要给一个不支持自动键的电台，diy一个转换电路板，可以吗？我猜用ne555这种芯片，让电键接触的两个触点分别产生点、划不同的脉冲就可以了，我不会电子，有没有大佬教一下怎么画这种电路图😋

另外多说一嘴，用简单的纯逻辑门ic搭出来的自动键并不好用，设置不了中断优先级，用起来手感很怪

闲鱼有成品吧，，找找看

我有现成的stc方案，有兴趣请联系我

k3ng自动键，开源设计，功能强大，甚至可以解码cw

@"Syryia"#p38393 确实，是我想的太简单了😁

How can I enable auto-key functionality on a radio that doesn't natively support it?

BG4ICR

Is it possible to create a conversion board for a radio that doesn't support automatic keying, using a DIY approach? I think using a NE555 chip could allow the two contacts of the switch to generate different pulses (dot and dash), but I don't have any electronics experience. Could someone please show me how to draw this circuit diagram?😋

On Xianyu, there are finished products available; take a look.

Syryia That's right, I was being too simplistic in my thinking.😁
