Shortwave Radiogram, 1-3 February 2019: And the winner is …

There will be a special edition of Shortwave Radiogram today (Friday), on the WINB (Pennsylvania) DRM transmission only, at 1500-1530 UTC on 13690 kHz. See details below. All the other transmissions (analog) of Shortwave Radiogram this weekend will be the usual mix of MFSK32 and MFSK64.

On this weekend’s “normal” Shortwave Radiogram, the winner of the Tecsun Radios Australia decoding competition will be announced. Thanks to all of you who participated. There were many excellent submissions worthy of the prize, but there can only be one winner. For those of you who did not win: 1) I was not involved in the selection. 2) I never win anything, either. 3) Your participation in the competition generated commercial support for shortwave broadcasters, which helps keep shortwave alive. (And check out Gough Lui’s animated compilation of all the competition images as received by several SDRs.)

Here is the lineup for Shortwave Radiogram, program 85, 1-3 February 2019, in MFSK modes as noted:

1:42  MFSK32: Program preview
3:00  Winter SWL Fest

Special DRM edition of Shortwave Radiogram

On Friday, 1 February 2019, 1500-1530 UTC, 13690 kHz from WINB Pennsylvania, Shortwave Radiogram will experiment with some very fast text modes. The text modes will be contained in the decoded audio of the WINB DRM signal, i.e. not using the DRM system’s own text facility. The idea is that DRM is either received perfectly or not at all. If it is received perfectly, the fast text modes should work. However, due to the unusual characteristics of the WINB DRM signal, the success of the fast text modes is far from assured. In any case, they are worth a try.

Chances are that you do not have a DRM receiver. DRM can be received using the KiwiSDR receivers at in conjunction with the Dream software. Refer to these documents:

As discussed in the second document, the faad2_drm.dll decoder is necessary but must be downloaded separately, then placed in the same folder as the other Dream files.

Here is the lineup for the special broadcast:

1:34  MFSK32: Program preview
3:42  MFSK64: Immigrants kids and STEM
5:57  MFSK128: Saturn’s rings are relatively young
7:42  PSK-1000R: China’s methane regulations

11:30  16xPSK125R: Sponsored news online
12:19  7xPSK250R: Massive black hole births
13:28  MFSK128: Trump casts doubt on climate change*

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 1300 UTC on 3583 kHz USB. Check-ins are in Thor 22, and messages are in MFSK32. Messages usually 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.
