April 2021 KACS(FM) Channel 213C2 Chehalis, 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 , 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. Therefore, the proposed operation is believed to be in full compliance with international allotment requirements.

TV Channel 6 Section 73.525 of the Commission’s Rules specifies a threshold distance of 193 kilometers for FM stations operating on Channel 213. There is no domestic TV Channel 6 station located within this threshold distance.

KACS 213C2 Canada Study Map 0 153045 Kilometers Hatfield & Dawson 4/2021 April 2021 KACS(FM) Channel 213C2 Chehalis, Washington Waiver Requested for Received Second Adjacent Channel Overlap

Chehalis Valley Educational Foundation (“CVEF”) proposes to increase the power and service area of its station KACS (Facility ID #10685), which is presently licensed on Channel 213A under BMLED-20150811AGH. The proposed upgraded facility has been designed so as to not cause any prohibited contour overlap to any existing station, authorization, or pending application, as per §73.509 of the Commission’s Rules. However, the proposed increased 60 dBu service area would receive overlap from one licensed second-adjacent-channel full-power station, specifically KPLI on Channel 211A at Olympia.

This proposal will not cause overlap to KPLI as the proposed 100 dBu F(50,10) interfering contour of KACS will not overlap that station’s 60 dBu F(50,50) protected contour. However, the proposed KACS 60 dBu F(50,50) contour will receive overlap from the 100 dBu F(50,10) contour of KPLI.

The 60 dBu contour from the proposed KACS facility encompasses an area of 2,929 sq km and a population of 227,247 persons per the 2010 Census (using the block centroid method).

Area and Population in Percentage of Proposed KACS 60 dBu Area Received Overlap Area from KPLI and Population

1 sq km 0.03% area 238 persons 0.1% population

No overlap, and thus no interference, will occur within the boundaries of the KACS community of license.

In Educational Information Corporation , Memorandum Opinion and Order, 6 FCC Rcd 2207 (1991), the Commission noted that it would be inclined to grant waivers of second- or third-adjacent channel overlap in circumstances where the benefit of increased non-commercial service heavily outweighs the potential for interference in very small areas. “...the Commission has given the staff delegated authority to act on waivers of received overlap of up to 10 percent where sufficient justification is provided.” Educational Information Corporation at 7. “The Commission has long

Hatfield & Dawson Consulting Engineers recognized the unique characteristics of the noncommercial service and the need for flexibility to respond to the growing demand for such service. We are also more sensitive today to the increasing limitations within the reserved band which reflect the increased demand for service over the last 30 years. For these reasons, we are now inclined to grant waivers of second or third adjacent channel overlap in circumstances such as WCPE's, where the benefit of increased noncommercial educational service so heavily outweighs the potential for interference in very small areas.” Educational Information Corporation at 10.

CVEF hereby submits that the circumstances of the instant case are functionally equivalent to those in Educational Information Corporation , and respectfully requests a waiver of §73.509 of the Commission’s Rules to permit the grant of the proposed KACS facility. CVEF acknowledges that future modifications proposed by the licensee of KPLI will not be construed as a per se modification of the KACS license.

The licensed KACS 60 dBu contour encompasses an area of 1,455 sq km and a population of 74,200 persons. The grant of this waiver request will allow KACS to increase its 60 dBu service area by 101% and its 60 dBu service population by 206%. CVEF believes that this represents a significant increase in non-commercial service to the area, justifying grant of the requested waiver.

Hatfield & Dawson Consulting Engineers April 2021 KACS(FM) Channel 213C2 Chehalis, Washington RF Exposure Study

Facilities Proposed The proposed operation will be on Channel 213C2 (90.5 MHz) with a maximum lobe of 40 kilowatts. Operation is proposed with a 4-element circularly-polarized, half- wavelength-spaced directional antenna. The antenna will be side-mounted on the existing KACS tower located atop Cook Hill.

RF Exposure Calculations The power density calculations shown below were made using the techniques outlined in OET Bulletin No. 65. "Ground level" calculations in this report have been made at a reference height of 2 meters above ground to provide a worst-case estimate of exposure for persons standing on the ground in the vicinity of the tower. The equation shown below was used to calculate the ground level power density figures from each antenna.

2 3340981.()× AdjERP Watts S(/)µ W cm = D2 Where: AdjERP(Watts) is the maximum lobe effective radiated power times the element pattern factor times the array pattern factor.

D is the distance in meters from the center of radiation to the calculation point.

Ground level power densities have been calculated for locations extending from the base of the tower to a distance of 500 meters. Values past this point are increasingly negligible.

Calculations of the power density produced by the proposed antenna system assume a Type 2 element pattern, which is the element pattern for the “double V” antenna proposed for use. The highest calculated ground level power density occurs at a distance of 194 meters from the base of the antenna support structure. At this point the power density is calculated to be 26.9 µW/cm², which is 2.7% of 1000 µW/cm 2 (the FCC standard for controlled environments) and 13.5% of 200 µW/cm 2 (the FCC standard for uncontrolled environments).

Hatfield & Dawson Consulting Engineers Calculations of the power density produced by KACS and the other stations at this transmitter site are summarized in the following table:

Avg or Peak ERP Relative Height Calculated Max Gen Pub Call Antenna Model Field AGL Exposure FCC Limit % of Limit

KACS 40 kW H FMModel 54 m 26.9 µW/cm² 200 µW/cm² 13.5% 213C2 40 kW V (Type 2) 4-bay half-wave double V

K259BG 0.25 kW V FMModel 46 m 4.1 µW/cm² 200 µW/cm² 2.1% Dipole (Type 1)

K292HN 0.25 kW V FMModel 27 m 12.7 µW/cm² 200 µW/cm² 6.4% Scala FMV dipole (Type 1)

These calculations show that the maximum calculated power density produced at two meters above ground level by the proposed operation of KACS and the present operation of the other stations at this site (were their maxima to coincide, which they do not) is 44 µW/cm 2, which is 22% of 200 µW/cm 2 (the FCC standard for uncontrolled environments).

The permittee/licensee in coordination with other users of the site must reduce power or cease operation as necessary to protect persons having access to the site, tower or antenna from radiofrequency radiation in excess of FCC guidelines.
