Hi,

Sometimes when I'm runing in stations with my grundig-fr200 radio I hear
something that sounds like teletype or really fast morse code. what is this?

Most likely RTTY or some other digital mode. If your radio receives SSB, you
ought to try and decode it with some of these software RTTY readers out
there.

Could be WEFAX, FAX, RTTY, SSTV, PACTOR, NAVTEX, some packet-based FSK
mode etc. You don't give us much to narrow it down.

Sometimes they intersperse CW ID's in among the deedle-deedles.

Single Side Band mode is a modulated signal without the AM carrier. You
usually don't want a carrier in the way when trying to use most data modes:

Except for the amateur radio bands, there is very very little stuff
that sounds like teletype that is decodable these days. Most of what
you hear is synchronous and probably encrypted.

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.

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.

When webtv first came out,it was illegal to transport a webtv unit to
any foreign countries because of 128 bit encryption.Look it up.

Heck,better than that,,, just invent some kind of a language nobody has

Anybody remember the fuss over PGP (Pretty Good Privacy), a freeware

encryption would fall into the hands of our enemies. It never caught on,
and the NSA likely cracked the code, so they stopped making a fuss about
it and now nobody remembers it.

I have always been suspicious since the time MIT (?) said, "you can't use
this version of it, but you can use this other version which is exactly
like the other version in every respect." Somehow I never believed the new
version was like the old version in every respect.
