Justice Knowles asked why the public cannot hear the police scanners. It was mentioned that they are not encrypted but that they are digital scanners, not radio scanners.
Yes there are many types of digital like NXDN, DMR and P25 to name some of some them used in public safety or business radio systems. Both DMR and NXDN are separate paid upgrades on your model of scanner. P25 is included already.
Most public safety uses P25, many also use NXDN or DMR.
Digital scanner, radio scanner or police scanner are all different names used and most often they really mean the same thing.
Based on original post in this tread I have already told you what is needed for your 536 to decode this channel. That is way DMR is shown with slot, color code, and talkgroup. All them are required to listen to DMR. Even if don't have all of information you can just enter the frequency after the DMR upgrade and scanner will discover the information.
