Most VA Medical Centers and Outpatient Clinics are in the 406-420 Mhz range. A few are still in the 162-174 Mhz range. Several have moved to a trunked system.
Here are the ones that I have for Arkansas. They might be outdate.
McClellan VAMC is also on the Little Rock/NLR Pulaski County Trunking System, VA Fire Department dispatch is tested every morning along with the NLRFD pagers. MEMS Ambulance also has a unit assigned with a User Group. See the Little Rock Database on this site for more info.
