Install the KSB2 option or Rework Eliminator™ KSB2 Parts

kit supplied Front Panel components

on the front/top of the board

near the cutout for the headphone jack.

C4 – C8

(.01 μF)

Q3 (2N3906)

RP3 (10K, 8 pins)

R13 (68.1K, 1%)

[ ]

Install P1 (the Microphone Configuration Connector) on the

back/bottom of the board. Insert the shorter pins (tails) into the

board.

After soldering one pin, ensure P1 is mounted flush.

Take your time soldering the remaining pins of P1, being careful to

avoid touching and damaging nearby switch S6 with your iron.

[ ]

If you have the Rework Eliminator™ Internal Mic Adaptor

(IMA), skip ahead to page 72 and

insert a new step to assemble

and install the IMA prior to plugging in the Control board.

Otherwise,

review pages 17 and 18 in the Elecraft

KSB2 manual,

and

configure FP-P1 for your microphone. (Do this now!)

(Now go back and resume assembly at the bottom of page 23.)

(after FP PCB assembly is completed)

Once these components are installed, you may wish to check off all

of the steps under the Front Panel Board Components section on the

bottom half of page 16 in the Elecraft

KSB2 manual. If you haven’t

yet purchased the KSB2 option, you can download the manual from

Elecraft’s website, then print out page 16 and keep it with your K2

manual for future reference.

For C4 through C8, do not use any other .01 μF caps that belong

to the base K2. Instead, be sure use the special 5mm (0.200") lead

spacing caps that came with either the Elecraft

KSB2 option, or the

Rework Eliminator™ KSB2 Parts kit.
