Shortwave Radiogram schedules, Thursday-Sunday


Hello friends

One change to our transmission schedule take effect this weekend: The Saturday (Friday in the Americas) broadcast at 0000-0030 UTC on 9955 kHz is no longer available. We hope we can return to 9955 in the future, because this frequency provided coverage from South America to northern Canada.

This week's program is in our usual MFSK32 and MFSK64, with ten MFSK64 images. If there are modes or experiments that you would like us to try to Shortwave Radiogram, let me know.

A video of last weekend's Shortwave Radiogram (program 206) is provided by Scott in Ontario (Friday 1300 UTC). 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 207, 3-6 June 2021, in MFSK modes as noted:
  1:42  MFSK32: Program preview
 2:48  Australia's MAVIS telescope: clearer than Hubble
 6:39  MFSK64: JAXA capsule will return samples from ISS*

13:22  This week's images*

28:40  MFSK32: Closing announcements

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK-64 text and image near the end of the broadcast.  It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on 5850 kHz (Wednesday evening in the Americas). Also look for a waterfall ID at the beginning of the show. .    @ThisIsAMusicSho

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!
