What i have found from research is that DART uses TDMA digital for its OpenSky network. My current scanner, BC355C can not recieve digital so i was thinking of buying a new digital scanner. I would like to know what scanner is needed to recieve DART light rail, DART bus, and DART PD opperations. I am also comfused because i see that DART has two networks Dallas Area Rapid Transit EDACS Narrowband and Dallas Area Rapid Transit OpenSky and i do not know what opperations are on what system.
