Many thanks to SWLing Post<\/em> contributor Dennis Dura, who shares the following article from Radio World<\/a> about the impending shutdown of Canada\u2019s iconic CHU shortwave time station.<\/p>\n

We’ve covered CHU\u2019s imminent closure several<\/a> times here on the SWLing Post<\/em>, but this Radio World piece provides a particularly nice overview of the station\u2019s history, purpose, and enduring significance to the radio community. It\u2019s well worth a read, especially if CHU has ever been one of those familiar signals on your dial.<\/p>\n
