You best bet is to plunk down $200.00 or so for a FoxPro electronic caller [or $40.00 for several mouth calls] re daytime calling at dawn and dusk; also consider another $100.00 or so for a red spotting light and a bright LED kill light mounted to your rifle scope for night hunting.
Mating howls will work well this time of year. And if you are calving, hunt 100-200 yards in a hide off a fresh afterbirth or dead calf site early/late.
There is lots of info over at www.predatormasters.com
and a posting there re your location will likely result in some responses from KY and OH coyote hunters willing to show you the ropes per a few hosted hunts on your property.
Good Luck and Good Hunting!
