The (Real) Solar Flare of August 1972 in Cixin Liu's Science Fiction

 

A view of McMath Region 11976 from the Paris Observatory early on 4 August 1972. 

I have a vivid memory of seeing -- as a kid -- Aurora from our home near New York City.  Eric Carlsen, my childhood friend and colleague from the Waters Edge Rocket Research Society,  told me his mom had similar memories. A while back I did some Googling and concluded that it had to have been the monster solar flare of  August 1972:

That blog post got about eight comments, mostly from other folks with similar memories -- they apparently were led to my blog by the same kind of memory-based Googling that I had done. 

This year, on Christmas Eve, Elisa and I were flying home from the Dominican Republic. I was reading (on my phone) "To Hold Up the Sky," an anthology of Cixin Liu's science fiction short-stories.   I'd read his excellent "Three body Problem" in the Dominican Republic back in December 2017.   His work is usually "hard" sic-fi, with a strong connection to real physics.

One of the short stories in the anthology is entitled "Full Spectrum Barrage Jamming." Wow, I thought, that one is really promises to be very interesting for a radio amateur.  I turned out that it was more interesting than I expected. 

I won't spoil the story for you.  Suffice it to say that Cixin Liu makes reference to the same August 1972 solar flare that I remember from my childhood, and discusses its effect on radio propagation.  It was really kind of eerie to be in that plane, flying over the Bahamas, reading Chi-Fi on my I-phone, and seeing the author reference that memorable event from 1972.  TRGHS. 

There were plans to turn this story into a movie: https://www.yicaiglobal.com/news/wandering-earth-producer-to-film-another-liu-cixin-novel

Here is an excellent article describing what happened back in 1972: https://room.eu.com/article/lessons-from-the-sun.   The August 1972 flare was so strong that it caused U.S. Navy anti-ship mines to explode in Haiphong harbor in Vietnam. 

Jonathan-san (Our Man in Japan) Now Melting Solder in Seattle

Got a nice note from Jonathan W0XO.  He and the family  have relocated to the Seattle area.  Here we see Jonathan at work in his new shed/shack.  It looks great. 

Long-time SolderSmoke fans will remember Jonathan from his previous life in Asia. See:

From Vietnam to Washington DC -- Jonathan-san KC7FYS W0XO 7J1AWL XV2OC Stops By With His AT3b

I first saw that QRP Altoid-tin ATS-3b rig  around 8 years ago in pictures that Jonathan-san sent from a beach in Vietnam.  He and his family were there on vacation from Japan.  (Included was a memorable picture of his young son in an NVA helmet.) During this time period Jonathan also tried (unsuccessfully, I'm afraid) to teach me how to properly pronounce the name of that famous electronics market in Japan.  

Jonathan and his family were in Washington yesterday and we got together for lunch.   It was great to finally meet them.  And to see that well-travelled ATS-3b.

Jonathan is a big fan of the ATS-3b, and for good reason.  A very neat rig.

Plug in filters for the ATS-3b.

Voice of Vietnam on Old (New!) Regen Receiver

I'm having a lot of fun shortwave listening with the reborn British regen.  This is the Voice of Vietnam. 

I rebuilt the regen using the old Eddystone variable capacitors, the original coil form, the original wooden chassis (now covered with copper flashing) and the original front panel and knobs.  But the old triode was replaced by an  MPF-102 JFET.  And the AF amp tube was replaced by an LM386. Something old, something new... The circuit is the old Armstrong circuit, with a tickler coil and throttle cap.  Thanks to Charles Kitchin for all the regen wisdom in his Nov/Dec 1998 QEX article (available on-line).

AL7RV's Zenith Transoceanic from Vietnam days

Bill,

Glad the junk box is providing useful. Enjoyed your Blog about the great Ham Radio day you had. I got the same feeling when my Paraset 350v power supply came alive without letting any of the all important 'smoke' out. I did get 'bit', and had a flashback to the days of my youth that involved my Weller Soldering gun and a GE tube manual. I tried to build every circuit in the back of the manual and got 'bit' by most of them. Heck the shocks keep our batteries charged right?

I'm side tracked on a project to construct a 455Kc BFO for a Zenith Trans-Oceanic 3000-1. I purchased the radio at the Tan Son Nhat BX/PX during my first month in country. (~68). The radio spent a year in Vietnam and a little over two more years in Thailand. Used to wrap my fatigues carefully around it and pack tightly in the center of my duffel bag. Held up pretty darn well.

I've dug the radio back out and am having a ball with it. It's helping me a LOT with my Spanish language relearning efforts. But I do lament the lack of English programming on shortwave today.

The Zenith became our main source for news rather then the much edited and heavily censored AFRN. I would patch the audio output of the radio into a spare MUX channel going off to another signal site and they would in turn patch it to other sites in Vietnam. I head stories that in some camps the local AFRN low power FM radio transmitter feed would be pre-empted with the BBC World News that was coming from my Zenith.

Hey, are you enjoying the cold weather! hihihihi...

On the Air (QRP) from Vietnam

Our friend Jonathan, 7J1AWL, managed to overcome the bureaucratic barriers, and was on the air from some really beautiful locations in Vietnam.
Check out his pictures and videos: XV2OC
I really like the shot of Oscar in the helmet.
