Grounding mic connector body on K2 front panel board

W0YG, Charlie Summers
Somewhere I saw a recommended mod to ground the front panel mic connector
body.  I am unable to locate this now.  Can someone point me in the proper
direction?

Thanks and 73,

Charlie, W0YG..>>

Charlie,

The mod is not difficult - remove the front panel and separate the board
from the dress panel.  Then wrap a bare wire around the threads of the mic
connector, twist it tight, and run one end over to the ground loop on the
left end of the board - solder the wire to the mic connector body (requires
a LOT of heat - dwell with the iron until the connector body itself melts
the solder) and solder the other end to the ground loop.  Reassemble the
front panel - Done.

The original write-up by Wayne N6KR should be somewhere in the archives, I
believe back in 2000 or 2001.

73,

I just did the mod on my K2's in an effort to remove RFI from the audio. It is
much easier to just remove the left side panel. That gets you enough access
to the mic connector and the ground loop without the trouble of pulling the whole
front panel apart. I did not wrap the wire all the way around the connector, just
soldering it seemed secure enough.
