I am rather curious about the use of the term KOH by some forum posters to refer to kilohertz. I have always seen the term kilohertz abbreviated as KHZ or KHz.

Is the KOH term in common usage in some other parts of the world than where I have been?

Two examples of this usage can be seen as follows:

1) By Waqar Zaka in this posting as follows:

"iam using At89c52 , MT8816 , Crsytal of 11.05KOH .."

2) By Lance Austin in this post as follows:

"Controller Atmel 89c51"
"Crsytal 11.05KOH"

Can anyone explain this usage to me?
