[Elecraft] K3 dumb Q about PPM, less dumb one about NB

[Garry Shapiro]

I think you are commenting on the widespread, confusing use of "mHz" 
which literally means milli-Hz. How this "unit" came to substitute for 
MHz is a mystery to me. As an engineer, I tried to use what I was 
taught--lower-case multipliers are <1 and upper-case multipliers are >1. 
"K" and "k" appear to have gone the same route as "M" and "m". I don't 
know why or when these changed--probably when I was not looking.
