The recent data of the decametric survey carried out in Grakovo with the UTR-2 radio telescope and the data of a number of higher frequency surveys have been used for constructing the spectra of 147 discrete sources in the frequency range 12.6-1400 MHz. The analysis of the spectra shows that the mean value of the spectral index for galaxies in an interval of declinations -2 to -13 deg is somewhat higher than for those with declinations from -2 to + 20 deg, while the mean spectral indices of quasars and unidentified sources for these two declination ranges coincide quite well.
