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:

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:

Sci-Fi Series with an Apollo-era Vibe

Kind of fun.  The Apollo-era and Saturn V stuff bring back memories of 1969 and all that. It is a series that you can watch on Apple TV. 

Here is a review:

Europa -- "Attempt No Landing There."

As we get ready to send two probes to the Galilean moons of Jupiter, this sci fi movie made its way into my feed.   It is pretty good, and the ending will appeal to all true radio amateurs.

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:

 https://soldersmoke.blogspot.com/2009/09/carrington-flares-aurora-where-were-you.html    

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. 

Jagadish Chandra Bose

Jagadish Chandra Bose

(30 November 1858 – 23 November 1937)

Acharya Sir Jagadish Chandra Bose, was a Bengali polymath, physicist, biologist, botanist, archaeologist, as well as an early writer of science fiction. He pioneered the investigation of radio and microwave optics, made very significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent. IEEE named him one of the fathers of radio science. He is also considered the father of Bengali science fiction. He also invented the crescograph.

Born in Bikrampur (present day Munshiganj District near Dhaka in Bangladesh) during the British Raj, Bose graduated from St. Xavier's College, Calcutta. He then went to the University of London to study medicine, but could not pursue studies in medicine due to health problems. Instead, he conducted his research with the Nobel Laureate Lord Rayleigh at Cambridge and returned to India. He then joined the Presidency College of University of Calcutta as a Professor of Physics. There, despite racial discrimination and a lack of funding and equipment, Bose carried on his scientific research. He made remarkable progress in his research of remote wireless signaling and was the first to use semiconductor junctions to detect radio signals. However, instead of trying to gain commercial benefit from this invention, Bose made his inventions public in order to allow others to further develop his research.

Bose subsequently made a number of pioneering discoveries in plant physiology. He used his own invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for a patent for one of his inventions due to peer pressure, his reluctance to any form of patenting was well known. To facilitate his research, he constructed automatic recorders capable of registering extremely slight movements; these instruments produced some striking results, such as Bose's demonstration of an apparent power of feeling in plants, exemplified by the quivering of injured plants. His books include Response in the Living and Non-Living (1902) and The Nervous Mechanism of Plants (1926).

......Bose's education started in a vernacular school, because his father believed that one must know one's own mother tongue before beginning English, and that one should know also one's own people.

Speaking at the Bikrampur Conference in 1915, Bose said:

“At that time, sending children to English schools was an aristocratic status symbol. In the vernacular school, to which I was sent, the son of the Muslim attendant of my father sat on my right side, and the son of a fisherman sat on my left. They were my playmates. I listened spellbound to their stories of birds, animals and aquatic creatures. Perhaps these stories created in my mind a keen interest in investigating the workings of Nature. When I returned home from school accompanied by my school fellows, my mother welcomed and fed all of us without discrimination. Although she was an orthodox old-fashioned lady, she never considered herself guilty of impiety by treating these ‘untouchables’ as her own children. It was because of my childhood friendship with them that I could never feel that there were ‘creatures’ who might be labelled ‘low-caste’. I never realised that there existed a ‘problem’ common to the two communities, Hindus and Muslims.”

Thanks to K.P.S. Kang for alerting us to this.

Mars is BACK! 2020 Opposition! Don't Miss it!

2004 

Sometimes waking up a bit earlier when the sunrise is coming later leads you to some interesting things.  

It was quite humid in Northern Virginia on the morning of 25 August 2020, but the skies were surprisingly clear.  I stepped outside at about 0500 local time, coffee cup in hand.  Venus was blazing in the east.  Then I saw this big very bright red thing high in the southern sky.   It seemed almost too bright and too high in the sky to be Mars.  But a quick check with Stellarium showed that it was in fact the Red Planet.  I pulled out my six inch Dobsonian reflector telescope and soon had Mars in the eyepiece.  

For the first time in many years I could see surface features:  It is springtime in the southern hemisphere of Mars, but the Southern Polar Cap (which recedes in the summer) was still very prominent (in my eyepiece it was near the top, as in the GIF above) .  I could also see an albedo (dark on light) feature below the icecap.

I went out again on the morning of 26 August 2020.  Again the Southern Polar Cap was very visible.  Below it, near the center of the disc,  I could make out a large albedo feature.  I am pretty sure that is Mare Erythraeum.  

Above is what Stellarium presented as Mars as viewed from Earth this morning. The Southern Polar Cap is much more prominent in my telescope (you can see it in the upper right in the image above).  The large dark thing near the center of the disc is Erythraeum.  In the Stellarium image you can see the enormous Vallis Marinaris canyon shooting off to the lower right (sadly I could not see this in my telescope). 

The GIF at the top of this post gives a much better view than I get with my little six inch telescope.  The GIF gives a good idea of what the albedo features and the ice cap look like.  

This was a great time for me to see these things.  I'm almost done with the second book in Kim Stanley Robinson's Mars Trilogy -- much of the story takes place in sanctuaries carved under the Southern ice cap, and in Hellas (which Robinson's colonists are filling with water).  During the 2018 Earth-Mars opposition a big dust storm made it impossible for me  to see anything on Mars; a similar storm takes place during book one of Robinson's Trilogy. And right now the Perseverance rover is on its way to Mars.  

This 2020 opposition will be the best one until 2033.  So don't miss it. 



Here is a good article on observing Mars during the current opposition:

Here are technical details on the 2020 opposition:

Mars: Book Review, Martian Propagation, Martian Moons as VHF Repeater Sites

In SolderSmoke #224 I mentioned the Mars Trilogy by Kim Stanley Robinson.   I found a book review in The New Yorker (see below).   In Red Mars they mention that there is no ionospheric propagation on Mars.  W1PJE and K1RID point out that this is incorrect -- there is ionospheric propagation on Mars.  K1RID provides a link to a really detailed NASA study of this question (it includes discussion of the effect on propagation of Martian dust storms -- good to know!). Finally, 2E0CHK suggests placing VHF repeaters on the two moons of Mars.  I found a good article about the overhead passes of these moons.   See below for all.  

AND REMEMBER: THE ELSER-MATHES CUP REMAINS UNCLAIMED! 


Here's a review from The New Yorker:

----------------------------------

Hello Pete and Bill,

Listened to your latest SolderSmoke podcast. Enjoyable as always. But you should correct the record: Mars does have an ionosphere!

https://www.google.com/amp/s/www.wired.com/2017/04/mars-ionosphere-cold-lifeless-filled-heavy-metals/amp

The peak daytime electron density ("M2 layer") is low in altitude - perhaps 130+ km, about our E region - and density is like our E region too (5-10x lower than our F region). So for the Mark Watneys carrying their Homebrew rig and inverted V, probably only a few hundred km to the first skip zone. More NVIS flavor than anything else.

Fun to think about. You should go and test it out!

Hey Bill,
No skip on Mars ?
No ionosphere ?
Every cloud has a silver lining, even if Mars doesn't have any clouds ;)
Mars has two moons.
Could be paradise for Moon Bounce aficionados. No ionosphere or F layer to get in the way. VHF can get around corners after all.

Opening Scene of Contact (CQ at the end)

Mike Herr's video on his use of an Arduino to call CQ SKN made it onto Hack-A-Day 
yesterday and provoked some discussion there of the meaning of CQ.  One fellow posted 
this opening scene from the movie Contact.   I thought you guys would like it.

Radio Drama about RADIO!

Dale, W9DKB, alerts us to a radio drama from 1973 that is all about mysterious radio signals from space. Very cool. Thanks Dale.
.....................................

Hi Bill,

I've enjoyed your podcast for the past 2 years, never miss it. And I enjoyed your book, Global Adventures.

Last night I listened to a free radio show from Jim French Productions and thought of you. It's a story that involves computerized data signal processing, communication with aliens, radio noise analysis, NASA, Apollo, Skylab, deciphering codes based on chemical specific gravities, neat jazz music ... all the things a knack victim like yourself would enjoy. And here's the kicker - the production was made in 1973! You can hear the old 500 series Bell telephones used for sound effects and all that. Give it a listen. I think you'll like it.

This is an episode of "Dameron". If you like listening to radio dramas, this is a great site to visit as they post a new show on their "Listen Now" page each week. The Harry Nile adventures are great. But so are the Adventures of Sherlock Holmes. Of course all of them are available for download at a modest cost. (No, I have no affiliation with Jim French Productions.)

http://jimfrenchproductions.com/zc137m/index.php?main_page=page&id=2&chapter=0
is the link. Scroll down the page. The show you want is titled WEEK 804, Dameron, "Earth is Ours". Just click the blue "Listen Now" label.
