HAMILTON – CHCH has asked the CRTC for permission to use a new replacement UHF digital television transmitter, specifically the one formerly used by Toronto 1/Sun News Toronto. The Channel Zero-owned over-the-air TV broadcaster said in its application to the Commission the new replacement digital transmitter operating on CH15 will boost its coverage and help it regain viewers who previously tuned to its CH18 transitional DTV channel which was shut down in August as part of the digital transition. Comments on the application are due by January 11, 2012. www.crtc.gc.ca www.chch.com
