We are seeing signs of the changing seasons. Changes in the amount of daylight versus darkness affect our weather, and they affect the condition of the ionosphere, which affects shortwave reception and optimum frequencies.

The anniversary of the 9/11 terrorist attacks, earlier this week, generated memories of that event, including the role of the mass media. While I am still able to remember 23 years ago, I decided to post a series of tweets… Leer más ›

Hello friends Thanks to Jinling for voicing the introduction to last week’s program 367. My voice is back now, so you will hear me again this week. This week in northern Virginia, we endured temperatures as high as 99F/37C. Local… Leer más ›

Hello friends Heat has overtaken much of North America. Here in northern Virginia, the outside temperature reached 90F/32C, which was our cue finally to turn on the air conditioner — more for the humidity than for the actual temperature. Fortunately,… Leer más ›

Hello friends As I type this, I am hearing what the meteorologists on the radio refer to «an occasional rumble of thunder.» I’m sure it won’t last, on this otherwise beautiful day. Days such as this, not too hot with… Leer más ›

Hello friends The recent intense solar activity has certainly made shortwave reception «interesting.» Most Shortwave Radiogram broadcasts were affected to some degree, but all the broadcasts were audible at least some place. As usual, our MFSK32 text performed well in… Leer más ›

Hello friends, In last week’s email, I wrote «It will be hot enough, soon enough.» Well, as I type this, it is 90°F/32°C in Arlington, Virginia. And we obstinately have not turned on our house’s air conditioning. The AC is… Leer más ›

Hello friends, An active sun has resulted in some recent disruptions to shortwave propagation. Generally Shortwave Radiogram has been lucky in sidestepping these events, so let’s hope this pattern holds up. And while solar activity can cause brief dropouts on… Leer más ›

Hello friends There are no transmissions of Shortwave Radiogram during the time of the solar eclipse on April 8. But that might be an interesting time to listen shortwave or even medium wave radio. The theory is that frequencies usually… Leer más ›

Hello friends, Spring is officially here, although today here in northern Virginia, the temperature did not rise above 50F/10C. And the wind made it seem cooler. Another recent feature of our local weather has been wildfires, mostly in the mountains… Leer más ›

Hello friends Program 344 will be another déjà vu edition of Shortwave Radiogram. Due to family activities in our house the program transmitted 1-6 March 2024 will be repeated 9-14 March. And to add to the confusion, because of North America’s… Leer más ›

Hello friends The holiday season generates many colorful photos to include in Shortwave Radiogram. Most of this week’s MFSK images will continue in that theme. While searching for seasonal images, some content sources were upfront about the fact that their… Leer más ›
