Montreal is usually better at Burnt River than Winnipeg. Roochester and
Knoxville are by all accounts rarely heard at night. Philly is rare. Corner
Brook not in many years. Same with Providence.

Thanks to all who wrote back about 990 CKGM. You're input was invaluable.
I am hoping that we have the situation resolved now following a couple of
conversations with the station.

Hi guys,
I'm wondering if I could impose on some of you guys in the northeast? I am
having interference problems on 990 WNTP here in Philadelphia, largely
from
CKGM in Montreal. Their signal is so strong here at night that it
penetrates deeply within my licensed interference-free contour. It seems
unlikely that the signal I am seeing can be produced by their licensed
night
pattern, which is (at least on paper) very restrictive into the US. On
paper they should boom their 50kw almost entirely to the north while
supposedly having deep nulls at night toward Philly, Providence,
Rochester,
and Knoxville (as well as toward Winnipeg, MB and Corner Brook, NF).
You can see their licensed night pattern on the FCC Database:
http://www.fcc.gov/ftp/Bureaus/MB/Databases/AM_DA_patterns/403523-27563.pdf
You can compare that with their much less restrictive licensed day
pattern:
http://www.fcc.gov/ftp/Bureaus/MB/Databases/AM_DA_patterns/403523-27562.pdf
Now, here is what I would like to know: what signals seem to be
predominant
in your area on 990 at night? Does CKGM come in more strongly that what
you
would think their pattern should produce?
For those of you in areas with stations on 990, does CKGM present a
problem
to your local station at night?
Finally, if you are in an area south of Montreal, is it possible for you
to
listen and detect if you can hear them change pattern from day to night?
The
change toward the south should be significant. According to the
information
provided by the FCC, they should be changing pattern at about 6:00PM EST
in
March.
Any information you can give me concerning any of the above questions
would
be greatly appreciated. Thanks so much.
