Daytime, KNX covers from northern San Diego County to mid-Riverside County
to Southern Ventura County.


At night, due to, first, skywave / groundwave cancellation, the groundwave
coverage is much less than that... and the skywave coverage is pretty much
ripped most of the time due to the Mexican stations that are now operating
on 1070, especially the one in Cd. Obregón Sonora.


Advertisers do not buy outside the local metro, so the coverage, what
there
is, outside LA and Orange County, counts for nothing to the business side
of
KNX.


You need a better radio.


Sorry, but that is the service area of the station. At night, the
skywave-groundwave cancellation zone hits around Redlands, Hemet, Fallbrook,
etc. and makes fringe reception very difficult. And beyond that the Mexican
co-channels rip it up.- Hide quoted text -

IBOC AM "HD" Radio and "Mexican Co-Channels" - What If . . .

DE - "Mexican Co-Channels" That brings up a point :

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

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 ?

Will Spanish Language IBOC AM "HD" Radio Stations have
a 'Local-Market-Monopoly' over their South of the Border
Mexican AM/MW Radio Stations due to Digital Hash ?

ARE THE DAYS OF THE BORDER BLASTERS NUMBERED ?

=BUT= "IF" Many of the Larger and More Powerful South of
the Border Mexican AM/MW Radio Stations adopt IBOC
"HD" Radio Technology and ran thier Digital Transmitters
at a Full Power of 10-25-50 KW -won't- They Blow most of
the North of the Border American IBOC "HD" Radio Stations
out of their Local Markets with Super Signal and Mega
Digital Hash ?

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.
