Shortwave Radiogram, 26-28 April 2019

Last weekend's Japanese text was decoded in Japan, in some cases partially, and in others 100%. This weekend, we will try another brief excerpt of Japanese text, but this time in MFSK16, which is slower and more robust than our usual MFSK32. We will also raise the center audio frequency to 2000 Hz to try to escape any interference from voice transmissions. Turn on your RxID to guide Fldigi to the correct mode and audio frequency. If the RSID does not work, a 10-second tuning signal will help you manually tune to the correct audio frequency. MFSK16 requires precise tuning of the audio frequency for correct decoding. 

Here is the lineup for Shortwave Radiogram, program 97, 26-28 April 2019, in MFSK modes as noted:

 1:46  MFSK32: Program preview
 4:09  MFSK16: Japanese text (at 2000 Hz)
 8:05  MFSK64: New solar panels for high altitude UAVs*
11:37  Wireless power transfer (WPT) potential radio interference
13:18  BIRDS-3 cubesats delivered to the ISS
15:34  This week's images*
28:18  MFSK32: Closing announcements

Slow Scan Radio transmits is taking some time off until early May. Then it will transmit SSTV images and text modes Saturdays at 1300-1330 UTC on 6070 kHz and 7440 kHz via Channel 292 in Germany. The website is http://www.slowscanradio.com. Reception reports to x@xdv.me.

The Mighty KBC transmits to North America Sundays at 0000-0200 UTC (Saturday 8-10 pm EDT) on 5960 kHz, via Germany. A minute of MFSK is at about 0130 UTC.  Reports to Eric: themightykbc@gmail.com . See also http://www.kbcradio.eu/ and https://www.facebook.com/TheMightyKbc/. 

“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.

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 50x1 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 radiogram@verizon.net , or tweet to @SWRadiogram , and I will let them know you are tuned in.
 
Thanks for your reception reports!
