Scientific paper

We present results from EVN and MERLIN observations of the OVV quasars 3C216 and 3C446. The structures of these quasars are mapped with EVN on the 10-300 mas scale and with MERLIN on the 80 mas - 1 arcsec scale. In 3C216 we have found a 140 mas long, steep spectrum jet extending from the core in PA 153 deg, almost perpendicular to the outer arcsec scale structure. At the end of the jet there is a bright knot, followed by a sharp bend towards the direction of the SW outer lobe. The entire structure is embedded in a low frequency halo ca. 8 arcsec in extent. In 3C446 a 320 mas long curved jet has been mapped in PA 113-90 deg. At the end of the jet a similar sharp bending has been found but without a bright knot. In MERLIN maps there is evidence of an additional north-pointing extension of the core, and also an extended low-frequency halo as in 3C216. We point out the morphological similarities between 3C216, 3C446, and other sources of the Compact Steep-Spectrum class.
