I wanted to make it a straight tuning sequence for the family, dumping
analog
forever. Using the present analog modulator has been problematic with
adjacent
band bleedover, even intermitent skip propagation from nearby cities and
perhaps
poor design of the modulator itself (I tried 3 different models). All have
performed
marginally under the circumstances. I think given the nature of digital,
interference
at least would be eliminated. We live in the Chicago area with 25 off air
channels
available, and channels 3-4 are as usual tough to negotiate via a cheap
modulator
feeding 150 feet cumulative RG-6 and active quad splitter.Several
permutations of booster
vs. splitter combinations have yeilded no significant improvement. I
contemplated a
deep notch filter, but never got into it.
That's why I thought a robust ATSC modulator could fix the issues.
