Shortwave Radiogram, 5-8 September 2019

Shortwave Radiogram

We are happy to know that WRMI in Okeechobee, Florida, was spared a
direct hit by Hurricane Dorian. The Shortwave Radiogram schedule should,
therefore, proceed as normal. WRMI was not entirely unscathed, having
experienced some internet disruptions. Good luck to those still in the
path of Dorian.

Last week’s hidden message exercise, with BPSK63F at 95, 85, 75 and 65
Hz, was fun. Most of us had trouble with the 65 Hz message, but there
were a few perfect decodes of all four.

Videos of last weekend’s Shortwave Radiogram (program 115) are provided by Scott in Ontario (Friday 1300 UTC) (You can try to decode the hidden message from his video) and by MD2 in Colorado (excerpt of Sunday 0800 UTC on 5850 kHz; the audio sounds like unrelated FT8).  The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend’s hidden message will be in Thor Micro at
70 Hz. There is no RSID for Thor Micro, so be prepared to change the
mode and audio frequency manually as soon as the final MFSK32 ends. Thor
Micro is a very slow mode. You will not see text until a few seconds
after you see the Thor Micro trace down at 70 Hz.

This weekend’s show is in the usual MFSK32 and MFSK64 with nine images, plus the Thor Micro.

Here is the lineup for Shortwave Radiogram, program 116, 5-9 September 2019, in modes as noted:

1:40  MFSK32: Program preview
2:48  Undersea sensor powered by sound waves from the surface
6:27  MFSK64: Will EVs disrupt Germany’s power grid?*
11:23  This week’s images*
25:42  MFSK32: Closing announcements
27:15  Thor Micro: Hidden message centered on 70 Hz

The Mighty KBC transmits to North America Sundays at 0000-0200 UTC (Saturday 8-10 pm EDT) on new 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 Thursday at 0100-0200 on 5850 kHz and
0130-0230 on 9395 kHz (Wednesday evening in the Americas), both from
WRMI Florida. 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.

 

 

Three images get the shortwave artistic treatment. From the show 1
September. 2330-2400 UTC, 7780 kHz from WRMI Florida, as decoded by Al
in the northern Florida skip zone.
