Shortwave Radiogram, 15-18 August 2019

Shortwave Radiogram

Many thanks to Mike Agner, KA1JJZ, @MakeAgner, who has prepared two very
good wikis on how to decode the modes on Shortwave Radiogram.

This one deals with decoding on PCs …

And this is for users of TIVAR on Android devices …

As always, wikis are works in progress, so if you have suggestions for additional information, please let us know

The only mishap in last weekend’s Shortwave Radiogram was that the
transmission scheduled for UTC Saturday 0230-0300 on 9265 kHz from WINB
was 15 minutes early, thus 0215-0245. Fortunately, many of you had tuned
in early (always a good idea) and were able to decode the entire show.
WINB is aware of the problem, so I hope they are back on regular time
this weekend.

Videos of last weekend’s Shortwave Radiogram (program 112)  are provided by Scott in Ontario (Friday 1300 UTC), Marco in Italy and Ralf in Germany (both Sunday 2330-2400 UTC).  The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend, there will be another “hidden message,” although
this time I will provide the parameters in advance. After the end of
the final MFSK32 at 29:03, PSK125R will begin at 29:15. It will be
centered on 63 Hz, thus mostly inaudible. And to make it even more
interesting, I reduced the level to 12 dB under the closing music. There
is an RSID, but it probably won’t work, so be ready to change the mode
and audio frequency manually. Let’s see if it can survive shortwave.

This weekend’s show is in the usual MFSK32 and MFSK64, with nine MFSK64 images.

Here is the lineup for Shortwave Radiogram, program 113, 15-18 August 2019, in MFSK modes as noted:

1:40  MFSK32: Program preview
2:51  Decline in freshwater megafauna population
6:55  MFSK64: Comet 67P/C-G had a tiny, temporary moon*
10:39  Steam-propelled CubeSats control one another in space*
15:12  This week’s images*
28:14  MFSK32: Closing announcements

* with image(s)

The Mighty KBC transmits to North America Sundays at 0000-0200
UTC (Saturday 8-10 pm EDT) on 9925 kHz, via Germany. A minute of MFSK is
at about 0130 UTC.  Reports to Eric: . See also and

“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 Thursday 0100-0200 UTC (Wednesday evening in
the Americas) on 5850 kHz, and Thursday 0130-0230 UTC (Wednesday
evening in the Americas) on 9395 kHz, both frequencies via WRMI
Florida.  Also look for a waterfall ID at the beginning of the show. .

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 1200 UTC on 3583 kHz USB (with
out-of-state check-ins now starting at 1130 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, Wednesdays at 2300 UTC (7 pm EDT)
on 3536 kHz USB. I will try to check in to this net more frequently.


Energy Alchemist @EnergyA1 in California received these images UTC 10
August, 0215-0245 UTC (transmitted 15 minutes early), on 9265 kHz from
WINB Pennsylvania …
