Actually Broadband Ham Net has nothing to do with the symbol rate change 
that is proposed by FCC and was backed by ARRL.  ARRL was trying to do 
away with artificial baud rate limits which make packet less useful than 
more modern digital programs.

The League overlooked the potential problem of allowing SSB bandwidth 
digital formats below the traditional digital band parts at top end of 
CW low-in-the-band operations.  Rather, they were not seeking to assign 
a band plan; but RTTY and CW fans have quickly rallied to protest any 
blanket approval of wider modes on top of CW.  Technically, you can 
operate CW anywhere in the band. In reality, if digital modes come on 
and operate without listening to see if a frequency is clear of ANY mode 
already in progress, CW operation or RTTY, would be untenable.

The CW and RTTY low end of the bands crowd have the attention of the 
ARRL Board now, and the Board hopefully will come up with a co- 
existence plan
Such that CW / RTTY and other low power modes won't be displaced by 
modes having a SSB bandwidth.  And digital users will have to listen for 
other modes before transmitting.
