N7C is a Special Event Station commemorating the Navajo Code Talkers, who served heroically and decisively in the Pacific theatre of World War II. N7C is activated every year around the federally designated Navajo Code Talkers Day, August 14 - this year the SES runs from August 10 through August 15.
