For some of the Shortwave Radiogram transmissions last weekend,propagation was difficult. On other transmissions, reception was great. We can declare success if 90% of the MFSK32 text decodes correctly. That will often happen even under very difficult reception conditions.

Videos of last weekend’s Shortwave Radiogram (program 150) are provided by Scott in Ontario (Friday 1300 UTC), UR1002 SWL in California (Sunday 0800 UTC 7730 kHz, segments decoded vy TIVAR), and Ralf in Germany (Sunday 2330-2400 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 nine MFSK64 images.

Here is the lineup for Shortwave Radiogram, program 151, 7-10 May 2020, in MFSK modes as noted:

1:42  MFSK32: Program preview
2:48  Asteroid’s close encounter with a geosynchronous satellite
7:17  MFSK64: Antarctica and Greenland’s shrinking ice sheets*
14:04  This week’s images*
28:17  MFSK32: Closing announcements

* with image(s)

The Mighty KBC transmits to North America Sundays at
0000-0200 UTC (Saturday 8-10 EDT) on 9925 kHz, via Germany. (Reception
on this summer frequency was difficult last weekend. Let’s hope it
improves this weekend. If not, the audio stream is at
https://www.kbcradio.eu/ .) A minute of MFSK is at about 0130 UTC.

“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 radiogram@verizon.net , 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.
