[ARC5] The International System of Units (SI)

[Bill Cromwell]

Hi,

This topic has spread out across a couple of threads. I have started 
using the 'long form' more just because of the ambiguity. Newer hams 
seem to be more easily confused and I suppose that is to be expected. 
Somebody in one of the threads mentions the notes on schematics that 
defined the units and their abbreviations as used in the schematic. That 
tickled my own memory of how I became aware something more than a couple 
of weeks ago.

Milliherz are used by the WSPR and some of the other "takes all night 
for a callsign" crowd. It's not that they actually use a signal 
frequency of 1 or 2 millihertz but that they resolve frequencies to the 
nearest milliherz or fraction thereof. My hat's off to them but 
frequency measurement and control to that degree is it's own reward and 
is a waste of time for me the way I practice the hobby. All night to 
exchange a callsign? Harumph..

73,

Bill  KU8H
