笔者购买了一台“日升宝”ECB-RS9703收音机,觉得该机使用十分方便;但是,它不能接收校园广播。以前看到不少关于将普通收音机改为校园广播接收机的文章,大体就是将可变电容并上一只小电容或者是在原来的谐振线圈上再串上几匝,其实这样多少有些不便。为此,笔者对ECB-RS9703收音机进行改装。打开机盖,找到可变电容旁边的电感L7,然后用小螺丝刀将其稍稍压紧。经过如此的 I bought a “Rising Sun” ECB-RS9703 radio, I feel very easy to use aircraft; However, it can not receive campus radio. Before I saw a lot about the ordinary radio to campus radio receiver article, the general is a variable capacitor and a small capacitor or a few turns in the original resonant coil string, in fact, somewhat inconvenient. To this end, I modify the ECB-RS9703 radio. Open the cover and find the inductor L7 next to the variable capacitor, then use a small screwdriver to compact it slightly. After that
