sapper--First, do your scouting and make sure there is some coyote sign in the area.
Then, I have a couple of things I would urge you to think about before you go blasting on your howler as the first tune you play: What's going to happen if there's a coyote or two within a 100 yards or so of your calling stand? And to further add to the mix, what if one or all of those coyotes are young ones born this year? They might just as well turn tail and run away from your stand as come running to whip up on the intruding upstart.
I'd urge you to start with a low volume prey distress call for 3 or 4 mintues; then increase the volume a bit for the next 3 or 4 minutes. The length of the distress sounds can last 30 seconds or so and then maybe a minute or so of silence; then 30 seconds to a minute of distress sounds, then silence. Use that sequence for the first 8 to 10 minutes. That way, if any predators are real close, you won't be blasting their ears out with your coyote howling. Then, if nothing comes in, go ahead and start with the howling. I'd also recommend you stay on stand for at least 25 minutes or maybe 30 minutes if you go my recommended route.
