe ---- "Félim Doyle M3HIM" Felim.M3HIM@ntlworld.com wrote:

I love these messages; I really can't get enough of them. They really brighten my day. If Luc and AMSAT would bind these into a book, I'd buy it. I'd call it
"The
AMSAT Anthology of Conspiracy".
Luc, keep on doing what you are doing.

Disappointed to find out that there will not be an S band downlink on Eagle
Will there be an S band downlink on the P3E bird???
Sure hate having to fork over more money each time a new satellite
goes
up
because previous up/downlinks are not being used anymore....makes me
wish
for more mode A LEO birds (grin)
73, Joe W2KJAnother bad move by AMSAT-NA... I don't know if they look at their
famous
survey about their members opinions here? Probably not could be some one will wake up from lethargy at the next symposium and voices opinions about the maintaining of mode S.
If AMSAT-NA is building sats in close circle they just have to openly admitted it even if admission is not a very spoken word they can at least give some explanations on their facts who leads them to scrap mode S?
Interference? even if they wants to go higher at the time eagle will be
in
space the higher frequencies will be as crowded as 2.4 actually. We actually see some decreased in 2.4 ghz apparatus as the public always want the most recent goodies even FRS/GMRS are
moving
to 5.2 ghz.
Suggestion: At the next AMSAT-NA 2006 Space Symposium it will
appropriate
to voices opinions to the BOD asking them to maintain as planned the mode S.
Just to pointed out on a 2005 AMSAT-NA Dayton Hamvention Jim Sanford WB4GCS made a presentation on eagle project and he said i quote " S band will be our bread and butter
on
the downlink" a prototype of L/S and C/S where planned for the 2005 Symposium at that time.
He also mention that the C/C project in on a bleeding edge technology (read experimental) and they where not too sure if they will even be able to make it.
Why the C/C band project? he let go this " this will permit some folks
to
use it from their balcony" the cat goes out the bag AGAIN the same ECHO mindings are resurecting...The guy with an HT will be able to make it without using a huge antenna!
We will never be able to get rid of this obsession and you know now why they want to move up? The guy who live on a balcony is living in an apartment complex where S band in unusable. Here is why the C/C project come up. How many actual sat operator are living in apartments? the majority of some of them?
Here is the whole logics behind this mode S scrapping. If you read a bit behind the lines you will see he speak about P3E where mode S will be present and he confirm some collaboration between both teams. He also say some of the Eagle builders are funding their own project. From this since 2005 we can only see the builders behind the C/C project pushing so hard to a point to get the money previously intended for the 2 S mode TX redirected to their C/C project.
Who is driving AMSAT-NA an hollow BOD? an hollow president? Or a third builders manipulating wing who blackmail the BOD?
None of them? I let the conclusion yours!
P.S.To the BOD its not the best way to attract new members or convince those who leave to rejoin!
"-" The medium is the message...The content is the audience...;)

Count me in too, in favor of S-band downlink. I read the engineering argument which predicts total chaos on 2.4 ghz, and also the engineering analysis that shows that bumble bees can't fly. To a first order approximation, both are probably correct. Yet bees do fly, and we will be able to make good use of 2.4 ghz on our satellites.
I also fear that our abandonment of S-band will just make things worse for those lobbying for our spectrum. Until AO-40's "event", I had only mild interest in 2.4 ghz. Now I have an effective 2.4 ghz receive station. It's not optimal by any means, but having a new HEO bird on the band will give me the incentive to improve its performance.
Bring us S-band!
