Sorry Howard. I think many of us have
been saying all along that we need INTERNATIONAL band plans, at least, I been
saying that for several years. But if anyone thinks they can be voluntary,
they have their eyes closed ....er..... their ears anyway. The sub
bands here in the states work, only to the point that there are regulations, no
matter that the FCC often seems to ignore them. You speak of our signals not getting out of CONUS,
sorry but that works the other way around. I hear ALL sorts of signals ALL
over the band, from countries that have esentially NO rules other than staying
within the broad sector of the assigned amateur frequencies. SSB in the
lower portions of all bands, RTTY and Data all ovr SSB, Image on top of PSK,
etc. etc.doesnt show me that the rest of the world lives by "nice".
Setting our own rules doesnt affect them at all, other than the fact we may
intefere with our mode on top of theirs (thus the need for internatonal
rules).
There will be no world wide bandplan that works, unless its under a rule of
law. None do now, and none will, given human nature. And I also dont
see anywhere in this discussion where anyone is saying the we need the
government to make sure we dont try new modes, methods, etc. We simply
need them to insure new things dont harm the old.

As usual what you write makes too much
sense...
Be sure to put on your asbestos
suit....
Yes ... we need a world wide bandplan.. without
any glacial government regulation...
And most of the world will ultimately go that
way...like Canada and Australia....
But the USA is a special place... our radio waves
always stay within our borders and we do not hear anything from the rest of
the world...
so they are going to tell you that we need the
government to make sure that we do not try anything new...

Hi Steve,
Question: Why is Olivia
manual keyboarding in the 14100-14112kHz USA
Automatic Sub-Band? Answer: After doing some research into the
Olivia 14MHz disaster, I found the reason Olivia users are camping out
above 14101kHz. The Olivia bandwidth default is 1kHz. Olivia was
originally designed and started in Europe. The IARU Region 1 Bandplan
(Europe/Africa/MidEast), and some European radio rules dictate 500Hz
maximum bandwidth below 14099kHz and 2.7kHz bandwidth above 14101kHz.
Also, the bandplan details "digimode" between 14101kHz and 14112kHz.
Hence, to use Olivia, european stations must camp between above 14101kHz
and below 14112kHz on 20 metres. A very similar thing happened with MT63
on 14109.5kHz some years ago, but MT63 never reached the fad status
of Olivia, and MT63 use has decreased to near zero over the years.
The overlay of USA radio regulations forming the 97.221 sub-band
at 14101kHz to 14112kHz falls flat when you consider that
radio ionospheric propagation knows know political or IARU
regional boundaries... and the IARU bandplanners of different regions
and nations often don't agree or exist in the same radio
environment.
In 2005, as you probably know, the huge increase in
Olivia keyboarding activity camping out around 14107.5kHz caused the ALE
network to move up from where it had been for the past 5 years
(14107.5kHz). The ALE network's move took a great effort on the part of
hundreds of ALE operators to re-program their only 14MHz ALE
data/sounding channel. The ALE network would have moved earlier, due to
the massive Olivia QRM, but generally speaking, it requires about 6
months notice, and at least 6 months for changes in the amateur ALE
channels to propagate among all operators (some ALE controllers require
manual entry or special cabling, fill files, and setups for programming).
The ALE net moved up as far as it could, to 14109.5kHz and then we
actively put the Olivia community on notice that we simply could not move
any higher than that. (By the way, I'm an Olivia operator,
too.)
The sub-bands among the regions and nations are
constantly conflicting, which will lead to even more Olivia-like
mode-based and content-based bandplan conflicts. At the same time, we
also are seeing a huge change in the nature of how we communicate on HF.
Take a listen between 14230 and 14240 sometime and you will see a similar
situation in progress.
The fact is, with the growth of high speed
robust HF digital communications technology, amateur radio is seeing
changes from an older bandwidth-centric model to the use of a newer
time-centric model for data exchange. This means that the future will see
more time-sharing of frequencies on a rapidly interactive and dynamic
basis than there has been in the past. This fact is part of what is
causing the "growing pains" and misunderstanding among the rank and file
for bandwidth-based spectrum management in USA. Most hams are familiar
and thus comfortable with the operational aspects of the slow
information exchange model such as voice, CW, and realtime keyboarding.
More frequency space is needed for wider bandwidth signals in the
IARU Region 1 bandplans on 14MHz. More space is also need for
wider bandwidth automatic operation in USA. For several years, I've
been advocating a 500Hz/3kHz bandwidth sub-band separation at or
about 14050kHz or 14075kHz. I don't believe a sub-band for 200Hz
bandwidth is beneficial at all, or practical in the sense that most hams
could not live with strong and weak CW or even PSK signals separated
by 200Hz. I have never advocated any HF sub-bands for
confining automatic, semi-automatic, or remote operations. I see there is
no longer a clear distinction between what "automation" is and what it
is not. Automation in some shape or form is becoming more commonplace
in many of the new methods of HF communication. For instance, SSTV
and Digital Voice use automatic methods for station ID, handshaking,
and even automatic start-up and responses. If we continue to
have governmental radio rules confining automation in USA and elsewhere,
it will continue to conflict with actual use of communication
technology on the air by hams. It will also confine and suppress hams who
lives within the jurisdictions of these automatic rules from moving
forward with the rest of the world's hams who are not confined by
antiquated anti-automation rules.
Now, after a lot of discourse
with hams from all different viewpoints, I now believe the best thing for
ham radio is to have no sub-bands at all in radio regulatory rules. No
bandwidth sub-bands. No automatic sub-bands. No license class sub-bands.
Instead, all sub-bands should be flexible and handled in the IARU Region
bandplans and national IARU society bandplans. It is too difficult to
change governmental radio regulations.
The Olivia 14MHz disaster
is one case in point... most USA Olivia users are oblivious to the fact
that they are operating in the automatic band.
The 7100kHz to
7105kHz USA automatic sub-band disaster is another case in point... there
is a shortwave AM broadcast station there!
