WSGS currently has the best FM signal in Kentucky IMHO (better than the Owensboro stations). The only station that rivals it is WSIP/Paintsville.
In terms of distance to the protected 60dBu contour, WSGS indeed currently has the best FM signal in Kentucky.
Among the nine Class C and C0 stations in the state:
#1: WSGS 100kw/446m 83.1km
#2: WQHY, WSTO, and WVVR tied 100kw/305m 72.8km
#5: WGGC 100kw/301m 72.5km
#6: WBKR 96kw/305m 72.3km
#7: WKDQ 98kw/300m 72.2km
#8: WUKY 100kw/237m 67.2km
#9: WEKH 31kw/324m 62.4km
WSGS's permit is to reduce antenna height to 362m. It would continue to have the largest 60dBu contour, at 77km. However, WVVR (100.3 Hopkinsville) also has a permit to
increase antenna height to 451m. That would increase its 60dBu contour to 83.5km, making WVVR the biggest signal in the state.
(nearly half of WVVR's coverage area is, and would remain, in Tennessee)
FWIW, WSIP is a class C1 operation with 94kw/183m. Due to the low antenna, their 60dBu contour extends only 61.6km.
None of these contour figures take terrain, population, or state lines into account. I would suggest stations in Eastern Kentucky reach greater distances for listeners in elevated locations, but much shorter distances for listeners in low locations; coverage for stations in Western Kentucky is far more consistent due to the flatter terrain.
