Shortwave Radiogram, 13-16 June 2019

This weekend our will again be MFSK32 and MFSK64. These modes work very well in shortwave broadcast conditions, with MFSK32 more successful, although slower, if reception is somewhat difficult. Now we need a simple, receive-only, decode-only software for PCs, and app for mobile devices, that decode MFSK 16, 32, 64, and 128 …

MFSK16 (55 wpm) for difficult conditions
MFSK32 (120 wpm) for fair conditions
MFSK64 (240 wpm) for good conditions
MFSK128 (480 wpm) for excellent conditions (e.g. local FM or medium wave)

The software should be able to decode, and optionally save, both text and images.  An RxID would detect which flavor of MFSK is being transmitted and the center audio frequency.  

Everything went smoothly last weekend except that the first broadcast of the weekend, Thursday at 2330 UTC, was the previous week’s show. This was because of a problem with the automated playout system at WINB.

This weekend’s show is in MFSK32 and MFSK64, with nine images.

Here is the lineup for Shortwave Radiogram, program 104, 13-16 June 2019, in MFSK modes as noted:

 1:59  MFSK32: Program preview
 2:47  Pieces of glass can be recycled into concrete*
 8:17  MFSK64: Czech brewery rolls out first wastewater beer*
12:18  Michelin and GM unveil airless tires*
15:58  This week’s images*
28:33  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, 9395 kHz, Thursday 0130-0230 UTC (Wednesday evening in the Americas). Also look for a waterfall ID at the beginning of the show. .

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 1200 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1200 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 (PA NBEMS is experimenting with Thor 50×1 for messages). 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.
Thanks for your reception reports!
