The original discussion was about the operators of the mode starting up 
on top of another or very near another AM or SSB conversation.  They can 
operate any mode they choose provided they operate in a considerate 
manner.

If the mode is digital and the ID is digital, then why aren't they 
allowed in the digital portion of the band?  I wonder if this decision 
has anything to do with the wideband/narrowband argument.  Also the 
argument is that if you change analog to digital, what mode is it?  So 
if you transmit a digital stream, is it digital, therefore the operator 
should be in the digital portion of the band?  The mention of them 
communicating by SSB is a bit trite to me.  If they are using a digital 
mode why can't they communicate info other than pictures by digital 
modes?

I don't believe that is what happened so fine they can operate anywhere 
they choose in the phone portion, but they need to use that big knob on 
the front of their radio if someone is already on or very near 3.713 
They don't want anyone else in their passband if it messes up their bit 
stream just like we don't want a bit stream in our passband causing us 
to lose part of the transmission.

Live it up and enjoy your mode!
