Shortwave Radiogram this weekend is in MFSK32 and MFSK64, and a brief segment in Olivia 64-2000. If your signal is so bad that you can’t hear anything, try the Olivia 64-2000 anyway, at seven minutes into the show, and you might see text printing out.
Separate from this weekend’s normal broadcast, today (Friday) at 1500-1530 UTC there will be special content, including some super-fast modes on WINB’s DRM transmitter, 13690 kHz.

This is a convoluted way to receive text and images, but fun when it works. Details via the URL above.
