Dave and group members,

If the proposed bandwidth proposals ever go through, the wider modes 
would be required to operate higher in the bands. For example, on 20 meters:

14.000 - 14.065  would be the < 200 Hz modes such as  CW and PSK31/63 
and others that would be made to accomodate this BW
14.065 - 14.100 would be the 500 Hz and under modes such as RTTY, 
MFSK16, Clover II, Pactor 1 and 2
14.100 - 14.350 would be the wide modes up to 3500 Hz such as Olivia, 
MT-63, PAX, Domino, and Pactor 3

Although the narrow modes could legally be used in the wide band areas, 
you could expect that they would tend to stay in areas that would give 
them the most protection. Wide modes, such as Pactor 3 could no longer 
be used below 14.100 in areas under FCC administration. Same for ALE or 
other wide modes. It also means that Olivia, MT-63 and similar wide band 
modes would only be allowed to operate above 14.100, and would compete 
for a much more limited space for wide modes than we have now.

It would be even more difficult than is currently possible, for any 
radio amateurs who want to establish any kind of "channel" dedicated to 
some purpose since they will be more crowded with new digital modes that 
will likely be very wide band to maximize robustness and throughput in a 
limited 3500 Hz channel in the area above 14.100. And further, ARRL has 
indicated a willingness to come up with a bandplan that would tend to 
segregate analog voice from digital modes. My hope is that there would 
at least be some "interface" point where you could operate either of the 
modes, similar to what is currently allowed on SSTV.

While the information at "bandplans.com" is very helpful to see where 
some suggested operating frequencies might be with competing interests, 
the information is NOT in any way a "bandplan." Since no one individual 
or group owns the frequency, and others may use a given frequency with 
an appropriately legal emission for their license class, some of the 
information is more wishful thinking on the part of those who would like 
to see channelization of the amateur bands.

73,
