Shortwave Radiogram, 13-16  de Junio 2019

Shortwave Radiogram

This weekend our modes will again be MFSK32 and MFSK64. These modes work very
well in shortwave broadcast conditions, with MFSK32 more successful,
although slower, if reception is somewhat difficult. Now we need a
simple, receive-only, decode-only software for PCs, and app for mobile
devices, that decode MFSK 16, 32, 64, and 128 …

MFSK16 (55 wpm) for difficult conditions
MFSK32 (120 wpm) for fair conditions
MFSK64 (240 wpm) for good conditions
MFSK128 (480 wpm) for excellent conditions (e.g. local FM or medium wave)

The software should be able to decode, and optionally save, both text
and images.  An RxID would detect which flavor of MFSK is being
transmitted and the center audio frequency.

Everything went smoothly last weekend except that the first broadcast of
the weekend, Thursday at 2330 UTC, was the previous week’s show. This
was because of a problem with the automated playout system at WINB.

Videos of last weekend’s Shortwave Radiogram (program 103)  are provided by Scott in Ontario (Friday 1300 UTC) and Ralf in Germany (Sunday 2330 UTC). Jeff, W5IJH, in Oklahoma also provides a video of his first decode of Shortwave Radiogram (Sunday 2330 UTC). Tengu in Japan
produced this video of his decode of a previous Shortwave Radiogram,
using one of Ralf’s videos. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

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

Here is the lineup for Shortwave Radiogram, program 104, 13-16 June 2019, in MFSK modes as noted:

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 on WRMI, 9395 kHz, Thursday 0130-0230 UTC
(Wednesday evening in the Americas). 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.



Radio-no-koe in Japan received these images during the 0800 UTC broadcast using an SDR in Hawaii …
