[RTTY] ARRL attack on current RTTY users

Al,
Thanks for posting the W8JI link. The best technical/social explanation 
I've seen that clearly articulates why the ARRL proposal is bad for RTTY.
2.8 kHz signals do not belong in the digital sub-bands. They belong in 
the phone bands with digital phone and SSB.
The symbol rate argument is a smoke screen for the bandwidth issue.
73,

"CB") because it's from the ARRL and contains the letters "A", "R" and "L"; and the second shooter/9-11 inside job conspiracy fans that believe the HF bands would be overrun by millions of yacht owning hams checking their email.

But allowing 2.8 kHz bandwidth signals anywhere RTTY is allowed would be detrimental during contest weekends, when you can find RTTY operators well into the .100+ segments of the bands that are forbidden to SSB in the US but nowhere else in the world (a tangent I won't belabor here).  How many RTTY signals can coexist cheek to jowl in any 10 kHz segment of spectrum?  How many 2.8 kHz wide modes?
