HD/IBOC violates international treaties - Mexico objects (Ha Ha Eduardo) !
 

"Mexico Says Hang on a Minute!"

"Mexico wants U.S. radio regulators to re-think their decision to
allow AMs to go IBOC at night and FMs to operate on the extended
hybrid digital carriers. Our neighbors to the south say they are not
happy the FCC authorized its recent "final" IBOC rules governing
broadcast transmissions without first coordinating those through
international treaties."

"Digital radio in Canada"

"The only comprehensive technical comments came from the CBC. They
stated that AM-IBOC ...would create a serious degradation in sound
quality for existing AM stations. (*all* AM stations, not just the
ones adopting IBOC) They also state that due to interference
concerns, ...IBOC transmission at night is not practical. As for FM-
IBOC, implementation ...would require additional first and second
adjacent channel coordination. and ...would make it difficult to
coordinate the CBC's network operations."
