[Elecraft] units of measurement, explained

[Steve Jackson]

uuF was used to spec cap values in tube equipment. 
The introduction of semiconductors forced a conversion
to use the 'pico' prefix.

Same with hertz.  Tube gear measured frequency in
cycles per second.  The transistor changed all of
that.

Today, the use of surface mount parts has caused the
need for 'nano.'
