Around 11:30 p.m. on Feb. 4, 1872, the sky above Jacobabad suddenly brightened, as if a portal to heaven had opened. A passerby watched in amazement and terror, while a pet dog became motionless, then trembled. The godly glow morphed, from red to bright blue to deep violet, until morning.
Electric communication cables mysteriously glitched in the Mediterranean, around Lisbon and Gibraltar, London and India. Confused telegraph operators in Cairo reported issues in sending messages to Khartoum. One incoming message asked what was the big red glow on the horizon — a fire or a faraway explosion?
This of course reminded me of the event that I witnessed as a teenager in New York in 1972:

That post has resulted in a steady stream of comments, mostly from non-hams. Apparently people remember seeing the event, then search the web for clues as to what it was. Google brings them to that post on the SolderSmoke Daily News. The comments are usually along the lines of, "Wow! I saw it too!" Very cool.
And here is a 2022 Turkish media interview with Hans and his team in the workshop:

Thank you Klaus! And thanks to JF3HZB! (Does anyone have more information on him?)
I usually try to listen in on the Old Military Radio Net on Saturday mornings (3885 kc). Lately I listen with my Mate for the Mighty Midget receiver.
This morning's session was especially good. For me the highlight was when Masa AB9MQ called in from Normal, Illinois using his Central Electronics 20A (see below). That was one of the earliest SSB rigs. A phasing rig, it also ran AM (which was what Masa was using this morning). He had it paired up with a Central Electronics 458 VFO. You folks really need to check out Masa's QRZ.com page:
Buzz W3EMD called in from Rhinebeck, NY. I could hear his dynamotor in the background. Buzz said hello to Masa in Japanese. FB.
Always great to hear Mike WU2D.

There is a LOT of tribal knowledge and lot of great ideas on his site. Kazuhiro-san has apparently quit wireless, but is climbing mountains near his home. We hope is doing well and that he will someday return to radio (perhaps for the peak of cycle 25).
We last posted about him back in 2011. In the comments to that post you can see the sad news about the demise of his web site (which is now back on the web):

JF1OZL's bio:
My name is Kazuhiro Sunamura. I am a 50 year old mechanical engineer, born in 1956. I am not an engineer in electronics. I have been interested in electricity and radio from the age of ten. For the last ten years, I have been active on my ham radio station JF10ZL. I have also written articles about my some of my radio projects in Japanese for the Japanese CQ Magazine. Now I have decided to get onto the internet and will take the opportunity of showing you my equipment and ideas. Please have a look at my schematics. I will be very happy if this material helps you with your own radio projects. I am a member of the J.A.R.L. affiliated Tsuchiura Club, the local ham club in my home town.
Hi Bill:After listening to the latest Soldersmoke I thought you might find the Japanese concept of "kintsugi" (literally "golden joinery") interesting.From Wikipedia: https://en.wikipedia.org/wiki/Kintsugi#Philosophy As a philosophy, kintsugi is similar to the Japanese philosophy of wabi-sabi, an embracing of the flawed or imperfect.[11][12] Japanese aesthetics values marks of wear from the use of an object. This can be seen as a rationale for keeping an object around even after it has broken and as a justification of kintsugi itself, highlighting the cracks and repairs as simply an event in the life of an object rather than allowing its service to end at the time of its damage or breakage, and can be seen as a variant of the adage "Waste not, want not".[13]
Kintsugi can relate to the Japanese philosophy of mushin (無心, "no mind"), which encompasses the concepts of non-attachment, acceptance of change, and fate as aspects of human life.[14]
Not only is there no attempt to hide the damage, but the repair is literally illuminated... a kind of physical expression of the spirit of mushin....Mushin is often literally translated as "no mind," but carries connotations of fully existing within the moment, of non-attachment, of equanimity amid changing conditions. ...The vicissitudes of existence over time, to which all humans are susceptible, could not be clearer than in the breaks, the knocks, and the shattering to which ceramic ware too is subject. This poignancy or aesthetic of existence has been known in Japan as mono no aware, a compassionate sensitivity, or perhaps identification with, [things] outside oneself.

I shared Bob's Kintsugi message with David, WA1LBP. David was one of the few radio amateurs in the ranks of the Foreign Service. He was in Okinawa during the early 1990s, when I was in Santo Domingo. For a time we both wrote columns in the "73 International" section of Wayne Green's magazine -- this made us "Hambassadors." David is a real scholar of difficult Asian languages. During my last years in government service I would sometimes cross paths with David at lunch time on the National Mall in Washington -- he'd be out there with a colleague, studying ancient Chinese poetry.
Here are David's thoughts on this:
Thanks, Hambassador Bill.Chan embraced this account of nonduality and Buddha-nature, but distinctively used it to qualify the meaning of Buddhist practice and the personal ideal of the bodhisattva. In the Platform Sutra attributed to Huineng, he insists that
meditation is the embodiment (ti) of wisdom, and wisdom is the functioning (yong) of meditation.
The point of Chan is to see one’s own “original nature” (benxing, 本性) and realize “authentic heartmind” (zhenxin, 眞心), and in doing so the dualities of thought and reality, of passion and enlightenment, and of the impure and pure all dissolve. Then,
true suchness (zhenru, 真如) is the embodied structure (ti) of thinking, while thinking is the functioning (yong) of true suchness. (Platform Sutra, 13–17)
To see our own original nature is to see that true suchness and thinking are as intimately related as the bodily structure of a horse and its customary activities. Just as the bodily structure of the horse establishes the conditions of possibility for grazing and galloping, it is only the proven evolutionary advantage of grazing and galloping in horse-like ways that have made this bodily structure possible. True suchness or ultimate reality is not a preexistent something “out there” that can be grasped intellectually or accessed through some mystical vision; it can only be enacted.
Huangbo Yixun (d. 850) describes this as demonstrating no-“mind” (wuxin, 無心) or freedom from conceptual impositions that would define or limit reality. But this is not a lapse into mental blankness or indiscriminate presence. Realizing no-“mind” restores our originally whole mind (yixin, 一心) that Huangbo qualifies as the “silent bond” (moqi, 默契) of “conducting oneself as all Buddhas have” (in Taishō shinshō daizūkyu, Vol.48, 2012.380b to 383c). Significantly, the term “qi” originally referred to notches or tally marks on a strip of bamboo that record the terms of a trade agreement and the bonding that Huangbo invokes is thus one of mutually entrusted obligation and responsibility. True suchness consists in the personification of the bodhisattva ideal of realizing liberating forms of relationality. Ultimate reality consists in enacting the morally-inflected nonduality of wisdom and compassion.

I remember that it was George Dobbs, G3RJV who introduced us to the concept of Wabi sabi:

From the obituary in the Washington Post:
In addition to the Nobel Prize, Dr. Akasaki’s honors included a 2009 Kyoto Prize — Japan’s highest honor — recognizing developments in advanced technology. He found that some technology, however, needed no advancing at all. He took great pleasure, for example, in long-playing classical music records.
On that point, he joked, “I am analog.”
He is the 2014 winner of the Nobel Prize for Physics. He is the person who figured out how to make blue light LEDs through the use of an Indium Gallium Nitride semiconductor. I was reading about him this morning in "Conquering the Electron" by Derek Cheung and Eric Brach. Thanks to Nakamura, the numerals on all my frequency displays glow in a pleasing Juliano blue. Three cheers for Nakamura!
