"In the first section, a set of tools for content production, recording and transmission is introduced. Beyond simply providing a list of software already used by radios—such as audio editing and broadcast automation software—this manual’s aim is to develop a comprehensive proposal for decentralized and collaborative forms of working. Nearly all of the software presented here is free software, because only free software guarantees radios’ autonomy, privacy and security, and allows them to freely adapt it to the needs of specific contexts. Moreover, while (financially) supporting developers is recommended, most of the software programs presented here are available for free. In the manual’s second part, we then go on to discuss ten strategies that radios can use in their communication practices to guarantee freedom of opinion and access to information and that should allow them to establish a relevant position in the post-pandemic media panorama. These strategies were identified and systematized based on experiences that have already been creatively making inroads into radio communication, allowing us to tackle numerous challenges related to the dissemination of information. The lessons learned are invaluable and we aim to build upon them." (Introduction)
