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!
