Subject: Digital Modes, Via Sound Card
I'm sure ithe subject has been posted here before, so I am hoping
someone can help me.
My father is interested in decoding digital modes from his HF receiver.
Is there software that allows feeding the audio into the sound card of
his computer and decoding the various digital modes? If so where can I
find it?

Subject: DOS-based PACTOR program?
You may want to try XPCOM by Gary Johnson. XPCOM is a DOS program that
supports PK-232 (and I think it supports PACTOR mode of PK232). Apparently,
the trial version is fully functional (ie not crippleware)
I don't have a URL for XPCOM but do a search for XPWARE and you will find it

A 'known bug':
MacOS 9 causes the scrollbar in NET/Mac's online-help to disappear...
Dick KD5VU reports:
A work around that seems to work is to get NET/Mac HELP active, select a
visible item, then do about 10 NEXT-clicks and stop on the 'addmenu Command'.
You can then access the topics with a scroll bar
Happy New Year!

Subject: Scrambler
These aren't legal for amateur radio (at least here in the U.S.).
Compression is allowed. Encryption is NOT.

There are a number of points that need addressing here.
1. The originator of the thread did not ask for knowledge, he asked for a
software scrambler (note: he referred to "them"). He wanted software, not
knowledge; they are two different things.
2. The terms scrambling and encryption, regardless of certain technical
nuances, are perceived to be the same thing by the general public, and for
that matter, many hams. Even a cursory search of the web will turn up
hundreds, if not thousands, of references in the form of "scrambling
(encryption)", "encryption (scrambling)", and similar phraseology. This is
done not just by individuals, but by governments and security firms on their
official web sites.
3. For ham radio transmissions, US law prohibits the use of encryption and
various other schemes that mask the meaning of the traffic. Here is the
specific section of the CFR:
§97.113 Prohibited transmissions.
