Shortwave Radiogram, 21-24 November 2019

Shortwave Radiogram

Thanks to those you who participated in last weekend’s test of the low-but-robust modes Olivia 32-2000 and MFSk16. There were some examples (see this example) of those two modes providing good decodes when the faster MFSK32 and MFSK64 showed errors.

Videos of last weekend’s Shortwave Radiogram (program 126) are provided by Scott in Ontario (Friday 1300 UTC), 2010DFS in Japan (Sunday 0800 UTC on 5850 kHz), and Jeff-W5IJH in Oklahoma (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

With the internet shutdown in Iran is in the news, this weekend Shortwave Radiogram will transmit an excerpt of Persian text, from a Deutsche Welle Persian news article about waste  created by food packaging in Germany. You will need the UTF-8 character set for the Persian, but these are the default in  Fldigi and TIVAR.

This weekend’s show is in the usual MFSK32 and MFSK64   .

Here is the lineup for Shortwave Radiogram, program 127,  21-24 November 2019, in MFSK modes as noted:

1:38  MFSK32: Program preview
2:53  U.S. to help Iranians bypass internet shutdown
5:48  MFSK64: How US/EU could facilitate free Iran internet*
11:56  Example of Persian-language text**
14:41  This week’s images*
27:53  MFSK32: Closing announcements

“This is a Music Show” is the newest addition to
digital modes via analog shortwave. 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 0100-0200 UTC on 5850
kHz and 0130-0230 UTC on 9395 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 1300 UTC on 3584 kHz USB, and the
Pennsylvania NBEMS net Sunday at 1300 UTC on 3583 kHz USB (with
out-of-state check-ins now starting at 1230 UTC). Check-ins are usually
in Thor 22, and messages are in MFSK32 (PA NBEMS is experimenting with
Thor 50×1 for messages). 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, Thursdays at 0000 UTC (Wednesday 7 pm EST) on 3536 kHz USB.


Lama-Bleu in French Guiana used an SDR near Paris to decode the
Olivia 32-2000 and MFSK16, 17 November 2019, 0800-0830 UTC, 5850 kHz
from WRMI Florida. It is only during the winter months that this
transmission is receivable in Europe.
