OK, I've done enough monitoring here in the Auburn-Opelika area to be able to post the following. This has been speculated on in previous threads. Recently, troopers out of the Opelika Post are regularly using "DPS 2" (Talkgroup 1811) on the Montgomery Metro P25 system. At times, their traffic is simulcast with the VHF channel (155.445/159.030). I've also monitored radio traffic from mobile units out of the Montgomery post on I-85 & I-65 in the Montgomery area on that same talkgroup (1811).
