[Elecraft] RE; How well does the K3 work with lower power supply voltage . . .

[Lynn W. Taylor, WB6UUT]

Slightly related...

When cars were all 6 volts (I'm not quite old enough to remember when 
that was common) the wiring would get a little old, headlights would get 
dim, and you could fix that by installing an 8 volt battery and 
adjusting the voltage regulator so it'd charge.

I mention this, because I saw that Costco has 8 volt lead-acid batteries 
from Interstate Batteries.

An 8 volt and a 6 volt will give you 14 volts, and no boosters necessary.
