FWIW, all of my 30A PP connectors are soldered, not crimped, as originally recommended by Wayne for those who choose not to spend the money on a purpose-built crimper for PowerPole terminals. I have not had any trouble since I started soldering PP connectors for my KPA100 fifteen years ago. I

Re: [Elecraft] K3s - 80W on 160 - Resolved

In the past I installed quite a few power poles with a crimper that was not designed for it. Then a friend bought the purpose-built crimper, which I borrowed several times. HUGE difference. Makes it almost fun! My dear wife took note of this, and conspired with my friend to get one under the tree

I use PowerPole connectors for all DC wiring, not only in the shack, but also throughout the house, and including the dozens of accessories and appliances that run on outboard DC supplies. While a "proper crimper" is helpful, I've installed hundreds of pairs of power pole connectors using

Re: [Elecraft] K3s - 80W on 160 - Resolved

One does not need to jam too-large cable into the power pole connector. Do the power pole normally with the #10 zip cord. Then two or three inches away from the power pole, splice in two more parallel runs of the #10 zip cord. Solder and tape these splices. This will divide your voltage drop by

I’ll agree with Don: If you are going to use Andersen Power Pole connectors, you have to commit to getting a proper (yes, a proper) crimper. Yeah, they are not cheap, but the savings of time and frustration in assembling the connectors is worth the price. And, like any good tool, it’ll have

Re: [Elecraft] K3s - 80W on 160 - Resolved

All the APP connector blades (inserts) that I have seen which will take #10 or larger wire (30 amp) must be crimped. They have "fingers" that must be bent over the wire. Use a proper crimper for PowerPoles, substitutes will make a mess of the job and mess up the contacts. If you wish to use

PPs solder real well. Just keep the solder off the outer portion of the round part where the wire fits. Sent from my iPhone ...nr4c. bill > On Dec 20, 2016, at 5:34 PM, Gary Smith wrote: > > Hi Jim & the others who replied, > > This is a follow-up for someone in the >

Hi Jim & the others who replied, This is a follow-up for someone in the future who looks for the same solution. Yeah, the small amount of difference in the wattage is insignificant but considering all the radios I've owned, the low end of the bands were always the highest output. 10M was
