Does the K3 come with the Anderson power poles already installed or at
least in the kit? Tnx Tom CX7TT _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

Hi
The K3 has a PowerPole connector on the back of the radio and includes a kit to build up a 5 ft cable to plug into the radio. The power supply end is not supplied so you will need to connect the bare wires to your power supply or supply your own connector for your power supply. The cable kit includes 5 ft of #12 red/black zip cord, a set of red and black PowerPole connectors with terminal pins and instructions. The instructions recommend soldering the pins.

Tom,
You will have to heat up the soldering iron for this one. They give you the connectors and cable...no fuses or fuse holders. You will have to crimp and solder.

If you can't find any Common Sense, ask for help from somebody who has some Common Sense.

The connector was *not* installed on the cable in my K3 kit.

Others have given you the answer you were searching for, but I'll just chime in
to say that during my K3 wait (June till February), I made a cable of 10 ga. zip, with an in-line fuse holder and PowerPoles on each end. I have a West Mountain Radio crimper available, so I crimped then soldered each terminal. The Elecraft power cable kit is still in its bag, waiting for another project.

> You either crimp or Solder - not both
While it may be easy to prove that doing both is redundant, I see no reason why one *can't* do both, provided you crimp before soldering. I find it rather odd to make such a firm distinction. If I'm planning ahead and remember to bring the crimpers home from work, I'll typically just crimp. Otherwise, I just solder. Sometimes, though, I'll get picky and do both, such as on lines that will be carrying a fair bit of power. 73, Mike KW1ND _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

You are welcome to do both - as long as you don't compromise the
contact fit inside the housing. As to whether its worst or even advisable to do both... I've had people tell me that soldering hardens the point where the wire joins the contact and effectively weakens it, because strands can break at that point. I have to say, I would have thought defence contractors would solder as well as crimp, if that was considered worthwhile. FWIW - I havn't soldered any of my crimped APPs. -- Study without desire spoils the memory, and it retains nothing that it takes in. -- Leonardo da Vinci On 17 Mar 2008, at 17:33, Mike B wrote: >> You either crimp or Solder - not both > > While it may be easy to prove that doing both is redundant, I see no > reason why one *can't* do both, provided you crimp before > soldering.

I crimp and solder. But an explanation is in order: I begin by crimping the PowerPole connector to the stranded wire. When the crimp is complete, I then apply silver bearing solder ONLY to the very tip of the stranded wire where it butts up against the connector. The wire in the area of the crimp has NO solder and this is important to ensure that wire stresses due to cable movement do not break the wire as if it was a solid-conductor. So, it's the best of two worlds as flexibility at the crimp is maintained and I can be sure that long-term resistive loss is minimized by the small application of solder. When using this method, it's critical that the stranded wire does not "wick" the solder up to the crimp point and that's another reason why I use silver bearing solder as it tendency to flow along the wire is impeded more so than with standard lead/tin solder.

> You either crimp or Solder - not both
Why not? I've done both on all my crimped connections for years. Crimping breaks through any oxidation in the wire and terminal as well as providing mechanical strength. Soldering adds to both of these as well as reducing the potential for further oxidation (and increased resistance) between the wire and terminal because they are no longer exposed to the environment. Now, if one doesn't have the proper crimping tool and risks distorting the terminal and its fit in the housing or interconnection with its mating terminal, then only soldering may be best. Or, if soldering is not practical for some reason, then crimping is fine. In that case, some dielectric grease on the parts before crimping will help minimize future oxidation and resistance build up. Most of our radio environments are limited enough so lessen the effects of oxidation and mechanical rigidity. But crimping and soldering is so easy to do, why not quickly provide the added margin? 73, Ed - W0YK _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Power pole connectors are "new technology" to many of us. Given the problems I've had with past crimping tools, the first couple crimps with a new tool/connector are bad. That shoots down the two connectors supplied. So I guess if I had to buy a tool, I'd also get a bunch of "spare" connectors too. Not the scenerio I like for a $2K rig. Not an big deal though. 73 de Brian/K3KO. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

OK, we've established that the kit rigs require you to assemble the APPs
on the wire to make the power cable. Same deal for the factory assembled rigs or do they come with finished power cables? - Keith N1AS - - K2 5411.ssb.100 - - K3 Wave 3 (soon) - _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

The assembled K3's come with an assembled power cable, you just need
to finish the battery/power supply side.

I would far prefer a factory pre-assembled power cable, given the expense of the correct crimp tool and I far prefer crimping to soldering to a cable with no strain relief. ps I've probably crimped and soldered 100s of thousands of wires. But this is not a crimp tool in my armoury.

Don't over complicate it. I just used a plain old wire crimper and solder.
If you want some more strain relief, put some heat shrink tubing over the connector and for about 6 inches up the wire. Use big tubing at the connector and overlap it over smaller tubing up the wire. You might have to overlap a couple of different sizes to get it to be snug but it will be very strong. A drop of hot glue on the end of the power pole would also help. If you could see the Mickey Mouse job Yaesu did on the $4000 Quadra control cables or the pathetic and wimpy connector TenTec used for the Orion, you wouldn't feel so bad about the power poles. k4ia "Buck" K3 #101 Fredericksburg, VA **************It's Tax Time!
