[Elecraft] K3 - Power cable voltage drop

[Bill Frantz]

A simple reality test for a volt meter is to measure a fresh 
battery. Zinc/carbon or Alkaline should show about 1.56 volts. 
(I learned this test from the bias setting instructions for a 
Dynakit Stereo 70 amplifier. They built the amp so the test 
point read 1.56 volts when the bias is correctly set and 
suggested calibrating your meter with a battery. In that era, 
the zinc/carbon battery was what ran almost all of the 
flashlights (torches for for English speakers) in the world.
