It's not WEEI vs. WCRB - it's WEEI *and* WCRB

[John Francini]

Hmmm.  I would have thought that it would be based on something like  
picking up the IF frequency of the radio or something unobtrusive  
like that.  So instead they encode something into the AUDIO?????   
Just what we need -- more hash on analog radio --especially AM -- to  
go along with the IBOC hash...
