It would make sense for them to move the KCEB signal from the KFXK tower to the KYTX tower. It is rarely a good situation when you are having to rent tower space from a competitor. Moving to the KYTX tower would provide better coverage of KCEB in Nac/Luf and would consolidate their engineering expenses at a single transmitter location.
The cons are the considerable cost to move the transmitter and antenna, plus any utility, building, and tower upgrades that must be done to accomodate the additional transmitter and antenna. Engineering and environmental studies must be completed, and the FCC must approve. Moving the signal farther south would reduce the signal in the city of license, which is Longview, so that may come into play as well.
I am interested to see how this will play out with programming. At the beginning of the process it was said that MYTX 19.2 may move to a subchannel of 54, so that could open the door for new sub-channel programming on 19 and/or 54. Because both KLTV and KETK have abandoned their weather sub-channels, I would like to see KYTX do a either a weather or 24/7 news channel on 19.2 if MYTX moves to 54.2.
