Just finished having a little chat with a general manager for several
radio stations here in West Virginia. A few of them are transmitting
HD. This poor fellow is still under the illusion that HD radio is set
to take off like a rocket. He sites Ford's decision to make HD radio
an option for '08 and thinks that other auto manufacturers are on the
verge of announcing their introduction of HD radio as an option. I
informed him that the local Best Buy has had the same two RCA HD-100
radios on the self for several months with no takers and that the
local Ford deal was unaware of the HD radio option. How detached can
these people be? It's no wonder listeners are dropping like flies.

The interesting thing about all this is that one of the HD FM stations
has a very annoying buzz on the analog transmission side that I
suspect is being cuased by poor implementation of the Hybrid Digital
equipment and it's been there for months. This poor fellow informed
me that it's a defective microphone in one of the studios. Funny
thing, it occurrs during music and remote network news. Who does he
think he's fooling. It's obvious to me that he nor anyone else is
listening close enought to discover the wonders of HD radio.

Any asymmetry in the transmission/reception path will cause the IBOC
buzz to be heard. A badly tuned transmitter, tower, receiver IF
bandpass; anywhere in there.
