[Elecraft] [OT} Running a KX3 station from a holiday trailer

[Al Sather]

I should also add that I have approximately a 10 foot run of #8 wire 
running from the batteries to the inside of the trailer, hoping I would 
not have a significant voltage drop. This will terminate with a PP 
distribution block. Total wire run should be less than 16 feet and 
closer to 12 feet.
