It is argued that collective interaction of electrons and positrons with an ambient interstellar magnetic field can generate radio bursts powerful enough to be detected from anywhere in our Galaxy, or even beyond. A better method, based on this argument, of searching for black-hole explosions by trying to detect linearly polarized radio-frequency pulses, rather than gamma-ray pulses, is proposed. To show the potential advantage, the gamma rays from a fireball with Lorentz factor = 100,000, situated within a distance of 1/100 pc, would only be registered by a detector of effective area 100 sq cm whereas even a crude nondirectional antenna would detect the corresponding radio pulse at distances of approximately 10,000 pc. An Arecibo-type telescope could detect such pulses, each triggered by a single entity of subnuclear size, from as far away as the Andromeda galaxy.
