[Elecraft] normal K3 voltage drop on TX

[Bob McGraw - K4TAX]

Properly it must be crimped   A N  D   soldered.  Both are required.   
Are you saying a crimped and soldered connection is worse than a crimped 
only connection?

My military experience says there first must be a mechanical connection 
made {crimp or wrap} and then follow with an electrical connection 
{solder}.   And RCA stipulated this practice in all of their broadcast 
equipment.
