True, but W298BI's signal overlap still reaches towns like Lamar, Bishopville, Timmonsville, Hartsville and Lynchburg, some of which extend into WNKT's 50 dbu contour and W298BI has a non-directional signal, a directional signal would help with this...Still, it probably wouldn't matter as perhaps almost no one is listening to WNKT anyway.
Even with a directional signal away from Columbia, W248DD (97.5) causes interference in Union SC where WCOS should have a 60 dbu signal, but now its unlistenable there.
