You can view my other homebrew radio on my qrz page good luck and hope you are able to resolve your issues and sorry i cant be more help kind regards Dave G0AYD.
Is anyone running a uBitx (with OEM version 5.1 firmware) on CW? I tried, but the initial element (dot or dash) is so badly truncated by the TR and mode-switching delays that it comes out as a shortened dot (or less). This was in hand-key mode, using an external keyer for actual code generation. The effect is lessened at very slow speeds because the overall length of all of the elements is greater, but seems to preclude operation at even moderate speeds.
It's pretty disappointing to have a QRP rig that doesn't do CW. Is there a work-around? Is CW operation possible with other firmware (KD8CEC)?
