Shortwave Radiogram, 19-21 April 2019

Shortwave Radiogram

Too late for last weekend’s email, I was informed that the Friday
2030-2100 UTC broadcast of Shortwave Radiogram was replaced in the WRMI
by a religious program. WRMI has provided this replacement time slot:
Friday at 1300-1330 UTC on 15770 kHz. This is directed to Europe. See
the new transmission schedule below.

I am still exploring opportunities for a transmitter closer to Europe.
In the meantime, the Sunday 2330-2400 UTC broadcast on 7780 kHz from
WRMI has lately been heard and decoded well in Europe, Unfortunately,
the hour is not convenient for most Europeans. Some listeners in Europe
try “unattended reception”: radio and Fldigi, or radio and recorder,
running all night. Audacity’s timer record feature can also be helpful.

The Saturday 0230-0300 UTC transmission from WINB is also often received
in Europe. Due to the peculiarities of WINB’s audio, the RSIDs often do
not change Fldigi’s mode. One solution would be to use a recorder, then
manually change modes when decoding from the recording.

Videos of last weekend’s Shortwave Radiogram (program  95) are provided by 2010DFS in Japan (Sunday 0800 on 7730 kHz, received in Japan and decoded despite co-channel interference), Ralf in Germany and Scott in Ontario (both Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Because of reception in Japan this spring during the 0800 UTC broadcast,
this weekend we will transmit some Japanese text in MFSK32.

Here is the lineup for Shortwave Radiogram, program 96, 19-21 April 2019, in MFSK modes as noted:

The Mighty KBC transmits to North America Sundays at 0000-0200 UTC (Saturday 8-10 pm EDT) on 5960 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, 5850 kHz, Thursday 0100-0200 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.

Mark in the UK received these images 14 April 2019, 2330-2400 UTC, 7780 kHz from WRMI Florida …
