[bars] CW KEY

[KC1SOZ]

Hmm. Interesting piece of hardware and software but it's not what I have in
mind.

What i want to do is replace my CW key with a computer controlled
relay/switch that does what a physical CW key does. When the key is
pressed, it closes the circuit and the radio transmits and sends the CW
audio signal all on its own. No need for external audio connection from
anything. Don't all HF radios come with a 1/4" jack for a CW key? I want to
unplug the key and plug in my device, and control it from my PC. For RX
audio I already have an input to the PC with a $5 USB sound card.

I've searched everywhere and can't find anything like this. Maybe this will
be my next Arduino project. 🤣

73,
KC1SOZ
