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.
73, Rene' _____ From: [email protected] [mailto:[email protected]] On Behalf Of Rene Tetro Sent: Thursday, March 03, 2011 2:13 AM To: [email protected]; 'International Radio Club of America' Subject: [ABDX] 990 in the Northeast 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. 73, Rene' Rene' Tetro Director of Engineering WNTP-WFIL Philadelphia __._,_.___ Reply <mailto:[email protected]?subject=Re%3A%20990%20in%20the%20Northeast> to sender | Reply <mailto:[email protected]?subject=Re%3A%20990%20in%20the%20Northeast> to group | Reply <http://groups.yahoo.com/group/ABDX/post;_ylc=X3oDMTJyMXV2NjAzBF9TAzk3MzU5Nz E0BGdycElkAzE1NzA1ODIxBGdycHNwSWQDMTcwNTA2MzEwOARtc2dJZAM0OTYyOARzZWMDZnRyBH NsawNycGx5BHN0aW1lAzEyOTkxMzYzNzA-?act=reply&messageNum=49628> via web post | <http://groups.yahoo.com/group/ABDX/post;_ylc=X3oDMTJmaTJnM2t2BF9TAzk3MzU5Nz E0BGdycElkAzE1NzA1ODIxBGdycHNwSWQDMTcwNTA2MzEwOARzZWMDZnRyBHNsawNudHBjBHN0aW 1lAzEyOTkxMzYzNzA-> Start a New Topic Messages <http://groups.yahoo.com/group/ABDX/message/49609;_ylc=X3oDMTM3Y3NwbmNzBF9TA zk3MzU5NzE0BGdycElkAzE1NzA1ODIxBGdycHNwSWQDMTcwNTA2MzEwOARtc2dJZAM0OTYyOARzZ WMDZnRyBHNsawN2dHBjBHN0aW1lAzEyOTkxMzYzNzAEdHBjSWQDNDk2MDk-> in this topic (4) Recent Activity: * <http://groups.yahoo.com/group/ABDX/members;_ylc=X3oDMTJnMzYwZ2RwBF9TAzk3MzU 5NzE0BGdycElkAzE1NzA1ODIxBGdycHNwSWQDMTcwNTA2MzEwOARzZWMDdnRsBHNsawN2bWJycwR zdGltZQMxMjk5MTM2Mzcw?o=6> New Members 1 <http://groups.yahoo.com/group/ABDX;_ylc=X3oDMTJmcXRzMTNmBF9TAzk3MzU5NzE0BGd ycElkAzE1NzA1ODIxBGdycHNwSWQDMTcwNTA2MzEwOARzZWMDdnRsBHNsawN2Z2hwBHN0aW1lAzE yOTkxMzYzNzA-> Visit Your Group The ABDX website www.abdx.org! <http://groups.yahoo.com/;_ylc=X3oDMTJlNmpidHV1BF9TAzk3MzU5NzE0BGdycElkAzE1N zA1ODIxBGdycHNwSWQDMTcwNTA2MzEwOARzZWMDZnRyBHNsawNnZnAEc3RpbWUDMTI5OTEzNjM3M A--> Yahoo!
