Shortwave Radiogram, Saturday-Sunday schedule


Hello friends,

In last week's email, I forgot to note the new "winter" frequency of The Mighty KBC, now on 5960 kHz from a transmitter in Germany, Sundays 0000-0200 UTC (Saturday 8 to 10 pm EDT). In addition to the great mix of oldies hits, there is a minute of MFSK64 at 0130 UTC.

A video of last weekend's Shortwave Radiogram (program 220, Friday 1300 UTC) is provided by Scott in Ontario. The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.

On this weekend's program (221), we will resume our experiment, suggested by Tobias in Germany, of eliminating the gap (about 0.7 seconds) between the text introduction of an image and the image itself. Perhaps there will be fewer lost image headers when that gap is removed. So far, our results have been inconclusive, but we will try again. Of the nine images in the show, there will be no gap in front of Big Ben, Ithaca, and Stromness.

Here is the lineup for Shortwave Radiogram, program 221, 9-12 September 2021, in MFSK modes as noted:

 1:42  MFSK32: Program preview
 2:46  Medical journals warn about climate change
 7:24  MFSK64: Satellite test signals in the Q and W bands*
12:31  This week's images*
28:00  MFSK32: Closing announcements
* with image(s)

“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!
