使用400瓦天线加感线圈制作的矿石机实验

libopp

近日淘到一线圈材料为镀银2mm铜线脱胎绕制，38圈，Q值较高。双连为并连使用。矿石为自制：硫磺+铅。猫须为镀银弹簧。
收听效果：天线5M。地线接水管。耳机600欧军用舌簧。在成都市中区，可收到三个电台，中国之声、四川人民广播电台（声音响亮，中午在离耳机50公分外可清楚听到，可能带舌簧喇叭没问题，下一步准备自造一喇叭）。和夜间收听到一电台（信号差）用2200欧军用耳机实验灵敏度有提高，但差别不大，音质不好。矿石与2AP9相比，在调整猫须的接触点有些点位与2AP9差别不大。同时找了一些氧化的金属做实验基本上都能发音只是效果太差。<img src="attachments/94kk/200641314391192.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt='Click here to open new window

线圈非常漂亮！顶！！！

你这个线圈一般人可能难找呀。

山东老姜

这个可怜的加感线圈实在是屈材了

做得很好。检波器也是自己作的吗？楼主到什么地方找来这么多镀银的东西呀？

天缘

我很喜欢那检波器的样子！做得很好看！

我喜欢这张，2AP9的雄姿！

阿里巴巴

我想,用400W功放里边的滚桶电感和共轴的真空可变电容器组来做更好啊
