      I am looking for a stand-alone device I can connect a paddle/bug to practice sending CW. It would be nice if it can send dits (speed adjustable) and dahs (also speed adjustable, and work as well with a straight key.

      I recently purchased an out of date kit made my Ramsey Electronics that was suppose to do all that, but it didn't work when I finished it.

      I know I could use my radio but I wanted to save wear and tear on it.

      I also just purchased an MX T-Tone CPO kit, but looking on YouTube I don't think it's going to do exactly what I was thinking.

      Any ideas out there? Kits? Or even do-able schematics?

      I've been Googling it now for a while. I see a few item, but a lack of operational descriptions!

      Thanks

      Try fixing the Ramsey kit, they are very helpful with troubleshooting. A CPO is a Code Practice Oscillator. It makes a tone when the input is shorted together

        A CPO is a Code Practice Oscillator.  It makes a tone when the input is shorted together as if you use a switch or telegraph key.  Sometimes the have adjustable tone.  Most have a volume control.  It does nothing more

        An electronic keyer is a circuit that goes between a single or double pole switch with a double throw and center off, or telegraph key type called in USA a paddle and in Europe a manipulator.  The electronic keyer usually has a sidetone which is similar to the CPO and usually has tone and volume adjustments.  A keyer generates dots and dashes with electronics and the speed is variable.  Some keyers have more features including an input for hand key or bug.

        Bugs generate dots by a pendulum, dashes by hand.
