Czech public radio ‘Český Rozhlas‘ is stepping up its information campaign for listeners receiving mediumwave programmes, ahead of the planned switch-off of transmitters by the end of 2021. Since 1 November, more announcements have been broadcast to warn users and a call centre has been set up to explain the possible listening alternatives (from FM to DAB). In the run-up to Christmas, public radio will launch an intensive advertising campaign in the print media and online magazines on 22 November to promote the purchase of digital DAB receivers to replace analogue radio. The shift away from medium-wave has been underway since the 2000s, affecting countries that have an alternative FM network or are in the process of creating one in DAB. But AM (amplitude modulation) still remains a resource for countries with large territorial coverage that can reach the entire population with a few installations.
