1.检修晶体管收音机时,若中波位置的中、高端(通常在1000kHz以上)收台时夹杂着短波电台信号,愈往高端,短波台愈显著,且不稳定,此现象多伴属天线回路有问题,确切地说不是磁棒天线初级断线就是一端接地不良。请初学者检修时留意。2.出差或旅游者大都喜欢带上一台袖珍式收音机,用它收听新闻、欣赏音乐,其实收音机远不止以上功能,我们利用收音机磁棒天线具有明显方向性可大致判断出某些大城市的方位。如在黄山,利用袖珍机很快判断出杭州、合肥、南京及上海等地的大致方向。
1 overhaul transistor radio, if the location of the wave in the high-end (usually above 1000kHz) to close the station with shortwave radio signal, the more high-end, shortwave Taiwan more significant and unstable, and many of this phenomenon is associated with the antenna loop There is a problem, specifically, not the primary bar antenna coil is poor grounding one end. Please beginners pay attention to overhaul. 2. Most business trips or tourists like to bring a pocket-sized radio, use it to listen to the news, enjoy the music, in fact, the radio is much more than the above functions, we use the radio magnetic antenna has a clear directionality can be broadly judged in some major cities position. As in Huangshan, using pocket machine quickly determine the general direction of Hangzhou, Hefei, Nanjing and Shanghai.
