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!

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 

The 5Gig band will be in the same shape as S Band is today.  I simply 
don’t buy into the
Interference argument.
