We have identified a likely radio counterpart to the X-ray low-mass-X-ray-binary MXB 1730-335 (The Rapid Burster; RB). The counterpart, which is between 4-5.6\sigma away from the X-ray position, has during our five observations shown radio on/off behavior correlated with the X-ray on/off behavior as observed by the RXTE/ASM -- the chance probabilty of an unrelated background source duplicating this is 1.6%. If the radio and X-ray flux are correlated on \simseconds timescales, then observations of radio bursts are well within current instrumentation capability.
