Shortwave Radiogram, weekend schedules


Hello friends
So this weekend we reach the milestone -- or kilometrestone -- of 200 programs. Thank you for tuning in and decoding, for your reports and interest. These have kept Shortwave Radiogram going since it succeeded VOA Radiogram in the summer of 2017.

A video of last weekend's Shortwave Radiogram (program 199) is provided by Scott in Ontario (Friday 1300 UTC). Another video, by Georgi in Bulgaria, lets us hear the interference on 15765 kHz just after the April 10 Shortwave Radiogram on 15770 kHz, as well as an amazing variety of signals and music in the 19-meter band.  The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 200, 15-18 April 2021, in MFSK modes as noted:
 1:42  MFSK32: Program preview (with a special image)*
 4:20  New technique for injection-molded glass objects*
10:07  MFSK64: New geophysical observatory at HAARP site*
15:23  This week's images*
27:30  MFSK32: Closing announcements (and look for a surprise mode)

* with image(s)

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK text and image near the end of the broadcast.

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 1200 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1130 UTC on 3583 kHz USB. Check-ins are usually in Thor 22, and messages are in MFSK32. Messages generally 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. USEast NBEMS Net: Please also note the USEast NBEMS Net, Wednesdays 2300 UTC (7 pm EDT) on 3536 kHz USB.
Thanks for your reception reports!
