I have no reason to believe that is true -- indeed, at Dayton, I heard 
an ARRL director quoted as saying the League is "dug in" and have no 
intention of backing away. I am strongly against their petition, for the 
reasons Stuart has cited.

Here's the issue. Up to now, broadband digital modes are pretty much 
useless for data communications because of the 300 baud limitation, even 
though 2.8 kHz bandwidth is permitted on both CW and SSB segments of the 
bands. With the 300 Baud limit removed, there are many, including me, 
who believe that the CW bands will be filled with 2.8 kHz wide internet 
routers, many of them moving traffic to boats around the world.

Put simply, implementation of this petition could easily kill CW and 
narrow data modes -- heck, it might even kill those so-called traffic 
nets on 20M!
