It has previously been suggested that the explosion of a primordial black hole (pbh) might produce a coherent radio pulse detectable at a distance of some 10,000 pc with a simple antenna. Negative results of several all-sky searches for coherent radio pulses arriving from random directions in space are used to place upper limits on the pbh radio-pulse emission rate per unit volume. A general analysis of limit criteria is presented, effects of the interstellar medium on the pulse time scale are considered, and the factors that determine the optimum search strategy for pbh radio pulses are examined. The results show that the best known radio limit could be improved at least a million times with present-day techniques, that this existing limit is already about 80 times better (99.5% confidence level) than a suggested limit for the optical region, and that the existing radio limit is 10,000 to 1 million times better than the pbh explosion-rate limits obtained from gamma-ray observations.
