  We discuss the results of the radio studies of the X-ray binaries with
relativistic jets. We carried out a multi-frequency (1-30 GHz) daily monitoring
of the radio flux variability of the microquasars SS433, GRS1915+105, and Cyg
X-3 with the RATAN-600 radio telescope during the recent sets from 1 November
2006 to 31 August 2008. From December 2005 radio emission of Cyg X-3 after four
years relatively quiescent levels (100-200 mJy) dropped down to $\sim$20 mJy,
and then we detected a lot of bright radio flaring events (1-20 Jy) followed
the very variable (from 0 to 0.5 crabs) 15-50 keV X-ray emission, which was
monitored in the Swift/BAT ASM program. Again from December 2007 to March 2008
we have daily measured almost quiescent fluxes from Cyg X-3 but in April 2008 a
bright radio flare with clear synchrotron self-absorption was detected. We
detected several bright short-term flares from GRS 1915+105 which could be
associated with active soft X-ray events. In intense measurements of SS433
fluxes (often mutually with X-ray and optical observations) we detected massive
ejections during powerful flares. We discuss the various spectral and temporal
characteristics of the light curves from the microquasars. Monitoring of the
flaring radio emission is a good tracer of jet activity X-ray binaries.
