Hello friends,

The first news story on this week’s Shortwave Radiogram is about Canada’s plans to close the shortwave time station CHU in June. Many of us have tuned in CHU over the decades to get a an accurate time reading. In my eastern US location, CHU is often easier to hear than WWV.

I have often thought that our MFSK32 modes could be added to CHU or WWV for time and general announcements. In difficult reception conditions, text information is more likely to be conveyed to the listener than a voice announcement.

CHU, with its three shortwave frequencies, could be a wonderful laboratory to explore the capabilities of HF, especially as an alternative to the internet, which may not always be «always on.»

A video of last week’s Shortwave Radiogram (program 450) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 451, 28 May-4 June 2026, in MFSK modes as noted:

 1:43  MFSK32: Program preview 
 2:53  MFSK32: Canada’s CHU time station will close 
 5:18  MFSK64: Cities seek to reduce light pollution, see stars
12:35  MFSK64: This week’s images
28:15  MFSK32: Closing announcements
