Shortwave Radiogram, Saturday and Sunday schedules

Hello friends,

The Vienna Wireless Society, the amateur radio club in Vienna, Virginia, near Washington DC, kindly invited me to speak to their meeting on September 24 about Shortwave Radiogram, including its history, goals, and great audience. A video of that presentation is available at

It's hard to believe that it is (almost) October already. The images of the week will be featuring more of the oranges, yellows, and reds of autumn. One of the images that I had to cut for lack of time is a pumpkin patch in Potomac, Maryland. There will, however, be plenty of pumpkin photos available for the shows later in October.

These pumpkins were left on the cutting room floor ...

A video of last weekend's Shortwave Radiogram (program 223, Saturday 1330 UTC) is provided by Scott in Ontario. Also, from that same transmission, an excerpt of reception by Mark in the UK countryside.  And an excerpt of decoding the Sunday 2330 UTC show by OfficialSWLchannel.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 224, 30 September-3 October 2021, in MFSK modes as noted:

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!
