CHHA-1610 Toronto ON has applied to the CRTC to use a directional array and to use 6.25 kW both day and night instead of the currently authorized 10 kW - day, 1 kW - night.
The link to the actual application is dead so I do not know the nature of the proposed pattern, but I presume that they will protect Montreal. <http://www.crtc.gc.ca/eng/archive/2011/2011-327.htm> 1. Toronto, Ontario Application 2011-0056-0 Application by San Lorenzo Latin American Community Centre relating to the broadcasting licence for the community AM radio programming undertaking CHHA Toronto. The licensee proposes to amend the authorized contours by changing the antenna radiation pattern from non-directional to directional and by changing its transmitter power from 10,000 watts day time and 1,000 watts night time to 6,250 watts day and night time. All other technical parameters would remain unchanged. The licensee states that such a change in transmitter power would allow the station to regain lost listenership resulting from the night-time power reduction. The change in antenna radiation pattern was required to protect other AM stations from skywave interference. The proposed amendment would decrease potential listenership in the 15 mV/m contour during day time hours from 1,315,982 to 1,067,284 while increasing it during night time hours from 194,073 to 1,067,284. In the 5 mV/m contour, the proposed amendment would decrease the potential listenership during day time hours from 2,828,585 to 2,409,869 while increasing it during night time hours from 500,010 to 2,409,869. 73, Deane McIntyre VE6BPO _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
