We analyze radio continuum and line observations from the archives of theVery Large Array, as well as X-ray observations from the \emph{Chandra} archiveof the region of massive star formation W75N. Five radio continuum sources aredetected: VLA 1, VLA 2, VLA 3, Bc, and VLA 4. VLA 3 appears to be a radio jet;we detect J=1-0, v=0 SiO emission towards it, probably tracing the inner partsof a molecular outflow. The radio continuum source Bc, previously believed tobe tracing an independent star, is found to exhibit important changes in totalflux density, morphology, and position. These results suggest that source Bc isactually a radio Herbig-Haro object, one of the brightest known, powered by theVLA~3 jet source. VLA 4 is a new radio continuum component, located a fewarcsec to the south of the group of previously known radio sources. Strong andbroad (1,1) and (2,2) ammonia emission is detected from the region containingthe radio sources VLA~1, VLA~2, and VLA~3. Finally, the 2-10 keV emission seenin the \emph{Chandra}/ACIS image shows two regions that could be thetermination shocks of the outflows from the multiple sources observed in W75N.
