  We present results of long-term daily monitoring of a sample of Galactic
radio-emitting X-ray binaries showing relativistic jets (RJXRB): SS433, Cyg
X-3, and GRS 1915+105, with the RATAN-600 radio telescope in the 0.6-22 GHz
range. We carried out the modeling calculations to understand the temporal
(1--100 days) and spectral (1-22 GHz) dependence. We tested the finite jet
segment models and we found that the geometry of the conical hollow jets is
responsible for either a power law or an exponential decay of the flares. SS433
was monitored for 100 days in 1997 and 120 days in 1999. From the quiescent
radio light curves, we obtained clear evidence of a 6.04-day 10-15% modulation.
Three powerful flares (up to 13 Jy) from Cyg X-3 were detected in April 2000.
