                             ERRATUM

Released:  August 4, 1999



By the Chief, Office of Engineering and Technology:

     
1.  On December 18, 1998, the Commission released its Second Memorandum Opinion and
Order on Reconsideration of the Fifth and Sixth Report and Orders (Second MO&O) in MM
Docket No. 87-268, FCC 98-315, 14 FCC Rcd 1348 (1998).  That action revised and clarified
certain aspects of the Commission's policies relating to channel allotments for digital television
(DTV) service in response to requests from petitioners.  This Erratum restores text that was
inadvertently deleted from Section 73.622(e) in the Second MO&O.

     1.  Section 73.622 is amended by adding a note to paragraph (e)(2) and adding a new
paragraph (e)(3) to read as follows:

 73.622 Digital television table of allotments.

     *     *     *     *     *

  (e) DTV Service Areas.

  (2)  *     *     *

Note to paragraph (e)(2):  During the transition, in cases where the assigned power of a UHF
DTV station in the initial DTV Table is 1000 kW, the Grade B contour of the associated analog
television station, as authorized on April 3, 1997, shall be used instead of the noise-limited
contour of the DTV station in determining the DTV station's service area.  In such cases, the
DTV service area is the geographic area within the station's analog Grade B contour where its
DTV signal strength is predicted to exceed the noise-limited service level, i.e., 41 dB, as
determined using the Longley-Rice methodology.
  (3) For purposes of determining whether interference is caused to a DTV station's service area,
the maximum technical facilities, i.e., antenna height above average terrain (antenna HAAT) and
effective radiated power (ERP), specified for the station's allotment are to be used in determining
its service area.
