We detect 353 radio sources from the NRAO VLA Sky Survey (NVSS) and the FIRST Survey within the areas of 179 Shakhbazian compact groups (ShCGs) of galaxies. Ninety-three of them are identified with galaxies in 74 ShCGs. Six radio sources have complex structure. The radio spectra of 22 sources are determined. Radio luminosities of galaxies in ShCGs are in general higher than those of galaxies in Hickson compact groups (HCGs). A comparison of radio (at 1.4 GHz) and FIR (at 60 μm) fluxes of ShCG galaxies with those of HCG galaxies shows that galaxies in ShCGs are relatively stronger emitters at radio wavelengths, while galaxies in HCGs have relatively stronger FIR emission. The reasons for such differences are discussed.
