I recently acquired this scanner for my birthday. To save time in programming it, I uploaded (and renamed) a 536HP file, which contained two LTR systems. The 536 had received these systems fine, but now my SDS200 seems to only be picking up talkgroups saved in an "Unknown TGIDs" department. I have another department that I created for identified talkgroups, but it doesn't seem to be "seeing" those. In other words, it is only picking up talkgroups saved into the "Unknown TGIDs" department and not the other. It also is giving random bursts of static after transmissions. I've looked over the file again and again in Sentinel, but can't find any issues. Is this some sort of weird compatibility issue between the 536 and SDS200 or something else?
