I'm working on making systems for each county in Arkansas so I can use location based scanning. Problem is, I can find talk group data for the following counties but no tower site data. Maybe some of them use adjacent county tower sites? Any help / info would be greatly appreciated!

Calhoun
Carrol
Chicot
Clay
Cleveland
Conway
Desha
Howard
Izard
Lafayette
Lee
Monroe
St. Francis
Sevier
Sharp
Woodruff
