[Elecraft] RFI in audio chain

[Bob McGraw - K4TAX]

Oh but it is.  There is pin #1, pin #2 and pin #3 plus a ground 
terminal.  The cable between the mike and radio should be 3 conductor 
shielded.  Thus  - Red, Black, White and shield.  And the shield should 
be connected at one end only, preferably the signal receiving end or 
mike connector at the radio.  That way, there is no current flowing on 
the shield.
