[Ground-station] Thursday Office Hours - Time/Date/Agenda - call for additional items

[Alan Rich]

Hi Salvatore et Michelle,

Michelle, Thank you very much for putting us in contact.

Salvatore - I will let you lead this. I have a reasonably good knowledge of
traditional "spreadsheet" link budgets but I am not strong in
software/Python.  I think the Jupyter / Python approach is a very good one
however. You can email me or contact me on the Slack application if you
like.

Michelle, I will assess adapting the Jan King link budget calculations to
Octave, the free/open source version of MatLab. This is easier for me.to
approach.

Alan
