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

[Bob McGraw K4TAX]

For years the pro audio industry has connected balanced mikes to 
unbalanced inputs with excellent results.  No adapters, transformers, 
matching units, or unique grounding schemes are required.  Just correct 
wiring as I described earlier.   It is just two connectors, one XLR for 
the mike and one 8 pin Foster connector for the radio and a length of 2 
conductor shielded mike cable.
