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.

You are correct.
Hams are prohibited from sending coded communications.

an aside I find it amusing that a memebr of NCI is explain this but Ron
Baker's statement is incorrect because it is incomplete he should have
type (caps mine) "Hams are prohibited from sending SECRECTLY coded
communications."

Morse Encoded OOKed CW is not asecert the same rule allows PSK #! the
code is known, there was a discusion last July i think on RRAP to the
effect that Likely a coded messge by some PGP could be send over ARS if
the loctcation of all the keys were tranmited in the clear. it was
alsoagreed that the FCC would likely fght that battle out

I beg forgiveness.
Strike 'coded' and insert 'encrypted'.

You are not even supposed to speak in code. Yet somehow, speaking in a
foreign language on repeaters is considered acceptable, though not by
me.

There was a period when FCC considered ASCII to be a "secret code", and
prohibited its on-air use by hams.

Seriously.
