[amsat-bb] Es’hail mind storm. !!

[Jerry Buxton]

Hi Dave, Nader,

A CubeSat Converter is certainly an interesting thought.  In addition to
the challenges (that's the hip cop-out from saying "problem" these days)
that you noted, I'm thinking that the ConverterSat would also:

Have to be in the footprint of Es'hail
So as a converter even only in the footprint for stations in the
footprint but w/o the S and X equipment, it would only offer a 10-20
minute window to Es'hail the usual 3-6 times per day
In trying to extend the footprint, it would need to be of a pretty high
altitude itself in order to extend the footprint by much
Being on the edge of the Es'hail footprint in order to extend it,
requires more power/gain/pointing to connect with Es'hail

But I guess these are more "usefulness" challenges than the RF
challenges of acting as the converter you have listed.
It gave me thoughts about GOLF-TEE trying to bridge the gap, but would
have design implications as you noted that at least wouldn't be possible
in our current timeline.
