I tried it on my scanner through the full database just to see if it'll pop up and it did not. The TxWARN system did but LCRA didn't. Here's the file.
Looking at your file, while you have the talkgroups used on both the TxWARN and LCRA systems in your departments, you have none of the sites (for the two systems) that are in the county.
I have attached a file with the two trunked systems. along with their Sites as well as Departments. Also, you indicate that your friend moved to Nacogdoches to attend SFAU, but none of the channels & talkgroups associated with the school were included. I included those, as well as also adding the conventional (non-trunked) frequencies listed for various county entities in case some of them might still be active. The small town VFDs may well still use their conventional channels, in lieu of spending the money required to issue everyone a radio compatible with the trunked systems.
These were imported via ProScan to ensure that location data was present. I did not set the updated list to use location control, but you (or he) can do so after adding the file to your favorites lists.
