[BC] Noise Floor...

Until the FCC decides to enforce the part 15 rules, all of them, then 
the noise floor will continue to climb and the best of receivers will 
only hear noise where there is noise.

I remember years ago, using only a simple table model receiver, I was 
able to hear AM stations across the country at night.  Now all I can 
hear are noise from computers, light dimmers, soda-vapor street 
lights as well as a myriad of other devices.  I have yet to be 
convinced that digital communications is going to be immune from the 
same or similar levels of "noise".
