In addition to the previously detected HW object, radio emission is now reported from six Herbig-Haro objects in Cepheus A West (GGD 37). The radio proper motion of one object has been measured. In general, there is a displacement in position of the stronger radio and H-alpha objects, and this, together with H-alpha and H2 observations by others, enables some of the properties of the 'working volume' of the radiative shock producing them to be defined; it also enables a description to be made of the interface where it is suggested the high-velocity (about 1000 km/s) stellar wind is converted to the lower velocity (about 20 km/s) molecular outflow, and to define the direction of origin of the shock. The only other HH objects from which radio emission had been detected previously are HH 1-2, and more recently HH-80-81.
