Hello friends
The NASWA Winter SWL Fest will take place March 4 and 5, 2022. This annual meeting covers all aspects of the radio listening hobbies, on all frequencies. This year, again, it will be virtual, via Zoom, due to the pandemic. Information at swlfest.com.
Last week, we again experimented with multipath reception. I received the example below during the Friday 1300-1330 UTC broadcast, using an SDR in South Australia. Because the signal on 15770 kHz from WRMI Florida reached South Australia with about the same signal level short path (16000 km) versus long path (24000 km), very little text was decoded, including none of the MFSK image headers, I had to "graft" a good header from the studio recording. The result is a blue triangle provided to us by Roger in Germany. The short-path diamond is on the left, the long-path diamond on the right. This is because the lines in the image "paint" from left to right. The short-path and the long-path were received 26 milliseconds apart. The thicker blue segment in the middle is where the SP and LP overlapped,
Analysis of the image above is provided by Roger. Roger also received a dramatic multipath example during the Saturday 1330-1400 UTC broadcast, using an SDR in New Zealand.
Videos last weekend's Shortwave Radiogram (program 240) are provided by Scott in Ontario (Friday 1300 UTC), GC!bor C)n in Hungary (Friday 1300 UTC except: no decode but you can decode from his audio), and Frigid RF in Virginia (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

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 1230 UTC on 3583 kHz USB. Check-ins are usually in Thor 22, and messages are in MFSK32. 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. USEast NBEMS Net: Please also note the USEast NBEMS Net, Thursdays 0000 UTC (Wednesdays 7 pm EST) on 3536 kHz USB.
Thanks for your reception reports!
