BOTTI Centro de Radio-Astronomia e Aplicacoes Espaciais, Escola Politecnica, Universidade de Sao Paulo, Brazil Electronic mail: Iclbotti@bruspvm.bitnet Received 1992 November 20; revised 1992 December 9 ABSTRACT We have observed a complete sample of bright Southern (with the declination 0^deg^ to -25^deg^) BL Lacertae objects and quasars at 2.3, 4.8, 8.4, 22, 43, 90, and 230 GHz. By using statistical methods we have compared the properties of the different classes of quasars to see if there are significant differences in the radio spectrum and variability of these sources.
