ORDER GRANTING EXTENSION OF TIME
FOR FILING COMMENTS AND REPLY COMMENTS
Adopted:  August 6, 2007 Released:  August 6, 2007
Revised date for filing Comments: August 15, 2007
Revised date for filing Reply Comments: August 30, 2007
By the Chief, Media Bureau:
1. On April 25, 2007, the Commission adopted the Notice of Proposed Rulemaking for the
Third Periodic Review of the Commission’s Rules and Policies Affecting the Conversion to Digital 
Television (“Third DTV Periodic NPRM”) to assess the progress of the transition to digital television 
(“DTV”) and make any necessary adjustments to the Commission’s rules and policies to facilitate the 
introduction of DTV service and the recovery of spectrum at the end of the transition.  The Third DTV 
Periodic NPRM requested comment on the procedures and rule changes necessary so that broadcasters 
can complete the transition to their final, post transition (digital) facilities by the statutory deadline, 
February 17, 2009.  Comments on the Notice were initially due on August 8, 2007, and reply comments 
were initially due on August 23, 2007. 
2. On August 3, 2007, the Association of Federal Communications Consulting Engineers 
(AFCCE) filed a request for a 21 day extension of time to file comments in this proceeding.  AFCCE
argues that an extension is necessary to fully review the technical details raised in the Third DTV Periodic 
NPRM and develop comprehensive comments.  The Request also points out that the Seventh Report and 
Order adopting the new DTV Table of Allotments is expected to be released soon and would inform 
comments to the Third DTV Periodic NPRM.1
3. As set forth in Section 1.46 of the Commission’s Rules,2 it is our policy that extensions of 
time for filing comments in rulemaking proceedings shall not be routinely granted.  However, we believe
that a seven day extension for the comment and reply period is warranted to facilitate informed comments 
to the Third DTV Periodic NPRM, while at the same time maintaining the timing necessary to complete 
the final phases of the digital transition.  Because the Seventh Report and Order and Eighth Further

Notice of Proposed Rulemaking3 has been adopted and will be released on August 6, 2007, a seven day 
extension allows parties additional time to frame their responses to the Third DTV Periodic NPRM in 
light of the new DTV Table of Allotments.  It is essential, however, that the industry and Commission 
remain on track to complete this transition by February 17, 2009.4  Accordingly, we decline to grant the 
full 21 day extension AFCCE requested.
4. Accordingly, IT IS ORDERED that the Request for Extension of Time filed in MB
Docket Number 07-91 by AFCCE is GRANTED to the extent described above.
5. IT IS FURTHER ORDERED that the time for filing comments in the above captioned 
proceeding is EXTENDED to August 15, 2007 and the time for filing reply comments is EXTENDED to 
August 30, 2007.
6. This action is taken pursuant to authority found in Sections 4(i), 4(j), and 403 of the 
Communications Act of 1934, as amended, 47 U.S.C. §§ 154(i), 154(j), 403 and Sections 0.61, 0.283, and 
1.46 of the Commission’s rules, 47 C.F.R. §§ 0.61, 0.283, and 1.46.
