I was afraid that eventually I would lose track of Shortwave Radio program numbers. Well, It happened in last weekend’s email. I wrote that the weekend’s show number was 133, but it was, of course, 134. And this weekend it… Leer más ›

The holidays have come and gone. Rather quickly, it seems. In any case, I hope you enjoyed the festive season. Thanks for your support and friendship in 2019, and best wishes for 2020. Listeners have alerted me to a new… Leer más ›

I hope you have been enjoying this holiday week. Thank you for the decoded images from last  weekend’s Holiday Spectacular.  One of my favorites is from Al in the skip zone of Florida, 22 December 2019, during the 2330-2400 UTC… Leer más ›

By way of a holiday card, above is last weekend’s painting of the fir tree, received by Michael in the UK, 15 December 2019, 2330-2400 UTC, 7780 kHz from WRMI Florida. Thanks to all who sent  reports last weekend, with… Leer más ›

To listeners in the USA, happy Thanksgiving! Last weekend’s experiment with Persian text was interesting and mostly successful. You can see a near perfect decode via an SDR in Kuwait (close to Iran) during the Sunday 2330-2400 UTC broadcast, 7780… Leer más ›

Thanks to those you who participated in last weekend’s test of the low-but-robust modes Olivia 32-2000 and MFSk16. There were some examples (see this example) of those two modes providing good decodes when the faster MFSK32 and MFSK64 showed errors…. Leer más ›

En las últimas semanas, la recepción de Shortwave Radiogram ha sido un desafío durante algunas de las transmisiones en algunas partes del mundo.

In the Northern Hemisphere, the shift back to winter time is complete. On our WRMI frequencies, Shortwave Radiogram stays at the same UTC times, so most of you will be tuning in those broadcasts one hour earlier by local time. On WINB’s… Leer más ›

Most of Europe moves its clocks forward this Sunday, 27 October. The WRMI transmissions will remain at their present UTC times, so they will be an hour earlier by local time in Europe. WINB usually keeps its analog 9265 kHz… Leer más ›

Que nos reportará el nuevo satélite de la NASA cuando nuestros modos digitales afecten a la ionosfera?

Thanks to Al in Florida, WD4AH, @WD4AK_Al , for moderating the @SWRadiogram Twitter account and helping with transmission tasks, 26 September-6 October, while my wife and I were in eastern Canada and Maine for a vacation. A video of program… Leer más ›

This post will provide the preview for this weekend  (26-29 September) and the following weekend (3-6 October 2019). Before that, however: Videos of last weekend’s Shortwave Radiogram (program 118) are provided by Scott in Ontario and (Sunday 0800 UTC on… Leer más ›

We are happy to know that WRMI in Okeechobee, Florida, was spared a direct hit by Hurricane Dorian. The Shortwave Radiogram schedule should, therefore, proceed as normal. WRMI was not entirely unscathed, having experienced some internet disruptions. Good luck to… Leer más ›

Please note the  new “winter” frequency, 5960 kHz, for The Mighty KBC. The schedule is below. Hurricane Dorian may be an issue this weekend. It is expected to hit somewhere in Florida on Monday. However, on Sunday, winds in the… Leer más ›

Our “hidden message” last week in the PSK125R mode was not as successful as the BPSK63F two weeks previously. Because the PSK125R is a wider mode, I had to put it as low as possible to prevent it from being… Leer más ›
