The reported investigation is the continuation of a study conducted by Ledden et al. (1980). Flux densities at 1.415 GHz and 4.755 GHz along with the spectral indices for the extragalactic sources are presented in a table. The 1.415-GHz flux densities were measured with a 305-m telescope in Arecibo, Puerto Rico during December 1979. The left- and right-circularly polarized outputs of the phase-correcting line feed were connected to independent receivers, each of which had a 150-K system noise temperature over a 40-MHz bandwidth centered on a 1.415 GHz. The detected outputs of both receivers were averaged to yield total intensity and recorded digitally for later analysis. Attention is given to the spectral index distribution, and a comparison of the data with evolutionary models is conducted.
