Hello friends,
I'm not a fan of too much sunlight, such as what we are experiencing now in the Northern Hemisphere. Still, it might create some interesting propagation between our Northern Hemisphere transmitters and receivers in the Southern Hemisphere, where sunlight is at a minimum.
Also during our Northern Hemisphere summers is noise from lightning and other atmospheric phenomena. In addition to the usual sources caused by humans and their devices. There will be a long stretch of MFSK32 text at the beginning of the broadcast this weekend. Please note how well the text survives noise, weak signals, and all the other degradations that make shortwave so much fun.
Videos of last weekend's Shortwave Radiogram (program 157) are provided by Scott in Ontario (Friday 1300 UTC) and Ralf in Germany (Sunday 2330 UTC -- showing the MFSK32 text heroically prevailing amid fading, noise, and a weak signal). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
This weekend's show is in the usual MFSK32 and MFSK64, with nine images (all MFSK64).
Here is the lineup for Shortwave Radiogram, program 158, 26-28 June 2020, in MFSK modes as noted:
