The fact that a protocol is proprietary or patented does not make it
illegal on the amateur bands; I'm not sure where you got that idea. If you
re-read the regulations you will note that only encrypted communications or
those whose meanings are intentionally obscured are prohibited. The fact
that the FCC (or anyone else) can't get the necessary equipment for free is
not an issue.

Maybe Canadian rules are different?

There is enough freely available public information on PACTOR II
for me to build a decoder. There is not enough freely available
public information on CW for *some people* to build a decoder.
It is still a simple build or buy decision. A CW transceiver is
easy to build. An SSB transceiver is a little harder to build.
A PACTOR II decoder is harder yet but certainly not impossible.
> And therefore illegal on any amateur band?
Can the FCC freely decode it? Yes, therefore it is not illegal
in the USA. I'm not familiar with Canadian amateur rules.

FCC Rules 97.309(a)(4) "An amateur station transmitting a RTTY or data
emission using a digital code specified in this paragraph may use any
techique whose technical characteristics have been documented
publicly, such as CLOVER, G-TOR, or PacTOR, for the purpose of
facilitating communications."
So, FCC rules specifically authorize the PacTOR mode. Apparently the
technique is documented sufficiently to satisfy the FCC.
The FCC appears to look at the "code" as a separate issue from the
"technique". If the individual characters inside the protocol packet
are ASCII or are derived from ASCII (as done with compression) *and*
are not intended to be encription then the code is ASCII. CLOVER,
G-TOR, PacTOR, and Packet are all legally ASCII codes regardless of
the different techniques (protocols) used.

Forget about it, it's legal, now move on. Quit wasting your
energy. There is no case for it being illegal in most 1st and
