We’ve had two frustrating weeks with out Friday 1300-1330 UTC broadcast, 15770 kHz from WRMI Florida – which is usually the transmission that reaches the farthest in world. Last week, Shortwave Radiogram was missing, with the Overcomer Ministry in its… Leer más ›

Listeners have noticed that our transmission Tuesday at 1430-1500 UTC on 9955 kHz from WRMI Florida – usually difficult to receive during the summer – has been replaced by other content. Today I received confirmation from WRMI that the French… Leer más ›

We use Twitter @SWRadiogram extensively to share results of Shortwave Radiogram reception, and to send reminders about transmissions during the weekend. It is a simple and functional platform for that purpose. But, with uncertainties about the future of Twitter, I… Leer más ›

This was a big week in our house. I installed a new Verizon Fios router, with the help of a Verizon representative on the telephone. We were FiOS (as it was capitalized back then) customers since it was introduced to… Leer más ›

This week in northern Virginia, we have an unusual visitor: rain. It rained most of yesterday, and it will rain, at least a bit, during the next few days. This won’t completely break our drought, but any precipitation helps. Meanwhile… Leer más ›

I hope the fires, smoke and haze that affected much of North America in the past week have not had major adverse effects on you. I don’t think they will impede our MFSK transmissions. Thanks to all of you who… Leer más ›

Thanks to Daz Man in Australia for producing last week’s special EasyDRF transmission. And thanks to everyone who participated by tuning and decoding, or attempting to decode, whether you were successful or not. When it worked, the EasyDRF results were… Leer más ›

Our transmission on Saturdays, 2300-2330 UTC, 7570 kHz from WRMI Florida, has been suffering from wide-band interference on the same frequency. The interference is intermittent: sometimes it’s there, sometimes not, sometimes it lasts for several minutes, sometimes just for a… Leer más ›

I hope everyone has recovered from the Program 300 celebration last week.🙂 Now we settle into our pattern of MFSK32 text, MFSK64 text, and MFSK64 images. We find the MFSK32 and MFSK64 work best in typical shortwave reception conditions. And… Leer más ›

As I type this, the windows in my office are open. Through the screen I can hear the grass-cutting machines, which seem to be a permanent feature in our neighborhood. Temperatures here in northern Virginia reached 87F/31C this week, and… Leer más ›

This will be another weekend of changes: Most of Europe will move its clocks forward on March 26. That same day the A23 HF (shortwave) frequency season begins. Many shortwave broadcast stations will change frequencies to adjust for seasonal propagation…. Leer más ›

This is the time of year when time changes and frequency changes can complicate our shortwave listening. In most of North America, clocks will move forward one hour on Sunday, March 12. The only impact this weekend is that the… Leer más ›

Snow and ice will affect much of North America this weekend. Good luck if you and your antennas are affected. Down here in Virginia, the weather will remain boring except for higher than normal temperatures. Shortwave reception will not be… Leer más ›

As I type this, it’s warm (65F/18C) here in northern Virginia. The cold weather will return, and it would be nice to see some snow before winter is over. The spring-like weather is a reminder that seasonal changes to propagation… Leer más ›

In the northern hemisphere, nights are still long enough that our “red-eye” transmission Monday 0800-0830 UTC on 5850 kHz often reaches the western parts of Europe. Sometimes a Stanag military data signal is also on 5850, but the Shortwave Radiogram… Leer más ›

During the afternoon, while napping, I received an email from WINB indicating that they were not able to retrieve this weekend’s program that I uploaded to their FTP site. I tried again under a different filename. If that problem has… Leer más ›

I hope you have been enjoying the holiday season. Best wishes for the new year. Bear with me if I type “2022” a few times when I should type 2023. And if you were affected by Winter Storm Elliott (where… Leer más ›

Our transmission last Tuesday at 1530 UTC on 9955 kHz was not on the air due to some issue at WRMI. I am hearing WRMI now (2255 UTC) on 9955, so whatever the problem was, it’s resolved now. Our newest… Leer más ›

I hope listeners in the USA had a good Thanksgiving. And good wishes to everyone as the holiday season develops. See The Mighty KBC section below for news about their future frequency and transmitter site. A video of last weekend’s… Leer más ›

There is one correction to the Shortwave Radiogram schedule to announce: The WINB DRM transmission is Friday at 1500-1530 UTC. And its frequency is 15755 kHz, up five kilohertz from the 15750 kHz WINB had been using the past few… Leer más ›

Hello friends WRMI has restored several of its frequencies after damage to its antennas by Hurricane Ian. Unfortunately, last weekend, most of the frequencies used by Shortwave Radiogram were not among the frequencies back on the air. We will not… Leer más ›

Our thoughts are with Shortwave Radiogram listeners in the path of Hurricane Ian and its associated storms and rainfalls. We wish you minimum disruptions. WRMI in Okeechobee, Florida, experienced a power failure for several hours. Their power is restored, but… Leer más ›

I woke up from an afternoon nap to learn of the death of Queen Elizabeth. As a shortwave listener, I remember listening to her Christmas messages on shortwave (our preferred technology), and later via newer media. Events compelled me to… Leer más ›

Last week (program 268) an automation problem at WRMI Florida shifted the frequency for the 1300 UTC Friday show (August 19) from 15770 (which had classic hits instead) to 5850 kHz. Sorry for this unfortunate surprise. If this happens again,… Leer más ›

Here in the Washington DC area, we are finally enjoying some relief from the heat and humidity. Our windows were open all day today. Nighttime temperatures will be below 70F (21C), for the famous “sleeping weather.” We will still experience… Leer más ›
