This is the time of year when the time changes and frequency changes can complicate our shortwave listening. In most of North America, clocks will move forward one hour on Sunday, March 12. The only impact this weekend is that the "red-eye" transmission of the Shortwave Radiogram will be one hour later by local time, e.g. 4:00 am EDT, because it stays at the same UTC time. The Mighty KBC broadcast also stays at 2200-2400 UTC Sunday, so it will be at 6-8 pm EDT starting this weekend.
Most of Europe will change clocks forward on March 26. That same date is the beginning of the A23 shortwave frequency season. More on that later this month.
Spring in the Northern Hemisphere also means flowers are blooming -- somewhat early this year due to the warm temperatures. This provides an abundant supply of flower photos which will be transmitted as MFSK64 images in the next few weeks. I hope we don't suffer from flower fatigue by the time we get through April.
The present season is also changing gray (grey) line propagation on HF (shortwave). Chris in New Zealand sent an email report of the reception of the Friday 0530-0600 UTC show on 7780 kHz (see below). This 7780 frequency was reliable for New Zealand and Australia when it was used for the Monday 0800 UTC transmission, but now WRMI uses that time and frequency for Voice of Indonesia.
A video of last weekend's Shortwave Radiogram (program 294) is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. (We miss the weekly analysis provided by Roger in Germany, who is on sabbatical.)
Here is the lineup for Shortwave Radiogram, program 295, 10-13 March 2023, in MFSK modes as noted:
1:37 MFSK32: Program preview
2:45 MFSK32: Research: First Americans arrived ~15000 years ago
