I'd like to see a 25-30 MHz amp work at 120 MHz. Ain't gonna' happen...

SSB is only 1/3 of an AM signal. FM can't have single sidebands due
to it's very nature of the carrier frequency shifting (deviating).

It *could*, but it would probably be a rather expensive unit... Basically it
would be two units built into one I suspect... Never say never with
electronics -- someone will come up with a way to prove you wrong...

Although I had never heard of anyone implementing SSB on FM, I was leaving
myself an out, just in case... As I said above, "never say never"...
