Shortwave Radiogram, 15-17 February 2019: Digital modes that survive dust storms

The International Space Station is transmitting SSTV again this weekend, until Sunday at  1725 UTC, on the usual 145.8 MHz (FM).
From your reports, I learned that last weekend’s Shortwave Radiogram segment of Olivia 64-2000 succeeded when the MFSK32 and 64 showed errors due to poor reception conditions.For most listeners, reception was good enough that the Olivia 64-2000 was not necessary.
This weekend, hoping for some instances of bad reception, we will transmit another segment of Olivia 64-2000 (with another reminder about the Winter SWL Fest, 28 Feb-2 Mar). There will also be another broadcast via the WINB DRM transmitter, today (Friday) at 1500 UTC, 13690 kHz, likely with the content of last weekend’s show.
Here is the lineup for Shortwave Radiogram, program 87, 15-17 February 2019, in modes as noted:
  1:41  MFSK32: Program preview
  2:53  Russia mulls test of disconnecting from the internet
  7:32  Olivia 64-2000: Winter SWL Fest reminder

New York and Pennsylvania NBEMS nets. Most weekends, as KD9XB, I check in to the New York NBEMS (Narrow Band Emergency Messaging Software) net Saturday at 1300 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1300 UTC on 3583 kHz USB. Check-ins are in Thor 22, and messages are in MFSK32. Messages usually use the Flmsg add-on to Fldigi. If you are a radio amateur in eastern North America, feel free to check in. Outside the region, use an SDR in the eastern USA to tune in and decode. You do not need Flmsg to check in, and most of the messages can be read without Flmsg. If you can decode the net, send me an email to , or tweet to @SWRadiogram , and I will let them know you are tuned in.
