[RTTY] RM-11708 has been amended.

[Kai]

Chen,
Remember this crucial point:
The only thing restricting BW today is the general unavailability of radios with 
SSB bandwidths greater than the average of 2.45 kHz BW.
PACTOR3 was designed to use 2.2 kHz EXACTLY because wider would not fit in 
today's radios. That will change as SDR becomes more and more available, so:
*We do need a BW limit*,
The question reduces to what that BW should be, noting that 2.2 kHz accommodates 
all current users, and excludes no one (FCC "in the public interest" ruling).

Pick a number between 2.2 and 2.8 kHz,
argue for the number by providing evidence that anything higher than your number 
causes grievous harm to current user.
That's where I got stuck!

73,
Kai, KE4PT
