Re:[求助]问:高频磁环能绕制矿石机的线圈吗?
按5楼的地址,我去看了,下面是作者的开场白:
This is not intended as a "How To" article for a beginner. The following is supplied as information only. Some of the techniques used in the construction of this radio are very advanced and not recommended for a beginner or even an intermediate builder.
这不是向初学者介绍怎样来制作(矿石机)的文章,
只是作为资料提供给大家。本制作中有些地方使用了
非常先进的技术,不适合初学者和中级制作水平的人
制作。(翻译得不一定精确,大概意思如此)
我觉得就是做起来困难些,先进的技术倒看不出来。
那个输出变压器,还有那些银片的空气可变电容和波
段开关比较高级,一般人比较难搞到。
这个矿石机共用了5个线圈,天线(调谐)线圈不是磁
环的,是空心花蓝式的。后三个线圈是磁环的。
L1,L2,调谐线圈(空心花蓝)
L3,陷波线圈
L4,偶合线圈
L5,检波线圈<img src="attachments/94kk/20064161939892.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
