Completely agree! Soldering is effective, cheap and reliable if done
right - as is crimping, bar the cost of the tool.

FWIW, rather than invest in crimpers and practice as needed to get great
crimps, I simply solder the wires into the terminals as recommended by Wayne.
I place the terminals over the bare ends and solder, filling the part you might
crimp with solder. It's useful to align the terminals correctly so they slide
right into the PP housing when done. Also, be sure you do not get solder on the
terminal contacts. Some builders like to hold the wires vertically with a vice
to prevent soldering from flowing onto the contact area.
I've had no problems over the past 12 years or so using the PP connectors --
all but a very few are soldered.

Subject: Re: [Elecraft] K3 and Power Poles
On the topic of Power Pole connectors, I have a crimper that if I remember
correctly I bought from West Mountain Radio. It looks pretty similar to the
one sold by Powerwerx. I have had very little success crimping the #10 zip
cord sold by Powerwerx. Am I missing something? I have used these off and on
for a few years to crimp smaller gauge wire.
With the 10 wire the crimp looks terrible, and it is very hard to extract the
pin from the crimper without destroying the pin. If you do manage to get the
pin out of the crimpers it is almost impossible to push into the housing. Is
there something wrong with Powerwerx's zip cord? my crimpers? Is there better
cable to use, ideally something really flexible? A lot of my operation is
portable so this stuff is always getting plugged, unplugged, coiled, uncoiled,
etc.

I like Power Poles because they are serviceable, configurable, and
becoming more common/standard as time passes.
Would I prefer a CPC or other connector? Perhaps, but the Power Pole
does the job and at a manufacturing price point that makes sense.
If you do your cabling and cable routing correctly, you should never
have a problem. The connectors are rated to carry enough power to
satisfy the K3s' needs AT FULL POWER.
And there are ways/devices to make PP connections "more secure".

The Power Pole connectors on the back of my K3 provide for only a marginal,
non-secure connection to the cable coming from the power supply. Has anybody
out there “invented” or “discovered” a more secure and strong connection than
the one provided by the Power Poles? It is so easy for the connection to come
loose that makes me wonder how can they safely conduct the 20 amps needed for
the radio to operate at full power. I believe in strong and tight connections
when relatively high current is expected. Anybody out there with suggestions? I
would appreciate knowing from you. Thank you all.
