Shortwave Radiogram, 19-22 March 2020: A good socially distant activity

Shortwave Radiogram

During this extraordinary time when COVID-19 is still in its ascendancy most places, I hope you are staying healthy. Shortwave Radiogram is a good activity during enforced isolation. And we can stay distantly social by way of email and the Twitter and Facebook accounts listed below.

Spring propagation is bring good signals at some times, on some frequencies, in some parts of the world. Elsewhere, reception has deteriorated. Such is shortwave. It appears that reception in Japan of our Sunday 0800 UTC broadcast has mostly ended until the next winter approaches. Reception in Europe of that broadcast continues, to my
surprise, but that won’t last much longer as mornings become more filled with daylight.

Videos of last weekend’s Shortwave Radiogram (program 143) are provided by Lolo sdr in Spain (Friday 1300 UTC),  i0kte Stefano in Italy (Saturday 1330), radio no koe in Japan (excerpt showing difficult reception) and Scott in Ontario (both Sunday 0800 UTC on 5850 kHz), and Jeff in Oklahoma (Sunday 2330 UTC).  The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

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

Here is the lineup for Shortwave Radiogram, program 144, 19-22 May 2020, in MFSK modes as noted:

1:46  MFSK32: Program preview
2:55  Russian plans first spacecraft to Moon in 45 years*

The Mighty KBC transmits to North America Sundays at

“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 0200-0300 UTC on 5850
kHz (Wednesday evening in the Americas) and a new time also on WRMI,
Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) . 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. 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.

Marco in Italy received these images 14 March 2020, 1330-1400 UTC, on 15770 kHz from WRMI Florida …
