[Elecraft] KX3 Display LEDs

[Rick Dettinger]

I think that mil is short for milli inch, which is really mixing  
systems.
I think that power folks do even worse.  Wires larger than 4/0 are  
given in circular mils, or cm.  When I started with a power company 42  
years ago, one thousand circular mils was MCM, where the M was from  
Roman Numerals for thousand.  That was confusing, as it could also  
refer to Mega, so the M was changed to K for Kilo, so we had Kcmils.
