Something to add to the list:
MHz Mega Hertz mHz milli Hertz
These are often used interchangeably, where in some cases it is obvious what is meant, in other case you are left guessing. The SI system works well when properly used.
You see someone stating that they are on 432.00 mHz when they really mean 432.00 MHz. A very big difference.

GREAT IDEA..................I'll wager I get accused of using more
acronyms
than anyone! In my Symposium Paper, I attempted to spell out all the acronyms I did use, but I'm not sure I did in my presentation and if so, the slides probably went by too fast for those to be "digested!." So I went back and resurrected the acronyms I used for the GOLF system design introduction and have included those in this message as my 'contribution' to the cause............

It's a good idea, Gerald--I don't remember such a list, but it could
have
been. Could you start the ball rolling by sending out the list of terms that you already wrote down which you did not know? Sometimes it's hard for those of us steeped in them to realize what is unknown.

Abbreviations and acronyms are a real headache for me from time to
time.
I was told that in the past the AMSAT Journal sometimes printed a table
of
abbreviations used frequently. I have some Journals from Sept/Oct 2019
to
current issue, but do not include such table.
Is there such table available and where may I find it, please?
I listen to Saturday's Symposium and was overwhelmed with the terms
used.
I wrote down and looked up later a few of the terms. I realize that it probably take time to learn, but a list or table would help!
Thanks, and 73 to all.
