FWIW - While on my way into work this morning, about 0630 on I-65 in Autauga County, I picked up a brief transmission on 159.210, DPS' special ops/detail frequency. Unlike the other times i've picked this one up, this transmission was P-25 digital, with a NAC of 137. The transmission was brief, and very garbled like I was at the end of the reception range, so I couldn't make anything out.
