3525 is definitely DPS Austin, Region 6 patrol and Region 7 Capitol Police. 3522 is basically the same thing, sometimes they even both transmit the same things at the same time, sometimes they don't. As far as I know all of APD is now encrypted. UT PD has some interesting things going on sometimes if you have the patience to listen-I leave it on along with other feeds. 3526 is Capitol security guards and a few Region 7 DPS troopers that work inside the Capitol building, but it's not too active. AISD can be interesting if it's working, which it isn't half the time. 2551 is Travis County Constables-they talk quite a bit but their dispatcher goes 10-42 every day at 9 pm
