You are hearing an amateur radio repeater. Very simply, a repeater consists of some electronics equipment which boosts radio communications range. A repeater has a receiver and a transmitter operating on different frequencies. They utilize antennas located as high up as possible. Because ot the high location and very good quality equipment, repeaters can receive transmissions from much fur ther away than can be normally done and can be heard at a further distance than is commonplace. The...

With the recent mutual recognition between the U.S. and China, the feeling among many DXers is that BY stations will soon be blossoming everywhere. Although the chances for a true-blue BY-type operation from downtown Peking are better than they have been in many years, those with inside knowledge believe it may still be a bit premature to expect any immediate action, especially by any visiting U.S. operators. The operation, when it comes, will most likeiy develop along the lines of the Iraq...
