I thought there was an RR page for the city. That was specifically a DMR system. The only 'mention' I can find of the city. Is on RR's Alamance County page.
A couple years back, I picked up DMR in Burlington, but never mapped it out. Sounded like possible public safety, not sure. Was messing around with my SDR and picked it up. Definitely wasn't being used alot at that time.
