In the present paper the farther investigation of a galaxies cluster listed in our catalog ( Serrano et al. , 1996) is suggested. The optical identification of radio sources , observed at 1400 MHz (Perley, Broderick, 1996) is made. More than 10% of objects of our catalog show radio emission. 70% of them are active galaxies characterized by excess of brightness on blue print, and 50% of them are IR galaxies ( Fullmer et al., 1989). In agreement with the statistical results of Condon ( Condon et al., 1991),it is shown that the main part of IR galaxies is a faint radio objects and only small part of them is powerful radio sources identified with Seyfert galaxies. Almost of them have compact core and a structure like spirals in optic. We find that the radio emission is detected from the central part of galaxies. These galaxies are of particular astrophysical interest because they possibly have the jet-structures on small scales ( parsec ).
