[Elecraft] Voltage drop in DX Power to K3

[N4ZR]

I've had an e-mail exchange with West Mountain Radio.  Measured the 
voltage drop inside the 4005i at only .08 volts at 100 watts key down.  
My power cable from the 4500i to the K3 measures 0.3 ohms on each 
conductor, which at 20 amps should only yield a 1.2 volt drop, right?  I 
don't know where the other volt plus of drop is coming from.  The cable 
is 40 inches long, and only minor shortening is possible.  It is about 
the largest wire that will fit in the Powerpoles on both the K3 and the 
4005i.

Suggestions welcome
