"BREAKING NEWS! THE REAL REASON WHY WGN HAS DROPPED HD-AM"

"HD-AM has been dropped because it's interfering with Arbitron PPM
technology! IOW: the self-interference inherent in HD is preventing
the PPM devices from reading WGN listening in the field. IOW: HD
Radio
is directly blocking reportage of AM listening to Arbitron! This
confirms the suspicions of most posters here about James Carollo's
explanation that processing changes being evaluated being a plausible
reason for shutting the HD exciter down... Put yourself in the
position of a big cash-cow major market AM General Manager. What's
gonna win? Hiss-O-Matic Interference Generator, producing a
questionable product consumed by an infintesimal segment of your
audience, or...Arbitron, which directly influences revenues for your
station?"

Let's see - the 10db power increase for FM-HD should have the same
affect! I love it! LOL!

The 'tard boy 'Eduardo' will be along shortly to give his in depth
explanation...
