Title of the communication: Multifrequency 1-22 GHz Spectra Monitoring of Blazars and Jets in 1995-1996
Preliminary abstract (12 lines max.): New results for measurements of a sample for about 170 objects, selected from the VLBI survey (Preston et al.,1985), are presented. Monitoring observations have been done at 31, 13, 7.6, 3.9, 2.7 and 1.4 cm for the each spectrum quasi simultaneously (with accuracy up to a minute) at the radio telescope RATAN-600 during up to 5 sets from August, 1995, to June, 1996, to study a spectra variability of blazars and other AGNs. A model analysis shows that the main deposit to the majority of obtained spectra of the sources may give the emission of compact jets on the milli-arcsecond scales.
