[Elecraft] Electret microphone wiring

[Ramiro Aceves]

Hi all,

I am trying to use a cheap computer microphone in my K3, front 8 pin 
connector. I have some doubts that I would like to solve before making a 
mistake:

1- Can I use pin 1 directly atached to the electret capsule and set bias 
in config:MIC SEL? Or should I use also some kind of resistor/condenser 
arrangement to the 8V DC pin6?
2- For GND: shoul I use pin 7, pin 8 or both pins?

Thank you very much in advance.

Ramiro.
