Havent heard anything of being switched, other then the new place they are moving into. It could be possible they are on the windsor public safety system now. Or they could have the same freq as they use now, just may be digital.
Do you run any programs like unitrunker or anything?
Can always load up DSD and park the scanner on their voice channel and when you hear the digital sound DSD will tell you what it is, P25, TRBO, NXDN n so on
Ill run unitrunker here through the week and see, and I'll have a listen as well.
