Perhaps not. After all, the 8-VSB folks could lower their transmitter 
power to compete.

I had a VERY interesting talk with Merrill Weiss yesterday, about the 
work he has been doing with 8-VSB SFNs.

Not sure how Bert is going to react to the realities of what Merrill 
told me.  Before I start to discuss the details with the list I want 
to look at some of the papers he presented here at NAB and see if I 
can get something to link to.

But the bottom line is that it looks quite possible to cover each 
market with a handful of synchronized transmitters (~5). The power 
levels for each would be a few KW as opposed to MW. Even better, if 
all channels were co-located at these sites, it might be possible to 
use EVERY channel, much like a cable system. He is building such a 
system for a client, and is working with the FCC on an NPRM to 
establish appropriate rules.

More as I learn more.

Craig
