Diplomatic Security Service

The State Department now uses P25 Digital transmissions. I have verified this in both NYC and Washington D.C. Note that most of the D.C. transmissionas are also encrypted.

The Diplomatic Security Service (DSS) is a division of the Department of State. The DSS protects high-level diplomats when they visit the United States, except heads of state who are protected by the Secret Service.

Frequencies listed as in use nationwide except in the Washington DC area where they have different uses.
