We have measured the absolute and relative positions of the components of Sco X-1 (Fig. 1) with the VLA from 1980–1986 (Geldzahler, Fomalont, Hilldrup, and Corey, 1981, A.J., 86, 1036; Fomalont, Geldzahler, Hjellming, and Wade, 1983, Ap.J., 275, 802; Geldzahler and Fomalont, 1986, Ap.J., 313, 815). We have used these observations to test the dual-beam model of radio sources proposed by Blandford and Rees (1974).
