More QRPoetry from AA1TJ

This is actually prose, not verse, but it has a poetic element to it. It is not for nothing that we have called Michael "the poet laureate of QRP." Must be all that time up on the mountain. Whatever the motivation, we're always happy to get his messages, and we always find inspiration in them:

On the topic of QRP power levels; for me it all stems from the pair of "100mW" walkie-talkies that my brother and I found under the Christmas tree one year. I thought it was magical that we could walk around the neighborhood and still talk to each other. Then one day my friend and I was messing around and I heard some lady's (CBer) voice all of a sudden. It took a moment to figure out that she was talking to me (my first and last CB QSO). We only talked for a few moments but it left me wondering how far it might be possible to communicate with such low power. The electronics magazines I was just starting to read showed massive boat-anchor transmitters; none of which appealed to me. For me the excitement was trying to see how far I could talk with my MPF102 oscillator on 40m; and later, a similar xmtr made from a surplus 2N697 that I happened upon. It was around that time I first heard about tunnel diodes; exotic devices based upon the (still) mystical notion of quantum tunnelling. Of course, I dreamed about building a tunnel diode rig...a dream that would take 35 years to realize...to which I owe a huge debt to Seab, AA1MY...dunno if he knows to this day how big of a deal it was for me; which is why I was especially happy to see his, "with childlike joy and wonder" comment. Ditto for me. Speaking of which, last I showed my wife, N4KGL/p's QTH on the map located on his site "Nov 23rd Lunch Time QRP". http://www.n4kgl.info/ We thought it was fun to progressively zoom out from the parking lot where he was operating yesterday. Right away the Gulf of Mexico appears. Of course, Vermont eventually comes into view. Scientific American that did a similar series of zooms in a book some years ago. It began with a couple lying on a blanket in a park. Some pages later you're staring back at this "pale blue dot" (to steal Carl Sagan's wonderful phrase). Something else comes to mind from Tom Wolfe's, The Right Stuff. Do you recall the passage where Lovell covers the Earth with his thumb? "At one point I sighted the earth with my thumb—and my thumb from that distance fit over the entire planet. I realized how insignificant we all are if everything I'd ever known is behind my thumb. But at that moment I don't think the three of us understood the lasting significance of what we were looking at." Dunno why, but QRPp feels a bit like Lovell's thumb. It gives me the same sense of vertigo displacement; a tiny signal sent from a tiny man located in a vast, oceanic, Universe. I remember saying so to my pal, Jim, W1PID, only last year in connection to my voice-powered CW transmitter. Hearing the dits and dahs return yesterday...looking at my puny transmitter...Wisconsin, Florida, Guadeloupe Island; bouncing these little ripples off the ionosphere...hearing the friendly replies...who would not be overwhelmed by the thought of it all? These little radios are just the launchers; pinkie fingers dabbed in the cosmic pool of Being. The Argentinian writer, Antonio Porchia, said, "Beyond my body my veins are invisible." Jim Lovell's veins radiated from beneath the thumb he so casually dabbed over the Earth. His veins radiated not just back to far away Earth - to everything that he loved - but in all directions; to places he'd never even dreamed of. I'd better sign now. I'm headed up to the mountain-top TV transmitter in a couple of hours... That's how it is here, Steve; QRO pays the bills, QRPp gives the thrills. :o) BTW, Dave, K1SWL, has already given a big thumbs-up to our RockMite contact! 73/72, Mike, AA1TJ

SARA: The Society of Amateur Radio Astronomers

My recent experience listening to live on-line meteor pings led me to the web site of an organization that I used to belong to: SARA: The Society of Amateur Radio Astronomers. Knack to the max in this bunch. These people are going for the REAL DX! Check out their site:

Forrest Mims on amateur science

Here's another dose of inspiration from one of our "Homebrew Heroes." Forrest Mims has been one of my heroes for a long time. A colleague yesterday gave me a copy of a recent article in Make about his ozone measuring device (build at home with Radio Shack parts!). With this device he was able to outshine NASA in the data accuracy department. Check out the article:

AJ4VD Solves the Barcode Mystery

The QRSS world was recently mystified by the sudden appearance of this monster on the European grabber screens. People quickly realized that it was a "QR barcode" -- kind of a souped-up version of the standard barcodes, this version holding more information. But what was the message? Scott Harden, AJ4VD, got on the case, and solved the mystery. Read about it here:

Scott is a very interesting fellow, and surely one of the younger "Knights of the QRSS." Check out his bio page: http://www.swharden.com/blog/?page_id=344
Bravo Scott!

More from Kitty Hawk

Kitty Hawk N.C., Thanksgiving 2010. Wright Brother's test site. The big rock marks the take-off point. You can see a reproduction of the monorail they used in lieu of landing gear. the white markers behind me show the distances covered on those first four flights. Off in the distance you can see the final, longest flight of that day: 852 feet. 59 seconds aloft.

Thanksgiving at Kitty Hawk

We spent a very pleasant Thanksgiving day with family out on the Outer Banks of North Carolina, in Kitty Hawk. Of course, we visited the site 0f the Wright Brother's famous first flight. I'll have more about this in the next SolderSmoke podcast. For now, let me share with you this interesting quote about the importance of play and toys (from Wikipedia):

"In 1878 their father, who travelled often as a bishop in the Church of the United Brethren in Christ, brought home a toy "helicopter" for his two younger sons. The device was based on an invention of French aeronautical pioneer Alphonse Pénaud. Made of paper, bamboo and cork with a rubber band to twirl its rotor, it was about a foot long. Wilbur and Orville played with it until it broke, and then built their own. In later years, they pointed to their experience with the toy as the initial spark of their interest in flying."

SolderSmoke in Botswana!

Frosty, K5LBU, sent us this report from Botswana:

I just completed reading your book tonight. I had taken it with me on the Dxpedition to Botswana and while there Jay W5SL read it and enjoyed it very much. But what was so great in his reading it was to see a good friend of mine mentioned in your book. He was there with us and having a great time working the pileups. This person was none other than Gianfranco I0ZY. I have visited with him at his office and operated his great station in his home there in Rome. What a small world it is. I will be back in Rome to pick up a new Amplifier from Gianfranco. 73' Charles Frost Frosty K5LBU

We had a blog post about Gianfranco and his amplifiers last year. Check it out here:

Jupiter's Moons Utility

"Sky and Telescope" has a nice collection of on-line astronomy utilities. One of my favorites displays the positions of Jupiter's Galilean moons. It also gives you some nice heads up on the transit and eclipses of the moons. Its fun to play with the "+10 minute" button and see how they move around. The view you see above is fairly close to what I see through my telescope (but Jupiter's stripes are not quite so pronounced). You can get the utility for free -- you just have to fill out a registration form.

N8ZRY's Homebrew SSB Rig

A while back we had post about amateur RADAR. The wizard behind that project was Greg, N8ZRY. (I liked his quote: "Old radars do not die... they simply phase array.") Greg's latest project is the 20 meter SSB rig pictured above. It was recently featured on the Make blog.
Check it out here. Be sure to look at the YouTube video. Nice job Greg!
