We present optical identifications and radio spectra for ten radio sources from two flux-density-complete samples. Radio variability characteristics are presented for four objects. The observations were obtained on the RATAN-600 radio telescope at 0.97-21.7 GHz and the 2.1 m telescope of the Haro Observatory in Cananea, Mexico at 4200-9000 =C5. Among the ten objects studied, three are quasars, four are BL Lac objects, two are radio galaxies, and one is a Sy 1 galaxy. Two of the sources identified with BL Lac objects, 0509 + 0541 and 0527 + 0331, show rapid variability on time scales of 7-50 days.
