think to. Of course, you are joking when you try to tell people about the
interference that you don't get from the local IBOC stations.

I've seen the shape of one on a screen capture. Yes, I know, not the
same thing, but still.

On AM, if you try to tune in a faint out of market station in the
daytime -- say AM 74 out of Huntington, NY -- which is between AM 710
and AM 77 in New York (both IBOC stations), you can't. If you're not
getting hash from 710, you're getting it from 77, either of which
wipes out the already pitiful reception of this peanutwhistle on AM
74.

If you try to tune in AM 1240 out of Morristown, NJ, you'll be hit
with interference from AM 1280 (another local station running IBOC).

Here we have:

780 KKOH
790 KABC
810 KGO

all obliterating each other and all owned by the same company. AM is
about to die.

I only get KGO at night as expected, but am much closer to KABC 790 and
especially XESPN 800, neither of which 'obliterate' KGO, even when D
layer propagation is poor.

This guy sure messes with KGO:

David,

Usually get all these very well at Night
with out any interference :
KSFO 560 kHz to the West
KMJ 580 kHz to the South
KEAR 610 kHz to the West
KFI 640 kHz to the South
KNBR 680 kHz to the West
KDWN 720 kHz to the South
KCBS 740 kHz to the West
KFMB 760 kHz to the South
KKOH 780 kHz to the North
KGO 810 kHz to the West
KTRB 860 kHz to the West
But they have to make the Trip up over
the Hill and Down into the Valley.

That Ciudad Juarez station you referred to isn't heard here because of
its co-channel in Tijuana. I'm line of sight (13 miles) from this one:

and can still manage to pull KGO from underneath, unlike back when it
was XEMM an over modulated splattering Mariachi Machine that no amount
of filtration could overcome.

When I lived in Phoenix I could hear X-Rock 80 at high noon in my '56
Cadillac. But that was a REAL radio.
