Greetings folks, this is my first time on the forum here, but I have posted to the various user groups. I am planning on making a long time return to Michigan at Christmas time and plan on bringing a long radio gear, and I am interested in monitoring a system which according to the data base on here is listed as LTR Standard. However, judging by the length of the data bursts it sounds more like a passport system to me. The system of interest is one for the Detroit Public Schools. I will be there a few days before their Christmas Break. I'm also not sure to what extent this system in use because public safety there has a few talkgroups on the MPSCS that is used by the rest of the city services in Detroit, and soon the rest of Wayne County.
