April 2021 KACS(FM) Channel 213C2 Chehalis, Washington Allocation Study The attached spacing study shows the co-channel and adjacent channel spacing between stations and demonstrates that the proposed operation meets the IF channel spacing requirements as prescribed in §73.207 of the Commission's Rules. The attached allocation study map exhibits demonstrate requisite contour protection for the following domestic stations close enough to warrant detailed study, with the exception of overlap received from KPLI, as discussed in a separate exhibit: Cochannel: KGIO 213A Astoria, OR First-Adjacent: KEXP-FM 212C3 Seattle, WA KLWO 212A Longview, WA KBOO 214C1 Portland, OR Second-Adjacent: KVTI 215C1 Tacoma, WA KPLI 211A Olympia, WA KUPS 211A Tacoma, WA Third-Adjacent: KGRG 210A Auburn, WA KGHP 210A Gig Harbor, WA All contours depicted have been calculated using terrain HAAT data from the 3-second terrain database. CBCV-FM Channel 213C Victoria, BC The proposed operation is short-spaced to Canadian station CBCV-FM on Channel 213C at Victoria, British Columbia. Under the terms of the Working Arrangement for the Allotment and Assignment of FM Broadcasting Channels Under the Agreement Between the Government of Canada and the Government of the United States of America Relating to the FM Broadcasting Service , as amended in 1997 (" Working Arrangement "), the required co-channel Class C to Class C3 spacing is 259 kilometers, whereas the distance between the proposed KACS site and the CBCV-FM transmitter site is 216 kilometers. The attached cochannel allocation study map Hatfield & Dawson Consulting Engineers demonstrates that the proposed KACS 34 dBu F(50,10) contour will not overlap any Canadian land areas, nor does it cross the Canadian border.
