We present the first milliarcsecond-resolution radio images of a radio-quiet quasar, detecting a high brightness temperature core with data from the VLBA. On maps made with lower frequency data from MERLIN and the VLA, jets appear to emanate from the core in opposite directions which correspond to radio emission on arcsecond scales seen with the VLA at higher frequencies. These provide strong evidence for a black hole-based jet-producing central engine, rather than a starburst, being responsible for the compact radio emission in this radio-quiet quasar.
