If you didn't know already, there has been a spectrum auction going on that just ended last week. The outcome of the auction is that channels 38-51 were sold to wireless companies. Therefore, most, but not all, TV stations participated in the auction. Some are not affected, some are having to change channels, some are going off the air and "piggybacking" on another channel, and some are going completely off the air. All information regarding channel changes are to be released by early April, but over on Rabbitears.info
, there's a page devoted to what station is doing what, and I just found out via the "PBS Station" link on that page that WNPT channel 8 will be moving to channel 7. What this means for WRTN-LD channel 7, I don't know. Also, there will not be a change for Cookeville PBS WCTE channel 22. When I find out more information, I will let you know.
