K3 power supply question

Franki ON5ZO
Hello group

Awaiting my K3, I am preparing the transistion from TS-850 and anticipate on
buying a compact SMPS.
I see that the power connection is an Anderson PowerPole receptacle. That
type of connector is not common here in EU or at least in Belgium.
Is there a mating male part supplied to fit the cable from the PSU? There is
a German (ham) distributor for these things but a crimp tool costs 66 Euro
(approx 100$) which is a silly investment to crimp only one connector.
Is there an alternative way of crimping or fitting the PowerPole?

Thanks for info / advice.

The K3 kit comes with a power cable and a pair of Anderson PowerPole
connectors.

You may crimp them (an appropriate tool is recommended) or they may be
soldered if you wish.

RE: K3 power supply question

Brett Howard
Whats the recommended tool for this.  I'm going to buy a tool once and
I'm willing to pay the funds for a good one but would like to know a
good reputable source to find the tool that will give a good price.  I'd
like the tool to be specifically (first use) for building my K3 so
that's the main goal.  Then I'm sure that some day I'll convert
everything to APP but right now I'm too busy do to pretty much anything
but work sleep and homework.

RE: K3 power supply question

Dick Dievendorff
I bought a PWRCrimp from West Mountain Radio, which cost about $50. It works
fine.  There may be others.

However I had already made the decision to use Anderson Power Pole
connectors for the various 12V equipment I have, and this was a decision I
made after using APP connectors for a while.  I soldered several of them
before I got the crimp tool and haven't felt it necessary to replace
existing soldered connectors.

If the K3 were my first device requiring APP connectors, I'd solder them.
If you decide later that you wish you had crimped it instead, you can then
buy or borrow the crimp tool and use up another pair of APP connectors and
cut a little bit off the cable and do it again.

This is one of those tools I don't use very much but I'm really glad I have
it.

If you choose to solder, I'd recommend using a minimal amount of solder and
try not to let it wick into the cable so much that there's no flexibility at
the end of the cable.

Hi Franki,

As of my knowledge therre is no european dealer fpr
Anderson PP. I order mine in the US and do not crimp them but solder
them.
In this way you can use them again if you have to and i do like
the solder more as crimping.
There is a lot of discussion whatever is
better: solder, crimping or both but solder is OK for me and I had never
any losses or trouble with it.

K3 power supply question

In reply to this post by Dick Dievendorff
Get the PwrCrimp from West Mountain Radio.  It is $50, but it will be the
only crimper you'll probably ever need for APPs.  I bought one three years
ago, and it has worked great for close to 200 APP crimps for me.

RE: K3 power supply question

In reply to this post by Brett Howard
What am I missing here? Why isn't Elecraft assembling the connectors
to the wire as a part of their process? Is there some reason to NOT
assemble them prior to shipment? We all know how a loose connector
can cause mysterious symptoms down the road.

I use powerpoles here, and I think I understand the system, but maybe not.

Some of Elecraft's customers are faced with having to spend $50 for a
tool to use only one time? Why?

In reply to this post by Jerry Flanders
They are probably not providing assembled for the same reason that they
don't provide it with the K2/100... it's a kit. It is NOT necessary to
buy the expensive crimping tool. There are instructions contained in
each KIT describing how the connectors can be assembled without using a
crimp. They can be soldered and if the directions are followed, it is
perfectly useful and reliable.

With the factory assembled K3, I believe that the APP connector is
attached to the power cable.

There was once an issue as to whether special tools were required to assemble a K3.  It was also described as requiring no soldering.  I believe the cable should be supplied ready assembled.  Don't forget those folks outside the US who pay a lot for US tools, plus shipping plus import tax plus mark up....

Most kit builders have a soldering iron, so they certainly don't have to crimp
the PP connectors.  

In your post you say, "Some of Elecraft's customers are faced with having to
spend $50 for a tool to use only one time? Why?", although they have a choice to
do it either way.  Why do you say that?  Elecraft does not require them to use a
crimp tool.

Please explain the logic of your statement.

K3 power supply question

Fern Rivard
In reply to this post by David Cutter
    For goodness sake, what's the big deal with the power pole connectors? Every ham should have a soldering iron and just use it. There's no need to use any kind of crimp tool for this. I've soldered mine and they work fine. I can't understand why there's been so much thread on something so basic so let's hope that's the end of it!

Re: RE: K3 power supply question

David and All,

Well, some folks want everything!  Maybe a voltmeter and an oscilloscope
should come with every kit as well!  Or perhaps a magnifying visor and
tweezers should be included when SMD parts are involved.

I'm being facetious--sorry!  But I think you are overreacting to the
problem.  You probably can make a decent connection without a special
tool--it's just harder to do.  You can take a non-specific crimping tool and
carefully manipulate the connector into a pretty good connection.  It's just
that the APP tool does it in one easy press.  Mitch at the Ham Stop (now
defunct I think) showed me how to do it at one of the hamfests.  He was
selling those $10 crimpers as well as the $50 APP crimpers, and demonstrated
why the APP tool was so much easier, but not absolutely necessary.  It took
3 or 4 different manipulating presses with the cheaper tool.  But the end
result looked pretty good.  You sort of have to coax (as in "persuade", not
RG8) the connector to form and clamp properly over the wire.  I think you
could do the same thing with most other crimping tools.  The problem most
people have with the cheaper crimpers is that they try to do it with one
crushing push.  That usually causes the connector to bend inwards too much
leaving a gap with wire strands not captured.  You want to clamp the
connector on, but without leaving a gap.  So, pushing both from the top and
from the sides helps you do this.  It doesn't take all that much time, but
it only takes a couple of seconds with the APP tool.

So don't assume you are SOL because you don't have the perfect tool.  I have
several connectors around that were made before I got the APP tool.  They
are just fine.  But now that I have adopted the APP system almost
exclusively, it only makes good sense to get the best tool.  Besides, most
of the really experienced folks I know say you get a better connection with
this system.  So why wouldn't you want to "bite the bullet" a bit and gear
up for a better system???

RE: K3 power supply question

In reply to this post by N5GE
I said that because I observed several guys on the reflector this
morning discussing buying the $50 tool. Apparently they never needed
it before, but felt that it is justified for the K3 assembly. Those
guys will probably never need it after the K3 assembly.

I will solder mine, but I remember reading years ago that crimp
connections are superior to solder - don't know why.

I am buying the kit, so I can't complain, but since it would cost
only pennies to do it at Elecraft it seems like it would be a
no-brainer if crimping is actually superior.

I would suggest that if someone does not have a precision APP crimp tool
that they simply solder the pins, despite the fact that in the long run,
cable flexing and vibration will eventually become problematic.  If the
crimp is not performed correctly, the flat mating surface will oftentimes
become distorted and out of alignment with the crimped portion.   If this
occurs, one will usually see a bend in the overall pin.  The bend carries
over to the mating surface when steated into the shell.  If that pin is also
mated with a similar bended pin, then all bets are off.

The APP connection is marginal for 20A DC circuits -- the kind of current
when the 100W K3 is transmitting at full power.  If the connector manages to
come loose while transmitting, the pin surface can form a weld spot.  The
underlying principle and quality of connection is 100% dependent on the
alignment of the two flat surfaces.   I absolutely detest APP connectors and
I have the best cable prep tools available.  However, I suppose use of the
connector can be forgiven in light of its growing popularity.  Even Collins
used riveted RCA jacks for the RF ports on the S-Line.  Nobody is perfect.

Most kit builders have a soldering iron, so they certainly
don't have to crimp
the PP connectors.

In your post you say, "Some of Elecraft's customers are
faced with having to
spend $50 for a tool to use only one time? Why?", although
they have a choice to
do it either way.  Why do you say that?  Elecraft does not
require them to use a
crimp tool.

What about the advertising claim "No-solder Kit?"
