CB Radio Prank

This is something I did 20 years ago to my younger brother that was in tech school learning electronics.
He was interested in cb radio but was discouraged about the background noise and 'skip'.
So as a prank  I put this box together.
I was so successful at fooling him he took 'my invention' to tech school to show off, the instructor was not amused when they took the cover off to exam how i did it. He was kidded for months about his invention, and was so mad at me for months.
 The idea is 'that by flipping a switch', extensive noise filtering and reconstruction algorithms rebuild the  original signal giving you an almost silent radio when no one is talking.CB enthusiasts wow over it until they try to use the radio, and realize the signal cant get out.
