Retro QRP Rigs of the 1960's, 70's, and 80's -- Video by Mike WU2D


It is time to put aside (again!) all of the heated ideological arguments about the power level that defines "low power."  Just sit back and enjoy this wonderful trip down QRP memory lane. 

Mike's description of the simple, single-transistor QRP transmitter was really nice.   I recently made something similar: https://soldersmoke.blogspot.com/2023/02/first-qso-with-high-school-receiver-100.html  And Mike does a nice plug for our beloved Michigan Mighty Mite.  Go CBLA! 

The modular idea:  words to live by my friends. 

40673!  TT2!  And G3RJV's PW Severn - indeed, bow your heads!

Wow, the Ten Tec Power Mite (or Might!) -- I still want one.  Same for the Argonaut -- what a great name (sounds like a "magic carpet), and with SSB to boot!  I want to join the Argonaut cult! 

I have both the HW-7 and HW-8 (the HW-8 is heading to the Dominican Republic).  This video makes me want to fire up the HW-7.  Maybe on 40.  

My 40 meter homebrew rig (Digi-Tia) has in it the filter from that old Yaesu FT-7 rig.  The filter was given to me by Steve "Snort Rosin" Smith.  https://soldersmoke.blogspot.com/2015/05/bitx-digi-tia-build-update-2-installing.html  


Thanks to Mike for including me in the credit roll at the end.  What a great group of people -- it is a real honor to be listed with those folks.

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.  
 

       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 Ceramics

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

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.

In Buddhism, muxin (in Chinese wuxin) is about freeing oneself from troubling thoughts, distractions, and selfishness and so attaining a calmness that is very aware of all that goes on at the same time.  I suppose once free from distractions one can be more alert.  So maybe not literally no mind but no-selfish-obsessed-mind

Amazing what one can find online. A distraction too I suppose!


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.

David 

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

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

https://soldersmoke.blogspot.com/2010/04/homebrew-hero-george-dobbs-g3rjv.html


This philosophical embrace of imperfection and repair is very appealing to me.  I am surrounded by old radios that bear the marks of wear, tear and repair.  My homebrew radios are filled with imperfections (especially in the cabinetry).   But Kintsugi tells me this is all OK.  I accept it. 

Thanks Bob.  Thanks Hambassador David. And thanks to George Dobbs.

Michigan Mighty Mite, Joy of Oscillation, and the Color-Burst Liberation Army in Washington State

 

Perhaps its the result of a vaccine-induced relaxation of COVID tensions, but for whatever reason we are seeing a resurgence of interest in the Michigan Mighty Mite and the Color Burst Liberation Army. 

Dan AF7O describes his excellent MMM CBLA adventure here: https://af7o.campclan.net/?p=144  Extra points for the use of George Dobbs' Ladybird book technique, and for the 3D printed variable cap holder (made by Dan's son). 

Yes Dan, rebuild that antenna, build an LP filter, and get that MMM on the air.  At the very least you can get some reports from the Reverse Beacon Network.  And, as Jack NG2E recently demonstrated, it is possible to make contacts with a simple rig like this: 


LONG LIVE THE COLOR-BURST LIBERATION ARMY!

EI7CLB's Ladybird Receiver (George Dobbs Design), and Voice over the Internet

 

I suggested that Tryg once again gather the parts to build George Dobbs's Ladybird receiver.  He should use the same wooden base.  That would be great.  

As for VOIP, I told Tryg that SolderSmoke got its start in a VOIP program  called Echolink -- Mike KL7R and I used to converse from London to Alaska.   Mike recorded one of  our conversations, and that became SolderSmoke #1.  I was using VOIP even before that -- from the Dominican Republic in the mid 90's I was connecting my Radio Shack 2 meter HT to an early VOIP program Internet  Phone or I-phone.  The company that made it was an Israeli firm called Vocaltech.   

---------------------------
Hi Bill,

Thanks for the recent emails and podcasts. I have attached a picture of my first radio - or at least what is left of it. I plundered it for parts down through the years as you can see. It is the build from the late Reverend George's "Making a Transistor Radio", the Ladybird book that really put the hook in me all those years back. I was probably only 11 when my late Grandmother and I went to Dublin by train (300 mile round trip) to Peats of Parnell Street to buy what components my pocket money could afford in order to build the first couple of stages of the radio, The wooden base was cut for me by a worker at a local furniture making factory here in Galway. He got a great laugh out of it when I told him I was going to build a radio - he kept putting the wooden blank up to his ear and joking: "I can't hear anything yet!". I will always remember it.

On another front I wanted to thank Pete and yourself for an entertaining and informative couple of podcasts. I made the leap a couple of months back and bought a set of boards for a uSDX (W2CBA version) but I may just use it as a receiver if I ever get around to building it. I don't know yet. The kit that Pete mentioned in episode #228 really got me excited. I expect you can imagine that my imagination is running riot at the moment.

Finally, I would be interested to hear about your take on half duplex VOIP apps such as Peanut. I realise that it is not 'real' radio to many but I have enjoyed several contacts with operators around the world with it and it has been quite satisfying. These ops that I have spoken with have often been infirm, elderly or have mobility issues. There are also a couple that are under HOA restrictions. One OM in particular lives in a retirement village and is a full-time carer for his wife. I think it is a good thing that they can still be involved in radio without all of the physical demands it might make on them or annoying their neighbours. It might, at least, it might be a worthwhile topic for discussion. Thanks again for an excellent Podcast. BTW, I am a bit of a guitar nut too - is that a Stratocaster that Pete is holding in the picture on the Soldersmoke Blog Page?

Right ho, time to put the kettle on. Tea is a vital component for operational efficiency in my radio world!

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.

Thanks Jenny!

Pete N6QW and Steve G0FUW Talk to RSGB About Homebrew (Video)


Wow, what an unexpected treat!  Here we can watch Pete N6QW and Steve G0FUW talk to the Radio Society of Great Britain about homebrew radio.  Steve talks about kits and scratch-built rigs.  I really liked seeing his early rigs and his description of how building these rigs helped him become a more advanced homebrewer.  I also liked his mention of George Dobbs as a guiding light in the QRP and homebrew world. 

Pete focuses on SDR and provides a really great description of this approach to homebrew.  I was struck with how great it is that, after a lifetime of HDR building, Pete is willing to embrace this new technology. He talks about it as part of "a learning journey."  As always, he sets the example for us all.   

Thanks to Pete, Steve, and RSGB.

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!!

Antennas, Money, and Ham Psychology


During SolderSmoke Podcast #222, Pete lamented the fact that many hams are willing to spend significant amounts of money on "manufactured" dipole antennas that are little more than pieces of wire.  Tony Fishpool G4WIF sent a graphic on the wire antenna he uses (see above).  He also shared an anecdote about G5RV antennas and G-QRP Club founder George Dobbs:  

From Tony: 

The aerial that I’ve had so much fun with, an End Fed Half Wave, cost me £8 ($9.80) for the toroid and the rest came from the junk box. The reel of wire was probably a £1  ($1.25) from a radio rally. You never pay big money for wire at a rally. People take it there to get rid of
it!

It covers 80m and all  harmonically related bands.
My garden is too small so I cheated by using some linear loading to
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
15-20 years ago. He was speaking at a radio club near to me so I went along to support
 him and have a beer with afterward.

He gave his usual entertaining (and always funny) talk during which he
paused - and said, as if in confidence to the audience:

“Do you know, I’ve heard, and I don’t know if it is true, that there are
people who actually pay real money for a pre-made G5RV”

I swear that it went very quiet and there may even have been the odd foot
shuffled.    Tony

Coincidentally Mike, WU2D put out a VERY ILLUMINATING YouTube video on the psychological aspects of ham radio operators and their antennas.  Here it is:

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.

Carpentry and Socketry for the uBITX


Yesterday I decided to spend some time at the bench -- I wanted to get the uBITX boxed up.  My basswood box had arrived from Amazon on Friday.  It was time for what George Dobbs G3RJV called "socketry."  

First, the back.  I figured I would need five connectors back there.   Connectors for 12V DC, speaker, and antenna would be needed right away (it is my preference to have the speaker connector on the back of the BITX).  Looking ahead, I might want to also have a jack for T/R control of my linear amplifier, and a jack for 24 VDC if I want to go wild and put more voltage on the drains of the IRF510s. So I put two extra holes in there.  


Basswood is SO easy to cut.  I put the LCD in the center of the front panel, and opted to put the board close to the front of the board.  This avoids the need for jumpers to connect the Raduino to the LCD, and it keeps the lines to the front panel controls and connectors very short. I mounted the board on the spacers that came with the BITX, drilling holes the bottom of the basswood box.  It all fit quite nicely. 


I would need to put two jacks on the front panels:  key jack and mic jack.  And I'd need two controls: main tuning and AF gain.  I used hole saws to cut holes big enough to accommodate the four items. 


The controls and jacks were then placed on two small pieces of copper clad board.  These then went on the front panel.  

Wiring up the uBITX was  easy.  I just followed Farhan's instructions.  I did the wiring AFTER placing the boards and controls in the box -- this helped me keep all the wires at their optimum length (not too long, and more important -- not too short!).  If you do it this way, put a cloth over the boards so you don't drop solder blobs on the uBITX. 

Farhan's uBITX fired up nicely as soon as I applied power.   The receiver really sounds nice.  I hope to make some contacts with it today. 

Three cheers for Farhan!

SPRAT -- The 007 Connection


The eagle eye of Brent KD0GLS spotted this frame in the 007 movie "Casino Royale."  
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.

An Irish Knack Story


I think Tryg should get that Ladybird receiver working again. 
-------------

Hi Bill,

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!

Occam's Bench: M0XPD on the Minimalist Measurement Mindset



Our ace correspondent in Dayton, Bob Crane W8SX, caught up with Paul Darlington M0XPD (above, the guy with the rifle) and interviewed him about his presentation at Four Days in May 2016.  You can listen to the interview here by clicking on the link below.   I especially liked the comments on the joys of fixing things and the advantages of SIMPLE analog circuitry. Listen to the end and you will learn about Paul Darlington's connection to the famous Darlington Pair.

From Paul Darlington M0XPD: A Book!


Our friend Paul Darlington M0XPD is a member in good standing of the International Brotherhood of Electronic Wizards. His AD9850 Arduino shield propelled me into the world of I and Q. His "Shack Nasties" blog is a valuable resource for all of us. And now he has written a book.  Paul was kind enough to let me read it before it was published -- I enjoyed it very much.  It is the story of a very personal journey. At one level it is about Paul's trip to the Dayton Hamvention.  But the trip goes much further than Dayton, both geographically and personally.  I especially enjoyed Paul's observations on the United States -- our British cousins often see things we ourselves overlook.   I'm really pleased that George Dobbs wrote the foreword -- he is the ideal person to do this for Paul's very philosophical book.

We give "Getting There" our highest review:  the coveted FIVE SOLDERING IRONS. And we are nominating Paul for a Brass Figlagee with Bronze Oak Leaf Palm.  

Read Paul's description of the book here:

Congratulations Paul!
