Say Derag2, your PC-7 probably sounds most like a jack rabbit, most long range calls give a more course sound and lower pitch, so what you need to look for is a call that will resemble a cotton tail distress, which will give you a higher pitch and less volume.Really no reason to by a squeeker call, when they get close enough for it you can instead just smack your lips to bring 'em on in.I like open reed calls and I prefer the tweetie call by Verminator calls which can be found at the Randy Anderson web sight, but there are lots of calls that will work, and don't worry too much about sounding just like the tape that you have, I've gone calling with around 10 different guys, and none of them sound like me, we all sound differently, even when using the same calls.Pay more attention to the rythum of your calling, and you will soon pick be bringing coyotes in .Good Luck!
