If Channel 2 or 11 were SFNs from Balt and from NYC, those Ch 2 and 11 frequencies would STILL BE UNUSABLE in Philadelphia. You just aren't getting it, Craig. The only way to avoid that would be to convince the owners of those Balt and NYC stations that they should deliberately disenfranchise communities between the two market centers. Only then could Ch 2 and 11 also be used by Phila stations. Which would be dumb. For one, because people in those large areas work or play in the Balt or Phila markets. Besides which, if every station willingly cut off its signal from large areas between major market centers, to create the buffer zones you seem to like, there would be large areas of the East Coast with no usable OTA signals. > Wrong.

The way you control interference is that you locate areas of co-channel interference or low signal levels where it doesn't matter. Just as they have done. What you continue to miss is the concept of providing ubiquitous coverage. I guess you're trying to make a case that DBS is mandatory. I'm saying it is not.
