I'm not a ham and don't know the rules but it might be illegal for them
to use encryption. If this is not true I'm sure someone will correct my
speculation.
We're probably talking government and military data comms. In that case,
it would be essential to encrypt it. Private services have moved to
satellite for the most part. The military needs the mobility that
shortwave provides-you can't haul a satellite dish around Baghdad, even
a small one. Private organizations don't, so they use satellite.
