Shortwave Radiogram schedules, Friday-Sunday


Hello friends

Last week's experiment with text in the Burmese languages went well. It seems the Burmese were decoded successfully just about everywhere -- except Myanmar. But, then, we don't have any transmitters with good reception in Southeast Asia. It was decoded in Ireland using the TIVAR Android app and in Cuba using a simple portable radio placed next to a laptop computer.

In any case, the Burmese experiment was timely given Myanmar's current crackdown on online news.

A video of last weekend's Shortwave Radiogram (program 199) is provided by Scott in Ontario (Sunday 0800 UTC on 5850 kHz). And Matt KD8TTE produced this video about Shortwave Radiogram. The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.

This weekend, we will keep it simple, with no exotic alphabets, no HTML, no Flmag, and no surprise mode. Just text and images in our usual MFSK32 and MFSK64. And if you like to decode images, program 199 will have eleven of them (1 x MFSK32 and 10 x MFSK64).

Here is the lineup for Shortwave Radiogram, program 199, 8-11 April 2021, in MFSK modes as noted:

 1:43  MFSK32: Program preview
 2:46  Biodegradable plastic from fisheries waste*
 7:57  MFSK64: Blinken affirms the independence of VOA
11:22  This week's images*
28:35  MFSK32: Closing announcements

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!
