[Boatanchors] WTB: Xtals (even mHz)

[Bob W5UQ]

Oh I don't question SI Mac.

In college, many many years ago,(more than I want to admit) we all had 
to learn the correct SI language.  Or our prof got really upset.  And I 
do seem to remember the capital M and m being like you say.  Just forgot 
it.

Also, I was just adding another method  that has been taught.  Not that 
it's correct.  HI. But it may explain why some used the lower case m.

So, I will do MHz from now on... okey dokey? And thanks for letting us 
know so we can avoid being incorrect. :-)

and the BEAT goes onnnnnn....
