  • Public Notice implementing the DTV Delay Act.

    Spreadsheet listing all analog stations and their signoff plans.

    Spreadsheet listing stations that will be tentatively denied permission to go off on the 17th.
    Public Notice on the disposal of requests to continue to go off on the 17th.

    Spreadsheet of 53 stations which certified they will meet/have met the 8 criteria for continuing to silence their analogs on the 17th.

    Spreadsheet of 10 stations which have attempted to show they face extenuating circumstances that require them to go off on the 17th. The FCC has not yet ruled on the validity of their showings.

    Spreadsheet of 43 stations which have given up on signing off on the 17th and will remain on until June.

    All 106 of these stations are reflected in the condensed document below.
    A condensed document showing analog stations and their signoff plans. WARNING, this is a rather large file. (around 1.6MB)

    Many stations have not only notified the FCC of their plans to sign off on time, but they've been notifying their viewers. Stations are now required to do so. Stations are required to note that their February 17th signoff date is in advance of the new final deadline of June 12th. Such stations are also required to, between the 10th and the 14th, air a notification crawl for 5 minutes every hour. On the final two days - the 16th and 17th - the crawl must air for ten minutes.

    The Notice does not allow stations whose post-transition DTV facility differs from their pre-transition facility to use that post-transition facility between February 17 and June 12. Stations wishing to sign off on February 17th must either be using the same DTV facilities pre-transition and post-transition, or must obtain a STA before activating their post-transition facility.

    Stations that do plan to sign off on February 17th are encouraged to provide "nightlight" service for at least two weeks following the 17th.

    Finally, the Commission is permitting those stations which have already silenced their analogs to return them to the air, for part or all of the February 17 - June 12 period. They must file a STA request to do so. At least one station (WSUR-9 in Puerto Rico) has done so; another (on the mainland, I don't remember which!) has filed paperwork to return to full-power analog operation, after having reduced power in anticipation of switching to DTV on its existing channel.

  • The DTV Delay Act HAS PASSED BOTH HOUSES OF CONGRESS. One can assume President Obama will sign it.

    This bill does not require analog stations to remain on until June 12th, but it does allow them another four months. Unlike the "Analog Nightlight Act", the "DTV Delay Act" allows stations to air any programming during the additional four months.

    It requires any analog stations wishing to sign off on February 17th as scheduled to meet existing FCC requirements - which require 30 days' notice to the FCC, and to viewers. (in the form of a "crawl" on the screen)

    Of course, there are only 12 days left before February 17th. Many stations had already begun notification, in anticipation of this bill being enacted - but most of them didn't begin until less than 30 days before the 17th either. Really, this bill wasn't on the table until after January 17th. I think most of these stations believe the FCC will agree that the 30 days' notice should be waived given the late enactment of this change.

    This page lists all stations which have filed notification of analog signoff on or before the 17th.

  • The FCC has created a "Replacement Digital Television Translator Service". The new service is technically identical to the digital LPTV service, except that coverage is limited to the service area of the associated analog station. (stations can still seek regular translators to expand their coverage, but those applications would not receive priority processing.) Replacement Digital Translators receive priority over all other LPTV/translator applications except those for displacement of existing LPTV/translators from their existing channels. (Replacement Translators have co-equal priority with displacement applications) Replacement Translators are in theory receiving regular letter-number callsigns like "K20AA-D", though confusingly they're showing up in the FCC database under the calls of the primary station being relayed...

  • Congress has passed, and President Bush has signed, the Short-term Analog Flash Emergency Readiness Act, and the FCC has proposed an "Analog Nightlight" program to fulfill the Act's requirements. It is unclear what effect the DTV Delay Act will have on Analog Nightlight. The "Analog Nightlight" program would allow many stations to leave their analog transmitters on the air for 30 days after February 17th, broadcasting public safety and DTV transition information to those stragglers who haven't upgraded to DTV in time. Appendix A lists 310 stations in 136 markets and 46 states which the FCC believes are eligible to participate in the program. They strongly suspect more stations would be eligible than those listed. (for example, the station I work for is not listed -- but I see no reason why it shouldn't be eligible) Stations listed in Appendix A are automatically eligible to participate but must file a "Legal STA" to notify the Commission of their intent. They must file by February 10th. Stations not listed must file for an "Engineering STA" by February 3rd. The proposal indicates the information broadcast "...should be available in both English and Spanish..." - apparently regardless of what language the station normally broadcasts in. Broadcasts in other languages are encouraged where appropriate. (for example, Asian languages in the San Francisco area) Only emergency and DTV transition information may be broadcast, and no advertisements are allowed.
