K2 Microphone Jack Grounding

VK1OO, Mike Walkington
Hi,

Just wondering what the definitive advice is on doing the K2 Microphone Jack
Grounding modification. I note there is no mention of doing this in either
the K2 or KSB2 manuals?

Mike - Details of this are at
http://www.elecraft.com/Apps/k2_microphone_jack_grounding.htm

I carried out this mod on my K2 as a matter of course. I felt that it
only was right that the 8-pin microphone connector should be earthed. I
have to say that I am surprised that this mod, dated 17 November 1999,
has not yet found its way into the K2 assembly instructions.

Mike,

Do it - it certainly will harm nothing even if it does not cure any problem.
It can be done without disassembling the front panel - remove the left
side panel, scrape a bit of the solder mask off the ground plane next to
the microphone jack and solder an 'L' shaped wire to both the mic jack
and the ground plane.  It takes a lot of heat (and more time than a
normal connection) to make the solder flow, so use a higher temperature
on your soldering station or pull out the 'big gun' for this task
