How in the world did a change to solid state affect a naming convention? 1
Hz = 1 cps, regardless of the circuit devices. 1 uuf ("micro micro farad")
= 1 pf, regardless of the devices used in the circuit. I am baffled by this
notion. Can you provide more evidence? 73 de Brian W3BW

Subject: [Elecraft] units of measurement, explained
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.'
