Shortwave Radiogram, UTC 6-8 March 2020: Digital modes that dock in orbit

Shortwave Radiogram

Thanks to Al @WD4AH for moderating the @SWRadiogram Twitter account while I was attending the Winter SWL Fest in Plymouth Meeting, Pennsylvania. The @SWRadiogram Twitter is the best way to see the decoding results of Shortwave Radiogram listeners around the world. If you don’t have a Twitter account, go to   and scroll down.

I was not able to tune in most of the Fest weekend, which may have been just as well, because there were some mishaps. The WRMI 15770 kHz transmitter was not on the air Saturday at 1330 UTC. The WRMI 5850 and
7730 kHz transmitters were on the air Sunday at 0800 UTC, but Brother Stair kept on preaching instead of the scheduled Shortwave Radiogram. I hope these issues are resolved by this weekend.

This weekend most of North America returns to Daylight Savings Time,Sunday at 2:00 am local. Shortwave Radiogram remains at its UTC times on WRMI, so in most US states, Shortwave Radiogram will be one hour later
by local time Sunday at 0800 and 2330 UTC. There will be additional time changes next weekend.

Videos of last weekend’s Shortwave Radiogram (program 141) are provided by Lola sdr in Spain Saturday 0330 and Sunday 2330 UTC, and by Scott in Ontario, 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 ten MFSK images.

Here is the lineup for Shortwave Radiogram, program 142, UTC 6-8 March 2020, in MFSK modes as noted:

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: . See also and

“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 (Wednesday evening in the Americas) and a new time also on WRMI,
Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) . 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 , 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.


Georgi in Bulgaria received these images 28 February, 1300-1330 UTC,
15770 kHz from WRMI Florida (9055 km) using a Sony ICF-SW12 pocket
radio with its telescopic whip antenna. MFSK32 and MFSK64 text decoded
