This is probably better suited to the Kentucky page.
That being said, I'm assuming you are using a BCD 536 scanner. Are you scanning the full database and have entered the correct zip code? Do you have the Law Dispatch and Law Talk Service Type enabled?
(I'm using a 536 and receive all KSP I expect to around the Louisville area - Post 4, 5 and 12 along with the VHF frequencies they use at state fair time).
