Hi Corey
Welcome to the board.
The question you asked is hard to answer, because a coyotes hearing is way better than a humans. The sound can be much louder to them at 1/2 mile than it would be for us.
I hunt in the same state you do. My experience is to call every half mile if your calling in timber. Maybe up to a mile if your calling large open fields.
I hunt mainly along the S. Skunk river and try to leave a hundred yards or so of open field between me and the timber I am calling. I do not call loud very often, unless there is a breeze, even at that, I try to set up so the breeze will carry the sound toward where I think the coyotes will be hanging out.
I have had coyote respond almost instantly, and some, I have had come in after 20 - 25 minutes. Chances are they ran along ways to get to the sound.
Too answer your question, I would assume a call will carry up to 3/4 of a mile, give or take a 1/4 mile depending on volumn, terrain, and weather.
Best of luck, hope I helped.
