We present examples of radial velocity measurements obtained with the Poznan Spectroscopic Telescope (PST). Observations on PST are run on regular basis since August 2007. The PST is a binary telescope with two 40 cm mirrors of a Newtonian focus, connected by optic fibers with an echelle spectrograph. Radial velocity measurements are done for δ Sct, β Cep, classical Cepheids, eclipsing binaries and other types of variable stars. Echelle spectra reduction and radial velocity measurements are performed with IRAF package. Final results are obtained from cross-correlating stellar spectra either with radial velocity standards or the program star itself using IRAF fxcor procedure.
