I hope 2021 is off to a good start good, safe and healthy start for you and yours. Mine is off to a good start because I remembered not to type “2020” – at least so far.
Last week’s program offered the usual mix of good reception, bad reception, and surprising reception. You can keep track of the fun in real time or after the fact by following the @SWRadiogram Twitter account. Or if you prefer not to sign up for Twitter, point your browser to https://twitter.com/swradiogram and scroll down.
One example of interesting reception last week is this image from the Saturday 1330 UTC show by way of a very echoey (multipath) signal to an SDR in Maryland. In fact, the signal was so multipath that the image header would not decode, so I had to “graft” a good header from the studio recording. The results is an artistic rendition full of ghosts …
Videos of last weekend’s Shortwave Radiogram (program 185) are provided by Scott in Ontario (Sunday 0800 UTC on 5850 kHz, because Scott did not have good reception on his usual 15770 kHz) and by 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 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 email@example.com , 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.
