Going live on a social network is an event: it starts, it ends, and in between nothing happens. An antenna runs. Your playlists broadcast all week, and Sunday's microphone simply takes over.

The three sources, the one-source-on-air rule, the automatic pause and resume of the grid, and the microphone lock with its message all exist as shown. The titles and times are examples.
The live stream lasts an hour. The station does not stop for the rest of the week.
On Sunday at eleven, everybody is there. On Tuesday evening, the person who can no longer travel has nothing to listen to, and neither does the one living six thousand kilometres away. A weekly livestream does not fill a week.
It is the classic broadcasting accident: the playlist is still running when the microphone opens, and both go out together. You find out from a listener's message, ten minutes later.
Half of a livestream's audience is lost before arriving: the link is in a message from three weeks ago, the video asks for an account, the app wants installing. Every obstacle costs listeners who had already made the effort to look.
Audio broadcasting is a field where more gets promised than delivered. Here is the line.
Upload three recordings, make a playlist, put it on two slots. On Sunday, take the microphone: the grid will step aside by itself.
