I think Nomercy hit it on the head, if it's distorting, that's not too good, the sound needs to be natural.The country where I call is very open, so I start all my sets blowing about as loud as I can, may start with a cottontail call first and then go to a louder jackrabbit call, but I blow loud from the get go. I have never seen one run away from me, so as far as I know I haven't "blown one out of the country" so to speak. Just a week ago I back tracked one to its bed, where it was laying when I started calling, and it was only maybe a little over 100yrds. from me when I started calling, which, there is no doubt in my mind that I was very lucky that I didn't bump him before I set up and started calling.I've had a few times that I saw the coyote before calling, and called only loud enough for it to hear me, than once I shot it, then I cranked up my volume, to try and reach other coyotes in the area.
