place the loudspeaker on the reverser serface of a mirror. Shake a little
Carborundum Powder over the surface while illuminating with torch light.
The feed from an photocell at 45 degrees to the light beam will deliver a
signal which when fed through sufficient audio amplification will
replicate a fully detected LSB signal.

However, in order to get "sufficient audio amplification" the signal needs
to pass thru Dilithium Crystals.


They cannae take it !!!!!!!!!!!
