Did some research on Alps UHF modulator, these are limited to channels
30 - 37. I am wanting more channel range, but these would be
good for experiments I suppose.

What I want is to ask if upconverting the HF television signal to the
center frequency of the UHF channel would have the same overall effect
as using a direct modulator.. The physics says probably yes, but are
there any showstoppers other than physics?
