Some of the talk groups such as the Houston High Intensity Drug Trafficking Area are marked on this site as encrypted, but I hear some radios that are not. I will usually hear one or two radios and the rest will be ENC........so I will hear only bits and pieces of what is going on. I wonder if this is an error on the radio techs end or if they just don't bother to encrypt all the radios on those talk groups. I worry that we will be experiencing this on the primary dispatch channels once they are switched to P25. From what I hear this is happening in other parts of the county. I will say I have not seen this with Montgomery or Austin counties.
