No. It's not contour interference that's the problem as a second adjacent. It's the mere existence of WWSK.So can WWSK go directional with a null to the west in order to allow WXBK to move to Empire?
And before anyone says, "just pay them to surrender the license". It won't work. The FCC will keep the allocation alive and put it into a future auction and WXBK would need to protect the vacant allocation. @fybush can explain this in more detail.
