Len:

You are right, they do look like a little like a dutch boy with his
finger stuck in a dyke.

The only part which amazes me is that they fail to see or feel the
flood waters which have already risen above their heads. This is all
going on and no law, person or group even slows it a bit. Progress
has a life of it owns, it waits for no man, no group, no law...

Funny thing is, amateur radio was implemented with the idea these
"experimenters" would give back to the community in advances in the
field--somewhere this got totally reversed and now they cry for more
laws and regulations to halt progress--now I have never seen a better
display of insanity!

But, somehow they think they can argue this as a "service" to their
fellow citizens. Krist, the egyptian high priests who held their whole
nation hostage were more progressive! At least they made good durable
mummies...

If one ever gets serious about using HF for video, and HS data
transmission, this:
http://www.thiecom.de/english/?g313i/
is an excellent investment. The digital signal can be pulled
directly
off the PCI bus in the computer and fed to software. This company
supplies the software framework for just about anything you can
imagine, if you know how to code or know someone who does--the sky
is
the limit...

John, lots of us know of data compression and maybe a few
radio amateurs will acknowledge the elegant work of Claude
Elwood Shannon back in 1947. But, that is really NOT the
issue in here. Status quondam is the issue.

Even worse, it is the stubborn, hidebound, refusal to break
out of the antiquated standards and practices of pre-WW2
times to meld with the rest of the world of modern times.

The only "code" allowed by these dino-denizens of the past
is MORSE code. Anything else, such as (horrors) "source code"
is nothing but a bunch of NOPs with an occasional HCF. Those
that have bought into it and passed the morse test will do
more flaunting of their morsemanship than a convention of
actors in Hollywood bragging of their credits. [they have
no Variety]

Using "examples" of half-GigaByte files "expected to be sent
over little teeny narrowbanded enclaves of spectrum is itself
an example of their non-thinking, non-research, non-educated
attempts to stall any sort of progress. They can't do the
numbers (despite flaunting of non-amateur titles), won't
bother with looking up things, everything-is-just-fine-as-
when-they-first-joined-long-ago-thankyouverymuch.

Case in point: DRM (Digital Radio Mondial). Digitized audio
on HF, now being transmitted (over two dozen programs now
listed), capable of overcoming the selective fading common
to the "wow" heard so many times on analog BC, tested for over
four years on HF. High-quality audio fitting within a 12 KHz
bandwidth, an occupancy no greater than present-day audio on
broadcast. DRM may not be the technical best, but it IS a
WORKING system. It works on LF, MF, HF, VHF. By test.

A few years ago in here a bunch of narrowband, narrowthinker
olde-fahrts exclaimed and exclaimed that "it won't work!"
That was during the successful testing phase of DRM. The
same group also decried GMDSS as "unworkable!" even though
the maritime community had already researched and tested it
and approved it worldwide. Morse code on 500 KHz MUST continue
they said, ignoring what the SOLAS folks had already determined.

The general idea of DRM, scaled for 2.5 KHz voice-only audio
bandwidths is eminently possible on HF. Effects of selective
fading on HF will be less than the wider bandwidth of broadcast
audio. Further, since it already IS in digital form, it is
applicable to direct-sequence spreading and the ability to put
many signals on a given band without any mutual interference.
The narrowband, narrowthink amateurs will have none of that.
They will yank out the "12 KHz bandwidth" of DRM and shout it
is way too broad for amateur use...while they totally ignore
the scaling that can (and sometimes is) done for narrower band
audio.

The narrowband, narrowthink status quo-ists will demand "already-
done, tested, approved, on-the-market" products to "demonstrate"
that it will work. [they have in the past in here] :-) In
other words, "don't bother me until I see the ads in QST" kind
of mentality which seems to have become standard on the USA
amateur scene. The narrowband, narrowthink hams are content
with their narrow slices of spectrum, the bands appropriately
sliced up into "bandplan" segments like separator boards in a
sandbox. They have achieved Titles in their federal authority
and haughtily parade that to play in the "nicer" parts of the
sandbox.

Analog-ONLY is the cry of the narrowband narrowthink group.
Keep it SIMPLE so that the most theory they need is just
Ohm's Law of Resistance. The have resistance to anything more
complex. Stay with the gamesmanship, enter the contests for
"radiosport" and win nice certificates (suitable for framing).
Forget the exploring of the new, trying out something different.
Too HARD to think. Follow preset rules and fill in the blanks.
Big Brother in the NE will protect them. Offshore designers
and makers will provide they radio toys, all their bells and
whistles. :-(

"Shannon's Law?" Ain't in Part 97. Fergit it...
