[Elecraft] Astron VS-35M Powwer Supply V-

[Buck]

The Kenwood TS590 runs about a foot of 12 ga connected to the power 
supply and then the rest of the power line is double 12 ga wires to the 
radio.  Could you reverse that and run double wire until right before 
the power pole and then a short single wire into the radio?  That would 
reduce the over-all resistance in the power line and still use the 
single power pole jack on the radio.

My power supply is a 35A Astron and I use the stock Elecraft-supplied 
power line.  My voltage drops at least a half volt on key down.
