Would Sox games be on 93.7 HD signal?

[Dan.Strassberg]

I think you meant "power is allocated to the entire digital multiplex,
not to individual subchannels." Is that what you meant? (In other
words, isn't the word "not" immediately preceding the word "allocated"
an error?) If the corrected version above is what you meant, I fail to
see how what you meant differs in any material way from what I said in
the post with which you took issue. Now, if you meant to say "power is
NOT allocated to the entire digital multiplex, BUT RATHER to
individual subchannels," we have a disagreement and I don't understand
how what you are saying is--or could be--true. The digital power does
not appear to be a function of how many digital subchannels there are
or how a station allocates the available bit rate among its
subchannels.
