Shortwave Radiogram, del 21 al 23 de Enero: programa 240

For days, the weather forecasters were warning us that two inches of snow would arrive here in the Washington DC area during the Thursday morning commute. Two inches may not seem like much if your are used to real snowfalls, but it’s enough to create chaos on the roads here. The local school system canceled classes the night before the forecast weather event. So Thursday morning arrives and … nothing. Just a bit of rain. Snow is a reluctant visitor to the Washington DC area.

We did get the un-fun part of winter, today: The temperatures dropped. But at least there was no snow, so I was able to repair my two wire antennas.

Last weekend I transmitted an image with two red stripes on a dark blue background. (It could be a nice flag for an emerging republic.) I was hoping the stripes would show effects of multipath reception. Multipath is sometimes seen if one lives close to the transmitter site. The short skip-zone signal can be weak enough that the signal coming the long way around Earth is also received, creating the echo sound and the fascinating ghosting of the images. The stripes looked like this to Al in northern Florida,14 January 2022, 1300-1330 UTC, 15770 kHz from WRMI Okeechobee, farther south in Florida.

This weekend, to detect any multipath we’ll try a blue diamond, recommended by our expert Roger in Germany.

Pop Shop Radio from British Columbia, Canada, includes “a whole variety of pop music, such as records from the 1960s and 1970s that were played on Top-40 radio stations not only in North America but also on offshore radio and stations like Radio Luxembourg.” The programs now include some MFSK32 text and an image. Schedule: Via Channel 292 in Germany: Wednesdays 1600-1630 UTC on 3955 and 6070 kHz. Saturdays 2200-2230 UTC on 3955 and 6070  kHz (except 6070 first Saturday of the month 2300-2330 UTC).

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!
