The asymmetric propagation case is impractical to address, whether
the stations involved are attended or unattended; fortunately, its
not common. The case we can address is that of the unattended station

I agree that the regulations of which emission types can appear where
and at what baud rates has outlived its usefulness and needs to go.
As to all the intricacies and arcana, and why the FCC has gotten so much
of it so very wrong, I think that many forum members may be missing the
larger message

Well, I was aware of SCAMP, but maybe not well informed about the results.
I have never seen it in action, as I was not one of the beta testers.
Nevertheless, it is a formidable task, and I know that Rick did work
hard on it.
But as SCAMP has not been in public distribution and not relea

Not defending a wide mode...but its all in your prespective.
If I consider a 6-8 KHz wide mode a "wide mode", then a 2-3 KHz wide mode could
be considered a narrow mode.
There are amateur radio operators in the world who do consider a 2-3 KHz mode a
narrow mode and wide modes as being
I can't disagree with your comment. But, if you can't completely prevent it,
at least minimize it to the maximum extent possible.

I had also meant to mention that MT-63 is the most popular PCSDM FEC

Yes...there is more leeway on SHARES and MARS because they are not controlled
by the FCC. But other NGOs are and they can for the most part only use
USB...no other mode.
Thus for the NGOs to use other modes, they must rely on the ham bands where
their operators can use these data modes.

Hi Walt,
SHARES, is VOICE, PACTOR I and ALE AMD at this time.
MARS is using just about every FEC/ARQ protocol common in the U.S. In
MARS CW, it long ago was obsoleted. RTTY has not officially been
obsoleted, but is all but gone. In MARS AMTOR/SITOR is still seeing
use, mostly in FEC, but fadi

This is a sane idea and a good operating practice...are we (hams) suppose to be

Well with the old SkipNet, the ARRL submitted/requested an STA and one was
granted for one frequency on 20M, one on 40M and I think one on 80M. Which
didn't keep someone not listed in the STA from using the frequency but rather
making all the SkipNet stations stay on the "assigned" frequencies.

The FCC needs to attend some "Keep It Simple Servant" a.k.a. KISS

Pactor 3 is not classified as a narrowband mode. It is a fairly wideband

A big problem I have with the request is the classification of pactor
3 as a "narrowband" data mode. I recently found some new documents
that show the necessary bandwidth of this mode as 2K40J2D, i.e. 2.4
kHz. To me, this sounds more like a definition of wideband,
