Callers have a few minutes to describe themselves.
Mr. Kaplan often tells listeners. ''Say something. Most callers are Russian, but some are not. There are lots of bars with pretty women,'' he said. In fact, he is in a small, hot, cluttered studio, wearing headphones and fidgeting with a pen, taking 40 to 50 calls an hour. A few feet away, Dmitry Istratov handles the phones, controls the sound levels and plays the music, mostly Russian and American pop.
