Shortwave Radiogram, 29-31 January 2021

The word “blustery” was created for days like we are having today in the Washington DC area. It’s below freezing with gusts that sahke the house. At least my wire antennas are still in the air. And I hope electricity is not interrupted until I finish this email. They say we might get some snow on Sunday, which would be scenic break from our extended snow drought.

Videos of last weekend’s Shortwave Radiogram (program 188) are provided by Francisco in Brazil (excerpt of TIVAR reception, Friday 0330 UTC) and by Scott in Ontario (Saturday 0330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany. Also see Roger’s explanation of the interesting images created by my multipath reception last weekend via an SDR in New Zealand (47 ms difference between the short path and long path).

This weekend we will add a brief segment of Olivia 32-2000 to our usual MFSK32 and MFSK64. The Olivia 32-2000 might survive adverse conditions such as the OTH radar interference I have been hearing lately via SDRs in Japan (Sunday 0800 UTC on 5850 kHz). Hint: Do not use the Fldigi squelch (SQL) during Olivia 32-2000 reception. The show will also include eight MFSK64 images.

Here is the lineup for Shortwave Radiogram, program 189,  29-31 January 2021, in modes as noted:

  1:46  MFSK32: Program preview
  2:53  Laser link could test of Einstein’s theory

“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) . Also look for a waterfall ID at the beginning of the show. . @ThisIsAMusicSho

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 , 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.
