A new super-compact radio that needs no tuning to find the right communications frequency enables these computers to speak to each other.
通过一个不用调谐就能找到正确的通讯频率的新型超小无线电收发器，这些电脑可以互相通讯。
One reason this is hard is that radio telescopes must chop the spectrum into fine portions to study it, like tuning into a signal on a car radio.
研究工作进展困难的一个原因是，正如汽车收音机的调频一般，射电望远镜必须把光谱按照波段分成易于研究的片段。
