  Radio emission from non-magnetic cataclysmic variables (CVs, accreting white
dwarfs) could allow detailed studies of outflows and possibly accretion flows
in 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-bright
novalike CVs at 6 GHz, detecting three, and thereby doubling the number of
radio detections of these systems. RW Sex, V603 Aql and the old nova TT Ari
were 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 observations
clearly show that the sensitivity of previous surveys was typically too low to
detect these objects and that non-magnetic CVs can indeed be significant radio
emitters.
  The three detected sources show a range of properties, including flaring and
variability on both short ($\sim$200 s) and longer-term (days) time-scales, as
well as circular polarization levels of up to 100\%. The spectral indices range
from 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 be
responsible for the radio emission in non-magnetic CVs. In this sample we find
that individual systems are consistent with optically thick synchrotron
emission, gyrosynchrotron emission or cyclotron maser emission.
