Shortwave Radiogram, weekend schedules


Hello friends

Shortwave Radiogram received some publicity on the May 7th edition of Amateur Radio Newsline. The audio and text are available here and the video version here. Thanks to Benn Kobb, AK4AV, for presenting the report.

Videos of last weekend's Shortwave Radiogram (program 203) are provided by Scott in Ontario (Friday 1300 UTC), Frigid in Virginia (Saturday 1330 UTC), and kurma10goo in Japan (the MFSK32 segment Sunday 0800 UTC on 5850 kHz). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend we will again demonstrate text transmission in a language other than English. It will be Spanish, so less complex (to our eyes) than the Khmer and Burmese we tried a few weeks ago. But there are diacritics (accent marks). These require the UTF-8 character set, which is default in Fldigi and TIVAR. If for some reason the diacritics do not display correctly, copy what you do decode in the Fldigi receive pane to a word process, and they might be correct there. ¿No hablas español? A link to an English version of the VOA story is also provided. 

Here is the lineup for Shortwave Radiogram, program 204, 13-16 May 2021, in MFSK modes as noted:
 1:41  MFSK32: Program preview
 2:43  Large US offshore wind project (in Spanish)
 6:31  MFSK64: Method for predicting solar radio flux
10:14  This week's images
28:39  MFSK32: Closing announcements

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. It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on 5850 kHz (Wednesday evening in the Americas) and a new time also on WRMI, Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) .

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!
