Notes about the video meetings

Saturday 17 October 2020, 20:00 UTC

After some technical difficulties with Big Blue Button, we moved to Zoom and succeeded in doing the planned agenda:

• Brief walk-through of Simulation example: FSK

• Presentation of gr-RTTY-basics package

   https://github.com/duggabe/gr-RTTY-basics

   https://github.com/duggabe/gr-webserver

• Audio loopback demo
• Live Over-the-Air demo

The time (20:00 UTC) proved to be too late for participants East of Greenwich, so an earlier one was scheduled for 7 November.

Saturday 7 November 16:00 UTC

The meeting followed the agenda above. There was a minor audio difficulty with the loopback, but I proceeded to present the Over-the-Air demo successfully.
