OTOH, that's just failure. The efficiency of transmission has got to
be a whole other issue - which I have no clue about.

Again done correctly, the crimp will have almost no differance than a single
piece of wire. The solder will have a very small ammount of resistance.

Probably did not come out the way I want it to, but the crimp will have less
resistance than a soldered joint.


That's why a proper soldered joint is first crimped. Solder holds and
seals the connection. That's the way I was taught.

I can make some pretty poor soldering at times, but I can also use proper
technique. I passed a NASA soldering school class.

Who says a solder connection does not need proper strain relief to prevent
vibration failure.

I have soldered large battery cables using hundreds of watts, as well as
1.5 mm caps to boards.

Our "radio guy" for all the state 2-way radios installs them with
crimped connections as far as hooking them into the car electrical
system, no soldering.
