CBC Radio Overnight
At the top of each hour, a regular CBC news update is aired, lasting four and a half minutes.Previous hosts of the program included Cathy Haag, Bernie MacNamee, Pep Philpott, and Jeff Goodes.[2] Prior to the program's launch, CBC Radio One signed off during the overnight hours.[4] CBC Radio Overnight may, however, be preempted in some markets when the CBC needs to temporarily shut down a local transmitter for maintenance, as overnight transmitter repairs are less disruptive than a daytime shutdown.The remainder of the block is filled with programs from Australia's ABC Radio National and the BBC World Service; some programming from RTÉ Radio 1 and Deutsche Welle also airs on weekends.
