  The principal results of daily observations with the RATAN-600 radio
telescope of X-ray binary with relativistic jets microquasar SS433 in
1986--2003 are presented. We have measured the flux densities at 0.96, 2.3,
3.9, 7.7, 11.2 and 21.7 GHz in different sets, duration from a week to some
months. In general there are 940 observations of SS433 and more than 4500 flux
density measurements in the period. Observations show that radio spectra are
well fitting by a power law. The mean spectral index remained the same,
$-0.60\pm0.14$ during almost 20 years at least, and mean accuracy of the index
determination was better than 0.1 in our multi-frequency observations, i.e. it
was higher than in the intensive two-frequency monitoring of SS433 with the
three-element GBI interferometer. Flux density data and spectra `on-line'
plotting are accessible on the CATS data base site: http://cats.sao.ru/.
