Will Mexico soon be going to IBOC AM "HD" Radio Too ?

They are testing it now. One HD station is XEN 690, with 100 kw.

Will the increase in the number of American Radio Stations
Broascasting IBOC AM "HD" Radio -Hash-Out- the South
of the Border Mexican AM/MW Radio Stations ?

It's more the other way around. Mexico was later into using the AM band than
the US, so many US directionals take a dump on Mexico, where there has long
been resentment for electromagnetic imperialism (I'm not kidding... just
paraphrasing what was told me many times)

ARE THE DAYS OF THE BORDER BLASTERS NUMBERED ?

XERF is now only 100 kw, the Tijuana staitons are 50 kw and 77 kw, and even
XEROK (XELO) is down to 50 kw. I think you could say there are no more of
these critters.

Imagine XETRA-AM on 690 kHz Transmitting 50 KW of "Pure"
Over Modulated IBOC AM "HD" Radio into Southern-California
http://en.wikipedia.org/wiki/XETRA-AM
-and- Everything 50 kHz on either side of XETRA
being nothing but a Digital Hash Zone.

That station has more to worry about than going HD. In 14 months as a
Spanish talker aimed at LA (where they have no useful signal at all) it has
had no ratings in LA, SD or Tijuana.

DE - The point that I am trying to make is generally most
Spanish Music Radio Stations AM & FM tend to Over
Modulate their Signal and create Noise on both Adjacent
Radio Channels up-and-down the Band. Now take IBOC
"HD" Radio with the Digital starting point for the American
Broadcasters being 1/100th ERP of the Analog ERP.
-What-If- the South of the Border Mexican IBOC "HD"
Radio Stations start with a Digital Signal ERP of 10%,
25%, 50% or even 100% of their Analog Signal ERP ?
The Mexican IBOC "HD" Radio Stations will simply
over power the Americans and the Digital Adjacent
Channel Hash from the Mexicans will will make many
American Radio Stations un-hear-able within their Local
Market. Therefore the only 'choice' that many American
IBOC "HD" Radio Stations will have is to Power-Up
their Digital Transmitters to be heard withing their own
Local Market. The result will be a more rapid transition
to Full Power IBOC "HD" Radio and All "HD" Broadcasting.

let the digital {iboc} "hd" radio wars begin ~ RHF
