    Jim -

    Questions about wiring up the Astatic D-104 microphone to a radio is a Top 10 FAQ.
    It is just a matter of referencing the G4WPW web site (web page link below) OR
    reading the schematics and manuals for these products and "connecting the dots" (web links below).

    NOTE: Modern amateur radio equipment usually has no need for micorphone pre-amps of this era.
    These pre-amps were largely installed for the <$100 CB radios of the 1970s and address Astatic's Hi-Z crystal element output
    to match to modern sold-state Lo-Z radio microphone inputs.

    KEEP gain knob (D-104 pre-amp) at MINIMUM setting to avoid distortion or spatter.
    Adjust the mic gain control on your FT-101E for proper audio.

    G4WPW has compiled Microphone Connections to answer 99% of these microphone wiring questions

    Every need to "open up" that Yaesu FT-101E for repairs? -- then you need the Service Manual

    All the links he posted for you above are down-loadable and you can print them all out as I did. I have 2 complete lines of Yaesu Ft-101E's and a set of twins FL-101,FR-101 loaded with every option. Carol's site is a wealth of information for all Yaesu radios and even the QTR-24 clock that helped me also.
