Interplanetary-scintillation observations of the radio sources 3C 43, 3C 48, 3C 49, CTA 21, 3C 119, 3C 138, 3C 286, 3C 287, OQ 172, 3C 309.1, 3C 343, and CTA 102 have been carried out at 102 MHz. Scintillations were observed for all sources. Estimates of the integrated flux densities and the flux densities of the compact (scintillating) components are presented. The spectra of the scintillating components have cut-offs at frequencies below 1 GHz. The physical conditions in the cores of the quasars and radio galaxies studied are estimated. In most cases, the energy of relativistic particles exceeds the energy of the magnetic field, sometimes by many orders of magnitude.
