  • Notes

  • *DX Switch for Distant FM Stations
    *Very Compact Mounts Anywhere

    Easily hooks up to your present AM car radio. Includes lighted dial, on-off pilot light.
    Convenient switch lets you choose between AM, DX for distant FM listening, and higher
    sensitivity or LO for local FM tuning. Mounting bracket. Solid state circuitry.                           12 VDC neg. grd. 

    The converter is connected in series with the car antenna and the car radio. When the FM listening is selected, the FM channel's audio output is used to AM modulate a fixed (quiet) frequency that the AM car radio is tuned to. Usually, the converter will have a tuning slug or similar device to adjust the broadcast frequency to a quiet spot.
