[Elecraft] Microphone Qusestion

[Bob McGraw - K4TAX]

Thanks Jim.

I have provision for that if and as needed.  That is one reason I use a 
3 wire shielded cable where many installations only use a 2 wire 
shielded cable.  Someone reported that both pin #7 and pin #8 go to a PC 
board ground.   Grrrrrr

I know my other radios have a dedicated pin as mike ground and another 
dedicated as chassis ground.  This is connected by a very short jumper, 
about 3/4",  from the connector to the chassis.

Once I get the radio  I may investigate connecting pin #8 direct to chassis.
