29 radio sources identified with CGCG galaxies brighter than mp = 15.7 were detected during a survey of the Perseus and Coma superclusters; 9 of these radio galaxies were not previously detected. The survey, carried out with the Bologna Northern Cross Radiotelescope, covers large regions around the two superclusters with a limiting sensitivity of S408 = 0.07 Jy. Flux densities at several frequencies were found in the literature for 19 of the cluster galaxies allowing the determination of their average spectral index. Contour maps of the sources with interesting radio structure are presented.
