Abstract: We present the results of spectroscopy of 71 objects with steep andultra-steep spectra $\alpha<-0.9$, $S\propto u^\alpha$ from the -Big Trio-RATAN-600-VLA-BTA project, performed with the -Scorpio- spectrograph on the6-m telescope of the Special Astrophysical Observatory Russian Academy ofSciences. Redshifts were determined for these objects. We also present severalother parameters of the sources, such as their R-magnitudes, maximum radiosizes in seconds of arc, flux densities at 500, 1425, and 3940 MHz, radioluminosities at 500 and 3940 MHz, and morphology. Of the total number of radiogalaxies studied, four have redshifts 1
