Fast answer without listening to the sound yet..In theory you should have
the upper sum harmonic with the X input as output from the Mod Demod..
So if your sound is a low sine chances are that the difference harmonic is
too low to hear..
Leaving thereby only the sum harmonic and the leakage from the X input...
