Seems like we've been hearing less and less on our scanner over the last year or so. Is this due to them changing systems possibly? Or, maybe we need to re program?? I have no clue how to set it up, I purchased this scanner for my husband several years ago for Christmas and he has been complaining for months that he isn't hearing what he used too on it. It is a Pro 96 from Radio Shack, they programmed it for me when I bought it. Any thoughts??
