tried to work out any of the numbers, it's just some   idle
musing.  It has occurred to me that we are in the midst of a
minor revolution   in amateur radio (which will undoubtedly be
followed by a more major   revolution).   In the last 10 years,
cheap computing and sound cards   have caused a great deal of
experimentation with "sound card   modes" (the minor
revolution), and will ultimately lead to the major   revolution
(widespread use of SDR).   We have a kind of flexibility   that
we couldn't think of even a few years ago, a flexibility that we
gain from Moore's law.  So here's an idea: let's do away with
the need for Doppler correction   entirely.  It's not like we
don't have decent orbital elements for the   satellites that we
use.   It's not like our ground stations don't have   accurate
timing information available to th
