Re: [Elecraft] K3 just goes off - SOLVED
Apparently, based on the input here, I'm doing it all wrong by crimp and solder. But since I started that, I've not had a failure (back when Molex was king). Most times the actual connection is secured from motion (not vibration) while the tails are allowed to move, if needed. Yes, I use the proper crimp tool for the connector, but I doubt it is certified. Rick NHC -Original Message- From: Fred Townsend Rick I use Teflon wire for my battery leads. Teflon wire is silver plated. The Anderson power poles are silver plated too. While I can not quote chapter and verse most NASA applications require crimp (with certified crimper). There are at least two reasons. Solder wets and runs within silver braid very quickly so the solder runs into the insulated part of the wire and causes brittle fractures inside the insulation.

Re: [Elecraft] K3 just goes off - SOLVED
I have been told, sometimes by reliable sources, that proper crimping actually pressure welds the contact to the copper wire. Soldering on the other hand heats the copper to around 750F and it then cools fairly fast which hardens it. Then, under vibration, it fatigues and breaks. I've heard this said about soldering dipole connections too. I can tell you that NASA crimped [very carefully] and did not solder on the Apollo program. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org On 6/24/2012 4:55 PM, Hisashi T Fujinaka wrote: > What does the maritime industry use?

Re: [Elecraft] K3 just goes off - SOLVED
I agree about the inexpensive crimping tools...possibly not about prohibitively expensive. A small array of adequate crimping tools can cost several hundred dollars which I don't think is too much when you consider the money spent on just one high end transceiver. I think those flat plate crimpers you see in the automotive department at the hardware store ought to be outlawed from the hamshack.

Re: [Elecraft] K3 just goes off - SOLVED
Crimps are good if they are properly done with proper sized terminals and proper crimping tools for that type and size of terminal - there is no "one size fits all" crimping tool, and I believe there lies the problem with amateurs using crimped terminals - buying the proper crimping tool for each and every crimp terminal would be prohibitively expensive. Yes, there are consumer grade "universal"crimping tools and terminals, but they grip the wire over only a short distance - professional crimps will make solid contact with the wire over a larger area, and will be a gas-tight connection where corrosion cannot get in. I believe soldering is a better alternative for amateur work. Soldering does have one disadvantage and that is solder will be wicked up the stranded wire for a small distance, AND if the wire is subject to vibration at that point, the wire will eventually break right where the wicked solder ends (under the insulation where that break cannot be immediately noticed). So in high vibration environments such as avionics, soldering is a definite "no-no", but at the home station installation where the wires are seldom moved, soldering should be just as good or better than properly crimped terminals. In your mobile installations, you might want to consider either crimping or supporting the wire for about 3 inches away from the soldered terminal. 73, Don W3FPR On 6/24/2012 7:55 PM, Hisashi T Fujinaka wrote: > What does the maritime industry use?

Re: [Elecraft] K3 just goes off - SOLVED
You've hit on why the auto industry uses crimp also (probably because of cost as much as anything too). When a wire is soldered, a bit of the solder tins up the wire strands and vibration or flexing can quickly cause the wire to break and negate the reason we use stranded wire in the first place.

Absolutely. I bought a power cable from West Mountain and one of the leads (the red one) just fell out of the crimp connector. So much for trusting the "professional".

Re: [Elecraft] K3 just goes off - SOLVED
Glad you found it Lee! Many problems similar to this are caused by a bad crimp job on the Anderson connectors. I would encourage everyone to get the more expensive crimp tools with the right dies for the various amperage connectors used. Soldering is fine too but not needed if the cable is crimped properly.

Re: [Elecraft] K3 just goes off - SOLVED
Recently, I built a new power cable...a shorter cable with automotive spade fuses. The Radio Shack Spade Fuse Holders are defective. Would not seat the fuse properly. Thus, the connection malfunctioned. I will be replacing those soon.

If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine?
