The heat and humidity seem even worse than the heat and humidity for which this region is famous. Or maybe advanced age is making it more difficult to withstand the heat and humidity. Around 3 or 4 am, I turn off the AC and open the door from our bedroom to a screened balcony, to let… ## [Shortwave Radiogram, 6-13 August 2026 (program 461): I would probably get a middle seat on that 24-hour flight](https://swradiogram.net/post/824237171532808192) _2026-08-06 · https://swradiogram.net/_ Many Thanks to Al Holt and Tony Pavick for providing Shortwave Radiogram 460, an interesting look at the time signal stations of the United States and Canada, and the QSL cards they issued. I was pleased that one of my WWV QSL cards, from 1966(!), was included. I am not so pleased that Canada's CHU is now absent from the shortwaves. If you missed the program, you can use the video provided by… ## [Shortwave Radiogram, 30 July-6 August 2026 (program 460): At the tone, Tony and Al’s program about time signal stations](https://swradiogram.net/post/823594488415092736) _2026-07-30 · https://swradiogram.net/_ This week, Tony Pavick and Al Holt of the Shortwave Radiogram team present a history of time signal stations with special focus on WWV, WWVH, WWVB, WWVL, and (RIP) CHU. There are also images of QSL cards from these stations as well as brief audio clips, making the presentation truly multimedia. This will be an interesting show, so tune in and decode! A video of last week's Shortwave Radiogram… ## [Shortwave Radiogram, 23-30 July 2026 (program 459): Digital modes that crash into the moon](https://swradiogram.net/post/822969888951910401) _2026-07-23 · https://swradiogram.net/_ Uncommonly nice summer weather is visiting us in northern Virginia. It's 82F/28C with low humidity as I type this in front of an open window. High temperatures will be below 90F/32C for the next week, which is a good stretch for us. This week's Shortwave Radiogram includes a news story and image from Radio Taiwan International (Rti), about their participation in an amateur radio event in Japan.… ## [Shortwave Radiogram, 16-23 July 2026 (program 458): Changing modes in the middle of a story.](https://swradiogram.net/post/822331582796939264) _2026-07-16 · https://swradiogram.net/_ The thermometer just outside Shortwave Radiogram World Headquarters (a room not much larger than a closet) shows 97F/36C. The air conditioner serving this upstairs part of the house is half-heartedly keeping the indoor heat and humidity down. I hope you are staying cool wherever you are. This week's Shortwave Radiogram will have only one text news item, split between MFSK32 and MFSK64 because of… ## [Shortwave Radiogram. 9-16 July 2026 (program 457): Digital modes that can be transmitted via old analog landline telephones](https://swradiogram.net/post/821693532113928192) _2026-07-09 · https://swradiogram.net/_ Thanks to Tony Pavick and Al Holt for producing the very interesting programs 455 and 456 of Shortwave Radiogram. And to Marty Pittinger for watching over the Bluesky and X accounts, with reminder posts and reposts. Yesterday (July 8) I emailed some decoding results of Tony's show (455), featuring logos and test patterns of the Canadian Broadcasting Corporation and Radio Canada International. That… ## [Shortwave Radiogram, 18-25 June 2026 (program 454): Digital modes that will clean the barnacles off your ship](https://swradiogram.net/post/819798458868301824) _2026-06-18 · https://swradiogram.net/_ Last week's test of the Olivia 32-2000 provided some successes where the MFSK32 had some or many errors. There were also instances in which the Olivia 32-2000 had a few errors. I think the Olivia 64-2000 would have been perfect in such reception conditions. We will compare modes when the Extreme Shortwave project starts in a few weeks. The most dramatic example of the Olivia 32-2000 was during the… ## [Shortwave Radiogram, 11-18 June 2026 (program 453): Official digital modes of the East India Company](https://swradiogram.net/post/819165355625824256) _2026-06-11 · https://swradiogram.net/_ A new transmission time for Shortwave Radiogram has been added. It is UTC Monday 0030-0100 UTC (Sunday evening in the Americas) on 5050 kHz from WRMI Florida. The 5050 frequency from WRMI is heard well in Florida and the Caribbean, but beyond those areas reception of 5050 is DX. This provides an opportunity to test our slower text modes. In fact, this time slot will eventually be taken over by… ## [Shortwave Radiogram, 4-11 June 2026 (program 452): Some Olivia among the MFSK](https://swradiogram.net/post/818530267781283840) _2026-06-04 · https://swradiogram.net/_ Put on your official Shortwave Radiogram white lab coats, because we will be experimenting this week on program 452. After the usual MFSK32 and before the MFSK64, there will be a brief message in Olivia 64-2000 about "Extreme Shortwave," a new project that will be a companion to Shortwave Radiogram. To receive Olivia 64-2000 (64 tones, 2000 Hz wide), make sure the SQL (squelch) in the bottom right… ## [Shortwave Radiogram, 28 May-4 June 2026 (program 451): End time for CHU](https://swradiogram.net/post/817897934547976192) _2026-05-28 · https://swradiogram.net/_ The first news story on this week's Shortwave Radiogram is about Canada's plans to close the shortwave time station CHU in June. Many of us have tuned in CHU over the decades to get a an accurate time reading. In my eastern US location, CHU is often easier to hear than WWV. I have often thought that our MFSK32 modes could be added to CHU or WWV for time and general announcements. In difficult… ## [Play Both Sides Of The Lie (Sponsored)](https://crawlproof.com/a/jIjO7UbDgvAU) _2026-05-28 · **Sponsored**_ Two operatives, one manufactured war — uncover the Complete Truth after both campaigns. ## [V32 Farsi/Iranian numbers station](https://www.iz0kba.it/en/farsi-numbers-station/) _2026-03-02 · IZ0KBA · IZØKBA Lorenzo_ 7842, 7910 kHzUSB On the same day, after the start of the conflict between the USA and IRAN, transmissions of numerical sequences in Fārsī language (فارسی Fārsī, persian language spoken in Iran) began on the frequency of 7910 kHz USB; radio enthusiasts initially thought it could be an new Iranian numbers station.
