TV Frequency Changes Mean Antenna Users Need To Rescan

If you get TV over the airwaves (not cable or satellite), you'll need to re-scan the channels next week.
If you get TV over the airwaves (not cable or satellite), you'll need to rescan Friday to keep Charlotte's public TV channel.

A three-year project to reallocate television broadcast frequencies nationwide is finishing up, and that means changes if you get TV using an antenna. 

On Friday at 12:30 p.m., WTVI PBS Charlotte will become the final station in the Charlotte area to make the switch. Eleven other Charlotte-area stations made the change last fall.

It doesn't affect the channel number, but if you rely on an over-the-air signal instead of cable or satellite, you'll need to rescan your TV Friday afternoon in order to continue receiving the channel.  

It's part of a federal effort to open new spectrum for high-speed wireless services.

For more about the change and how to set your TV to rescan the channels, visit https://www.wtvi.org/news/plan-to-rescan/ or https://www.tvanswers.org/.
