[Elecraft] normal K3 voltage drop on TX

[Kenneth Talbott]

Never solder PSU connectors - overcurrent can heat the joint and drop molten
solder where you least desire it!

Bob,
Crimped connections are superior to soldered connections in a high
vibration, high stress environment. 
The solder will fracture after exposure to vibration and/or temperature
cycles. With a proper crimp tool (not the one from Harbor Freight!) the
resistance of a proper crimped connection will be no higher than 
that of a soldered connection.   The TE/Amp PROIII hand crimp tool is $213
at Digikey...The Amphenol
hex die crimper for RG-8, RG213, etc. is $112.

But, soldered connections are fine for a ham shack.
