Two Texas TV stations swap channels to avoid interference

Two TV stations in Lubbock, Texas, are swapping their broadcast channels. This change will prevent their signals from interfering with each other.

Broadcast television channels are a finite resource, and interference can make signals unwatchable. When two stations operate too close on the spectrum, one or both can become unusable. This kind of channel swap is a routine way to manage the airwaves and keep local TV viable.
