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?

The Eternal Squire

Converting TV channels - even upwards to UHF - is commonplace in cable
and MATV systems. I would skip the chanel 3 conversion and go straight
modulator to UHF if I were you unless you have a need for the ch. 3 signal.

A modulator which tunes the entire band does add to the cost. You can
get commercial units that tune all channels if thats a necessity.

I was just thinking...remember the "Rabbit" system that was popular
about a decade ago? It was used for transmitting a signal from your VCR
or sat rcvr to other sets in the house. I can't recall if it used UHF
or some proprietary frequency. That might be worth looking into.
