Tony,

It was probably mentioned in some of the Amsat Journals, but it was 
determined that the original "C-C Rider" project (5.6 GHz up & down) 
was not feasible to build.  Thus discussion ensued that ended up with 
using 3.5 GHz as a downlink.  It is much easier to build full duplex 
filters for the wider freq. separation.

Although 3.4 Ghz is not a world-wide ham allocation, anyone can 
receive there.  The Flyer probably needs an update.  I cannot answer 
on that.  All Amsat is done by volunteer work.  I suspect some tasks 
are begging some help!

I would like a little more info on Eagle and P4, as well.  Likewise 
news from Amsat-DL on P3E would be nice.

I think most of us appreciate that a lot of work goes into getting 
these new Heo's into orbit.  Most of use are armchair observers!
