Kintsugi -- A Japanese Philosophy for the Owners of Imperfect Rigs
On Sun, Aug 29, 2021 at 4:05 PM Bob Scott wrote:
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.
— Christy Bartlett, Flickwerk: The Aesthetics of Mended Japanese Ceramics73,Bob KD4EBM
--------------------------------------------
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.

EI7CLB's Ladybird Receiver (George Dobbs Design), and Voice over the Internet
Friday, January 22, 2021
Jenny List's Favo(u)rite Things
Over on Hack-A-Day Jenny List (G7CKF) has a really nice article about ham radio and homebrewing. She truly has The Knack: She got her start in radio electronics at age 9 when her parents gave her George Dobbs's Ladybird book.
https://hackaday.com/2021/01/21/a-few-of-my-favorite-things-amateur-radio/
One of her paragraphs really seemed to capture the SDR-HDR conflict that we so often joke about:
The age of the homebrew RF tinkerer may be at a close, at least in the manner in which I started it. Nobody at the cutting edge of radio is likely to be messing around with discrete transistor circuits in the 2020s, unless perhaps they are working with extremely exotic devices up in the millimetre wavelengths. It’s all software-defined radios, opaque black plastic boxes that deliver a useful radio experience on a computer but that’s it. No more homebrew, no more tinkering.
Whew, good thing I'm not on the cutting edge. It sounds kind of sad. Oh well, that leaves more discrete transistors for us to tinker with.
Jenny's Profile on Hack-A-Day:
[Jenny List]: Contributing Editor and European Correspondent
Jenny List trained as an electronic engineer but spent twenty years in the publishing industry working on everything from computer games to
dictionaries before breaking out and returning to her roots.
She grew up around her parents’ small farm and blacksmith business in rural England, so making (and breaking) things is in her blood. Countless projects have crossed her bench over the years, though these days you’ll find her working with electronics and in particular radio, textiles for clothing and costume, decrepit classic cars, and real cider from first principles.
When she’s not writing for Hackaday she works on language corpus analysis software, designs and sells amateur radio kits, sits on the board of Oxford Hackspace, and is a freelance electronic design engineer and programmer.

The Bitsy -- Homebrew Double Sideband from Scotland
This is such a beautiful project: it involves DSB, homebrew, troubleshooting, George Dobbs, SSDRA, J310s, a box kite, and ham radio nostalgia. I was struck by how similar the Bitsy looks to some of my own DSB creations (but the Bitsy is nicer). I'm really pleased to find a DSB project coming out of the UK -- when I was there, DSB was kind of frowned upon by spectrum preservation zealots. I say there is plenty of room for the very few homebrew DSB rigs that will ever grace the airwaves with their presence. Thanks John. Have fun with all your projects. 73 Bill
Hi Bill
In the early 80's I built and experimented with Direct Conversion Receivers and had a lot of fun with them. I came across a 40M DC cw transceiver by the late Rev. George Dobbs in a Practical Wireless magazine and decided to build it. Whether I was just lucky I'm not sure but it worked first time and I had several cw contacts with it. It was called “The PW Severn”. I then discovered DSB and looked into modifying the wee rig. I gave George a phone, no internet in those days, and explained what I was proposing to do and if there was any advice he could offer. His reply was , “it should work so try it and see, any problems get back to me”. It worked and I had a lot of fun with it. I used to take it portable and with a box kite to support a long wire and worked all over Europe.
It was after reading and learning about
circuits and home brewing I wondered if I could design and build a DSB
transceiver of my own. I had plenty of articles and most importantly a copy of
Solid State Design, now well thumbed.
So the “Bitsy” was born. It is an 80M DSB
transceiver. The PA produces about 2 watts. I took what I thought was the best
for each module and built it using six circuit boards which I designed and
etched myself. Nowadays I use the Manhattan method for one of circuits. It is
much easier and quicker.
Like most home brew projects, the fun is in
the building and the wee rig lived in a box for several years. Probably over
30. My doesn't time fly. I came across it again while looking through my boxes
and decided to give it an airing. Expecting it to work on power up I was quite
shocked when it produced nothing on both receive and transmit. After staring at
it for a couple of minutes I unscrewed the lid and studied the wiring for a dry
joint. Nothing so I switched on my Digital Multimeter and Oscilloscope. I soon
found out that the output from the VFO was missing. The VFO uses one FET and
two PNP Transistors for the buffers. The scope soon proved that the FET was
faulty. I used an MPF102. These are hard to get so I replaced it with a J310.
While I had the VFO out I also replaced the 9.1v zener diode, which provides a
regulated voltage for the FET, with a 78L05 connecting the centre pin via a
580ohm resistor to earth. This gives me a 9.3v regulated supply for the
oscillator. It is now back in full working condition.
With the Covid 19 epidemic I, like a lot of
the Amateur Radio fraternity, am spending a lot of time in the shack and
looking for new projects. I am buying back my old FT200 which was my first rig.
An old friend and lapsed amateur has still got it and agreed to sell it back to
me. It is still in a good condition for being nearly 50 years old and just
needs some TLC. When it is finished it will take pride of place beside my
restored Heathkit SB104A. And they say nostalgia is not what it used to be!!

make it fit. (on the back fence).
WIth 5 watts CW on 40m I can hit the USA reverse beacons most mornings.
It was about £9 ($11) to make - but if you count the Spiderbeam
12m pole, it was another £98 ($120).
I have a little George Dobbs story relating to aerials. Probably around
him and have a beer with afterward.

We have lost our spiritual leader: George Dobbs G3RJV, SK
Yesterday we received the very sad news that George Dobbs, G3RJV has died.
I think it is no exaggeration to say that with George's passing, we have lost our spiritual and philosophical leader. The founder of the G-QRP Club and Editor of our beloved SPRAT journal, George took his strong technical skills and his talent for writing and combined it with the wisdom about life that came from his religious vocation. He was a prolific writer and speaker, and in all his work you will find a unique combination of the technical and the philosophical. Not only did he teach us how to build our own rigs, but he taught us why we should build them.
We talk a lot about tribal knowledge -- George was definitely the source of much of that. But he went beyond that and also became a major source of what we can call tribal wisdom. He was one of our tribal elders. Instead of speaking to the tribe around a roaring fire, George spoke to us through SPRAT, through articles in other ham magazines, through his books, and through his talks at rallies and hamventions, many of which have been preserved in YouTube videos. George's friend Tony Fishpool sent us the one embedded below.
We are of course very sad to see George go, but we can all take comfort in the fact that he will -- through his writings and through his recorded talks -- remain with us. For years to come people who feel a strange urge to build their own radio equipment will find themselves reading George's work or listening to recordings of his melodious voice. They will find there not only the needed technical information, but also the encouragement and tribal wisdom needed to carry on. There will be a bit of George Dobbs in all their rigs. In that way G3RJV will stay on the air. And I know that George would be delighted by that.
73 G3RJV.

SPRAT -- The 007 Connection
Wow -- I just knew those GQRP guys had to be much cooler than they seemed. I guess there were some indications: They do seem to talk quite a bit about "Q". There is that weird fondness for Parasets. I understand that several of the senior GQRPers drive Aston Martins. And that Dobbs guy -- a kindly retired Anglican minister you say? Really? I can just hear him saying it: "Dobbs, George Dobbs."

Listen to Keith Ranger G0KJK on "QSO Today"
http://www.qsotoday.com/podcasts/g0kjk
Wow Eric,
I just listened to all of the Keith Ranger interview and was struck by the eerie parallels between YOUR 24 September podcast and OUR 24 September SolderSmoke podcast:
-- Both shows discussed the involvement of Anglican clergy in the hobby.
-- Both discussed the joys of simple QRP gear.
-- George Dobbs G3RJV came up in both.
-- BOTH featured discussion of the BD139 transistor (!!!)
-- Both discussed the use of ceramic resonators in ham circuits.
Great minds think alike!
I really enjoyed your interview with Keith. I have enjoyed reading in SPRAT about his projects -- years ago I built his MB4 receiver. I listened while I worked on my homebrew receiver. It was the ideal accompaniment. I also like the stickers on his transmitter.
Please pass this on to Keith if you can.
Thanks and 73 Bill

I also liked Keith's comments on the joys and perils of amateur electronic engineering.

QRP Wisdom from George Dobbs, G3RJV

An Irish Knack Story
Thanks for the great podcasts and also to Pete for his unique contributions. I have been interested in radio since I was a kid but only really got back into the hobby in 2009. Back when I started playing with electronics in the 1970's I hankered after a soldering iron of my own. I bought the one in the picture in 1977. A "modest" 60 watt job, it was the cheapest one in the shop but I used it to harvest parts from all manner of abandoned old iron. I was really surprised to find it clearing up recently. The snips in the picture was a tool that my late Uncle had surplus and passed on to me, it too played a role in my scavenging for parts. In Ireland in the 1970's it was hard to get parts. I remember my Grandmother taking me from Galway to Dublin - 3 hours each way!!!) to buy parts for my first project, Rev. G.C. Dobbs venerable transistor radio from the "Making a Transistor Radio" book by Ladybird. I still have the book and the dusty remnants of the radio, long since plundered for parts. When I returned to the world of radio it wasn't long before I discovered QRP and the GQRP club. It was a real surprise to find the good Reverend was at the helm there. I just thought that the picture and story might raise a smile amongst followers of the blog. Thanks to yourself and Pete for the podcast. Keep up the great work! QRP Forever!
