Hello friends,
Apologies for the missing transmission last weekend on 9400 kHz. I hope the Saturday's 1400 UTC broadcast is heard this without mishap.
During the broadcasts that were heard, our experiment with simultaneous English and Spanish text, using side-by-side MFSK32 streams, worked well. The dual audio caused mixing products that made the signal look somewhat messy on spectrum displays, but this did not seem to affect the decoding of the text. You can see an example of the decoded dual at the bottom of this email.
Videos of last weekend's Shortwave Radiogram (program 93) are provided by Scott in Ontario (Friday 2030 UTC) and Ralf in Germany (Sunday 2330 UTC). MDK2 in Colorado produced a video of the dual MFSK32 transmission and Hoya Boya2015 in Japan the opening segment battling QRM (both Sunday 0800 UTC). And radio no koe in Japan provided a video of the dual MFSK32 transmission from the SoundCloud audio that I posted because of the absence of the Saturday 1400 UTC transmission.The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
Here is the lineup for Shortwave Radiogram, program 94, 5-7 April 2019, 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, 5850 kHz, Thursday 0100-0200 UTC (Wednesday evening in the Americas). Also look for a waterfall ID at the beginning of the show.
Franco, HB9OAB, is transmitting digital SSTV in the KG-STV format via WINB (Pennsylvania) analog, Saturdays 2200-2215 UTC, 9265 kHz. Best reception will be via receivers in the western USA.
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 in Thor 22 or IFKP, and messages are in MFSK32 (PA NBEMS is experimenting with Thor 50x1 for messages). 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 radiogram@verizon.net , or tweet to @SWRadiogram , and I will let them know you are tuned in.
Thanks for your reception reports!
