Discussion

This firm has been retained to prepare the required engineering report in support of aConstruction Permit Application for an FM Translator W286DC. This translator is currentlyauthorized to operate with an AMSL of 439.5 meters and an ERP of 0.100 kW (H&V) on CH286D.This Translator proposal requests a change in frequency to CH272. The Translator will continueto rebroadcast Primary Station WKAR(AM) – East Lansing, MI; Facility ID No. 41684.

The Translator as proposed will continue to be mounted on a tower bearing AntennaStructure Registration Number 1265362. A copy of the ASR is included in Exhibit 13.1.

The proposed fill-in Translator present and proposed service contours vs the WKAR(AM)Contours are shown in Exhibit 13.2.

It has been determined the Translator may be used in the area without interference to anyexisting FM broadcast station or facility. The proposed allocation is included in Exhibit 13.3(a)and the proposed allocation is included in Exhibit 13.3(b). Per §74.1233(a)((1)((i)(A)(2) upon ashowing of interference to or from any other broadcast station, remedial changes to any sameband frequency are permissible. The proposed move in frequency is intended to eliminateoverlap of co-channel station WMGC-FM interfering contour with the service contour of W286DC.W286DC previously reduced operating power to resolve interference complaints from WMGC-FM.The amount of overlap will be significantly reduced with a move of W286DC to CH272.

The applicant would like to note the existence of a §74.1204(d) Second/Third AdjacentChannel Given Interference Waiver Request toward WHZZ(FM) – Lansing, MI (CH269A) as notedin Exhibit 13.4. Protection has been based on the worst case calculated 115 dBµ F(50:10)Interference Contour, corresponding to the worst case 75 dBµ F(50:50) Protected Contour.Protection has been demonstrated through a downward vertical radiation study. Full protectionwill be afforded the facility as the interference will not reach a seven-meter artificial planerepresenting a standard two story home when taking into account the downward radiationcharacteristics of the antenna as supplied by the antenna manufacturer. The antennamanufacturer’s specifications are included in Exhibit 13.5.

The applicant certifies the proposed translator 34 dBu F(50:10) Interference contour doesnot enter Canadian territory. Documentation of the proposed 34 dBu F(50:10) Interferencecontour will be supplied upon request.

This translator is not within the affected distance of any TV Channel 6 stations.

The applicant would like to note use of the NED 03 second terrain database for terrainbased showings contained here-in.

Discussion (continued)

RADIATION PROTECTION: The Commission requires an engineering study regardingcompliance with the guidelines for human protection from radiofrequency radiation. This reportsection is in response to that provision of the Rules. The current Federal CommunicationsCommission guidelines for RF radiation protection are set forth in OET Bulletin No. 65 (Edition97-01), and the accompanying Supplement A, (Edition 97-01).

The FM Broadcast facility proposed in this application will not produce human exposure toradiofrequency radiation in excess of the applicable safety standards specified in §1.1307(b)(3) ofthe Commission's rules concerning RF contributors of less than 5%. Exhibit 17.1 provides thedetails of the study that was made to demonstrate compliance. The facility is properly markedwith signs, and entry is restricted by means of fencing with locked doors and/or gates. Any othermeans as may be required to protect employees and the general public will be employed.

In the event work would be required in proximity to the antenna such that theperson or persons working in the area would be potentially exposed to fields in excess ofthe guidelines set forth in OET Bulletin No. 65 (Edition 97-01), the transmitter power will bereduced or the station will cease operation during the critical period.

Exhibit 17.1Compliance with Radiofrequency Radiation Guidelines

The RF Compliance Study has been evaluated for human exposure to non-ionizing radiofrequency radiation at thetransmitter site. The site is intended to house multiple transmitters. The potential for human exposure to non-ionizingradiofrequency radiation at the proposed transmitter site has therefore been evaluated with regards to the §1.1307(b)(3), fivepercent (5%) contribution rule, for multiple transmitter sites.

The minor change to construction permit application for W286DC – East Lansing, MI, TN analog FM Translator (FacilityID: 156707 will operate on CH272D (102.3 MHz) with 0.1kW ERP circular polarization (H&V). The proposed operation willbroadcast from an antenna COR mounted 181 meters above ground level (AGL). The facility will operate with a two bayantenna employing an assumed worst case EPA Type 1 elements as defined by FM Model - Appendix B issued March 31,20161. This facility will not operate with HD/IBOC facilities at this time.

To evaluate the total exposure to non-ionizing radio-frequency radiation with regards to the five percent contributionexclusion rule, it is necessary to establish 5.0% of the maximum permissible limit. 5.0% of the 200 µW/cm² results in10 µW/cm². Therefore if the resulting contribution is less than or equal to 10 µW/cm² or 5.0%, the exposure is concluded to bewithin the guidelines of OET Bulletin No. 65 (Edition 97-01) and §1.1307(b)(3). Protection of the more restrictive uncontrolledlimit implies protection of the controlled limit.

Inspection of the graph below indicates the maximum contribution for the uncontrolled environment is less than the10 µW/cm² (5.0%) limit as set forth by §1.1307(b)(3), therefore the facility is in compliance with FCC guidelines. §1.1307(b)(3)states that facilities contributing less than five percent of the exposure limit at locations with multiple transmitters arecategorically excluded from responsibility for taking any corrective action in the areas where its contribution is less than fivepercent. Since this instant application meets the five percent exclusion test at all ground level areas, the impact of the proposedfacility may be considered independently from other facilities operating at or nearby this site. It is believed the impact of theproposed operation should not be considered to be a factor at ground level as defined under §1.1307(b)(3).

In addition to the protection afforded by the proposed antenna height above ground, the facility is or will be properlymarked with signs, and entry to the facility will be restricted by means of fencing with locked doors and/or gates if required. Anyother means that may be required to protect employees and the general public will also be employed. In the event work isrequired in proximity to the antenna(s) such that the person or persons working in the area will be potentially exposed to fields inexcess of the current guidelines, an agreement signed by all broadcast parties at the site will be in effect for the offendingtransmitter(s) to reduce power, or cease operation during the critical period.

1 The current FM Model web-based softwareapplication employs the standards as detailedin OET Bulletin No. 65 (Edition 97-01). FMradiofrequency radiation levels have beenpredicted using both the array pattern, thecalculations of which are based on the numberof bays in the antenna and wavelength spacingbetween the bays, and the element pattern.The element pattern has been determined byusing measured element data prepared by theEPA and published in “An EngineeringAssessment of the Potential Impact of FederalRadiation Protection Guidance on the AM, FMand TV Services,” by Paul C. Gailey andRichard Tell - April 1985, U.S. EnvironmentalProtection Agency. The results of theevaluation for the FM station have been shownat the end of this RF compliance discussion.To ensure complete protection, the maximumFM contribution has been assumed withoutregard to any restricted access fencingdistance.
