Abstract
Emission spectra of 11 extragalactic radio sources in a quiescent stat e and during bursts are analyzed in the frequency range 4.5 - 380 GHz. Quiescent spectra are explained by synchrotron radiation of a complet ely developed jet in a radial magnetic field of an active-nucleus sour ce (hedgehog model), whereas the spectra of bursts are accounted for b y the emission from new components in a jet ejected from the nucleus.
