There must be some tropo this morning, I'm listening from 40 miles south of Fort Wayne, IN. I'm hearing a P25 channel on 453.151 NAC:151. TG 1 sounds like some kind of roadside assistance. They're talking about disabled vehicles on the Dan Ryan Expressway. So far I haven't been able to find a P25 listing for this frequency. I don't have a system ID. Anybody know which radio system this may be?
