[Elecraft] Silent power supply for a K3s

[Bob McGraw K4TAX]

Regarding "heavy gauge wire", I suggest one measure the voltage drop 
using a DVM connected direct between the power supply Pos terminal and 
the radio Pos terminal.   Likewise do the same for the Neg DC line.   
Put the radio in CW mode and close the key for rated output.    If one 
finds more than 0.25 volts drop in either the Pos or Neg line, I'd say 
that attention to the power cable and connectors would be in order.   
Also measure between radio ground and power supply ground.   Again a 
voltage value greater than 0.25 volts indicates attention to the power 
distribution system and station equipment grounding is needed.
