Yeh!  Well, certainly too late to turn around this project, I think.  I
wonder what kind of orbit Echo will have...similar to the RS sats?
Operating mode-B thru a fast moving LEO may not be quite the fun that
AO-10/13 provided.  I would suggest a medium orbit mode-A/B bird...NO
REASON someone other than Amsat-NA cannot build one!  Certainly if done in
a cooperative manner with Amsat they would be willing to help with finding
a "ride"!  I wonder if any of the Russian engineers are still around that
built the RS birds?

I agree with prefering a linear translator vs. FM birds...but there are a
bunch of devotees to the later...sooo they will be happy (I hope).

my 2-cents

I'm hoping for a mode-SX bird, frankly...whistling in the breeze!
