[Elecraft] Voltage drop in DX Power to K3

[Leroy Buller]

40 inches of power cable.  In my experiences,  that could be an issue
depending on the gauge of the wire.  I used a long cable 12 gauge and had
issues.  Went to 24 inches number 10 gauge and voltage drop significantly
improved.  The resustace does not have to be large to cause a voltage  drop
