Tuning In

When CNN's not on your hotel room TV overseas, a portable shortwave radio can keep you informed--if you know which nations broadcast in English and when. The Passport to World Band Radio has schedules for stations in 170 countries, plus a buyer's guide to top radio models. It's $19.95 from International Broadcasting, Box 300, Penn's Park, Pa. 18943.

    Before it's here, it's on the Bloomberg Terminal.
