[Elecraft] Headlights with red lighting

[Fred Jensen]

The lights in the C-130 on our nighttime airborne missions in SE Asia 
were deep red to preserve our night vision, the trip to the jump target 
was in the dark.  The effect of any light above the bottom end of the 
visual spectrum on night vision is dramatic.  I'm a monochromat, I don't 
really know what "red" looks like to everyone else, and my dim light 
vision was really good, but anything higher in the spectrum killed mine 
just like all my troopers.  The fact that I can adjust the LCD 
brightness on my K3 is really cool, I normally run LCD at 2 or 3.

The one problem I have is I can't see the numbers on the keypad keys in 
any light.  Fortunately, I know what the keypad looks like. [:=)
