[Elecraft] Static discharge
Christmas Day 1967. Snow falling heavily. I had a 2 element Cubical Quad at 50 feet. Separate feed lines for 3 bands. I heard a loud CRACK. I kept occurring. Like an ignorant operator I had not grounded the unused feed lines. I finally realized that the coax was arcing at the PL 259. I grabbed it with my hands. I won’t do that again. Fifty + years ago I was still learning. I continue to learn from my mistakes 73 Jim W9VNE/VA3VNE Sent from my iPhone __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Static Discharge Through K-Pod
There has been very low humidity this week, and I have had some shocks at home. When we got lots of static discharge shocks after walking on my mother-in-law's carpet, I put some 1 Meg Ohm resistors under the light switch cover screw for her to touch in the winter before the switch. Silly idea but it worked to discharge all the static but so slowly as to not experience the shock. There might be a similar solution to touching the K-Pod. My K-Pod arrived today, and my only annoyance is that the cables are too short for both the radio line and the 12v line.

Warning! Until that dries, it could be very slippery!

Chuck,
I had this problem in my carpeted shack with a desk chair rolling around
on a vinyl chair pad. After a little testing I determined that the metal
case of the K-Pod is not grounded.
The KPod uses a straight-through 6 conductor cable with identical RJ
connectors on each end. I built a slightly longer cable for my KPod,
using 6 conductors of a stranded 8 conductor flat ethernet wire. A 7th
conductor provides chassis ground from the K3 to the metal case of the
KPod.
I have had zero issues since grounding the K-Pod case.

Greetings, All!
I'm getting static electricity shocks through my K-Pod case, and I need
some suggestions for mitigation.
Background: I keep my K-Pod on my operating desk just to the right of
the
shack computer mouse. I've noticed when I walk over to the desk and
grab
the mouse, the K-Pod will beep. Further investigation shows I'm
getting
static electricity discharge from my finger through the K-Pod, this
morning
I even noticed an arc from my pinky finger to the K-Pod case. When the
K-Pod beeps, the D1 and D2 lights will cycle.
The shack is carpeted, and I have a rolling chair on one of those
plastic
chair mats (which can probably go away if necessary,) I suspect that
mat is
probably contributing to the static problem.
Obviously, I don't want static electricity discharging through my K-Pod
and
then through my K3. I'd welcome any ideas for static mitigation
strategies. I was thinking some sort of grounded mouse/keyboard mat,
which
used to be more common, but seem hard to find these days.

Chuck,
I'm also in an area of low humidity and such static discharges
are a problem. I have everything grounded together and a small
patch of aluminum foil connected with a 1 megohn resistor. After
a trip across the carpet and before touching anything, I touch the
foil. The resistor prevents a spark but discharges the charge. That
may be worth a try for you.

Re: [Elecraft] Static Discharge Through K-Pod
The real issue here is the lack of household humidity. A humidifier is probably in the real fix. Several hours of a near-boiling pan of water on the kitchen stove would likely be enlightening. Or, get a "real' anti-static (desk size) work mat with wrist strap. I have one permanently atop my operating desk in front of my K2 and K3. Hint: Amazon is your friend. (:-) 73!
