The correct connections for an XLR (balanced) connection on
a dynamic mic to the Elecraft/Kenwood 8 pin Foster plug are:

   Mic     Foster
    1       SHELL   Shield (Ground)
    2         1     Mic Hot
    3         7     Mic Return


The correct connections for an XLR (balanced) connection on
a dynamic mic to the Elecraft 3.5 mm (rear mic) jack are:

   Mic     3.5 mm
    1        N/C    Shield (Ground)
    2        Tip    Mic Hot
    3       Sleeve  Mic Return

One should use *twisted pair* wiring for audio - particularly in
conjunction with the rear mic jack since there is no opportunity
for a grounded shield.
