  In this paper, we attempt to find out the `spectro-temporal' characteristics
during the jet ejection, of several outbursting Galactic black hole sources
based on RXTE-PCA/HEXTE data in the energy band of 2 - 100 keV. We present
results of detailed analysis of these sources during the rising phase of their
outburst, whenever simultaneous or near-simultaneous X-ray and Radio
observations are `available'. We find that before the peak radio flare
(transient jet) a few of the sources (in addition to those reported earlier)
exhibit `local' softening within the soft intermediate state itself. Except the
duration, all the properties of the `local' softening (QPO not observed,
reduction in total rms, soft spectra) are observed to be similar to the
canonical soft state. We find similar `local' softening for the recent outburst
of V404 Cyg also based on SWIFT observations. Fast changes in the
`spectro-temporal' properties during the `local' softening implies that it may
not be occurring due to change in Keplerian accretion rate. We discuss these
results in the framework of the magnetized two component advective flow model.
