To expand on what heigtx said above,
Blanco - SO and local PDs are on GATRRS and are clear, fire and EMS can be found on both conventional VHF and GATRRS also clear
Comal - SO and county fire/EMS are all conventional VHF, mostly P25 and clear. NBPD fully ENC, NBFD/EMS/Hospital reports all clear on LCRA.
Hays - Appears to mostly have left OpenSky for LCRA and lots of TDMA use. Most traffic is clear for county LE and Fire/EMS all on LCRA, but SMPD is fully ENC. I don’t recall having picked up any significant conventional activity for any public safety there in quite some time.
Gillespie - LE is on LCRA and can be heard on practically every site within 50 miles of Fredericksburg. Fire and EMS have talkgroups but primary dispatching is done on VHF still. I’ve heard them patched and not patched so program both just in case.
Some extras also:
Bastrop - GATRRS clear for all operations, but you can still hear dispatching and channel assignments on their VHF system.
Williamson - I am least familiar with their system, but I can recall that most fire and EMS can be heard but you’d be lucky to hear any LEOs as they are big encryption lovers there.
