  • interest. Finally, Mountain states that, in the event the grant is upheld, the license should contain more detailed conditions to ensure that Direct Connect does not cause interference to TV operations. discussion Television protection criteria. The engineering analysis supporting Direct Connect's waiver request concluded that the proposed operations would protect television operations because it met the technical parameters in Section 74.706(d)(2) of the Commission's Rules. Mountain contends that this is not the proper standard, because Section 74.706(d)(2) addresses protection of digital TV (DTV) stations by low-power TV stations, rather than by land mobile radio stations. Mountain argues that the stricter standard set forth in Section 90.545, which governs protection of DTV stations by 700 MHz public safety land mobile radio operations,

  • of the above-captioned application for a construction permit for a new low power television station to operate on channel 42 at Cherry Hill, New Jersey. For the reasons set forth herein, we deny NJTV's application for review. BACKGROUND On September 11, 1998, NJTV's application (File No. BPTTL-19810217TG) was dismissed because it failed to meet the interference protection criteria of Section 74.706 of the Commission's Rules. Specifically, the Division found that the proposed facilities were predicted to cause objectionable interference to full service television station WTXF-DT, channel 42, Philadelphia, Pennsylvania. NJTV appealed on the grounds that the dismissal of its application for interference after 17 years was a retroactive use of the interference protection criteria, in violation of the Administrative Procedure Act.

The rules also specify the use of different propagation curves, e.g., F(50,10) or F(50,50) depending on whether the undesired signal is a co- or adjacent channel.

In addition, minimum station separation distances apply to facilities using channels separated by 2, 3, and 4 channels and where the proposed facilities specify a channel that is 7 channels below that of the protected facilities.

The interference protection requirements in Sections 74.705 and Section 74.707 are similar in most respects.

Under this approach, to receive consideration as a minor change an application would need to include an engineering certification to show that a frequency study had been performed and that the requested change otherwise would be in full compliance with the rules. KMC notes that the rules for minor modifications in Section 73.3572(a)(2) should be amended to reference Section 74.706 as well as Section 74.705. 113. First Cullman requests that we require full service television stations whose DTV services will displace LPTV stations to keep the displaced LPTV stations accurately informed as to their application and construction plans relating to those services.

  • above the channel of the protected facilities. In addition, minimum station separation distances apply to facilities using channels separated by 2, 3, and 4 channels and where the proposed facilities specify a channel that is 7 channels below that of the protected facilities. This is the manner in which LPTV application proposals must protect authorized DTV service. See 47 C.F.R. 74.706 Prescribed in Sections 73.622 and 73.623 of the Commission's Rules and as described in OET Bulletin 69. The interference protection requirements in Sections 74.705 and Section 74.707 are similar in most respects. Because of the secondary status of LPTV stations, certain protection requirements to full-service stations in Section 74.705 do not apply to protection among LPTV and TV translator stations

We will permit the use of OET 69 type showings in support of requests to waive these requirements, and we will permit interference agreements among the affected parties. 5. LPTV, TV Translator, and Class A Modification Protection to Digital Class A We will adopt the requirements in Section 74.706 of the LPTV rules for the contour protection of digital Class A stations. Application proposals for analog LPTV, TV translator and those of Class A facilities modifications must protect the service contours of digital Class A stations to the extent provided by the D/U ratios in this rule. Application proposals for digital Class A stations must protect the service contours

  • Corporation ("NJTV") appeals from a Federal Communications Commission order dismissing its application to build a low- power television broadcast station. The FCC ordered dismissal, seventeen years after NJTV filed, because the station would unduly interfere with a full service television station on the same channel. New Jersey Television Corporation (NJTC), 18 FCC Rcd 24409, 24409 (2003) (citing 47 C.F.R. � 74.706). NJTV now requests us to order the FCC to keep the application on file and give it preferential consideration if the channel becomes available again. Alternatively, NJTV requests an order of "displacement relief"-permission that the Commission in some cases grants licensees and permittees to modify their broadcasting to reduce interference and thus preserve their broadcast entitlement-for which it would have
