As I type this, our part of northern Virginia is under a flash flood warning. And thunder is rumbling. I should finish this email quickly, because it does not take much around here to bring about a power failure.
A video of last weekend’s Shortwave Radiogram (program 221, Friday 1300 UTC) is provided by Scott in Ontario. Also, from the same transmission, a demonstration of acoustic coupling to TIVAR by sunplio aka @HFSolar1. 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 1300 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1230 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. 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 firstname.lastname@example.org , 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!
