Because of the 'limited' number of AM/MW and FM Radio Stations

is not a Technical Problem; as it is not a Technical Problem in the

abundance of both AM/MW and FM Radio Stations that IBOC is a
significant Technical Problem and then the main problem is AM/MW
Nightime Interference due to Medium Wave propagation.

- All of Latin America has higher power, closer packed AM and FM

d'Eduardo,

Most 'countries' around the World have Government Controlled
{Limited} Media : Which Translates to Fewer Radio Stations per
10-K Square Miles then the USA.

Yes these Government Controlled Radio Stations are Higher
Powered then in the USA.

Plus the AM/MW 9 kHz Band Plan does make things more
compact then the USA's 10 kHz Band Plan.

I 'predict' that China (PRC) will be going to IBOC Broadcasting
on both AM/MW and FM Radio. Much lower Cost for Media
Expansion to 'serve' the Masses -vice- building all new Radio
Station's Transmitters and Towers. Followed by India etc . . .

IMHO - The 'future' of USA Terrestrial Based "Free" Over-the-Air
Radio Broadcasting is in an Expanded FM Radio Band. This can
be done by 'converting' the old Analog TV Channel 5 & 6 Frequency
Range 76~88 Mhz to the IBOC Digital Broadcasting and transfering
the majority of 'local' AM/MW Radio Stations to the FM Band.

it's a 'vision' thing ~ RHF
