Digital archives of women's radio programming document histories of feminist activism across different eras in multiple global contexts. Mitchell surveys the ongoing development of these archives, examining their role in “re-sounding” women into history. Women's radio can be a place for individual empowerment, expression and creativity, as well as a space for collective and transnational feminist campaigning and activism. A case study of Fem FM women's community radio archive in the UK demonstrates how archives of feminist radio activism become both a repository and a maker of cultural memory.
