[Elecraft] Soldering crimped connectors is not a good, thing.

I want to throw in the presence of possibly counterfeit connectors as well.

This is important; in evaluating suppliers for our adapters at Pro Audio 
Engineering we were sent a sample of non-Anderson PP connectors which 
just did not mate correctly with the real thing. The leaf spring under 
the contact was of insufficient preload to keep the pair mated under 
light tension, which also throws the reliability of the contact 
resistance into question.

We didn't find a problem with crimp retention, but that is so very 
specific to the actual ID of the ferrule and the gauge of the wire being 
crimped. It is possible that someone using a wire at the small end of 
the range for that specific contact could have a problem. It can be 
compelling to save 50% or more on a connector, but we ended up using 
Anderson PPs, and have had zero quality issues as a result.
