WBCN broadcast in full-time "quadrophonic" for a period in the early 70's. 
I think it was around 1973, or somewhere in there. 

Of course, not many of the records were actually quadraphonic, so they were 
actually broadcasting in "fake" quadraphonic by fooling with the phasing 
and EQ of the different channels, sort of like the fake "stereo" records 
remastered from mono tracks in the early 60's.

I never actually heard this effect on a quadrophonic receiver, but I recall
that the processing caused some cancellation when mixed to mono, resulting 
in a tinny sound from mono receivers.
