Here in Washington DC area, Inauguration Day (January 20) passed without incident. I monitored the local 2-meter repeaters for “situation” reports, but, fortunately, there were no situations to report. Last weekend’s reception provided more adventures in winter (or summer, depending… Leer más ›
Mid-winter (in the Northern Hemisphere) has created several opportunities for good shortwave reception – and some frequencies that are impossible to hear, depending on your location. You can see listeners’ results at Twitter @SWRadiogram, or if you don’t have a… Leer más ›
I hope 2021 is off to a good start good, safe and healthy start for you and yours. Mine is off to a good start because I remembered not to type “2020” – at least so far. Last week’s program… Leer más ›

Reception of Shortwave Radiogram was generally good last weekend. Thanks for all you reports. We in the US Atlantic seaboard had unusually good reception on 15770 kHz on 12 December after the usual difficult reception the day before. For listeners… Leer más ›
Reception last weekend was difficult in some parts of the world, but there were plenty of good decodes nevertheless. A good place to see results reported by listeners is the @SWRadiogram Twitter account. If you are not on Twitter, point… Leer más ›
Hello friends, Because of increased solar activity, and because of conditions generally during these months near the solstice, reception and decoding will be interesting in the next few weeks. For example, the 15770 kHz transmissions, directed to Europe, might be… Leer más ›
Hello friends, Happy Thanksgiving to listeners in the USA. I’m thankful for the great global group of radio enthusiasts who tune in, decode, and keep in touch. Last week I mentioned that the Sunday 0800-0830 UTC broadcast (the red-eye) on… Leer más ›

Shortwave Radiogram experimentara con las nuevas modalidades MFSK32WIDE y MFSK64WIDE en las próximas emisiones.
Apologies for the missing transmission Sunday, 18 October, 2330-2400 UTC on 7780 kHz. It’s an old WRMI transmitter, and such interruptions occur occasionally. The transmitter is back on the air now, and let’s hope it’s still operating this Sunday…. Leer más ›
Last week’s experiment with Olivia 32-1000 at 2000 Hz produced several
examples from listeners of the Olivia 32-1000 succeeding when the MFSK32
and MFSK64 text mostly failed and my voice introduction was generally
inaudible
With difficult reception this time of year in some parts of the world,this weekend we will transmit a slow, robust mode: Olivia 32-1000 (32 tones, 1000 Hz wide). The extra “twist” in this exercise is that the Olivia 32-1000… Leer más ›
Last week’s experiment with MFSK16 produced some successful decodes when the MFSK32 and MFSK64 text was less than 100%. I had a couple examples on 15770 kHz from WRMI Florida using SDRs in Russia and Ukraine. For some reason,… Leer más ›
Perhaps because of equinox propagation, reception of Shortwave Radiogram has been difficult lately in some parts of the world. Listeners in the eastern half of North America have been especially affected, with many of our frequencies (15770 for example)… Leer más ›

Last weekend, it was, as usual, difficult to find a Shortwave Radiogram signal bad enough to provide a good test for our slow modes: Olivia 64-2000 and MFSK16. There were, however, a few instances of Olivia 64-2000 succeeding where the… Leer más ›
