It's an attractive idea but is it possible on System A to insert the AM sound in the form of a sub-carrier? That is simply modulate a 3.5Mhz carrier and supply the vision modulator with both the baseband video and the modulated 3.5Mhz.
It's one of those things I've often considered but never put in practise.
The modulated sound carrier will be above the vision carrier which is incorrect for Sytem A.
