That's may be the case if one is using an Elecraft microphone 
(or a computer headset in the rear panel).  However, if one 
has a Heil or Kenwood electret wired to Kenwood's specification 
it will not work.  The Heil/Kenwood will have a capacitor in 
series with pin 1 (Mic +) and a resistor to pin 5 (bias).  The 
cap will block the Elecraft bias on pin 1 and fail to connect 
to +5/+8 on pin 6.
