    I have recently acquired a pair of Kenwood Twins, R-599 and T-599,
    I now have them working very well, however I cannot find the 16 pin connecting lead
    which would help with tranceive facility.
    Any one with any ideas.? Roger G3XXR tnx.

    They are a nice looking set of twins that work very well.

    Unfortunately, the proper connectors are drying up. As I mentioned in one of the referenced posts, if operating them as originally intended as a transceiver, it may require installing a DB25 connector in place of the originals.

    The Kenwood Twins (R-599 / T-599) used the Japanese 16-Pin Hirose Electric (HRS),
    Minicon 1300 series Rectangular Connectors. P-1316
    The Hirose Minicon 1300 series uses ROUND pins (Kenwood Twins),
    a related series, the Sumicon 1600 series, uses FLAT pins (NOT suitable for Kenwood).
    ---
    The original Hirose Electric, Co. (Japan) 16-pin rectangular plug (1300 series, 1962)
    used on the Kenwood Twins cable (for transceive option/interfacing) are a bit rare.
    When the Hirose 1300 series was "in production", the retail price was ~ $25.00 each.

    Original Kenwood part number: KE30-9981-00
    Pacific Parts last stocked (2003) this part for $78 each.

    Digi-Key has the Hirose 1300 series data sheet (and cross reference)
    This datasheet has cross-reference numbers to NTT specification numbers (other suppliers)

    Mouser and Digi-Key are Hirose Electric distributors in the United States.

    Hirose rectangular connector series were very popular in Japanese video electronics
    (professional VCRs, video monitors) from late 1960s to early 1980s.
    Some amateurs have been able to acquire used connectors,
    from surplus Japanese professional video equipment (Panasonic, Sony) of that era.
