The DFW Ham Radio Interoperability group was establish by the DFW cross county Bioterrorism/Public Health Emergency Preparedness meeting on April 8th of 2011.   One of the concerns of this group was that while each county had a relationship with the Amateur Radio community,  some had a better working relationship than others and the operating practices of each county were different.  The Cross County group decided that a group needed to be established to work out common practices, procedures, and working relationships so they could support each other if the need came up.   The initial group was focused on Health / MRC issues.   Since then the group has been asked to consider operations other than Health / MRC.   This groups meets monthly and reports to the DFW cross county Bioterrorism/Public Health Emergency Preparedness group.
