Shortwave Radiogram,12-14 April 2019

Shortwave Radiogram

Last week was a difficult week for Shortwave Radiogram. The transmission
from Bulgaria on 9400 kHz Saturday at 1400 UTC was canceled too late for me to
notify you in the weekly email. It is uncertain whether a Shortwave
Radiogram broadcast from Bulgaria will be restored. I am exploring other
transmission possibilities. For now, best reception in Europe is
probably Saturday at 0230 UTC on 9265 kHz and Sunday at 2330 UTC on 7780
kHz. These are both inconvenient hours for European listeners. Some
listeners leave their radios and Fldigi on all night and see the results
in the morning. The Audacity timer record feature can also be useful.

Also last weekend, Sunday at 0800 UTC, 5850 kHz was not heard from WRMI
because of a transmitter issue. However, parallel 7730 kHz was on the
air. Both frequencies should be available this weekend.

Please note the new frequency of 15120 kHz for the WINB DRM transmission Fridays at 1500-1530 UTC.

Videos of last weekend’s Shortwave Radiogram (program 94) are provided by Scott in Ontario (Friday 2030 UTC) and Ralf in Germany (Sunday 2330 UTC, using MultiPSK). COMMS Partisan in Ohio has a video of the WWV story from Sunday 2330 UTC. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Transmissions to listen for: The International Space
Station is transmitting SSTV (PD120) again this weekend until Sunday at
1800 UTC on 145.8 MHz FM. See this press release.
And another art project involving SSTV is under way. This time artist
Lucy Helton is transmitting SSTV (Martin 2) from Iceland on 14227, or
thereabouts, in the 20 meter amateur band. The project continues through
23 April. Information at

Slow Scan Radio transmits SSTV images and text modes

“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 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.
