Sometimes you have to take maps made to promote sales with a grain of salt...
... though CKLW's map was pretty dead on for Ohio. WJR was the weaker of the 2 at my Ohio location but they were even in Lima
Lima is located at roughly the same distance, and along roughly the same radial to/from both WJR and CKLW. The location of Lima is rather well up on CKLW's major daytime lobe toward the SW, so for that ~107 mile distance and regardless of the real ground conductivity, CKLW could reasonably have somewhat greater daytime field intensity there than WJR.
Below are the groundwave values for both facilities in/near Lima, based on the FCC M3 map.Daytime
CKLW 1.99 mV/m
WJR 1.44 mV/m Nighttime
WJR 1.44 mV/m
CKLW 0.35 mV/m
(edit) added the distance
