    Would it hurt to include a summary of the project and video in WORDS ?

    Great project Jim, thanks for sharing it with us.
    My only comment is why not add a display to show frequency ?
    A VFO project by Julio Cesar using the same parts as you has a small color LCD display.
    I built his circuit and it works well. Display would require SCK, SDA, +5v and ground connections and a few extra lines of code.

    What about using Pin Diodes for QSK and adding a button for 1Mhz jumps for band jumps.

    Agreed. A nice, concise couple of paragraphs is much more likely to be read by someone unfamiliar with the project than watching a 30 minute video.

    A class AB final using BS170 mosfets will give 1W+ with 5 components at a cost of $1.

    Neat project. I’d substitute the parts on your low pass filter with SMD and consider using an optocoupler rather than a mechanical relay—it’s QRPp.
    You may want to turn to the schematics of HackRF for further inspiration.

    I would pursue Analog Devices MAX4567 or something similar. Regardless of which direction you take this project, you're brilliant. You've really given meaning to software defined radio.

    Agreed 100% on a summary with words. I'm not so much into videos, and had MUCH rather read an article, or at least a short summary.
