Ritron, Inc. announced June 10 it has delivered 350 of its American designed and built, NXDN digital locomotive radios to the Southeast Pennsylvania Transportation Authority (SEPTA) in Philadelphia.
Ritron, Inc. noted that SEPTA has the 6th-largest U.S. rapid transit system by ridership. SEPTA is one of only two U.S. transit authorities that operates all five major types of transit vehicles: regional (commuter) rail trains, "heavy" rapid transit (subway/elevated) trains, light rail vehicles (trolleys), electric trolley buses, and motor buses.
The SEPTA order included a mix of Ritron 72VDC and 36VDC powered, one-piece, narrowband analog and NXDN digital capable radios. A number of years ago, the FCC mandated that by Jan. 1, 2013, radio users switch from wideband to either narrowband analog or very narrowband digital radio technology.
