[Elecraft] Jumpers for the K2 mic?

[Don Wilhelm]

Frank,

The K2 microphone configuration header is on the back of the Front Panel 
Board.  See the KSB2 manual for details on the wiring for that header.

If the prior owner did not tell you what the microphone configuration 
header is wired for, you will have to do a physical examination of the 
header wiring compared to the wiring information presented in th KSB2 
manual.

To get to view the microphone configuration header, you must remove the 
Front Panel from the K2.  That means first removing the top cover (or 
KPA100), and then removing the KAF2 or KDSP2 options (if present) from 
the Control Board.  There will be either a standoff or a 4-40 screw 
securing the Control Board to the standoffs behind the front panel.

Once those connections between the Control board and the Front Panel 
board are removed, the Front Panel can be freed by removing the 4 screws 
holding the FPB to the K2 side panels and pulling the FPB forward.

Trace the wiring on the Microphone Configuration Header to determine if 
your particular microphone is wired correctly (see the KSB2 manual).

That should allow you to set your K2 to the microphone which you are 
trying to use with the K2,

73,
