The original DTV plan, IIRC, was to vacate the VHF band in all markets and to auction that spectrum. However, as you say, an insufficient number of UHF channels were available to satisfy that need, particularly during the transition period. Therefore, it was necessary to temporarily utilize many out of core UHF DTV channels. The FCC, after learning that the VHF band had very little auction value, also made a number of high band VHF DTV assignments in congested RF areas. Additionally they also allowed broadcasters the option of retaining VHF channels for DTV service, where technically feasible. I'm too lazy to do the research but I do imagine, as you say, that there will indeed be some all UHF markets that were once primarily VHF. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
