Shortwave Radiogram, 22-24 February 2019

Shortwave Radiogram

Last call for the Winter SWL Fest, 28 February to 2 March in Plymouth Meeting, Pennsylvania (near Philadelphia). I will be there, weather permitting.

And see information below about “This is a Music Show,” on WRMI, which
includes some MFSK. Also, some changes to the PANBEMS Net.

WINB’s DRM transmitter was not on the air last weekend: apologies if you
tried to tune in. And WINB has a new frequency for its DRM transmitter:
13755 kHz. Shortwave Radiogram will be today (Friday) at 1500-1530 UTC
on 13755. You can use KiwiSDR receivers in conjunction with the Dream
software to decode DRM. See this post from the website for instructions.

Last weekend we another example of an amazingly successful decode of
Olivia 64-2000 text under adverse conditions. You can see/hear/decode
that Olivia 64-2000 here.

Videos of last weekend’s Shortwave Radiogram (program 87) are provided by Scott in Ontario (Friday 2030 UTC), Ralf in Germany (Saturday 1400 UTC), Martín In Mexico (Sunday 0800 UTC 7730 kHz), and “youngalientype” (Sunday 2330 UTC, Olivia 64-2000 segment). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 88, 22-24 February 2019, in MFSK modes as noted:

“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, 5850 kHz, Thursday
0100-0200 UTC (Wednesday evening in the Americas). The first show this
past Wednesday had MFSK64 text and an MFSK32 image. You might have to
set the mode manually. Also look for a waterfall ID at the beginning of
the show.

Slow Scan Radio transmits SSTV images and text modes
Saturdays at 1300-1330 UTC on 6070 kHz and 7440 kHz via Channel 292 in
Germany – according to the latest schedule information I have. The
website is Reception reports to

The Mighty KBC transmits to Europe Saturdays at
1300-1400 UTC on 11600 kHz from Bulgaria, with the minute of MFSK at
about 1330 UTC (if you are outside of Europe, listen via ). And to North America Sundays at 0000-0200
UTC (Saturday 7-9 pm EST) on 5960 kHz, via Germany. The minute of MFSK is at about 0130 UTC.  Reports to Eric: . See also and

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 new 1230 UTC for out-of-state stations
(1300Z for stations in Pennsylvania)  on 3583 kHz USB. Check-ins are in
Thor 22, and messages are in MFSK32, although PANBEMS is experimenting with Thor50x1 for traffic. Messages usually 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.


Zach in Alabama received these MFSK images made artistic by shortwave reception in the skip zone for 7780 kHz …
