Sinclair Broadcast Group (owner of WZTV 17, WUXP 30 and operator of WNAB 58) and Nexstar Media Group (owner of WKRN 2) have made an agreement to rollout a transition for ATSC 3.0. For people who don't know ATSC 3.0, it is the next generation of TV broadcasting. It improves on signal penetration through walls, allows UHD or 4KTV being broadcasted over the air, mobile broadcasting, and much more. What this agreement means, is that let's take WZTV 17 and WKRN 2 for example. WZTV and WKRN will simulcast on each other's channel. Since WKRN has nothing to do for the upcoming spectrum auction and while WZTV will have to change broadcast channels from channel 15 to channel 20, IMO, it looks like the easiest solution is for WZTV to upgrade their equipment for ATSC 3.0 and broadcast both WKRN & WZTV in 3.0 on WZTV's new channel 20 and also broadcast both WZTV & WKRN on WKRN's channel 27. Again, that is just my thinking. I am posting a link to the article below. If you have any other ideas, let me know by commenting below.
