Radio detectors acting as prototypes of the AERA project at the Pierre Auger Observatory have been used to observe air showers. We present results from a first radio setup consisting of three detection stations running in a fullyautonomous mode and with an independent triggering detection technique. Different stations of a second radio setup have been used to study the emission mechanism. The resulting data sets from both setups confirm the dominant role of the geomagnetic field in the emission mechanism. We present the results of these analyses and discuss how the polarization information is used to disentangle the geomagnetic induced emission from the emission caused by the charge excess in the shower.
