[Vision2020] Digital Television:HDTV:1080 Interlaced/720 Progressive

[Ted Moffett]

Sam and others:

I can get PBS 7 from EWU near Spokane (or where they transmit from) and 
Channel 6 NBC from Spokane, quite well in a location not very "high" near 
Cornwall, with just a very carefully placed set of the nostalgic "rabbit 
ears."  What I wonder is if the digital signals from Spokane are as robust 
in reaching distant places as the analog signals they also are broadcasting 
at this time?  I have heard that the new digital video signals and the 
method of transmitting them are not as robust as the old analog signals 
which have led some advocates to consider revamping the whole digital 
broadcast system.  I imagine the local HDTV from 12 PBS is easy to get.  I 
did not know 12 is using the digital bandwidth right now to send several 
channels.  This is inspiration to go digital.
