Radio emission from non-magnetic cataclysmic variables (CVs, accreting whitedwarfs) could allow detailed studies of outflows and possibly accretion flowsin these nearby, numerous and non-relativistic compact accretors. Up to now,however, very few CVs have been detected in the radio.  We have conducted a VLA pilot survey of four close and optically-brightnovalike CVs at 6 GHz, detecting three, and thereby doubling the number ofradio detections of these systems. RW Sex, V603 Aql and the old nova TT Ariwere detected in both of the epochs, while V1084 Her was not detected (to a$3\sigma$ upper-limit of 7.8 $\mu\rm{Jy}\,\rm{beam}^{-1}$). These observationsclearly show that the sensitivity of previous surveys was typically too low todetect these objects and that non-magnetic CVs can indeed be significant radioemitters.  The three detected sources show a range of properties, including flaring andvariability on both short ($\sim$200 s) and longer-term (days) time-scales, aswell as circular polarization levels of up to 100\%. The spectral indices rangefrom steep to inverted; TT Ari shows a spectral turnover at $\sim$6.5 GHz,while the spectral index of V603 Aql flattened from $\alpha=0.54\pm0.05$ to$0.16\pm0.08$ ($F_{\nu}\propto \nu^{\alpha}$) in the week between observations.This range of properties suggests that more than one emission process can beresponsible for the radio emission in non-magnetic CVs. In this sample we findthat individual systems are consistent with optically thick synchrotronemission, gyrosynchrotron emission or cyclotron maser emission.
