业余无线电爱好者是一个小众爱好群体，他们彼此之间以呼号相称，跨越干里的几分对话只为联通成功刹那的惊喜。
远到国际空间站、奥运会电台，近到灾区救援，跨区通联。
在窄窄的波段上，交错着不同国家试探的信号，宛如婴儿诞生时的第一声啼哭，渺小而伟大。
Amateur radio enthusiasts are a niche hobby community,
they call each other by their call signs, and a few moments of conversation across thousands of miles just for the surprise of a successful moment of connectivity.From as far away as the International Space Station, the Olympic Games radio, to as close as disaster relief, cross-regional communication.
In the narrow waveband, the signals from different countries are interlaced, just like the first cry of a baby, so tiny but great.
