Hello, I am trying to find a way to find new systems in my area (or distant systems). I have been using unitrunker with my prs500 to monitor programmed systems but when I search 700 and 800mhz ban it will stop at the control channel but not "decode." Is there a way to decode or tell me what system it is when using the search feature? the only info I see is a 3 letter/number that flashes up next to the frequency. Thanks
