I recently spent an afternoon working at the Badin Fire Department. No 800 voice equipment was noted.
A member of that department, who also serves with the nearby Air National Guard unit, said his unit had some 800 analog radios, and talkgroups for communication within their unit, as well as with the large ANG unit based on the perimeter of Charlotte-Douglas Airport in Charlotte.
(The Stanly County ANG unit uses Albemarle Airport to train its personnel in air traffic control operations. I believe they also staff the control tower. Periodically, on Tuesdays and Thursdays, military aircraft will practice touch-and-goes at the airport. The runway is 7000 feet.)
