ALLEN & ASSOCIATES LTD. CONSULTING ENGINEERS Project #19841 TECHNICAL BRIEF NEW FM REBROADCASTING TRANSMITTING STATION CALGARY, ALBERTA 1.0 Purpose: It is the purpose of this Technical Brief to demonstrate that the proposed FM rebroadcasting station meets the requirements of Industry Canada, as set out in the following Broadcasting Procedures and the Canadian-U.S.A. FM Broadcast Agreement: - Broadcasting Procedures and Rules, Part 1, Issue 5: General Rules dated January 2009 - Broadcasting Procedures and Rules, Part 3, Issue 5, Amendment 1: Application Procedures and Rules for FM Broadcasting Undertakings dated June 2010 - Broadcasting Procedures and Rules, Part 4, Issue 2: Application Procedures and Rules for Television Broadcasting Undertakings dated January 2009 - Agreement Between the Government of Canada and the Government of the United States of America Relating to the FM Broadcasting Service and the Associated Working Arrangement (dated July 1997) amended February 2001 2.0 Discussion: Corus Entertainment Inc. proposes to install a new FM rebroadcasting station to rebroadcast the existing CHQR AM station in Calgary, Alberta. The proposed station will operate on Channel 295A (106.9 MHz) with an effective radiated power of 1.0 kW (H&V) and an EHAAT of 243.6 m. The proposed station will be a Class A station. The proposed Channel 295A station is second adjacent channel to CFGQ-FM on Channel 297C. CFGQ-FM is owned by the applicant. In order to minimize interference between the stations, the proposed new Channel 295A station will be co-sited with CFGQ-FM on the existing CBC tower in Calgary, Alberta. It is proposed to utilize the existing CBC tower in Calgary, Alberta. A new omnidirectional Dielectric DCR-H4 4-bay circularly polarized FM antenna will be side-mounted on the existing CBC tower.

CONSULTING ENGINEERS Project #19841 3.0 Channel Selection and Interference Analysis: 3.1 In the Industry Canada broadcasting database there are no Class A allotments for Calgary, Alberta. It is proposed to utilize Channel 295 as a Class A drop-in channel that is 2nd adjacent to CFGQ-FM, a Corus owned station in Calgary. 3.2 Channel Interference Analysis for the Proposed Calgary, Alberta Channel 295A Station 3.2.1 The distances to the nearest co-channel and adjacent channel allotments or assignments from the proposed site are as follows: Allotments or Channel Location Distance from Minimum Assignments Proposed Site Separation (km) Required (km) Co-Channel VF2320 295LP Fording River Mine S, BC 108.9 122 Field40 295A Field, BC 162.7 151 1st Adjacent Channel CFDV-FM 294C1 Red Deer, AB 139.3 168 CJRX-FM 294C Lethbridge/Taber, AB 184.4 186 2nd Adjacent Channel CIRI-FM 293LP Calgary, AB 14.8 40 CFGQ-FM 297C Calgary, AB 0 106 3rd Adjacent Channel - - 224 None within 150 km - - 298 None within 150 km 4th Adjacent Channel CFIT-FM 291C1 Airdrie, AB 29.7 - - - - 299 None within 130 km September 23, 2011 Page 2 D.E.M. ALLEN & ASSOCIATES LTD. CONSULTING ENGINEERS Project #19841 3.0 Channel Selection and Interference Analysis: 3.2 Channel Interference Analysis for the Proposed Calgary, Alberta Channel 295A Station (Cont'd.) 3.2.2 It is anticipated that no interference to allotted or assigned co-channel or adjacent channel stations will result from the proposed station. Distances between the proposed station and co-channel and adjacent channel allotments or assignments were checked, and in all instances meet the required distance separations set out in Broadcasting Procedures and Rules, Part 3 and Agreement Between the Government of Canada and the Government of the United States of America Relating to the FM Broadcasting Service and the Associated Working Arrangement (dated July 1997) amended February 2001 with the following exceptions: - Co-channel separation to Allotment, Field, AB on Channel 295A - Co-channel separation to VF2320, Fording River Mine S, BC on Channel 295LP - 1st adjacent channel separation to CFDV-FM, Red Deer, AB on Channel 294C1 - 1st adjacent channel separation to CJRX-FM, Lethbridge, AB on Channel 294C - 2nd adjacent channel separation to CIRI-FM, Calgary, AB on Channel 293LP - 2nd adjacent channel separation to CFGQ-FM, Calgary, AB on Channel 297C September 23, 2011 Page 3 D.E.M.

The Field Allotment 34 dBu interfering contour (based on maximum Class A parameters) does not overlap the 54 dBu contour of the proposed station (see Figure 6). September 23, 2011 Page 4 D.E.M.
