SolomonSea SolderSmoke

As further evidence of the global reach of SolderSmoke, David, M0VTG, recently took the book all the way to Papua New Guinea. The picture above was taken aboard the Barbarian II while in the Solomon Sea. Eppa (on the right) is giving the book a thumbs up (but he doesn't seem quite sure about it). Thanks David! Thanks Eppa!

New Overhead Photo of Apollo 11 Site

The Lunar Reconnaissance Orbiter recently took this shot of Tranquillity Base. This was from 30 miles (50 km) up. Very cool.

No Smoke, but stars, an HW-8, and one (dead) Cinghiale!

No podcast today -- we were out in the country. As you can see from the picture above, the question of just how big the Sabina wild boars really are has been answered. The one pictured above was shot today very close to our country place (neither Billy nor Maria did the shooting!) The hunters tell us that this one was considered a big one. As you can see, it is about the size of Billy.

I had the telescope out this weekend -- we were looking at the moon, Jupiter, Mars, and the Orion nebula. Also watched a satellite going over shortly before dawn. And one meteor.

I was on the air a bit, on the CQ WW DX contest. Worked about six stations. Was on 40, 20, and 15 with the HW-8.

I will try to get SS 119 out as soon as I can. I hope all you turkey eaters had a good holiday.

Electronics Animations

Oh man, this the kind of thing that makes my hand-drawn diagrams seem even more inadequate. If this is the new standard, I'm in trouble! Jim, K9JM, sent this to us. Thanks Jim.

50 stations receive my 20 mW DSB Ubuntu WSPR signals

In less than a week of intermittent WSPR operations with the new Ubuntu WSPR 2.0, 50 stations have received my awesome 20 mW Double Sideband HB WSPR signal. (Am I still the only station in the world running WSPR DSB?) 49 of the stations have been in Europe. The only across-the-pond report comes from W1XP. Only once was my signal above the noise level -- that was with a neighbor, Andrea, IW0HK. Above you can see the screenshot of his reception of my signal.

You Linux-masters out there might be able to help me with a couple of things: WSPR 2.0 seems to stop running if I leave it alone for a few hours (maybe it opposes un-attended beacon operations!) And I also have what I think is an un-related problem: The computer (a Tecra 8100) goes into some sort of deep sleep mode (a coma really) if I leave it alone for a few more hours. I've tried playing with all the Ubuntu power managment and screen-save settings. And I've gone back into the bios and the set-up section on the computer to change the sleep modes, etc. No luck.

Happy Thanksgiving to all our American readers! We will be having turkey with all the fixings here in Rome today.

Harry Gets His Own Domain

You know a guy has made a real impact when all you need is his first name. Harry, SM0VPO aka G4VVJ is in that category. His web site has been a source of circuits, ideas, and inspiration for many years now. For his 2009 birthday, he got his own domain. Visit the site: http://www.sm0vpo.com

On Top Band at Age 12 and 1/4!

Gil sent me a link to the wonderful site of W8JI. The OM got his start by removing plates from the tuning cap of an All-American 5 broadcast receiver. Heart warming stuff for knack victims. Be sure to visit his Boatanchor page -- check out his DX-60. Doesn't that rig look a little bit TOO good? Are those regulation knobs? Or have they been juiced up a bit? (Mine don't sparkle quite so much.)

"Industrial Revolution 2" Tinkering Gets Respectable

Bruce, KK0S, alerted me to this wonderful article in the Wall Street Journal. I liked the line about the "hackerspaces" being "like gyms, but with people milling iron, not pumping it."

WSPRing with Ubuntu

Wow, the radio gods are are really helping me lately! Soon after receiving my new Ubuntu laptop, Joe Taylor, K1JT, released the first Linux version of his amazing WSPR program. And he wrote it for the version of Linux that I am using: Ubuntu!
Not only that, the new version includes a feature that I was most in need of: the capability of handling compound call signs. No longer am I signing on from Rome as N2CQR -- now the all-important I0/ is also displayed (see the above map). I had very little trouble getting Ubuntu WSPR running on my machine (and as you all know, I am a real Linux klutz). The new program also allows for periodic CW identification. Very cool. Here something I noticed: WSPR requires the computer clock to be accurately calibrated. With my old Windows machine I had to periodically tweak the clock using an on-line GMT clock. But when I went to check the accuracy of the clock in the Ubuntu machine, it was EXACTLY right. To the second. I wonder if Ubuntu Linux has a feature that automatically synchs the computer clock with GMT.
Here is what Joe says about the new software:
-----------------------------

WSPR 2.0 is now available for download from the WSJT Home Page, http://physics.princeton.edu/pulsar/K1JT/
Click on WSPR in the left margin, then on the appropriate WSPR 2.0 link for your operating system. Installable binary packages are provided for Windows and for recent Debian-based 32-bit Linux systems. A recommended Linux distribution is Ubuntu 9.04.

Version 2.0 of WSPR introduces a number of new program features, including the following:

- User-friendly setup screen with drop-down selection of audio devices and CAT parameters
- Support for compound callsigns
- Fine adjustment of fractional time for transmitting
- Optional CW identification
- Tools for frequency calibration and automated frequency corrections for your radio
- A Tune button
- Direct on-line access to the WSPR 2.0 User's guide, WSPRnet, and the WSJT Home Page

Full details are presented in the all-new User's Guide, which is a "must read" if you want to use the new features. The manual includes a Troubleshooting guide. Click http://physics.princeton.edu/pulsar/K1JT/WSPR_2.0_User.pdf to read the manual.

Three cheers for Joe Taylor!

Radio, Douglas MacArthur, and staying young at heart

Art, KG6ZWD, sent this along. General MacArthur kept this poem displayed above his desk in Manila, and frequently quoted from it during his time in Tokyo. The radio part comes near the end.

Youth

By Samuel Ullman

Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

Youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease. This often exists in a man of sixty more than a boy of twenty. Nobody grows old merely by a number of years. We grow old by deserting our ideals.

Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.

Whether sixty or sixteen, there is in every human being’s heart the lure of wonder, the unfailing child-like appetite of what’s next, and the joy of the game of living. In the center of your heart and my heart there is a wireless station; so long as it receives messages of beauty, hope, cheer, courage and power from men and from the infinite, so long are you young.

When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old, even at twenty, but as long as your aerials are up, to catch the waves of optimism, there is hope you may die young at eighty.

An amazing radio history book - FREE!

Robert, WP4PQV, sent us some links to a treasure trove of U.S. Navy electronics publications that have been placed on-line. My initial perusal of the collection took me to History of Communications in the U.S. Navy by Capt. Howeth. Here is one gem from this amazing book:

Emperor Tiberius ruled Rome from the island of Capri for 10 years, around 37 A.D., transmitting his orders by means of the heliograph.³ This indicates that the Romans, at this time, used some form of telegraphic code in the transmission of information.

"From Atoms to Amperes" by F.A. Wilson

From Atoms to Amperes by F. A. Wilson
Published in 1989, Bernard Babani Publishing LTD (London, The Grampians, Shepherds Bush Road, London, W6 7NF)

I love this book. Mine is now held together by duct tape and crazy glue. Doug, WB5TKI, reports spotting a copy on sale on Amazon for $50 (go for it!). Here is a question for our British readers: Who is F.A. Wilson? There is almost nothing about him on the web, other than references to this and other similarly brilliant technical books. He was writing in the 1980s and 90s. What a great knack he has for explaining this stuff.
---------------------------------------------
First sentence: We are not physicists whose mission in life is to dig deeply into the mysteries of the universe but people wishing to know something about what makes electricity tick.

Explains in crystal clear terms the absolute fundamentals behind electricity and electronics. Really helps you to discover and understand the subject, perhaps for the first time ever.

Have you ever:

• Wondered about the true link between electricity and magnetism? • Felt you could never understand the work of Einstein, Newton, Boltzmann, Planck and other early scientists? • Just accepted that an electron is like a little black ball? • Got mixed up with e.m.f. and p.d. ? • Thought the idea of holes in semiconductors is a bit much?

Then Help is at hand with this inexpensive book, in as simple a way as possible and without too much complex mathmematics and formulae.
