    Your audio path is good. We need to disable anything that is distorting the signal and making it unable to be processed.

    Check the following things:
    -AGC: OFF or Fast
    -Filters: Wide or open
    -IF Shift/Pass Band Tuning, PBT: Centered and Wide/Open
    -Noise Blanker/NB: OFF
    -DSP: OFF
    -PREAMP: OFF


    I'm not familiar with Yaesu HF rigs. Check for correct MODE selection:
    -USB is normally used for all digital modes except RTTY which is LSB
    -Is there a "USB-Digital" selection like recent Icoms have?

    Are you overdriving the program processor, or getting distortion at a single stage of the audio chain?
    -Check each stage beginning with the radio Audio Output for setting. Begin with controls at the center or mid-level position. If the overall level is extremely high or low, go back through the stages and increase or lower making the levels consistent.
    -Avoid having any particular stage being at an extreme of High or Low which might cause distortion!

    Once you start decoding properly you can start making adjustments to improve reception, particularly the use of Filters to narrrow the passband around a desired part of the band or particular signal.

    Just for grins, have you connected wsjt-x directly to the radio and bypassed ham radio deluxe as the controller?

    every once in a while I will see the decode turn blue for a second or so
