Finding Coyotes this time of year is the main thing. By that...knowing where they are, NOW.
With small game, Archery, Turkey hunting, Bear hunting, Corn and Beans being taken off, there is much activity in the woods and fields. Human pressure displaces Coyotes.
Don't think Coyotes are here just because your neighbor's friend has a uncle 'that hears 'em howling all the time' on his farm. Keep scouting in-season to keep tabs on Coyotes. Check the dense cover for sign.
What I'm getting at is we may be calling to Coyotes that have been somewhat pushed out. It may not be the sounds you are using, so don't beat yourself up. Reason things out, look for sign and use your woodsmenship. If Coyotes are in front of you, they will respond.
On the other hand, if you know Coyotes are here NOW and they don't respond...you maybe missing a simple detail or two on set up or approach.
Sometimes changing sounds or changing set up will help.
Don't make calling harder than it is. Keep it basic, think things out, have a plan.
