    Mythbuster Video #3 -- Using the VFO from a Yaesu FT-101

    FT-101 VFOI used LTSpice and Wes's FBA program (from LADPAC) to come up
    with a circuit that would provide the needed gain. I needed to get the 290
    mV rms signal (across a 50 0hm load) up to the 500 mV rms signal needed by
    the ADE1 mixer.  Above is the amplifier that I came up with.  The key here
    is to adjust R2 and R1 to get the required gain.
