Shortwave Radiogram, del 24 al 27 de Marzo: programa 249

This will be complex weekend. On March 27, most of Europe turns clocks ahead for Summer Time. And, same date, the A22 shortwave frequency season begins.

Most Shortwave Radiogram frequencies stay with UTC, so for most Europeans, the show will be heard one hour later by local time. WINB’s 9265 kHz and WRMI’s 9955 kHz stay with North American Eastern Time, which moved forward on March 13, so effective March 27 local times will be the same for most Europeans.

Also on March 27, WRMI will swap its 7730 and 7780 kHz frequencies (to avoid interference to aircraft). So as of that date, our Sunday 0800 UTC broadcast will be on 5850 and 7780 kHz. And the Sunday 2330 UTC show will be on 7730 kHz.

The Mighty KBC, Sunday 0000-0200 UTC, will remain on its frequency of 5960 kHz until May 1, when it will change to 9925 kHz. Also, The Mighty KBC will have a special transmission for Europe, Sunday, March 27, 0800-1500 UTC on 6095 kHz from transmitter site Nauen, Germany. (0800-1000 Live from the 60’s with The Real Don Steele. 1000-1400 The Classic Hit List with M.G. Kelly. 1400-1500 The Giant Jukebox with Eric van Willegen.) Our minute of MFSK64 will be transmitted at 1430 UTC on 6095 kHz (in addition to the usual 0130 on 5960 kHz). Reception of 6095 kHz will be unlikely in North America, so try SDRs in Europe.

Videos of last weekend’s Shortwave Radiogram (program 248) are provided by Scott in Ontario (Friday 1300 UTC) and Ralf in Germany (Saturday 1330 UTC). See also a video by KD8TTE on HF/MF image transmission. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

“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) . Also look for a waterfall ID at the beginning of the show. . @ThisIsAMusicSho

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 , 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!
