Malcolm brings up a very good point. All connections should be fitted with a proper lug which is crimped with a proper tool, depending on wire size and the terminal to which it will be attached, AND all terminals should be soldered. I make no exceptions to this practice. The crimp connection is a mechanical connection, the soldering is the electrical connection.

One additional point I've found to be most beneficial is to run a dedicated ground wire between the ground terminal on the radio to the ground terminal on the power supply. I do not rely on the DC negative to serve as ground between the radio and power supply.

Hi All


As a matter of standard practice all my crimp contact junctions are soldered as 
well as being crimped using a good quality tool.

I hope this note provides adequate guidance.
