Re: uBITX How to wire key jack for paddles?


Hi Kevin

This is the circuit from for straight key and iambic key.

I have avoided the straight key jack by wiring a stereo plug with the straight key wire connected to the DIT contact. (In my case it is the ring as I have a left handed iambic key). I am using Ian's 1.08 firmware version which allows you to select straight key or iambic key. Just plug in the appropriate key and away you go.

Hi Ashar,
in your previous message on this post you said, "from the key jack, a 2.2K to the dot padde, a 10K to the dash paddle"
where do they go on the other side of each resistor..Perhaps you could make a schematic ?
