A prospective Shortwave Radiogram listener sent an email asking about the basic
equipment needed to receive and decode the modes. This reminded me of the need
to revisit the How to Decode the Modes of the Shortwave Radiogram
It would seem all that is needed is a radio and a computer, with
a patch cord from the earphone jack of the radio to the microphone jack of the
computer. But, nowadays, many computers don't have separate mic jacks. And if
a patchcord is plugged into a radio's earphone jack, the speaker is muted. These
are just two of the problems that can occur in the decoding chain. So, with
your help, I will try to develop new "how to" document.
This weekend's show is
in the usual MFSK32 and MFSK64, with nine images.
Here is the
lineup for Shortwave Radiogram, program 105, 20-23 May 2019, in MFSK
modes as noted:
MFSK32: Program preview 2:51 The ghost galaxy that hit the Milky Way long
ago* 7:51 MFSK64: Europe's plastics problem* 12:08 Five ways a 'lazy'
lawn makes pollinators happy* 16:59 This week's images* 28:33 MFSK32:
* with image(s)

The Mighty KBC
transmits to North America Sundays at 0000-0200 UTC (Saturday 8-10 pm
EDT) on 9925 kHz, via Germany. A minute of MFSK is at about 0130 UTC.

“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, 9395 kHz,
Thursday 0130-0230 UTC (Wednesday evening in the Americas). Also look for a
waterfall ID at the beginning of the show. email@example.com .
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 50x1 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 firstname.lastname@example.org , or tweet to @SWRadiogram , and
I will let them know you are tuned in.
