Reception of Shortwave Radiogram was generally good last weekend. Thanks for all you reports. We in the US Atlantic seaboard had unusually good reception on 15770 kHz on 12 December after the usual difficult reception the day before. For listeners in Europe, this reminder that the the Sunday 0800-0830 UTC broadcast, 5850 and 7730 kHz, actually directed to Asia, might be audible this time of year, especially west and north.
Last weekend, we did not see any examples of dramatic multipath reception in the small image created by Roger in Germany. We’ll try it again in the new year. The decoding of images under multipath conditions can look like this (from a previous show) …
A video of last weekend’s Shortwave Radiogram (program 182) is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
This weekend’s show is in the usual MFSK32 and MFSK64, with eleven images (1 x MFSK32 and 10 x MFSK64).

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.
