[ARC5] Cost of sets - 1950 and 2010

[Henry Mei'l's]

HelloNeil, ZL1ANM

Don't know if it's true or not, but I heard and read  that one of the Mars 
landings messed up because velocity and or distance calculations switched 
over to feet-mph instead of meters-km/hr -- either a computer or human 
glitch.

Europeans shake their heads about the Anglo-Saxon use of  feet, inches etc.
BUT one advantage is that an inch is the rough quivalent of the top joint of 
your thumb, the foot
... , the yard the length of your extended arm to mid-chest, etc.

But metric is the only real way to go -- I even feel taller when I give my 
height in centimeters ;0)
(Still, I can't help but feel that a centimeter is an undernourished inch 
and a kilometer is stingy mile.)

Would you be interested in trying for a CW sked on 14, 18 or 21 MHz?

Henry, OZ1UF Cph.
