Hello,
For our radio, we use airtime (v2.5.2) and Wordpress with the Onair2 theme.
We are using a wp plugin which connected to the airtime API, displays what is on the air and retrieves the image of the show.
The code is here: https://github.com/OliCat/onair-wp-plugin
A plugin that displays the week’s program on the same principle would undoubtedly be interesting.
Feel free to contribute to the existing code
