''...a draft Report and Order to allow all U.S. AM
stations to use HD Radio at night is reportedly sitting on the
FCC Chairman's desk. Insiders say the document will allow all
stations (with equipment in place) to light up simultaneously.
Hopefully an interference resolution mechanism is included in the
paperwork. Broadcast engineers surveyed on the floor of the NAB
were not optimistic about the long-term prospects of AM HD at
night, but iBiquity investors will undoubtedly make a concerted
effort to make it work.''
