I have a radio shack pro 2052 desktop scanner. The problem is that no matter what I do, it refuses to search for talkgroups. I cannot get it to search or even program talkgroups. Does anyone else have this problem? I dont know much about this scanner and any help would be great!. If anyone wants to know, the system I am monitoring is the Milwaukee public safety type 2 smartnet system if that helps at all.
