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 ›

Unless I am interrupted by some urgent task, this notice should be posted on time, i.e. before the first broadcast of Shortwave Radiogram Thursday at 2330 UTC. Which is an improvement over the late notices during the past two weeks…. Leer más ›

Sorry that I am late with this week’s notice. The first broadcast (Thursday, 11 July 2019, 2330 UTC) has already been transmitted. You can see some results below. Videos of last weekend’s Shortwave Radiogram (program 107) are provided by Scott… Leer más ›

We had a good week last weekend, with reception that was at least adequate for most listeners, and many great reception reports. Videos of last weekend’s Shortwave Radiogram (program 106) are provided by Scott in Ontario (Friday 1300 UTC), Ralf… Leer más ›

Thanks to those of you who offered suggestions and assistance as I prepare a new guide to decoding the modes, especially making the audio connection between the radio and the computer or Android device.  If I have not responded directly… Leer más ›

A prospective Shortwave Radiogram listener sent an email asking about the basic equipment needed to receive and decode the modes. This reminded me of the need to revisit the How to Decode the Modes of the Shortwave Radiogram website. It would seem all… Leer más ›

This weekend our modes will again be MFSK32 and MFSK64. These modes work very well in shortwave broadcast conditions, with MFSK32 more successful, although slower, if reception is somewhat difficult. Now we need a simple, receive-only, decode-only software for PCs,… Leer más ›
