A remote sense (Kelvin contact) to the inside to the radio would eliminate most of this IR drop debate.

Questions: 1. Does soldering make a molecular, gas tight connection? 2. Cant you clean the soldered connection with a solution that is a base to neutralize the acid. 3. It does stiffen the wire 4. Same as three. 5. Which method has the lowest resistance, measuring with a short piece or wire length to have the connector system dominate the measurement?

While many people recommend soldering crimped connectors, such as Anderson Power Poles, it is not a very good idea. The reason(s) it is neither required, nor desired, is partially as follows: 1. A PROPERLY crimped connection creates a molecular bond between the conductor and the connector that is more conductive than soldering. 2. The soldering process causes corrosion because even rosin core solder is slightly acidic. 3. The solder that flows into or onto the conductor (wire) causes it to stiffen and increases the probability that vibration or movement will cause the wire to break at that point. 4. The annealing of the copper wire is altered which also increases the possibility of wire breakage due to vibration or movement. It is absolutely necessary that the proper tool be used for the connection being crimped. If you are going to use a crimped connection it is imperative that you have a tool that matches the connector. If you do not have the proper tool then DO NOT use crimped connections.
