Using both MERLIN and the VLA, we have succeeded in detecting the radio emission from three components in WR 146: the WR star, the wind-wind collision region, and for the first time, the stellar companion to the WR star. This allows the unique possibility of determining the mass loss rate ratio of the two winds, an important observable that is independent of distance.
