Good points, the following is a quote from Ed Williams of PBS. Source DigitalTelevision.COM

Quote:
Another DTV urban legend is that "on–channel repeaters or single–frequency networks cannot be used with 8–VSB." This is simply not true. Not only is it possible, but broadcasters likely will do both. Experiments have been conducted recently and plans are underway to construct both.


Here's another: "The FCC failed to allocate channels for translators for DTV." That's correct when put in context. The FCC did not allocate channels for NTSC translators either. Both are secondary service. However, DTV translators will fit into TV spectrum where NTSC will not because DTV translators can operate at lower power and DTV provides better protection ratios.

See the thread "Idea to increase HD Programming in small towns" at:

They believe that very low-power DTV translators can be squeezed into the vacant channels between higher-powered NTSC translators, as long as the NTSC translators keep down the out-of-channel noise. They would replicate the same coverage areas.

Since the FCC is hesitant to require the cable TV carry DTV signals, what is the status of DTV translator allocation. This may be a perfect way to bypass the cable company. Here in Sonoma, we are shielded by several mountains. I have to use antennas at various heights to guarantee coverage (due to knife edge diffraction). A low powered translator here would serve the whole community well, as well as several other signal challenged valleys here. In addition, the lower power requirements/adjacent channel performance of 8VSB would make translators even more feasible than with NTSC.


Another possibility is MMDS, Since the cable companies aren't willing to step up to the plate, the FCC should be lenient to companies willing to provide DTV service via this medium, with the higher SNR available, the CATV 40 Mb/6MHz option would probably work, that means 10 DTV channels could be squeezed into 30 MHz of bandwidth.
