    Very nice! Did you design the DDS VFO? Do you have Gerbers/DXFs that you are willing to share?

    How does it play?

    I noticed a CW key plugged into your BitX. Do you inject an audio oscillator signal into the BFO mixer or send an offset VFO signal directly to the TX buffer?

    Congrats on your great Homebrew!!! I just looked at a BITx20 at the Visalia DX Convention, but they wanted nearly $200 for it, so I went home without it. Sure would have been fun to build and modify though! Enjoy your beautiful radio!
