Shortwave Radiogram, 20-23 August 2020: Digital modes that will dent your magnetic shield

 

Last weekend’s experiment with Belarusian text from RFE/RL was generally
successful. It was also timely, given the interdiction of the internet
in Belarus. This tweet
showing distant reception of the Belarusian text using simple equipment
generated much interest.  For now, the text is decoded using software
and apps designed for the amateur radio community. We need simpler
software and apps so that news consumers can use shortwave (and medium
wave and longwave) to receive text when the internet is restricted or
otherwise not available.

Videos of last weekend’s Shortwave Radiogram (program 165) are provided by Scott in Ontario (Friday 1300 UTC) and Frigid RF in Virginia (Saturday 1330 UTC).  The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend, no exotic modes or non-Latin alphabets. We will return to
those experiments in the future and welcome your suggestions. This
weekend’s show is in the usual MFSK32 and MFSK64, with eleven images (1 x
MFSK32 and 10 x MFSK64) .

Here is the lineup for Shortwave Radiogram, program 166, 20-23 August 2020, in MFSK modes as noted:

1:43  MFSK32: Program preview
2:46  Scientists monitor changes in magnetic field*
7:55  MFSK64: Review of new film biopic Tesla*

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.
