I jest got my pro-107 need to know how to make it scan what I programmed to the SD card? Like my old scanner I could hit the scan button and it would scan the programmed frequencies. What can I listen to in Cleveland county using this scanner I was hoping to listen to fire ambulance business retail security and safety no like the cops? Just got this scanner in from eBay in having a little bit of trouble figuring it out and programming it I know it may not be digital but does it do trunk cracking or can somebody give me some insight to tell me if I wasted my money.
