It seems to me that CW will be more toward the bottom of the band and
Data/RTTY will be more toward the top of the band. Sometimes CW will be
over the entire band and it is possible for Data, particularly RTTY
during a contest, to be over much of the band too.
I certainly do not expect the FCC to reinstate an area for automatic
operation since the remaining 80 meter band is too small for this vis a
vis the amount of traffic on this band.
Remember that semi-automatic is permitted in any part of the Data/RTTY
areas as long as the bandwidth of the stations are not wider than 500
Hz. So Pactor 2 BBS systems can still operate. Same with PSKmail systems.
The only time fully automatic stations can operate is if they are within
a designated automatic area of the band. Also, the only time a wide band
mode (anything over 500 Hz), such as Pactor 3 can be used in even
semi-automatic mode is within a designated automatic area of the band.
The automatic area of the 80 meter band should be ended on Dec 15th.
Even an unattended PAX2 BBS will no longer be legal and in the past
could only operate from the automatic area of the band.
After all the concern about not being able to operate these high speed
serial modems on the U.S. HF bands, how many hams are using them for
sending of images/FAX in the phone section where it is legal to do so?
If not, why not?

Somehow I doubt the non-extra-class CW ops will go for a
15 kHz segment (3525-3540)
Since 25% of the non-phone band is extra-only, wouldn't it
make sense to designate some of the extra-only sub-band
as digital? Not all extra-class operators operate CW.

Proposed New 80 meter Bandplan for USA
3500-3540 = CW
3540-3560 = 500Hz BW All Modes.
3560-3580 = 500Hz BW All Modes. Including Auto.
3580-3600 = All Modes. Including Auto.
