Keyer Notes

Schematics of the keying circuit I use for my Kenwood TS-50
If I use the right audio channel to key the radio the audio output needs to be around 85%
I would sergest reducing the value of the 1k resistor
also I have omited the LED tx indicator in my circuit
The audio transformers and opti coupler galvanicaly isolate the pc from the radio
and screened cable is recomended
