I just made a new electronic caller and am looking for anybody that has coyote or crow calls on MP3 format. I just bought Johnny Stewarts Predator Calling tape set and have been happy so far, however $10 plus seems a bit much to pay for a tape or cd. Does anybody out there have any of these calls on there computer or does anybody know where I could possibly download some for free. I know you can make your own via the instructions at www.predatormasters.com but I don't know where to find any sources.
