I took a look on the "Coast to Coast" web page to check out all the

other
stations that broadcast it. I made a list of every 50KW AM station in

the
US east of the Mississippi that they listed and I tried them all. Here

are
the results...


Do note that most AM stations that run more then 1KW at night use
directional antennas. Sometimes (example: WBT) the directional pattern
favors you; other times (example: KFAB) it doesn't. On 1110, if WBT and
KFAB were to both use non-directional antennas at night, the two
stations would severely interfere with each other - even within their
intended service areas. So WBT limits the amount of power radiated
towards Omaha, and KFAB limits the amount radiated towards Charlotte.

(in some cases, more than one other station must be "protected", leading
to some pretty complicated antenna patterns!)

Directional antennas can SEVERELY reduce the "effective radiated power"
in particular directions. I live about 25 miles from 50,000-watt
WLAC-1510, but I'm in one of their directional nulls. Their effective
power at my location at night is roughly 600 watts, and it's not unusual
for me to hear other stations besides WLAC on 1510. Many other stations
are far *more* directional than WLAC.

A few notes about the stations you tried:

WTIC 1080 in Hartford, CT : Audible and clear above the noise, but

fades

Directional, protects KRLD in Dallas.

WGY 810 in Albany, NY : Audible and clear above the noise but fades out


Non-directional

WPHT 1210 in Philadelphia, PA: Audible, but fading in and out

regularly.

Non-directional

WBT 1110 in Charlotte, NC: Audible and strong. Minimal fading. S7 to

S8

Directional, protects KFAB in Omaha.

WTAM 1100 in Cleveland, OH: Perfectly audible, strong and clear. No


Non-directional.

WRKO 680 Boston, MA: in USB with the NB on I can hear something

resembling

Directional. Certainly protects KNBR in San Francisco but I believe
numerous other stations (Montreal, Toronto, others) as well.

KSTP 1500 in St. Paul, MN: It's lost completely. All I can hear is a


Directional. Protects the other 1500 station you mentioned, which is
WTOP in Washington.

WHAS 840 Louisville, KY: News Radio. Talking about "Arnold's"

political

Non-directional. (no idea who the other station is!)

WLAC 1510 in Nashville TN: Can't hear it. It's completely stepped on

by

Directional, protects "The Zone" (WWZN) Boston and KGA in Spokane, Wash.
(I thought "Coast-to-Coast" was on WWTN-FM here but could easily be
mistaken)

WFLF 540 in Orlando FL: I'm not sure if I'm hearing it or not. I'm

hearing

Directional. The dominant stations are in Saskatchewan and Mexico but I
*believe* WFLF protects the entire Canadian and Mexican borders. I
won't even speculate on the other stations you're hearing!
