Listen live to the entire Washington DC Fire, EMS & City Services radio system. Unlike other Apps, you can listen to every talkgroup on the system. All of the transmission are archived, so you can quickly find and listen to past calls.The system uses a Software Defined Radio to capture the trunking control channel, which announces new calls on the system. A recorder is then spun for each transmission, making sure nothing is missed.
