Freesound Forums

Hi all, I am quite new to freesound... I am looking for old radio transmissions and hsitorical samples about russian soviet history (i.e. loudspeakers transmitting info and propoaganda during Stalin's time)... does anyone know how to help me? Are there any accessible sound archive i can look for?
thanks a lot
