[BC] Stereo Pilot question...

[Broadcast List USER]

Actually, we (stupidly) studied this quite extensively.  With today's  
available FM decoder chips, going below 3% causes NO DIFFERENCE in  
stereo decoder performance.

Some less than careful tests showed that even at 1% or even a bit  
less, it STILL makes no difference.

The stereo decoders just need SOME zero crossings of some 19 kHz  
signal to continue to properly decode the stereo subcarrier, and it  
doesn't change noise or blend one bit.

Sadly, cannot share the entire work product, but this is the core  
result.
