Shortwave Radiogram, 4-6 December 2020

Hello friends,

Because of  increased solar activity, and because of conditions generally during these months near the solstice, reception and decoding will be interesting in the next few weeks. For example, the 15770 kHz transmissions, directed to Europe, might be audible in New Zealand.  And last week, the Friday 0030 UTC broadcast, 9265 kHz from WINB, produced good images in Hawaii.

The Sunday 0800-0830 UTC show, beamed to Asia-Pacific, can often be heard in Europe this time of year.  However, because of the STANAG 4285 on 5850 kHz, I might add another mode at 2200 Hz to sidestep the data noise. In Europe, listen/look for that at 0828 UTC.  It worked last week.

A video of last weekend’s Shortwave Radiogram (program 180) is provided Scott in Ontario (Saturday 1300 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 ten images (1 x MFSK32 and 9 x MFSK64).

Here is the lineup for Shortwave Radiogram, program 181,  4-6 December 2020, in MFSK modes as noted:

 1:42  MFSK32: Program preview
 2:45  Arecibo Radio Observatory collapses*
 8:45  MFSK64: Electronic waste on the decline, study finds
12:34  This week’s images*
28:25  MFSK32: Closing announcements

“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, 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. thisisamusicshow@gmail.com @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.
Thanks for your reception reports!
