The spectral analysis of the RC-catalog of the experiment "Cold" containing 840 radiosources in the interval of right ascension 4-22h are made. 280 spectra of radiosources are presented; 215 spectra are new. The mean spectral index for 196 objects with steep spectra (alpha >= 0 5) and flux densities >12mJy is 0.87+/-0.01. The preliminary optical identification of radiosources with catalogued galaxies is done.
