[Board] Updated Spreadsheet from Jan King

[Michelle Thompson]

Greetings all!

Many of us in the amateur satellite community are familiar with Jan King's
link budget spreadsheets.

Jan King has an updated version. It incorporates a large amount of content
from his commercial work that has been folded back into an amateur context.
The project addressed in this version is Open Research Institute's
microwave broadband digital DVB-S2/X transponder work. However, this
spreadsheet can be adapted for many different projects. I would like to
make sure that all of you know about the spreadsheet and are able to get an
updated copy of it.

The current version of this spreadsheet can be downloaded from here:

And a video walkthrough, recorded on 12 May 2021 with Michelle Thompson and
Wally Ritchie as the audience, can be found here:

Note: This is a long video! This video explains the entire spreadsheet.
There's action items and changes that are discussed in the video. Essential
functionality and overall structure will stay the same.

For an introduction to the open source amateur satellite system that this
link budget is being developed for, please see the introduction to this
video presentation.
