Looks like that list is missing the Live Oak 800 site(which is part of the LCRA P25 network) as well as the New Braunfels site. The do have the SAUA 700 mhz P25 system listed. Which is Interesting since no one uses it
If it is Sheriff units they use Kendall 1 and 2 for talk channels normally, if it is BPD units they have "Partol 1 and 2" Also check other sites in they area besides the Boerne site. Check Kendall, Luckenbach etc... the units could only be in range of a certain tower site besides their home site which is Boerne. Could also be a simplex or direct channel that is not listed.
On Public Safety Common 1 Sounds like a Guadalupe County Deputy and dispatch testing the range of the P25 system. Calling out different locations in the county mainly around the county lines. Hope they end up switching. Be a world of difference for interop with surrounding agencies.
