Shortwave Radiogram, 24-26 January 2020: Hottest recorded digital modes

Shortwave Radiogram

The Shortwave Radiogram transmission schedule included with the weekly email last week contained errors. Thanks to those of you who let me know, especially Marco in Italy, who found all the errors – some involving frequencies, some involving transmitter sites. The transmission schedule below should be correct. I hope.

Last weekend, reception conditions were generally good. However,  we had a scare just before the Sunday 2330 UTC broadcast. The audio quality was very poor (although I wonder if the MFSK32 might have been decoded anyway). A quick email to WRMI brought a quick response.

They turned off one of their audio processors (not the main Optomod processor) and the audio quickly improved. Audio issues at WRMI have continued, intermittently, since last weekend, so let’s hope for the best during this weekend’s Shortwave Radiogram transmissions.

Videos of last weekend’s Shortwave Radiogram (program 135) are provided by Scott in Ontario (Saturday 1330 UTC)  and  by Ralf in Germany and Jeff in Oklahoma (both 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 136, UTC 24-26 January 2020, in MFSK modes as noted:

1:44  MFSK32: Program preview
2:54  Last decade was hottest recorded
5:30  MFSK64: First asteroid closer to Sun than Venus found*
8:20  History of the KPH maritime radio station in California*
13:56  This week’s images*
28:31  MFSK32: Closing announcements

“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 0100-0200 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. . @ThisIsAMusicSho

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.


Frank in Perth, Western Australia, using an SDR in Texas, received
these images 17 January 2020, 0030-0100 UTC, on 9265 kHz from WINB
Pennsylvania …
