I can say, that I'm very, very familiar with the west desert area. Very. And I haven't bothered to day time call out there in a lot of years. Although I still get out there often, doing other things. And was getting out there for some night calling on occasion a few years ago. The night calling was just okay. The day calling has just mostly sucked pretty bad out there for decades now. Don't get me wrong, you can always come upon a few sets of fresh ears and have a good morning or a good day or even a good weekend. But that would be the exception to the rule.
What you experienced. Yappers. Is the rule out there, not the exception.
I call quite a bit differently than you describe. But who is to say my way is any better. I get the volume up quite a bit higher, quickly, and let it run continuously. I turn the volume down towards the end of the stand, not the beginning. That's just me. This time of year I don't bother with vocals much, except for locating. Most coyotes aren't and aren't ever going to be territorial. Moving on yappers can be quite productive, I think that was a good play. It just didn't pan out that time. The way it goes.
