As kalinka mentioned, people learning Russian at even the earliest levels can benefit for listening to the radio (or just about any dialog). Be aware though that you don't instantly start learning and until you know a few thousand words, you can't understand more than a few words and sentences from time to time, but you do get words stuck in your head that way which makes them easier to remember when you translate them. There are other benefits to listening I just want to stress that you won't have amazingly fast progress.
