I went to the AC hunt Saturday. Just before the last hunt of the day my CTX started chattering like crazy. I used noise cancel and it stopped for a second or two then started again. When the crowed passed me it was working smooth again. I didn't have time to change channels in the middle of the hunt. This was the first time I ever used the CTX in a competition hunt. Has this ever happened to any of you on a hunt with the CTX?
