During any emergency the National Interoperability frequencies can be the most fascinating and useful frequencies to monitor. Now there is a feed of all the interop frequencies in the Washington, DC area.
This feed uses a Uniden BCD996T monitoring NIFOG (National Interoperability Field Operations Guide), MWCOG (Metropolitan Washington Council of Givernments) PMARS (Police Mutual Aid Radio System), and MWCOG RINS channels. The antenna site for the radio feed receiver is located at the northern most point in Farifax County, Virginia. Keep this link handy the next time things heat up in the DC area.
