Hello friends,
Last week's experiment with MFSK16 produced some successful decodes when the MFSK32 and MFSK64 text was less than 100%. I had a couple examples on 15770 kHz from WRMI Florida using SDRs in Russia and Ukraine. For some reason, my decodes of the MFSK16 from WINB on 9265 kHz were largely unsuccessful, even though the MFSK32 and MFSK64 text decoded correctly. WINB audio is a bit strange.
We also had fun with the retro black-and-white test pattern, transmitted in MFSK16, 32, and 64, to compare resolutions of the decoded images. Thanks for the results submitted to the @SWRadiogram Twitter and via email.
Videos of last weekend's Shortwave Radiogram (program 171) are provided by Scott in Ontario (Friday 1300 UTC) and Frigid RF in Virginia (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 eleven images, all MFSK64.
Here is the lineup for Shortwave Radiogram, program 172, 1-4 October 2020, in MFSK modes as noted:

“This is a Music Show” 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) .

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 radiogram@verizon.net , 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.
Thanks for your reception reports!
