Not with a single transmitter. You could build a comb generator and
modulate it for AM, but the quality would be poor For FM you either need
separate transmitters, or modulate the signal and mix it with a separate
oscillator for each channel

Nah, given a wideband signal source and amplifier, there's conceptually no
reason he couldn't broadcast on all stations simultaneously! I find it a
novel idea, actually.

The big question is why you would want to
do it.

I suspect he's thinking of something like those 'talking houses' where
you're supposed to tune your radio to a given station and get information on
why you want to drop a quarter million bucks on a thousand square feet of
your very own sometime in the next 20 minutes... except he doesn't want
people to have to tune at all!

Slightly less evil would be emergency broadcasting type uses...
