Shortwave Radiogram, 19-22 September 2019

Shortwave Radiogram

Last weekend’s “hidden message” in BPSK63F at 70 Hz was fairly successful. Several listeners reported successful decodes. It looks like 70 Hz will be our standard frequency for text that is mostly inaudible
but usually decodable. There will be no hidden message this weekend, but we will resume these experiments later this year.

A video of last weekend’s Shortwave Radiogram (program 117)), Friday 1300 UTC, is provided by Scott in Ontario (you can decode the BPSK63F and other modes from the audio). 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 images.

Here is the lineup for Shortwave Radiogram, program 118, 19-22 September 2019, in MFSK modes as noted:

1:39  MFSK32: Program preview
2:44  Synthetic Hall Effect achieves one-way radio transmission
9:12  MFSK64: Volcano may explain recent purple sunrises*
15:01  This week’s images*
27:27  MFSK32: Closing announcements*

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: themightykbc@gmail.com . See also http://www.kbcradio.eu/ and https://www.facebook.com/TheMightyKbc/.

“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 0100-0200 UTC on 5850
kHz and 0130-0230 UTC on 9395 kHz (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 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 at 2300 UTC (7 pm EDT)
on 3536 kHz USB. I will try to check in to this net more
frequently.

Frank in Perth, Western Australia, received these images (and 100% text)
15 September 2019, 0800-0830 UTC, 7730 kHz from WRMI Florida (18400
km!) …
