大多数袖珍式计算机辐射出一定大小的无线电频率,正规的晶体管收音机很容易接收到这些频率。不同品种的计算机在整个高频段(3～30兆赫)内辐射出强度不等的各种信号,有些计算机辐射出来的频率一直高至商用调频波段(88～108兆赫)和电视13频道(216兆赫)。
Most pocket computers radiate a certain amount of radio frequency, and regular transistor radios easily receive these frequencies. Different types of computers radiate signals of varying intensities over the entire high frequency band (3-30 MHz), with some computers radiating frequencies up to commercial FM bands (88-108 MHz) and TV 13 (216 MHz ).
