The REAL future of S-Band (was "Special AMSAT dinner")
Actually, I suspect that 3 years from now, we will see 2.4 GHz thinning out, as WiFi users migrate to the new latest-and-greatest products at 5.8 or higher. We all know that the lifespan of your typical computer "widget" is less than 5 years, and usually closer to 3. Already, stores like Best Buy and Circuit City are carrying way more 5.8 cordless phones than 2.4's... and when was the last time you saw a 900 MHz version? It wasn't that long ago that THEY were the cutting edge cordless!
The same thing will happen with WiFi: all the new laptops and PDA's will come with the higher frequency cards, and users will be forced to migrate upward. You can take that to the bank! So put S-band on Eagle - I predict that it'll be wide open in 10 years, NOT a sewer.

Three years from now when we have to suffer from a new round of comlaints about 2.4 GHz QRM interfering with the P3E Sband downlink, we could have a special AMSAT dinner. The main entrée might be crow.

Hi all: Where can I get some verbose shuttle keps?

Hi George,
I don't believe anyone except AMSAT routinely generates verbose keps, but you should be able to decode them from the keps from Space-Track. Here is the key: http://www.amsat.org/amsat-new/information/faqs/kepformats.php

It turns out that NASA's web page for shuttle keps DOES have verbose format keps on it.
Go to http://www.amsat.org/amsat-new/tools/keps.php and follow the link for shuttle elements.
Here's the direct link: http://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/...

and yes, this is off-topic for AMSAT-BB since there's no amateur radio connection.
I didn't know that! Thanks Paul!

I disagree. Sure, eveyrthing is going up because 2.4 is overcrowded. But as soon as the higher bands get satruated, market forces will see a return to whatever band is still viable. It 2.4 thins out, then more future consumer devices will just come back in...
No way will a "license free band" ever become empty or abandoned (yes, 49 MHz may have, but it has so little bandwdith...that no one wants it? Bob
