    That looks great! I may have to invest in one.

    Hi, I bought one, and modified it to work on 6m band. Some impedance matching devices were modified and/or added.
    Approx. 30-35W available with 1-5W input. The 80m LPF was replaced with 6m LPF and the band decoder LM9314#10 and #18 were connected to enable 6m LPF automatically by FT-817. Working great !

    Very powerful, you can put the schematic out, but also to optimize the circuit:)
