Shortwave Radiogram, 15-17 March 2019

Shortwave Radiogram

Last weekend’s moving forward of the clocks in most of North America
brings about some changes in Shortwave Radiogram broadcast times
effective today and tomorrow. The WINB DRM transmitter on 13755 stays
with UTC, so the Friday 1500 UTC DRM broadcast is one hour later by
local time in North America. On the other hand, the WINB analog
transmitter on 9265 kHz stays with local time in Pennsylvania. So
Shortwave Radiogram remains at 10:30 pm Friday Eastern time but changes
to 0230 UTC (Saturday). The WRMI transmitters used by Shortwave
Radiogram stay with UTC, so the show will be heard one hour later by
local time in North America, starting today at 4:30 pm EDT (2030 UTC) on
7780 kHz. Space Line Bulgaria also stays with UTC. See the schedule

Videos of last weekend’s Shortwave Radiogram (program 90) are provided by Scott in Ontario (Friday 2030 UTC) and Ralf in Germany (Saturday 1400 UTC). “COMMS Partisan” in Ohio produced this video showing how he uses an antenna tuner and analyzer to optimize his reception of 7780 khz, and this video of his actual reception (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Shortwave Radiogram this weekend is in the usual MFSK32 and MFSK64, with
ten images, most colorful, one with interesting black-and-white shapes.

Here is the lineup for Shortwave Radiogram, program 91, 15-17 March 2019, in MFSK modes as noted:

Slow Scan Radio transmits SSTV images and text modes
Saturdays at 1300-1330 UTC on 6070 kHz and 7440 kHz via Channel 292 in

“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). 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 (8 am EDT) on 3584 kHz USB,
and the Pennsylvania NBEMS net Sunday at 1200 UTC (8 am EDT,
out-of-state check-ins starting at 7:30 am) on 3583 kHz USB. Check-ins
are in Thor 22, and messages are in MFSK32. 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.



Mark in the UK received these images 10 March at 2330-2400 UTC on 7780 kHz from WRMI Florida …


For that same Sunday 2330 UTC transmission, Zach in Alabama wrote:
“Would you believe that virtually 100% of the text came through, despite
these @SWRadiogram images looking so ragged? And only one missed pic trigger that I had to go back and re-try. Amazing” …
