Shortwave Radiogram, 27-29 November 2020

Hello friends,

Happy Thanksgiving to listeners in the USA. I’m thankful for the great global group of radio enthusiasts who tune in, decode, and keep in touch.

Last week I mentioned that the Sunday 0800-0830 UTC broadcast (the red-eye) on 5850 and 7730 kHz can, this time of year, be heard in parts of Europe. There is, however, a Stanag 4285 data signal, apparently from the Danish Navy, on 5850, precluding most reception of WRMI on the same frequency (not directed to Europe). However, the bandwidth of the Stanag is 1300 Hz above and below 5850. Our MFSK32, about 500 Hz wide, is centered on 1500 Hz. Some of the MFSK32 data is outside the Stanag signal, and some partial decodes were reported.

For the 0800-0830 UTC transmission, I added some text in MFSK16 centered on 2200 Hz, simultaneous with the  MFSK32 closing announcement centered on the usual 1500 Hz. The MFSK16 at 2200 Hz did provide a successful decode via an SDR in Ireland. I might try it again this weekend, so tune in, especially if you are in Europe. The RSID will be for the MFSK32 at 1500 Hz, so you have to manually change the mode to MFSK16 and audio frequency to  2200 Hz.

A video of last weekend’s Shortwave Radiogram (program 179) is provided by Scott in Ontario (Friday 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 (and maybe some MFSK16), with nine images (1 x MFSK32 and 8 x MFSK64) .

Here is the lineup for Shortwave Radiogram, program 180, 27-29 November 2020, in MFSK modes as noted:

“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!
