[aprssig] 12V wiring ideas

I do not question your conclusion or technical accuracy about crimp vs 
solder.   However, I do question some of the assumptions made in drawing 
this conclusion.   First, that the wire is suitable for crimping.  Then, 
that a truly good tool is available.  That the connector, tool and wire are 
compatible for the purpose and finally that the person doing the work is 
physically capable and understands what must happen.

I contend that this is likely the case in only a small fraction of hobby 
situations.  I think about the experiences I've had in the past thirty years 
and would never ever, as a hobby "elmer" ever suggest anything but solder. 
And that applies especially to me!
