[Elecraft] Connecting XLR 1/4 Inch Mic Cable to K3S

[Joe Subich, W4TV]

The standard XLR (3 pin) mic wiring is Mic+ to pin 2,
mic- to pin 3.  Simply connect pin 2 to the tip of a
3.5mm plug and connect pin 3 to the sleeve of the 3.5mm
plug.  Leave pin 1 (shield) float on the rig end (or
connect it to the chassis/ground lug - the sleeve of
the 3.5mm jack is not grounded!).

To connect an XLR (3 pin) mic to a Foster (8 pin) jack,
connect XLR pin 2 (Mic+) to pin 1 of the Foster,
connect XLR pin 3 (Mic-) to pin 7 of the Foster,
connect XLR pin 1 (Shield) to the *SHELL* of the Foster
plug (should be connected to chassis/case).
