FM can't have single sidebands due to it's very nature of the carrier frequency shifting (deviating). |

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... > SSB is only 1/3 of an AM signal.

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"... |
