Shortwave Radiogram, 12-15 September 2019

Shortwave Radiogram

Today I had difficulties uploading Shortwave Radiogram to WINB. We will find out at  2330 UTC if the correct program (number 117) is transmitted.

Last weekend’s hidden message in Thor Micro at 70 Hz was mostly successful. This weekend, it was my intention to try Throb 1, another very narrow mode, also at 70 Hz, but I could not get a decode from the
recording. It seems that Throb 1 does not like the very low audio frequencies. Our hidden message will be in BPSK63F instead, at a center audio frequency of 70 Hz.

A video of last weekend’s Shortwave Radiogram (program 116)  is provided by Scott in Ontario
(Friday 1300 UTC) (and it is a good example of mostly successful decoding in challenging conditions). 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. Also the BPSK63F hidden message.

Here is the lineup for Shortwave Radiogram, program 117, 12-15 September 2019, in modes as noted:

1:38  MFSK32: Program preview
2:46  CPJ’s list of 10 most censored countries*

“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, Thursday, 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. . or @ThisIsAMusicSho

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 , 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.
