Sec.  74.1205   Protection of channel 6 TV broadcast stations.

   The provisions of this section apply to all applications for construction
   permits for new or modified facilities for a noncommercial educational FM
   translator station on Channels 201–220, unless the application is
   accompanied by a written agreement between the NCE-FM translator applicant
   and each affected TV Channel 6 broadcast station licensee or permittee
   concurring with the proposed NCE-FM translator facility.

   (a) An application for a construction permit for new or modified facilities
   for a noncommercial educational FM translator station operating on Channels
   201–220 must include a showing that demonstrates compliance with paragraph
   (b), (c) or (d) of this section if it is within the following distances of a
   TV broadcast station which is authorized to operate on Channel 6.

                        FM Channel                          (kilometers)

   (b) Collocated stations. An application for a noncommercial educational FM
   translator station operating on Channels 201–220 and located at 0.4
   kilometer (approximately 0.25 mile) or less from a TV Channel 6 station will
   be accepted if it includes a certification that the applicant has
   coordinated its antenna with the affected TV station.

   (c) Contour overlap. Except as provided in paragraph (b) of this section, an
   application for a noncommercial educational FM translator station operating
   on Channels 201–220 will not be accepted if the proposed operation would
   involve overlap of its interference field strength contour with any TV
   Channel 6 station's Grade B contour, as set forth below.

   (1) The distances to the TV Channel 6 station Grade B (47 dBu) field
   strength contour will be predicted according to the procedures specified in
    Sec. 73.684 of this chapter, using the F(50,50) curves in  Sec. 73.699, Figure 9 of
   this chapter.

   (2) The distances to the applicable noncommercial educational FM translator
   interference contour will be predicted according to the procedures specified
   in  Sec. 74.1204(b) of this part.

   (3) The applicable noncommercial educational FM translator interference
   contours are as follows:

                        FM channel                            F(50,10)
                                                            curves (dBu)

   (d) FM translator stations authorized prior to June 1, 1991 with facilities
   that do not comply with the predicted interference protection provisions of
   this section, may continue to operate, provided that operation is in
   conformance with  Sec. 74.1203 regarding actual interference. Applications for
   major changes in FM translator stations must specify facilities that comply
   with the provisions of this section.
