Hello friends,
During the past two weekends, we saw a few examples of the new MFSK wide modes providing an improvement over the conventional MFSK32 and MFSK64. While the tests were mostly inconclusive, we did learn about the performance of the wide modes based on your reports (thank you!). John KL4YFD is using this information to work on different versions of the wide modes. We might be able to try these in future broadcasts.
Videos of last weekend's Shortwave Radiogram (program 177) are provided by Scott in Ontario (Saturday 1330) and Jeff in Oklahoma (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.
No experiments this weekend. We will return to our usual format consisting entirely of MFSK32 and MFSK64 text, with eight MFSK64 images.
Here is the lineup for Shortwave Radiogram, program 178, 13-15 November 2020, in MFSK modes as noted:
1:39 MFSK32: Program preview
2:43 Hurricanes lingering longer after landfall
5:58 MFSK64: Science's top 10 erroneous results
14:24 This week's images*
28:34 MFSK32: Closing announcements
* with image(s)

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 1230 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, Thursdays 0000 UTC (Wednesdays 7 pm EST) on 3536 kHz USB.
Thanks for your reception reports!
Kim Andrew Elliott, KD9XB
