  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 K"uhr 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.
