We present radio continuum data for 1050 B3 radio sources at 10.6 GHz. These sources constitute the B3-VLA sample which is complete down to 100 mJy at 408 MHz. The aim is the construction of a homogeneous spectral database for a large sample of radio sources, 10 times fainter than the Kühr et al. (1981) sample, in the range 151 MHz to 10.6 GHz. Extended and complex radio sources (53) were mapped; the remaining ones were observed with cross-scans. We detected 99% of the radio sources with a flux density error of about 1 mJy for the fainter ones. The analysis of the quality of the 10.6 GHz data is presented.

Key words: radio continuum: general, galaxies: general -- quasars: general
