We have kept Eagle satellite alive. The lab at U. Md. ES is being built out and we are going ahead with the structure. We helped fund the completion of P3E with our international partners and stepped up our efforts to finish the IHU-3 for them (and us.
The Eagle satellite structure build out is funded and slated for completion in 2008.
We are really going to try to get P3E a ride on Intelsat to balance against the other offers to see what is best for AMSAT-DL and us.
Stefan's analysis is correct. Any one geostationary bird can cover roughly a third of the earth.

All together they will give us the full package of worldwide DX via satellite and reliable high power communication in the Americas.

Nate, you are kidding, of course!
Yes, thus the " :-) ". Definitely meant as a joke.
Just poking a little fun at this -- a fixed bird is going to be very popular. Maybe sometimes "too" popular.
It was meant to come out with a tone something like the phrase: "Visualize Whirled Peas!".
Kinda like a new restaurant opening in your neighborhood, you probably don't want to be there on "opening night" if you're the type that likes to avoid crowds. (GRIN)

Thanks Bob.
It was great meeeting you in Pittsburgh and you have my full support for your ideas and initatives. Folks like you keep things moving.

I just ordered a newish LS-10a for my forthcoming amp, but I found one on QTH.com I thought I'd share. I don't know the guy from Adam, but it looks like a good deal to me. Caveat Emptor.
F/S Astron 28VDC Power Supply New. New Astron 28VDC Power supply. this is the Good for 12.5 Amps Continuous or 15 AMPS ICS. This is a switching power supply so it light and is about 5
pounds. $50.00 Plus Shipping. ASTRON Model SLS-15

AO-16 has been completely down for a while.

Hi Robert (N4HY)
I have been reading all the info on the BB about what appears to be a Geo syncronous amateur system supported by a commercial bird. Obviously you and others have done much work to understand this scheme in order to develop support for it. My problem is I do not have enough to really handle this issue as a Amsat Coordinator and was not able to attend the symposium. Being an uninformed Amsat Coordinator is not healthy for Amsat.
Is a system level proposal for this new Phase 4 going to be provided with sufficient numbers to allow membership evaluation before any impact on the Eagle system effort is considered acceptable. A question that needs an answer as I have already been asked.
Will an analysis of the effects on the HEO DXCC desires of the membership as to the effect of a stationary fixed aperture antenna pattern in Geo versus a moving satellite location fixed aperture antenna system not in Geo. To include the need to use high squint angles and power levels required on both ends of this sort of link budget.
Sorry I did not attend the symposium.

if its an AMSAT-NA project and money then I hope it is over the Americas!!! Think of the possibilities ... WAS, worked all US Counties (by Sat), worked all grids, worked all Canadian provinces, etc. Probably could even do it all MOBILE too, if one wanted to.
