MAKE'S "Do More With Less" Contest

This from the MAKE blog this morning:

To promote the release of the Windows Phone 7, Microsoft is partnering with various websites, including MAKE, to give away a Windows Phone 7 to each site's readership. To be eligible, all you have to do is post a comment on the theme of "Do more with less" ...


Wow! This contest seems to be MADE for the G-QRP gang! (What is it? "It is vain to use more..." Something like that!) I think G3RJV could win this one!

This is all related to a quote from Buckminster Fuller, hence the image of the very cool stamp.

See the International Space Station THIS WEEK!

Spaceweather.com showed this beautiful picture of an International Space Station fly-over. It was taken by David Blanchard near Flagstaff, Arizona on Saturday.

The space station will be visible from much of North America in the evening this week. Spaceweather.com has a very handy calculator that will let you know when and where to look. Just plug in your zip code:

(There is a global version of the calculator for users outside the U.S.)

Let's see how many SolderSmoke readers get to see the ISS this week. Please let me know if you see it.

W4HBK's QRSS Grabber: The Amazing Pensacola Snapper

When we were in Italy, ON5EX provided my "go to" grabber. Because we were just one ionospheric hop away, and because Johan had a really excellent receive system, it seemed like my little signals were visible on his screen from dawn to dusk every day.

Now that we are back in the States, W4HBK's grabber is playing a similar role for me. His grabber consistently seems to pull in more sigs than most of the other North American grabbers. The above image is a sample of what you will see when you visit his grabber web page. (I'm also a big fan of the W1BW and VE1VDM grabbers -- thanks guys!)

My signal is the "shark-fin" pattern just a little below the middle of the screen. That's 20 mw to a 50 foot piece of AC line cord about 12 feet off the ground. And it is making the trip from Northern Virginia to Pensacola Florida very consistently. Thanks Bill!

Try taking a look at the Pensacola Snapper and see if you can spot my QRSS signal. My frequency varies from day-to-day (sometimes intentionally!). And lately Bill has occasionally been parking his receiver on 40 meters :-( But most days you will be able to see his 30 meter screen, with my shark fins menacing Pensacola. Please let me know if you see me.

Here is OM HBK and his bio:
Born: 1939, Pensacola, Florida

I was first licensed in 1954 as WN4HBK and upgraded to General in 1955 acquiring the call sign I've used to this day. My dad is responsible for my favorite suffix moniker. the Hot Biscuit Kid. I could really put away my mom's scratch biscuits!

My first station I built myself and consisted of super regenerative RX and a 6L6 TX.from designs in the ARRL Handbook. My dad was a radio mechanic for the Navy and taught me how to read schematics and solder. Later stations consisted of Hallicrafters S-38C, National NC-98, HRO-5 recievers and several Heathkit and Globe Scout transmitters. Boy, those were the days!!

After high school I entered college intending to become an antenna engineer but eventually gravitated towards a degree in Physics. This was pretty cool because it led to a career with NASA where I worked on the Mercury, Gemini, Apollo and Space Shuttle projectsall thanks to my early interest in radio.

Today I'm fully retired and living in Gulf Breeze, FL. just across Pensacola Bay from my hometown. My XYL (Anna) and I enjoy the local beaches in a variety of wayssurf fishing, beachcombing, hiking, painting (her) and photography (me). We are also enjoy gardening and winemaking.

My Amateur Radio interests are CW, DX, contests, antennas and digital modes.

Presently I am experimenting with QRSS and have a 250 milliwatt MEPT station on 10.140 MHzsend me an email if you copy my signal. I now have a grabber to present a spectral display of QRSS activity for other Hams worldwide to watch for their signals http://www.qsl.net/w4hbk/w4hbkgrabber.html

The Hacker-Knacker-Maker Revolution gathers steam...

I got a bit of mail from Great Britain about the use of the word "knackers" in yesterday's post. I vaguely remembered that this word has anatomical connotations in the UK. But it just worked so well. I needed something that would rhyme with Marx's "Workers." And "Knackers" is kind of close to "Hackers." And we all have "The Knack." So, I made use of some artistic license. Apologies to our British cousins. I'm already on linguistic thin ice with them because of my use of the American pronunciation of solder. (The Brits pronounce the L -- to their ears, the American pronunciation conjures up an activity far removed from soldering.)

Anyway, the Hack-Knack-Make revolution continues. This morning I learned that the New York and Philadelphia Hacker-spaces will be featured on NPR's Weekend Edition this Sunday. (I'm jealous -- I want SolderSmoke to somehow get onto NPR. One listener suggested a letter-writing campaign...)

The poster shown above is for a documentary that is being done on all of this. Check it out:

KNACKERS OF THE WORLD UNITE! You have nothing to lose but your warranties!

The folks over at ifixit.com have come up with a Self-Repair Manifesto that readers of this blog will find inspirational. I like the line about "Repair injects soul and makes things unique!" Indeed. As of yesterday they were giving away free posters (real posters, not e-posters) in exchange for a Tweet (I got mine, and intend to put it up here in the SolderSmoke Shack.)

I find that a successful repair is almost as gratifying as a scratch-built homebrew project, especially if the problem was difficult to diagnose.

So, ifixit comrades: The SolderSmoke collective is with you! Up the Revolution!

"She built her own oscilloscope at age 14." Homebrew Hero: Tatjana Van Vark

AJ8T sent me the link to the web site of this, our latest Homebrew Hero. I don't think she is a ham, but Tatjana definitely has The Knack. Check out that workmanship. The range of the projects is also quite astounding. It is so impressive that I really found myself questioning whether this could be for real. But it is.

When you look at the Enigma-like coding machine, note the cryptological challenge at the bottom. Tatjana won't release the tech details of this project until someone cracks the encrypted Haiku! Go for it!

Homebrew Transistors!



None of those store-bought parts for Jeri Ellsworth! Once again she makes us all look like a bunch of pathetic appliance operators. I like the "harvesting of Germanium" from a 1N34. And I found very interesting her comment about "early hobbyists" cracking open 1N34's and turning them into transistors by adding phosphor-bronze collectors.

This all makes me want to fire up my Fool's Gold crystal radio. WFAX is right down the road...

BTW: I'm very pleased to report that Jeri is currently reading "SolderSmoke -- Global Adventures in Wireless Electronics." I hope she likes it. She definitely has "The Knack."

SolderSmoke Podcast 127 is almost ready.

Back on the air with QRSS QRPp

I dusted off the old G0UPL QRSS QRPP FSK 30 meter transmitter (built and last used in Italy) and hooked it up to about 50 feet of AC line cord stretched low across the new Northern Virginia backyard. I hooked it up to my Kempton Park power supply (thanks for the chip Tony!) and fired up my freq counter (also from Kempton Park -- remember the chip I soldered in backwards?) I put a field strength meter next to the wire and tuned my L network for max smoke. Hey, and it worked! My signal is the wavy shark fin-looking thing. I think the wave results from a temp drop in the shack that happened when I opened the door. Just to confirm it was me, I turned the transmitter off for a few minutes. You can see me disappear from W1BW's screen.

Its good to be once again emitting EM waves!

Linux makes you younger! "Aha! moments"

Listeners seem to like the audio quality of SolderSmoke episode #126. I was surprised by this because I didn't do any of the post-recording processing that I'd done in earlier episodes. I didn't even have the foam "Popping P Protector" on the mic. And the equalizer that Brent sent hasn't been put in service yet. The improved audio may simply be the result of broader bandwidth -- I didn't use the Audacity equalizer to drop off the lows and highs. Perhaps that explains why the file was over 40 MB instead of the normal 20 MB. Several listeners said that I sounded 10 years younger in 126 -- it must be a Linux thing.

Chris KJ4GUU posted a nice comment about my book "SolderSmoke -- Global Adventures in Wireless Electronics" (which he calls SSGAWE):

"I have started reading I have started reading SSGAWE again. Whenever I have a question about a project I can usually find help in your book, its becoming more of a cherished reference guide that has produced more Ah-ha! moments than any other book I own. Thanks again!"

Thanks Chris -- those "Ah-ha! moments" were what I was hoping to produce.

RSS, Time Signal, Miners...

I was very pleased to send SolderSmoke 126 out yesterday. There are some bugs to be worked out. The audio -- as always -- could use some improvement. (Any comments on how the audio in 126 compares with the 120-125?)

I tried to update the RSS feed this morning -- please let me know if it works properly.

Several listeners have already identified the time Spanish language time signal I've been hearing on 75 meters: HD2IOA in Guayaquil, Ecuador.

Great to see the Chilean miners coming up out of the mine this morning!

Update, Columbus Day


OK, the Drake 2-B is running. I'm listening to 75 meter SSB. Coffee is on. Solder has been melted in the new shack -- I had to replace the MPF-102 in my little DaVinci Code beacon MEPT 30 meter transmitter. Little by little, SolderSmoke HQ is coming back together, this time in Northern Virginia.

SolderSmokeStatus

I've been getting some increasingly desperate messages about SolderSmoke withdrawal symptoms so I thought I'd better send out a status report. Also, one listener wrote in addressing me as "The Grand Poobah of the SolderSmoke Brotherhood." Wow, with a title like that, I better get going with the podcasts!

Most of the stuff is in the shack. The workbench is assembled. I'm trying to set up for both 220 and 110 (lots of Euro gear accumulated over the last ten years!) Surprisingly, Home Depot doesn't sell 110 to 220 transformers. And I live in an area where LOTS of people move back and forth across the pond. I may have to press my old autotransformer into service.

Most of my really old gear -- the stuff that went into storage over the last decade -- should show up in a week or so. This means my HT-37, DX-40, DX-60, Lafayette HA-600 etc. will be reappearing on the scene.

I hope to get some beacons (uh, I mean MEPTs!) on the air soon.

Unfortunately my ancient computer gave up the ghost during the trip. Hard drive is making scary noises. This will slow down the podcast as I have trouble putting it together with Linux only (which is what I'm operating with now -- thanks Jorge! Without your help I'd be completely off the net) Anyone have any version of Windows I could legally use?

But the Drake 2-B is doing fine. I'm listening to 75 SSB as I type.

Hang in there loyal listeners. Perhaps some of that nicotine gum would help. Or, better, some REAL solder smoke.

Climbing a REALLY tall tower

No thanks, I think I'll stick to tree-supported dipoles.

Thanks to Brent, KD0GLS for sending along this really scary video.

Getting Settled -- Slowly. Yogi Berra on Theory and Practice

I've been getting some "Are you alive?" inquiries from SolderSmoke fans. I'm happy to report that, yes, I am still around, and doing fairly well. This move back to the states has been a bit more difficult and complicated than previous transfers, but slowly the shack is starting to come
together. Moat important: The Drake 2-B survived the journey!

It may take me a few weeks to start emitting whistling S sounds and Gong noises ("Wow, that's awesome!') but hang in there, new SolderSmoke episodes are on the way.

Meanwhile, I wanted to share with you a Yogi Berra quote sent to me by Brent, KD0GLS. I think this is especially appropriate because my grandfather actually played for the New York Yankees:

"As I make my way through the back episodes of SolderSmoke at a stately pace and hear you speak of Bletchley Park, I'm also reading "Secrets & Lies" by Bruce Schneier, renowned cryptographer and internet security expert. In his book, I read this timeless quote that immediately made me think of our hobby:

"In theory there is no difference between theory and practice. In practice there is."
Yogi Berra"

Thanks Brent! Thanks Yogi!
