The BATSE earth-occultation database provides nine years of coverage for 76 sources of gamma-ray emission in the energy range 35-1000 keV. For transient sources, this long time-base dataset makes it possible to study the repeated outbursts from individual objects. We have used the JPL data analysis package EBOP (Enhanced BATSE Occultation Package) to derive the light curves and the time evolution of the spectra for the microquasar candidate sources GRO J1655-40 and GRS 1915+105. We present comparisons between the spectra of these objects and the microquasar candidates Cygnus X-1, GRO J0422+32, and GRO J1719-24, and discuss the resulting constraints on models of the gamma-ray outbursts.
