Abstract
Some results are presented of a successful attempt to correct the surface manufacturing errors on the secondary mirror of the Noto 32 m radiotelescope by means of a new primary mirror, the shape of which is controlled by 244 electromechanical actuators. During a 43 GHz Jupiter observation, the technique yielded a 22% gain increase.
