Shortwave Radiogram, 1-4 August 2019

Shortwave Radiogram

There were not very many responses last week to my question about whether you prefer “natural” line wrapping versus the CR/LF that I usually put at column 65 (or less). But the answers I did get favored
the line breaks at 65. We will try it again this weekend: Natural wrapping in the MFSK32 news item (Ethiopia trees), and the line breaks in the MFSK64 news items.

Last weekend’s mishaps included the previous weekend’s show Friday at
1300-1330 UTC – because i forgot to uplink the latest show to WRMI.
That was corrected in time for the Sunday shows on WRMI. And Sunday at
0800 UTC, 5850 kHz did not come on the air. This was because of a feed
line problem that could not be fixed until daylight. The good news was
that 7730 khz was on the air and provided good reception in North America and the Pacific region.

Videos of last weekend’s Shortwave Radiogram (program 110 except where noted) are provided by Randy in Michigan (Thursday 2330 UTC excerpt), Scott in Ontario (Thursday 1300 UTC, program 109 because I forgot to upload 110 in time), Ralf in Germany (Sunday 2330 UTC), and COMMS Partisan in Ohio (Sunday 2330 UTC excerpt). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany (where you can see the difference between the natural line breaks versus the CR/LF at 65 columns).

This weekend’s show is in the usual MFSK32 and MFSK64, with ten MFSK images.

Here is the lineup for Shortwave Radiogram, program 111, 1-4 August 2019, in MFSK modes as noted:

“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, Thursdays 0100-0200 UTC,
and 9395 kHz, Thursdays 0130-0230 UTC (overlapping broadcasts 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. USEast NBEMS Net:
Please also note the USEast NBEMS Net, Wednesdays at 2300 UTC (7 pm EDT)
on 3536 kHz USB. I will try to check in to this net more frequently.

. MFSK pics were about P3 quality with some fade in the pics. Here is my first attempt at using GIMP to combine the images on a single canvas…still lots to learn.” …
