Q: PowerPole connectors

[Alexandr Kobranov]

Hello all,

having one question:

Are there delivered PowerPole connectors (to make power-cord locally)
with K3?
Or ready-made power cord?

Sorry if I missed such info, preparing "nest" for K3 and this is still
unclear to me...

Thanks for info,
73!
Lexa, ok1dst

The power cord and connectors come with the  kit.  All you have to do is
attach the connectors to the cord.  That,  by the way, is the only soldering you
will have to do when you build the  K3.

DonŒt complain. Nobody will understand. Or care. And certainly donŒt try
to fix the situation yourself. ItŒs dangerous. Leave it to a highly
untrained, unqualified, expendable professional.

Hi Lexa. The connectors and cable are included. You have to solder them on. So the K3 is not a no-solder kit. :)

To follow up what Ron said, what's important with crimping Anderson
connectors is to use a tool that doesn't just crush them. Many of the
Inexpensive crimpers just flatten the connector. You need one that has
a semicircular recess on one side and a "finger" on the other side that
pushes a dent into the back side of the connector while leaving it in

To expand on what Ron said, what's important with crimping Anderson
connectors is to use a tool that doesn't just crush them. Many of the
inexpensive crimpers just flatten the connector. You need one that has
a semicircular recess on one side and a "finger" on the other side that
pushes a dent into the back side of the connector while leaving it in
an overall round shape. If you distort the overall shape the connector
will not go into the shell. http://www.dcpwr.com/ has a good crimper,
and if, like me, you use PowerPoles all over the place it's good to
have one. You can solder after crimping if you like. I never solder
them without first crimping them.

Yes, I agree, I purchased the West Mountain Radio Deluxe one and very
pleased with it.
It meant shipping to the UK, but well worth it, if you are going to do a lot
of crimping - I converted ALL 12V leads that didn't have some form of
regulator (cigarette type) to PPs.

Just wanted to post a brief comment and recommendation that Elecraft improve the K3 power supply cable kit instructions.  

The instructions do NOT recommend soldering the connectors.  The instructions simply say "solder or crimp wires".  And there's also no warning against using the simple "crushing type" crimp tools, which render the pins incapable of proper insertion.  It just says to crimp in the center.

So the odds of folks screwing this up and getting very frustrated are fairly high without improving the instructions.
