[Elecraft] Power Pole connectors

[Harry Yingst via Elecraft]

I have to agree with the crimping of PP connectors and in Crimping in general.
It's my understanding that PP need the ability to flex a little to function properly.Crimp tools seem expensive at first, but they are cheap once you realize the ease of use.

I tried soldering PP in the past and they never seemed to mate quite right, the crimped ones work well.

A proper crimp is far superior to solder! (Let the flames begin.)  The
solder will wick up your stranded wire and make a solid conductor of your
nice flexible wire.  The additional solid length will impart even more
torque on the APP connection.  Perhaps more importantly for power in
general, an overcurrent condition will heat the junction and melt the solder
which will proceed to flow into the most unwelcome places!  If you only own
one crimper, make it the West Mountain crimp tool for APP.

PowerPoles are not fragile, when correctly assembled/soldered. I think there
is an issue, either with your assembly to the lead or possibly with the
units mounted on the PCB in the K3 (it has been known to be in the K3).

Although I crimp all mine (well worth getting the West Mountain Radio Deluxe
crimp tool if your going to use a lot of APPs) I have to use a reasonable
