Mike, data modes with bandwidths of about 2.4 kHz have been in use on HF for at
least 13 years. RTTY/data and phone/image have separate subbands. Changing that
would be a major change. RM-11708 proposes a minor change to prevent the use of
much wider data bandwidths and more efficient use of the bandwidth now in use.
Why is that a bad thing?
W1AW does not operate under automatic control. There is a control operator on
duty at all times the station is in operation. Transmissions are made on
published frequencies and at published times, and have been for decades. If you
follow your logic to its natural conclusion then somebody could just shut down
the bulletin and code practice function by squatting on those frequencies.

Dave,
113 a 3 iv talks about compensation for the control Ops. That was not my
question.
My concern is with any station not just W1AW firing up on a specific frequency
without checking to see if it is busy. No where in the rule above does it say
that all the other rules can be ignored. Transmitting on a frequency without
checking if it is busy is contrary to all the
published operating guides by the ARRL and contrary to the FCC rules.
Where in the rules does it give any station the authority to fire up on any
frequency without checking?
The rule says you may pay your control op if you have to have a schedule and it
has to be published. It does not mean that the schedule must be followed at
all costs. The FCC has stated many times that no net, organization or
otherwise own or control any frequency unless they are using it. When I stop
using a frequency it if free to be used by the next person. If I am using a
frequency I should be able to continue to use that frequency until I am
finished.
Are you saying that there is a control operator on duty at all times when the
bulletins are being sent? I always thought it was an automated process. If
there was a control op in charge at the time of this issue why did he/she allow
the transmission on top of a frequency in use?
This behavior would be in violation of the rules would it not?
Any proposals could and should have moved the wideband transmissions into the
wideband area ie SSB and SSTV. The proposal could and should have set a much
lower limit on signals in the cw portions to something much less than 2.8khz.
Pactor 4 and winlink will take over our cw bands with transmissions much like
the W1AW broadcasts. No need to check if the frequencies are busy, just
transmit, wipe out the cw or rtty that was there and do whatever it is they do.
These wide band data modes can easily deal with narrow band noise which was
why the proposal moved them into the cw bands. They cannot deal with wide band
noise like SSB ans SSTV.
If W1AW does not have to check if a frequency is in use then why should anyone
else? These so called automated systems either ignore frequencies in use or
just don't care. There are many complaints about many of the other modes just
coming on and causing interference.

Mike,
The bulletin transmissions must conform to the published schedule in order to
comply with 97.113(a)(3)(iv). 18 MHz is problematic because the band is narrow,
but it provides excellent coverage.
2.8 kHz HF data signals are permitted now and have been in use for more than a
decade. What RM-11708 would do is to limit the bandwidth to that rather than to
continue the status quo, which allows much wider bandwidths.

Dave,
Apparently in the last few days it was reported that W1AW came up on
18.100 and started the Bulletin. Unfortunately, one of the W1AW/X
stations was on that frequency.
I have been going over the rules and I would like to understand why
W1AW does not check for a busy frequency prior to firing up. Where in
the FCC rules is this allowed. I am sure that I would be subject to a
pink slip if I decided to fire up on top of W1AW or face much peer
retribution wouldn't I?
Sadly if RM-11708 passes we will all be subject to 2.8khz signals
firing up on top of people using a frequency just like W1AW does.
Maybe you can explain the difference to me.
