Shortwave Radiogram, del 3 al 5 de Diciembre 2021: programa 233

Apologies to those of you tuned in last Saturday at 1330 UTC on 15770 kHz. You were detecting a carrier but heard no audio of Shortwave Radiogram or anything else (until 1400 UTC). Jeff White at WRMI responded to my email, explaining “our System D computer died.” Because we were listening ardently to 15770, we knew his System D computer was down before Jeff did. Anyway, System D is fixed now.

Amazingly, it’s already December. The truck that comes down our street to vacuum leaves will be here soon, but many leaves are still on our trees. The wall calendar has not caught up with the climate’s calendar. This weekend’s images will include some lingering autumn as well as some emerging winter.

Last weekend, we has some fun with multipath reception. During the Friday 1300 UTC transmission, Al in Florida received the Astra rocket launch via short path (330 km) and long (or longer) path (39745 km) (left below). During that same transmission, using an SDR in South Australia,I received the rocket short path (16000 km) and long path (24000 km). Roger in Germany explained the phenomenon

A video of last weekend’s Shortwave Radiogram (program 232) is provided by Scott in Ontario. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 233, 3-5 December 2021, in MFSK modes as noted:

“This is a Music Show” 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, Thursdays at 0200-0300 UTC on 5850 kHz (Wednesday evening in the Americas) and a new time also on WRMI, Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) .

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 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!
