  We summarize the results of VLBA and global VLBI observations of SS433
between 1995 and 2000. With these observations we resolve the inner jet of the
source and identify an absorption region (~25 AU), the "central radio gap". The
radio gap is caused by free-free absorption of the jet radio emission by a
flattened outflow from the binary system. Radio emission is detected on 100 AU
scales perpendicular to the normal jets ("equatorial emission region";
"equatorial outflow"). At some epochs the emission is smooth but compact
features are frequently detected. We suggest that equatorial outflows may be
common in microquasars.
