hi all,

I want to build an external capacitive touch keyer for use with my bitx40. I know that there is built in capability, but i want an external unit.

Im looking at :


?
I think that's a good starting point but i was thinking of using a relay () and attiny85 dev board ( ).

Ultimately i my goal is to have a keyer that can be used with any radio. I'll strip out all code not needed and dont want the sidetone. Do i still need the transistor circuit? Cant i simply wire the paddles into the attiny85?Thoughts?
Suggestions?
