I need help badly programming my PRO-668 into separate playlists, monitoring specific talkgroups only, etc.. You almost need a college degree to learn how to use this piece of crap !!!!! DEFINITELY NOT "User-friendly".This is the worst handheld scanner I've ever owned & this is my 3rd..Back in the mid 90s, they still made very good scanners...Now with Digital Trunking, everything's changed...These Trunking "talkgroups" sound horrible- like they got food stuffed i their mouths when they talk....I personally do NOT like Digital....
