It does it very well. Now, when you programmed the scanner, did you put the correct LCN (start with x01, not x00, for frequency 01), AND, press the trunked button and put the talkgroup section in EDACS mode, and enter your talkgroups. It should work very well. And, make sure you have the correct tower site for your area. There are multiple towers in the San Marcos/New Braunfels area, and if you choose the wrong tower, your scanner may seem to not work. Thus, put different towers in different banks, and see what you find.
Happy Scanning.
