[Elecraft] PowerPoles

[Don Wilhelm]

If you do not have a proper crimping tool, solder the APP contacts. 
Soldering has its downside if used in high vibration environments (the 
wire will break where the wicked solder ends), but for applications 
where the wire is not subjected to vibration, soldering is better than 
connections made with an improvised crimping tool.
