This is an older scanner, but LA County is mostly using older conventional systems all of which can be received by your radio. I never had a 996T, but I do have a 396T which is the handheld equivalent. You should get a programming cable and some software like Freescan. You can then load frequencies from the Radio Reference data base. You will be able to receive LA County Fire, Sheriff and the CHP to name a few. Also aircraft if you are interested in that. The 996 receives some trunked systems. It only does P25 phase 1 digital. However, LAPD is using that so you can receive them as well (may not be in range at your location). If agencies move to the new county wide trunked system you will be out of luck so enjoy the 996T while you can.
