I think there's a lot of good info here. Desert Ram pretty well summed up how I go about it, though I'm all on private land I pull the utv up close behind a big hill and park, climb around/over and set up in the best place I can find with a good view and best concealment. Start calling as soon as everything is set up, everyone is set down and ready.
If I howl to start I will wait a few minutes for any response, then its pretty much continuous with the Revolt, usually 5 to 7 minutes per sound and switch right to another sound with no delay. But recently I started doing shorter intervals, playing one sound for a couple minutes, then alternate back and forth, as if two animals are in a fight. I also have started keeping the Revolt moving continuously in a circle, projecting the sound every direction as two animals would be. It just made sense to me.
I really don't know how important all these details are though honestly. I know you wanted timing info, but no 2 people do it alike, and all here kill coyotes. Far more important is having land with coyotes, preferably ones that don't know the Foxpro sound library by heart, then getting in there without them knowing about it. Quiet vehicles are a definite plus I think like Hellgate said. That being said I don't think a little vehicle noise, in places they are used to hearing it, is a deal breaker. But obviously the quieter the better.
