I agree, Steinar. The principle we all must follow on amateur
frequencies is that they are SHARED frequencies, which means used on a
first-come-first server basis and anyone accidentally transmitting on an
ongoing QSO must also be capable of moving when asked, as well as being
able to check if the frequency is clear. Some will say that DX pileups
or contesters also do not share, but at the moment of transmission, the
frequency may appear to be clear. The interference is due to severe
overcrowding, and not intentionally trying to dominate a frequency. This
is much different from transmitting without any attempt to check at all.
Winmor, Winlink, and ALE all violate that time-honored principle, and so
did Propnet until they moved off the normal QSO frequencies.
Our FCC has set aside a set of frequencies on several bands for stations
that are automatically controlled to accomodate stations that do not
listen first, so those stations have no justifiable excuse to complain
about interference amongst themselves. They are lucky to have any place
at all to operate, and that space is far greater, in proportion to their
representation in the total ham population wishing to use the bands,
than would normally be allocated. Just because one group thinks THEIR
traffic is more important than other traffic does not give them a right
to dominate or claim exclusive or primary use of any frequency. This is
a primarily HOBBY, and not a "service" to others, and it is only on that
basis that we are permitted to keep the frequencies we have. In a true
emergency, ALL frequencies are available to emergency operators and all
others MUST give way, so even claiming to be essential for emergencies
does not convey any right of ownership of any of our shared frequencies.
To answer your question specifically, Winmor, if over 500 Hz wide, is
only allowed to operate in those automatic subbands. They are also
required to check that the frequency is clear before transmitting, even
in the automatic subbands, but that is not enforced because it is
basically unenforceable. You can see the result there - stations
regularly trample each other because there no practical means of
enforcing that they do not. Without rules, just imagine what the bands
would be like if powerful or special interest stations that do not
listen first were spread all over the bands. That almost happened a few
years ago until the FCC refused to implement the ARRL regulation by
bandwidth petition.
Unless we insist on maintaining and supporting the shared nature of our
bands, special interest groups that do not share will take over the
bands and others will have no place in which to operate for QSO's,
experimenting, contesting, DX chasing, etc., One problem with
traditional spread spectrum is that it is designed to be hard to
monitor, which therefore means hard to police, either by ourselves, or
by government agencies. However, since ROS can be monitored by third
parties, we hope that the FCC will amend the regulations to permit ROS
to be used on HF, but until that is done, we in this country have no
choice but to abide by the current regulations, even though they may
seem to be unfair.
Without any overall supervision, there will be anarchy, and with
arnarchy, chaos will soon follow. Rules help to prevent arnarchy and
chaos, and are not 100% effective, but are better than nothing.

Hi Skip
But why is a mode like WINMOR allowed in US? I know it is not SS , but
you can't monitor the traffic.
If I have not totally misunderstood, that is one of the criteria for
using a digi mode on the band.
Just a thought , but it seems that some part of the FCC rules are more
important to follow than others.

Thank you, Steinar, but there have been serious attempts to dominate
the HF bands with wideband modes for what is basically a private system
use, and the FCC acted to protect the bands from that abuse, so while it
is sad for us right now, what the FCC has done in the past has protected
all hams worldwide from such abuses, even if you do not realize it. I do
think ROS should be allowed, but until fully reviewed by the FCC, their
are correct in not allowing ROS to be used except on an experimental
basis. Believe me, there are much more dangerous fish in the sea!

I'm with you, Skip. While I appreciate the effort Jose put into this
mode, I
won't be using it on HF.
The article quoted as justification of the legality of ROS was
written by
the Italian developer of Chip64 who is not under the jurisdiction of the
FCC. The ARRL lists it only as a technical reference to the mode.
Since
the ARRL is NOT the regulatory agency, it really only matters what
shows up
in Part 97; and under Part 97, Chip64 is also illegal on HF in the US.

Thank you for your opinion, but need to be told to "calm down" as I
am not
excited! The FCC rules are plain and the description of ROS by the
author is
frequency hopping, whether within a phone signal bandwidth or not,
so that
identifies it as spread spectrum. I am sure the FCC rules were
intended to
prevent overly wide signals on HF using spread spectrum and
therefore they
only permit spread spectrum above 222 Mhz, where there is plenty of
room.
ROS is a really nice mode, but I will be using it only on 432 Mhz, in
accordance with our FCC regulations. Others under FCC jurisdiction are
welcome to use it at their own risk on HF.
The current FCC rules are also probably intended to allow FCC
monitoring
which is not possible with conventional spread spectrum, so I hope
the rules
can be changed for spread spectrum modes like ROS which can be
copied by
third parties, but until that happens, rules are rules, and we are
legally
obligated to abide by them.
