    Twin "airplane" main and bandspread dial with "R"-meter between them, antenna trimmer.
    Variant: RME-9D Spacial, extended coverage 1.45 - 32 MHz.

    First commercially produced communications receiver to offer a calibrated dial with bandswitching, bandspread, RF amplifier, R-meter, crystal filter and AVC in one package.

    Completely hand built from start to finish by a single assembler belonging to a team of several assemblers. An assembler would draw a complete set of parts and would be responsible for the mechanical assembly and the complete electrical assembly. Because competition was fierce for recognition on who was the best, each assembler would proudly sign his name under the chassis of each successful receiver as it passed inspection and final adjustments.

    Total number of RME-9D receivers built is probably around 500
