Well, I just now found out the final layout of the 3.0 setup: where 1.0 channels will go, which broadcast channels will go 3.0, etc. WNAB's RF channel 30 will become the second 3.0 station in Nashville. It will broadcast WKRN's and some of WZTV's 3.0 channels. In return, WKRN will broadcast WNAB's 1.0 58.1 CW programming, while WTVF will broadcast WNAB's 1.0 58.2, 58.3, and 58.4 progamming. So, it looks like WZTV will split up its 3.0 channels. Some will go on WUXP's 3.0 station while others will go to WNAB's 3.0 station. It is all listed below as it will be on June 23rd after 10am. The (1) and (2) next to WZTV just means that it is split up. I don't have any information where WZTV's 3.0 channels will individually end up. If you have any questions about any of this, please feel free to either comment below or contact me by going to the contact page here. Until more news breaks, that's all for now.
