Only recently have we had telescopes with sufficient sensitivity to detect cataclysmic variables (CVs) at radio wavelengths. I briefly review the properties of the observed radio emission of non-magnetic CVs and discuss the possible emission mechanisms. Furthermore, I highlight cases where CV radio studies could enable progress on broader astrophysical contexts. Given the sensitivity of new and planned radio telescopes, CVs are likely to make a significant contribution to the population of galactic radio transients in future surveys.
