Last week we enjoyed good reception – or at least good enough for MFSK32 – most of the time and in most places where our signal could reasonably be heard. Thanks for noting, in your reception reports, the approximate percentage of text that decoded correctly. Our images are fun, but it is the text that is really important as a communication tool. Each week, our basic goal is that our most robust text mode
decodes at least 90 percent.
Videos of last weekend’s Shortwave Radiogram (program 152) are provided by Scott in Ontario (Friday 1300 UTC) and Ralf in Germany (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
On this weekend’s show, our “special guest mode” is Thor22 (Or is is
supposed to be THOR? If so, why all capital letters?). Thor22 is the
mode that the New York and Pennsylvania NBEMS nets use for check-ins,
partly because it has a reasonable typing speed: 78 wpm. There is also
the usual MFSK32 and MFSK64, with eleven MFSK64 images.
Here is the lineup for Shortwave Radiogram, program 153, 21-24 May 2020, in modes as noted:
1:49 MFSK32: Program preview
2:59 Thor22: Wireless Power Transfer proposal and HF
5:50 MFSK64: Stamp marks 100 years of radio in Canada*
9:21 Asparagus craze in Germany during the coronavirus crisis*

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. 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 email@example.com , 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 2300 UTC (7 pm EDT) on 3536 kHz USB.
On 14 May 2020, 2330-2400 UTC, the fuzzy images received by
@K7al_L3afta in Morocco indicated challenging reception from WINB on 9265 kHz. But his decode of the MFSK32 text was 100%!
