Abstract :
The authors describe the measurements performed at 32 GHz between March and July 1989 on the recently upgraded (64-m) 70-m antenna at Goldstone (DSS-14). These measurements were done on seven separate days using radiometric observations of six astronomical radio sources: 3C274 (Virgo A), 3C273, 3C84, 3C286, P2134+004, and Venus. The aperture efficiency at the reflector set angle of 45 degrees is found to be 0.35+or-0.05 (2 sigma ). The predicted value of efficiency is 0.32 indicating that the original estimates for the radio source flux densities of Virgo A and Venus are fairly accurate. This equates to a gain of 82.85 dBi.<>
