Direct measurements of the Josephson radiation emitted in X band from a superconducting thin-film microbridge coupled to a resonance cavity are reported. Power is emitted if one of the harmonics of the Josephson frequency is in the bandwidth of the receiver. The maximum power emitted during the experiment was 10$sup -13$ W. The Josephson radiation could easily be detected at frequencies off resonance. (AIP)
