We discuss 6 GHz JVLA observations covering a volume-limited sample of 178 low-redshift (0.25 mJy beam{sup −1} (log(L)≳24). The radio luminosity function of optically selected QSOs and the extended radio emission associated with RLQs are both inconsistent with simple “unified” models that invoke relativistic beaming from randomly oriented QSOs to explain the difference between RLQs and RQQs. Some intrinsic property of the AGNs or their host galaxies must also determine whether or not a QSO appears radio-loud.
