The following broadcasting associations and organisations currently provide programming on NPO Radio 4: AVROTROS, BNNVARA, EO, KRO-NCRV, MAX, NTR and VPRO.


Initially, the channel broadcast only during the evenings, with a segment produced by Teleac, but it now operates around the clock, providing surround sound transmissions via the internet and satellite.


The emphasis during the day was once all-complete works from both well- and lesser-known tracks; however, the station now focuses more on short segments from better-known classical repertoire. In the evening (around 8-11pm), a live concert is broadcast, on Saturday evening a regular live recording of an opera concert. Since 2015, live shows can be watched in the studio via a webcam.
