So conditions are kind of favorable once again tonight and I began hearing what I think is London PD again. I programmed in their P25 system :
London Public Safety Trunking System, London, Ontario - Scanner Frequencies
and I've been hearing mainly PD talkgroups, 145, 146 with radio IDs in the 27xxx area and one in the 21xxx area. Trouble is, some is encrypted, some not. Then I thought I heard them say wyandotte hospital, and that's in Wyandotte Michigan not far from me. I just played back the audio file and they definitely said "this is bravo 205 requesting priority 3 traffic to wyandotte hospital".
So I search for the CC (866.464) frequency for the London west site I have programmed in, which is also used in my local Windsor P25 system, and turns out its also used in the massive Michigan Public Safety Communications System. It pops up in many sites there:
Michigan Public Safety Communications System (MPSCS) Trunking System, Statewide, Multi-State - Scanner Frequencies
So my question is this. Last night I saw these TGID/RID's from London pop up while 'searching' (wildcard) on my gre psr800 for my local windsor system. How did they pop on to my local system though? Now I'm seeing London proper TGID's, yet feels like the Michigan system is piggy backing on their transmissions. I thought you would need proper encryption keys to talk on another system though and meet other requirements of the system like step, system ID, site ID and such. Their TGIDs are right for their own systems though, they aren't talking on my system but I can still hear them on it.
I know conditions have been making a mess of things lately, but seems I don't get why I was seeing London TGID's on my Windsor system, and now hearing Wyandotte Michigan on a programmed London system. The London system I have in isn't even in search mode (wildcard), its just scanning the TGID's from the London Public Safety system. Yet audio from Michigan seems to be entering into both London and Windsor's P25 system.
Very confusing. I'm just wondering if someone can explain why this is happening?
