We have searched 11304 quasars from the NVSS catalog for radio emission and obtained 2626 positive detections, of which 301 are new radio detections. We made statistical studies of the radio spectral index, radio luminosity and the fraction of radio-loud quasars versus absolute B magnitude and redshift. We found that the fraction rises between M_B_=-22 and -30 and that it increases at z=0.0 until z=0.8, then goes down at z=1.5. The degree of polarization shows no dependence on redshift.
