As you may know, In Dayton, While WDTN-DT, WHIO-DT, WRGT-DT and WKEF-DT will be staying where they are after analog shut off -- WPTD-DT and WBDT-DT will be moving their digital stations to their current analog channels(16+26). Of course, since WPTD-DT is out-of core, on channel 58, currently, they HAVE to move in core(channel 2-51) after analog shut off, as ch 52-69 is being reallocated for other uses besides TV.
As you may also know, FCC recently finalized(for the most part) the post-Transistion DTV table of allotments based on the channel election procedure, as well as began their 3rd DTV review proceeding - which is probably the final "major" DTV proceeding related to DTV transistion and analog shut off on Feb 17, 2009. As part of that proceeding, ThinkTV has submitted comments to FCC regarding issues such as the need for them to quickly "receive" a CP for WPTD-DT post transistion on 16, as well as canadian approval(yes, Dayton is in the "Border Zone" and such changes require canadian approval).
I think many folks here may find these comments from ThinkTV quite interesting, as well as hopefully demonstrate just what a major project something like this, and perhaps help some to better appreicate the efforts folks such as the ThinkTV folks have went through to bring us DTV+HD (such as building out a full power DTV station on channel 58 that could ONLY be used during the transistion) ... So here is link to those comments (PDF, requires acrobat reader) :http://fjallfoss.fcc.gov/prod/ecfs/r...ent=6519611248
