Paul:
What you suggest, using a separate ground rod connected only to your
antenna tuner, is both unsafe and a violation of the National
Electrical Code.
Section 250.50 of the 2005 Code (on page 70-101) states: All grounding
electrodes (read ground rods) that are present at each building or
Hey Guys,
Having just finished my first K2 (#5945) I'm looking for
best-practices on grounding it properly in the shack.
This is going to be used at home, rarely, if ever, portable.
At first, I'm going to use a 12V battery to power it, and will get a
Samlex PS in the near future for when I do
The KPA100 has a ground lug.

My K2 (#337, QRP only) has a ground post. I may have come with one of the
options - not sure.

Your K2 must have the KAT-2, and the ground lug is attached to that.

Jeff,
If you are using a tuner in your antenna line, ground that instead of the K2

Grounding the case of ham equipment can be for one of 2 reasons - first
concern is an AC safety ground, but that is not required with DC powered
equipment, that
Thanks Don, and everyone who replied.
I don't plan to use a KAT2, and I like Don's explaination. Much appreciated.

Does the K2 have a circuit or PCB (main board) layer,
or signal that one could call a ground plane? Or does
a common ground plane or layer or signal - connect
from board to board? So that if one grounded his rig,
to an actual earth ground rod - all of these K2
circuits would be commoned to that.

Fred,
There should be no mental connection between an earth ground and a signal
return path - they are different things altogether. They may be connected
together at some point, but that is usualy best accomplished at a single
point lest circulating currents (and the resulting elusive ground

It sounds like what is being said is not to ground the chassis of
various rigs. That is, all modern rigs, power supplies, Home wiring
already have a common three prong plug and that should put everything
to a common ground just by plugging it in. This excludes such
historical anomalies like
Paul and all,
There is a big difference between 'not required' and 'should not be done' -
I trust I did not say it should not be done.
It is OK to ground the K2 - I wanted only to point out that it is not
necessary under the conditions stated. If the tuner is grounded and
connected to the K2 by
I have quite a few power supplies and I think they are all isolated from
ground, ie the metal enclosure is safety grounded to the house mains supply
(because they are Class 1 equipment in which the grounded chassis provides
the main barrier to shock hazard), but both low voltage output
Hi all
My K2 s/n 5361 is coming together nicely, up to now I've encountered no
problems whatsoever.
I just installed the receiver filter Xtals X7 through X11 and now I've arrived
at the point where these Xtals have to be grounded (page 53, last step).
The manual states that a special grounding

Glenn,
Tilt the board at about a 45 degree angle so gravity will help solder flow,
and more importantly, so you can see what you are doing. Use a large flat
area of your soldering tip on the side of the crystals to provide a better
heat path and heat until the crystal case itself melts the
I prefer to pre-tin the crystal cans before installing the crystals. That
way I can concentrate on doing one thing at a time. Like Don, I use about an
800F iron with a flat tip. Once there's a thin area of solder on the can
where I'll want to put the ground wire, it's much easier and faster to
Hi Glenn,
I was at the same point 2 days ago. It was really not a big deal to
solder this crystals. I made a couple of pictures that you can find here :
