I don't think this is the case (I seem to recall this being discussed before 
on this list) - Bob Orban or someone else good with the Math may care to 
comment, but correct me of I'm wrong, the major downside to broadcating in 
Stereo is the increased signal to noise ratio that comes with demodulating 
the L-r info - since the noise level increases with frequency in FM the 
penalty is quite high.
