Since an RM has been assigned to the ARRL's petition, I believe the
best chance for success now is to comment on that petition by saying
that removing the symbol limit is a good idea. *However* since, in
setting the current symbol rates the Commission recognized that the
majority of amateur wanted bandwidths "compatible with those of
traditional radioteleprinter modes" the appropriate action is to
replace the language of 97.307 with a *500 Hz* occupied bandwidth
*not* 2.8 KHz as proposed by ARRL.
In support of the 500 Hz standard, one can cite that the most common
HF "RTTY, data" modes are RTTY, PSK31, JT65A, JT9, WSPR and QRSS
which in aggregate represent 80 to 90% of all digital activity and
all have an occupied bandwidth of 300 Hz or less (in many cases
much less).
One could further address ARRL's request for bandwidths of up to
2.8 KHz by allowing "RTTY, digital" in those portions of the HF amateur
bands (excluding 160, 60 and 30 meters) where "phone, image" modes are
currently permitted. Bandwidth of 2.8 KHz would be consistent with the
modes currently permitted in those allocations and would facilitate
amateur experimentation with digital voice modes.

I recommend others file additional "Petitions
for Rule Making" that asks that the maximum bandwidth in the current MF and HF
"RTTY, Data" allocations be set at 500 Hz -
"consistent with historical use of traditional radioteleprinter bandwidths" and
other modern data modes such as PSK31, JT65A, JT9,
etc, and that wider bandwidth digital modes such as PACTOR 3, PACTOR 4,
M110A/B/C, ALE, etc. be grouped with phone and image
transmission due to their 2.8 KHz compatible bandwidth.

This is an excellent idea. I have actually been thinking about this very thing.
I just don't know how to go about it. Anyone in this
group have experience in doing this? It certainly need to be well thought out
and well written.
Or is this a good idea? What are the chances of there being enough comments
against the present proposal to make the FCC turn it
down? Is it better to fight on one front or two?
