Prince George’s County Public Safety Communications flipped the switch this morning ending the simulcast of the Fire/Emergency Medical Services (EMS) Department which is now fully operational on the County’s upgraded 700 MHZ TDMA radio system. Over the past several months Fire/EMS apparatus have had the new radios installed and portable radios distributed to stations and support personnel. The Fire/EMS Department has been simulcasting over both the old and new frequencies during the transition period that ended just before 8:00 am today. The Fire/EMS main dispatch channel will be the only channel that can be monitored on conventional scanners on VHF 155.685.
Monitoring of the 700 MHZ TDMA frequencies is currently only capable on a GRE PSR-800 scanner that is available at select retailers. Please keep in mind that this not an endorsement of this particular scanner, however, it is the only commercially available scanner capable of monitoring our new frequencies.
There are also web based sites that may continue to provide the ability to monitor PGFD frequencies. Again, this is not an endorsement of these sites, rather, a recommendation to be able to continue monitoring our frequencies. These sites includes:

The 700 MHZ TDMA radio system and public safety communications are part of the County Office of Homeland Security. Prince George's County Public Safety Communications Center (PSC) is the Public Safety Answering Point (PSAP) for Prince Georges County. This means that all 911 calls in Prince Georges County are routed to the center for dispatching of proper emergency personnel. PSC consists of approximately 190 authorized personnel that are responsible for all aspects including call taking, dispatching, technical support, radio system, and personnel functions. Any questions concerning the new radio system should be referred to Public Safety Communications administration.
