Vandy LIfeflight TGs are in the database.
Doesn't look like Maury Co EMS is explicitly in the DB yet. There is a program in progress where the TN Department of Health is providing TACN radios to every licensed ambulance in TN to facilitate EMS -> Hospital communications. It's live in a few regions, but not everywhere. I'd find the Maury Co hospital TGs and monitor those for new unit IDs, which will likely be local, when monitor those unit IDs specifically to see if they routinely show up on another TG that might be their dispatch. Then again, not every agency is moving their dispatch operations to TACN, they are just moving all EMS -> Hospital communications to TACN.
