Abstract: We report multi-frequency circular polarization measurements for the four extragalactic radio sources 0056-00, 0716+71, 3C 138 and 3C 161 taken at the Effelsberg 100-m radio telescope. The data reduction is based on a new calibration procedure that allows the contemporary measurement of the four Stokes parameters at different frequencies with single-dish radio telescopes. We are in the process of framing the observed full Stokes spectra within a theoretical model that explains that the level of measured circular polarization as Faraday conversion.
