Civility, Ham Radio, King Hussein, and the International Brotherhood

Hi Bill,

Interested to hear you talking about civility ... My introduction to amateur radio was via a Heathkit GR 64 and Roy, G3PMX. When I finally took my ticket - 1970, and passed, I called him on the phone to tell him - he told me to come on up to his QTH, I did, via an old bike taking about 30 minutes to get up the hill. When I got there, he put me on the mike, the guy the other end was really great, talked about being a part of an international brotherhood and a movement for world peace - just a magical first contact ...

Roy asked me if his call seemed a little odd, it did, it was short, JY1, but I was really slow to cotton on to who I'd just spoken to... What really blows me away to this day was that the King of Jordan sat in his shack and waited for a 16 year old kid to pedal up the hill just to give him a fantastic first contact ... My only regret is that I never got to speak to him again to say "thank you" - when you talk about legacy radios, it isn't the tech that we need to hold on to, though we do, it was what that man did to reach out to a fellow amateur.
 
By all accounts, he was a fantastic guy, he used to sit at Roy's kitchen table drinking coffee and just being one of the guys ... Sadly I was at sea by then hence not meeting him.

Roy knew him because he worked for Marconi & put the antennas on the palace, Hussein just appeared having that Roy was an amateur and they had a long conversation about radio - when he turned to leave, Roy asked his name so that he could stay in touch - Hussein told him to just ask for Hussein the radio guy - never let on that he was King ...
 
Roy said that on several occasions, JY1 travelled to the UK more or less incognito and hired fairly innocuous cars to get about the country simply because he was here as an amateur, not a head of state …

 

I really do regret that I never got the chance to say “thank you” to him – it was the sort of gesture that I have always thought typifies what you have tried to support and continue, and is indeed carried on by the likes of Joe Taylor who once took the time to respond to an email from me explaining how to set a WSPR system up despite being Nobel Prize winner !! 
 Great example of the spirit of amateur radio transcending all else :-)

 73s, Nick, G8INE

Mighty Mite with Homebrew Capacitor Made from Two Cans (video)

Paul Hodges, KA5WPL, didn't have the variable capacitor called for by the Michigan Mighty Mite schematic.  So in the true spirit of the International Brotherhood of Electronic Wizards, he rolled his own!  He used two empty aluminum cans and some electrical tape.  Wow,  that's really cool Paul. 

You have truly earned you membership in the Color Burst Liberation Army, and for the capacitor I award you the prestigious Brass Figlagee with Bronze Oak Leaf Palm.

Listening to Chinese Satellites with my Drake 2-B

On September 22, 2015 at around 1120 UTC I was able to hear the CW beacons from the fleet of new amateur radio satellites put into orbit by China.   Here is a recording:

Very cool.   This reminded me a lot my early experiences with the Russian RS satellites in the 1990s.

AA7EE's Beautiful Sproutie MK II

 

This is almost too much.  Sensory overload is a real risk here.  Go check out AA7EE's amazingly beautiful regen receiver.  On his site he has a masterpiece of a write up, along  with schematics and build photos.  I love the plug-in toroids.    Great work Dave.  Thanks for sharing this with the homebrew community.

Alan Re-Caps His Drake 2-B

That Drake 2-B is a beautiful thing.   Every time I look at an older tube rig I'm reminded of the three dimensionality of these old machines.   Solid-state rigs are in Flatland, but tube rigs are in three dimensions.

Alan makes a very cool use of the I-pad in this repair.  And I'm jealous of his Hayseed Hamfest Electrolytic (I opted for the multiple caps hanging below the chassis).  Excellent management of the solder-sucker by Alan.  And I was impressed by the disciplined way he pulls solder from the reel -- he has the reel right next tot he rig and dispenses it directly.  I tend to hack off small lengths of solder and end up with lots of little bits of solder on the bench. 

Glad to hear that the other caps on the Drake are standing the test of time.  I wish the same could be said for all the caps in my Heath HW-101.

One thing caught my eye in Alan's video:  The dial cord.   You know you have become a true 2-B aficionado when you have actually gotten good at replacing the dial cord.  It is something of a rite of passage.   Perhaps this will serve as the basis for a future video by W2AEW,

Thanks Alan!  And congrats on passing 4 MILLION YouTube views.  People watch because your videos are so good.

Inspiring Stuff on "QSO Today"

Eric 4Z1UG is doing some really great interviews on his "QSO Today" podcast.   I found the last three to be especially informative and inspirational.

Chuck Adams K7QO dispensed a lot of useful information about Muppet boards and construction techniques, but more importantly he put out a lot of wisdom about the hobby, especially on the importance of teaching and sharing knowledge.

The interview with Glenn Elmore N6GN presented many interesting technical ideas, including using WSPR on VHF and UHF, and using aircraft reflections as a Sporadic-E like propagation mode.  He also mentioned "wing vortex" propagation.  Glenn talked about how to use a drone and a special light-weight transmission line to get your VHF/UHF (or cell phone) antenna above the trees.  (See above).

I found the conversation with Gerald Youngblood K5SDR both fascinating and a bit worrisome.  Gerald is obviously a great guy, and he does a wonderful job of describing the technology behind SDR radios, linking it to the phasing techniques that hams have been using since the dawn of single sideband.  He makes a strong case for the new SDR rigs, noting the absence of receiver-produced noise, the advantage of band-wide visual waterfall displays (even while noting that they tend to "make every ham an Official Observer"), and "brick wall filters that don't ring."  But I got and uneasy feeling when he referred to non-SDR rigs as "legacy rigs."  I found myself wondering how long it will be before all our rigs are required to be noise-less and all our filters skirt-less. Will there come a time when our beloved legacy rigs will be deemed unacceptable? (You can already hear this sentiment on the bands.)  And how much room is there in this SDR world for the kind of homebrewing we do? ( I know, I know.  I admit to feeling the presence of Ned Lud as I type these words.)

Great job Eric! And thanks to all the interviewees.   We look forward to the interview with Pete N6QW.

Claude Shannon had The Knack (video)

From Wikipedia:
Shannon showed an inclination towards mechanical and electrical things. His best subjects were science and mathematics, and at home he constructed such devices as models of planes, a radio-controlled model boat and a wireless telegraph system to a friend's house a half-mile away. While growing up, he also worked as a messenger for the Western Union company.
His childhood hero was Thomas Edison, whom he later learned was a distant cousin. Both were descendants of John Ogden (1609–1682), a colonial leader and an ancestor of many distinguished people. 

*************

And he he was part of a scheme to beat Vegas at the roulette wheel through the use of what may have been the first wearable computer: 
http://www.engadget.com/2013/09/18/edward-thorp-father-of-wearable-computing/

An excerpt from that site: 

After their initial meeting, Thorp says, "we got right to it," and he spent about half his time for the next eight months working away with Shannon in that basement lab in Shannon's house, on one of Massachusetts' Mystic Lakes. In his paper, Thorp described the lab as a "gadgeteer's paradise," with what he estimated to be about a hundred thousand dollars' worth of electronic, electrical and mechanical items. The regulation roulette wheel, ordered from Reno for $1,500, was set up on an old slate billiard table.

Thorp describes Shannon as the "ultimate gadgeteer," and recalled in his paper that the man he met in that office was a "thinnish alert man of middle height and build, somewhat sharp-featured," and that "his eyes had a genial crinkle and the brows suggested puckish incisive humor." That humor would become evident as the two worked together at the house on the lake. Thorp wrote that Shannon taught him to juggle three balls, and that he rode a unicycle on a steel cable strung between two tree stumps. "He later reached his goal," he wrote, "which was to juggle the balls while riding the unicycle on the tightrope."

Kids Homebrewing in Japan in the 1920s

 

Michael Rainey, AA1TJ, Poet Laureate of QRP and Wizard of the Vermont Hobbit Hole found this drawing and put it on his face book page.  It is clearly supportive of the "International Brotherhood of Electronic Wizards" theme of this blog, so I have shamelessly expropriated it.  All for the cause Michael!   I hope this indicates that OM AA1TJ is emerging from a too-long spate of radio-inactivity. 

 

Michael says the drawing is from the 1920's children’s magazine, "Kodomo No Kuni" by Kiichi Okamoto.  David Cowhig, WA1LBP, provides this translation:

 

Title "Ni-chan,  I can hear it!"

The radio kid is saying something like:

-- Wait, no I lost it.

-- uhhhh

-- I can hear it, I can hear it, I've got it!

 

David notes: Sometimes Japanese use the katakana syllabary to add emphasis like we might with italics or exclamation points.

Kon-Tiki and the Gibson Girl

Back in July we shared a very nice video sent to us by Rupert G6HVY on the radios used by the Kon-Tiki expedition.  Many of us had questions about the device used by the intrepid radio operator to generate hydrogen gas (for the antenna balloon) while on the high seas.   Mike Herr WA6ARA supplied the answer:   1200 grams of Calcium Hydride crystals.  This was part of the WWII rescue  radio set CRT-3 (aka the Gibson Girl). 

Fair Radio Sales occasionally sells this intriguing device:

And here is great site with more details on the other antenna supports in the Gibson Girl set, including a ROCKET LAUNCHED KITE!
