It is multiplied if you use a transverter to go up to other bands.

Which is what I intended to do in the 1st place.

But. lets go with your "drift of a few at 144mc is added to the LO freq not 
multiplied in any way" and the addition of  "Depending upon the direction of 
the drifts it could be subtractive and improve the stability too".  From 
which I guess that you like to have to follow signals from stations up and 
down the bands in order to keep track of what they are trying to take you?

Great, I'll resurect my old crystal transmitters, where temperature decided 
where they drifted off to.  I'm sure that they will be very popular on the 
modern HF bands these days without proper feedback loops that would keep 
them within suitable frequency limits...

If not, why would you think that this was acceptable on VHF or UHF bands?
