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!
