[Elecraft] Bonding KX3/PX3/KXPA100 - any examples?

[John]

Thanks for the picture of your FD setup

That first picture reflects one thing I hate about my KX3 and PX3 - when you have
everything hooked up, it is one mass of wires everywhere.
The KX3 and PX3 is a fantastic pair in every other way, but dang, I can’t handle
the crows nest that it creates. 

If there is ever a KX3 MKII, I think Wayne needs to look at cutting down on the number 
of separate cables going everywhere…and if possible tuck the connectors into the
back of the radio, not the sides….it just makes it far worse with the cables coming
out the sides.
One thing that could be done, is combine the 12v DC supply for the KX3 and PX3, 
so they don’t require their own  DC supply. And their could be a single wiring 
loom, and perhaps make use of a USB cable for connectivity.

...shows a strap of copper running behind all the gear shown roughly
following K9YC's advice.

I used some 1/4 inch braid I found somewhere, crimped some lugs on each
end and connected each chassis to the strap.

The RigBlaster connects via one of its case mounting screws.

The PX3 and KX3 connect via one of the chassis thumbscrews.

Not shown is a 5V linear regulator to power my USB splitter from a Pb
equiv. battery.  It uses the copper strap as the heatsink.  This works
quite well.

I've never encountered the noisy conditions that Jim's steps help
mitigate, but I think it is a good idea regardless.
