listening, there is nothing being jammed, interrupted or covered up.

HD was "experimental" until last week. It only had an ad and promotion
campaign since June of last year. Nearly all of the significant stations
in
the top 100 markets are on HD or licensed to begin soon... about 2000 in
total, making up about 1700 FM and 300 AM:- Hide quoted text -

What you are really about, since IBLOCK will cut off fringe listening,
is attempting to justify this destuctive technology. The HD Radio
Cartel will find out, just how unimportant fringe listening is.

Nothing that fringe listeners can say or do will affect radio stations, as
radio stations know they are very few and, no matter how many they are, they
do not create any revenue which is what keeps us on the air.
