X5-Class Solar Flare is the strongest of Solar Cycle 25

Many thanks to SWLing Post contributor, Troy Riedel, who shares the following news from Spaceweather.com:

GEOMAGNETIC STORM WATCH (G2): A CME launched into space by yesterday’s X5-class solar flare (see below) *does* have an Earth-directed component. According to a NASA model, it should strike our planet on Jan. 2nd. G2-class geomagnetic storms are possible when the CME arrives. CME impact alerts: SMS Text

MAJOR X-CLASS SOLAR FLARE: Mere hours after emerging over the sun’s eastern limb on Dec. 31st, big sunspot AR3536 erupted, producing a major X5-class solar flare. NASA’s Solar Dynamics Observatory (SDO) recorded the extreme ultraviolet flash:

This is the strongest flare of Solar Cycle 25 (so far) and the most powerful eruption the sun has produced since the great storms of Sept. 2017.

Radiation from the flare has caused a deep shortwave radio blackout over the Pacific Ocean: blackout map. Mariners and ham radio operators may have noticed loss of signal at all frequencies below 30 MHz for more than 60 minutes after the flare’s peak (2155 UT).

SolderSmoke: 7J6CBQ on Okinawa — And a Translation of a Science Fiction Novel about Ham Radio in China

Many thanks to SWLing Post contributor, Bill Meara who shares the following article from the excellent SolderSmoke Podcast:


7J6CBQ on Okinawa — And a Translation of a Science Fiction Novel about Ham Radio in China

The article about Sergeant Malik Pugh USMC on Okinawa brought back memories from the 1990s. David Cowhig was 73 Magazine’s Hambassador on Okinawa — I had the same “position” in the Dominican Republic.  David and I were both in the Foreign Service;  we joked that 73 had afforded us our only chances to be ambassadors of any kind.  David’s Okinawa QSL and the opening from his initial report to 73 magazine appear above.  You can see more here:

A couple of my own “dispatches” as Hambassdor to the Dominican Republic appear here:

Back in the 90’s David sent me an old QST Magazine.  I wrote about this on the SolderSmoke blog:

Later, I learned about another “Hambassador” who was still active as a radio amateur: Ron Gang 4X1MK:

Finally (and this is really cool):  David Cowhig has been putting his language skills to good use, translating Chinese written material.  He sent me his translation of the opening chapters of a Chinese science fiction novel about ham radio.   Readers of the SolderSmoke Daily News will like this:

Mediumwave DXer logs KFIZ from Arctic Finland

Many thanks to SWLing Post contributor, Ulis Fleming, who shares the following article from KFIZ via Twitter. I love these articles where a mediumwave DXer blows the minds of a small AM radio station’s staff!

Finnish man hears KFIZ radio transmission on radio in Artic Circle

A man from Finland contacted KFIZ recently to let us know he was listening to our station IN Finland earlier this month. And while it doesn’t sound like such a big deal since we do announce you can listen around the world on the “Tune In” app, this person actually heard us on the AM spectrum of frequencies.

Jari is a self described AM radio enthusiast in Finland that says he is passionate about listening to and identifying AM stations from around the world.

In early December, Jari travelled about 750 miles from his home in southern Finland, by train and car, to an isolated area in Northern Finland, well into the Artic Circle, where he has a base station set up designed to pull in AM radio signals from around the world. Jari says conditions are ideal there because there is ample space for long antennas and little to no man-made electrical noise or interference.

On December 4th at 6:00 Universal time, which would have been midnight local Fond du Lac time, Jari recorded a transmission on his receiver. Its very faint but it’s our station’s radio ID that we play often throughout the day that says “News Talk 1450, KFIZ Fond Du Lac – a Mountain Dog Media Station.”

Given how hard it is to hear, you can respect the fact that Jari now has transmissions confirmed from over 800 stations from North America.

While generally AM radio waves only travel at most 100 miles from the transmitting antennas, with the right conditions, usually during the nighttime hours, AM radio waves can reflect off the ionosphere and propagate past the curvature of the earth, a phenomenon called “skywave” propagation.

So from all of us here at KFIZ, if you are listening locally, on the tune in App, or isolated deep within the Artic Circle, we want to say thanks for listening.

TEF6686 DSP Chip and the Qodosen SR-286

Many thanks to SWLing Post contributor, TomL, who writes:

A couple of weeks ago, “Radio Jay Allen” sent out a review of a Chinese portable using a different DSP chip from NXP called the TEF6686 usually used in car radios with lots of features. I also notice that the description for the new 2024 WRTH lists an in-depth an article about the TEF6686 chip. Does anyone else know about the new chip or the portable that was reviewed? Is it better than the current crop of portables based on Silicon Labs chips?

Here is a link to the review of the portable radio:
