Shortwave Radiogram, weekend schedules


Hello friends

Did we survive the time changes and frequency changes of Spring 2021? The only new frequency this weekend is the Friday 1500-1530 UTC DRM transmission from WINB Pennsylvania, on new 15750 kHz, replacing 13655, for those of you who have a way to decode DRM. Also, be aware of new local times for some of the broadcasts.

In the analog shortwave world, reception sees to be improving as spring becomes established. A video of last weekend's Shortwave Radiogram (program 197) is provided by Scott in Ontario (Sunday 0800 UTC). The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.

This weekend, no Flmsg. The only "twist" will be some text in Burmese, the main language of Myanmar, where the internet has lately been disrupted.  The Burmese will require the UTF-8 character set, which is the default in Fldigi, TIVAR, and AndFlmsg -- and, I am informed, also now in MultiPSK.

Here is the lineup for Shortwave Radiogram, program 198, 1-4 April 2021, in MFSK modes as noted:
 1:43  MFSK32: Program preview
 2:51  Facebook, Google announce plans for undersea cables
 5:40  Excerpt of Burmese-language text
 9:50  MFSK64: Arctic lightning strikes triple over past decade
13:08  This week's images
28:06  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!
