Much of the value of the GNU Radio Conference is in the interactions between all participants of the event. In moving to a virtual event one of our core focuses was on supporting these interactions as much as possible.
The conference will make heavy use of the “Matrix” chat system which is used year-round for GNU Radio development and community discussions. There are rooms for general chat, discussions and Q&A for main track talks, individual sponsors, and topical breakouts.
We strongly recommend that you join in the chat where possible.
Once you have logged in you should be seeing the main GRCon discussion page. The full list of GRCon rooms are located at:
The GNU Radio Code of Conduct also applies to GRCon Chat Rooms.
Go to https://chat.gnuradio.org and create a new Account. No information other than username and password are required, though an email address is helpful for password recovery.
Matrix does support chat encryption and will ask you to make a backup of your private key information in case you lose access to your existing login.
Many current members of the GNU Radio Chat community have mentioned the phone apps are a quick and easy way to communicate.
The homeserver of the GNU Radio Chat is https://gnuradio.matrix.ungleich.cloud. See below for an example of how to create an account using the GNU Radio homeserver on the Element Desktop Client (to sign-in you click “Sign in instead”).
We have several chat rooms setup for interaction during GRCon. All chat rooms will be monitored/moderated during the event. Many chat rooms will remain active until 1 week after the conference, and some will persist beyond the conference.
We will host the following chat rooms during GRCon. In addition, each sponsor will have a separate chat room, see below for more information.
The easiest way to see all the rooms is to visit https://chat.gnuradio.org/#/+grcon:gnuradio.org (requires account)

The GNU Radio chat includes strong encryption between users (disabled on the public channels). When you first log into your account on a second computer or browser the website/app will prompt you to verify your login using another verified session. Here is a video demonstrating the process:
A direct message can be sent to a user by searching for them under “People”.

A #grcon-helpdesk channel has been set up as a way of quickly addressing any questions, concerns, or suggestions you may have during the event. Several conference organizers and volunteers will be monitoring that channel during the event.
GRCon20 is offering virtual workshops for Full and Student Registrants. Workshop Information can be found here.
Most virtual workshops will be conducted via Big Blue Button, an open source web conferencing system for online learning. Links will be provided to attendees who sign-up prior to the workshop’s start.
To ensure that Q&A is possible and that the virtual workshop platform gives a good experience, each workshop is currently limited to 100 attendees (except the OpenCPI talks which are limited to 20 due to hardware limits). Waitlists are enabled and we will be tracking demand for each workshop.
You can preview the workshop platform and check that it works for you at http://test.bigbluebutton.org
Sign-up for each workshop will remain open until the day before it is scheduled here.

Yes, all the talks will be available on the GNU Radio YouTube channel after the conference.
