FCC Form 2100 DTV Allocation Considerations June, 2017 Post-Transition DTV Considerations A study was performed using the FCC’s software program, tv_study, v.2.2.2, to determine if the facility proposed herein is predicted to cause new prohibited interference to post reassignment DTV station, construction permits, DTV allotments, or Class A DTV stations. As demonstrated in the attached study results, the instant proposal is predicted to cause no new interference exceeding 0.5% to the populations served by any post reassignment DTV station, construction permit, allotment, or Class A DTV stations. In addition, the attached study also demonstrates that the predicted service area resulting from the technical facility proposed herein is within the baseline service area plus 1% and the proposed service area population is more than 95.0% of the baseline service area population. Accordingly, the instant proposal satisfies all applicable DTV coverage and DTV interference criteria. International DTV Considerations As shown in the attached study, the transmitter site specified herein is within 320 kilometers of the common border between the United States of America and Canada. As demonstrated in the attached study, the assigned, post transition, technical facility proposed herein satisfies DTV interference criteria with respect to all relevant Canadian allotments, applications and assignments. tvstudy v2.2.2 Database: localhost, Study: WJAC_35_382H_1MW_DIE, Model: Longley-Rice Start: 2017.06.30 10:14:27 Study created: 2017.06.30 10:14:17 Study build station
