Able to hear KHP Troop A, B, H and G [KHP] dispatches on the KSICS system without issue via my Whistler scanner on the discone antenna here in southern JoCo.
As your location states Osawatomie, KS (hilly area)... the nearest KSICS tower near you would be the Paola, KS tower (north). Next up would be the Parker, KS KSICS tower (south).
