The second part of a search at 1410 MHz for 230 extragalactic objects from the Southern Hemisphere identified as quasars and listed by Veron-Cetty and Veron (1983) is presented. The 30-m radiotelescope of the Instituto Argentino de Radioastronomia (IAR) was used. From observations at different frequencies, the index and curvature of the corresponding spectra were calculated. The 230 quasars cover a sky area from 06 h to 16 h 40 m in right ascension and from -9.5 to -90 deg in declination. All of them are part of a complete sample of 700 quasars.
