Coherent tunable microwave radiation (2--18 GHz) has been observed from two microbridge Josephson junctions coupled by a shunt resistor. The coherent power (approx.4 x 10/sup -12/ W) is nearly four times the power emitted by a single junction. The linewidth of the radiation in the coherent state is one-half that from the individual microbridges.
