Last week’s Shortwave Radiogram was very colorful, except for the two gray-scale (also known as grey-scale) images, which were very “blackandwhiteful”. See one example below and many more at https://twitter.com/swradiogram or @SWRadiogram on Twitter.



However, apologies for the malfunction last weekend on 9400 kHz. It sounded like CW, but I don’t think it was. The problem was resolved before the end of the transmission. Let’s hope it does bot happen again this Saturday. (A studio recording of last weekend’s broadcast, with no malfunctions, is available here.)



Videos of last weekend’s Shortwave Radiogram (program 91) are provided by Scott in Ontario (Friday 2030 UTC) and Ralf in Germany (Saturday 1400 UTC, including the transmitter issue). Additional video from 1400 UTC is contributed by radio_no_koe in Japan. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.



The Pennsylvania NBEMS Net (listed below) is experimenting with the Thor 50x1 mode for messages. We will therefore experiment with it on this weekend’s Shortwave Radiogram.Thor 50x1 is faster than MFSK32 (176 vs 120 wpm) and wider (900 vs 630 Hz). There will be eight MFSK images (1 MFSK32 and 7 MFSK64).



This weekend’s program also includes news about the HAARP spring research campaign, 25-29 March, including an artistic element in the Scotte 1 SSTV mode.



Here is the lineup for Shortwave Radiogram, program 92, 22-24 March 2019, in modes as noted:



1:38 MFSK32: Program preview

2:42 HAARP Gearing Up for its spring research campaign*

9:03 Thor 50x1: New internet legislation in Russia

12:06 MFSK64: Proposed budget cuts RFE/RL language services*

“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, 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.
