Whitehall PD Radio
Hi, I see you live in Whitehall. Whitehall PD, as well as Reynoldsburg PD, use the old UHF frequencies, not a trunked system. You could pickup a used conventional scanner on ebay or craigslist for around 20 bucks and listen to them directly. (Whitehall - 460.2500, Reynoldsburg - 460.3000 & 460.3750).
Check out the database for Franklin County and surrounding areas, and see what else you could listen too on conventional. Fairfield and Licking Counties have some interesting traffic too. You are also close to Port Columbus Airport and could listen to air traffic. Enjoy.
