Shortwave Radiogram, 14-16 February 2020

Shortwave Radiogram

Today (February 13) is UNESCO’s World Radio Day. The day is not so much for radio enthusiasts, but to promote the social goals of UNESCO by way of radio. Nevertheless, it’s good to have a day that acknowledges radio.
So Happy Radio Day!

Another celebration of radio is the annual Winter SWL Fest, this year February 27-28-29 at Plymouth Meeting, Pennsylvania. The sessions and activities are very interesting. I will be speaking after the banquet on
“International Broadcasting in Interesting Times.” I hope you can attend. Information at http://swlfest.com.

We enjoyed mostly good reception last week, and successful text decodes even when reception was not brilliant. Videos of last weekend’s Shortwave Radiogram (program 138) are provided by Scott in Ontario (Friday 1300 UTC), 2010DFS in Japan (Sunday 0800 UTC on 7730 kHz – mostly successful text decode despite the distance and a co-channel voice broadcast!), and Lolo sdr in Spain (Sunday 2330 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 eight MFSK images.

Here is the lineup for Shortwave Radiogram, program 139, UTC 14-16 February 2020, in MFSK modes as noted:

1:46  MFSK32: Program preview
2:56  Voyager 2 back online after power supply issue

The Mighty KBC transmits to North America Sundays at
0000-0200 UTC (Saturday 7-9 EST) 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 0200-0300 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 1300 UTC on 3584 kHz USB, and the
Pennsylvania NBEMS net Sunday at 1300 UTC on 3583 kHz USB (with
out-of-state check-ins now starting at 1230 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, Thursdays 0000 UTC (Wednesdays 7 pm EST) on 3536 kHz USB.

@jushin_Perseus in Japan received and decoded these images, 9
February 2020, 0800-0830 UTC on 7730 kHz. These images decodes are
amazing given the distance from Florida to Japan, and given the presence
of voice broadcast on the same frequency. See his video.
Propagation from Florida to Japan at this time and on this frequency
will no longer be available in the next few weeks, as the northern
hemisphere nights become shorter.
