  We present multi-frequency radio observations of a sample of z~2 obscured
(type-2) quasars in the Spitzer extragalactic First Look Survey area. We
combine the public data at 1.4 GHz, used in the selection of these sources,
with new observations at 610 MHz (GMRT) and at 4.9 GHz (VLA). We find the
sample includes sources with steep, flat and gigahertz-peaked spectra. There
are no strong correlations between the presence or absence of emission lines in
the optical spectra and the radio spectral properties of the sample. However,
there are no secure flat-spectrum type-2 quasars with narrow emission lines
which would be problematic for unified schemes. Most of the population have
straight radio spectra with spectral index alpha~1 as is expected for
developed, potentially FRI-like, jets in which continous injection of
relativistic electrons is accompanied by inverse-Compton losses against the
cosmic microwave background.
