Interoperability frequency guides

[paulmcg1]

Since the demise of unencrypted RSO radio traffic due to the new P25 system, people have been asking what to program in their scanners.

There are three key government documents that you should look at. These contain frequencies, CTCSS tones, operating characteristics, etc. for interoperability between various government agencies. Because of the need to work with a variety of public safety agencies, these communications are not encrypted. Typically, they would be used during an emergency, they are not for normal dispatch.

(1) Department of Homeland Security "National Interoperability Field Operations Guide" (NIFOG). http://publicsafetytools.info/start_nifog_info.php

Another good tool DHS provides is their Web page that combines the FCC frequency database with mapping software, so you can see what transmitters are near you. You can also download the information as a Google Earth or Microsoft Excel file. http://publicsafetytools.info/NextGen/maps/Location.php

(2) California Emergency Management Agency "California Interoperability Field Operations Guide" (Cal-IFOG). http://www.calema.ca.gov/TechnologyOper ... 0Final.pdf

(3) FIRESCOPE California, "FIRESCOPE Radio Communications Guidelines", MACS-441-1. http://www.firescope.org/documents/publ ... +Documents
