In all my years in the scanner hobby, I never once confirmed hearing the Greyhound Bus (nationwide company). I know their two local dispatch centers are at Newark Penn Station and Port Authority in NYC. Do they even use radios or just cell phones? According to the FCC database, their last license expired in 2005 and they once used frequencies in the 451 MHz band. So it seems they either use cell phones now to communicate, still use their old radios even though their license expired, or perhaps listed under another name now. Does anyone have info on this?
