  We present results from VLBA+Effelsberg 1.7 GHz, VLBA 8.4 GHz and VLBA 15 GHz
observations of the JVAS gravitational lens system B1030+074. The
VLBA+Effelsberg 1.7 GHz data with 3 mas resolution reveal a detailed 60 mas jet
structure in the strong A component of the lens system and maybe a first hint
of the corresponding jet structure in the faint component B. As we go to the
higher resolution 8.4 GHz and 15 GHz data we can see more of the inner
structure of the A core, which is resolved, while the B core still remains
unresolved.
