And I thought my buddy, Mike (K8RAT), was being gastronomically adventurous when he made a homemade single-lever “sideswiper” with a steak knife! Imagine what might happen if the steak knife meets up with this:

CW on the pirate bands
Last night, I captured the pirate radio station Dit Dah Radio on 6,935 kHz (+/-) USB. I published the audio on my shortwave radio blog, The SWLing Post, where I post quite a lot of shortwave radio recordings.
I’m well aware that no law-abiding ham radio operator would ever broadcast as a pirate radio station. So this must be a non-ham, right? (OK, fess up!!! Who was it???)
You’ll especially like their CW preamble (or, interval signal, I suppose) which they follow with The Capris’ 1960’s hit, Morse Code of Love. Click here to download, or listen in the embedded player below:
Merry Christmas and Happy Holidays to all!
A Few Hours in the ARRL 160 Meter Contest
I was able to spend about three hours participating in the ARRL 160 Meter Contest this past weekend. I operated CW-only, using my Elecraft K2 running 5-watts, and my primary antenna was my low 195′ Inverted-L tuned with an LDG Z-11 QRP autotuner.
I concentrated on working new sections but even so managed to make 72 QSOs with stations in 30 sections; this translated into an hourly rate of about 24 QSOs per hour–not bad for QRP into a compromise antenna. I worked stations in the states shown in the map below, plus Ontario. (My station is located in southeastern Ohio.)
Although my primary antenna was my Inverted-L, I also shorted the feedline of my windowline-fed 135′ doublet at the tuner and fed the antenna against ground; this antenna allowed me to make one QSO I couldn’t make with the Inverted-L.
I had been hoping to work a DX station or two and heard but wasn’t able to work just one non-US, non-Canadian station, a station in the Bahamas.

Dot
Dash
Dot
Dash
This is the moon as Morse code.
[…]All over the world, ham radio operators and Morse Code enthusiasts beam dot, dash messages straight at the moon, then wait 2.7 seconds for the signal to bounce back. They call these “E.M.E.” transmissions, which stands for “Earth-Moon-Earth” or — more popularly — “moonbouncing.” I suppose it’s fun to smack little beeps against a sleepy rock 239,000 miles away and have those beeps come flying back at you. Plus, it’s easy.
[…]Not so long ago, a Scottish artist, Katie Paterson, turned Beethoven’s Moonlight Sonata into Morse code, (yup, you can do that, too) and bounced it off the moon. Some musical phrases got trapped in moon craters and didn’t come back, which she found so intriguing, she put the ricocheted, fragmented Moonlight Sonata on a player piano and you can now see her MoonBounced, Morse-Coded piece being not performed by anyone, the keys going up and down on their own, on YouTube.
I’m a huge fan of Krulwich’s witty science articles and am thoroughly impressed that he brings CW into the popular press. Nevermind his tongue-in-cheek!
PS: As I wrote Robert, I think Artemis would love to hear the “sacred language.”
Upcoming Event — 2012 QRP ARCI Fall QSO Party
This coming weekend is the 2012 QRP ARCI Fall QSO Party, one of the most popular contests of the QRP calendar. This year, new entry categories are based on the antenna used; those participating with a simple wire antenna or a vertical won’t be competing against those using beams or other multi-element antennas.
The Fall QSO Party runs from 1200UTC on Saturday the 13th through 2400UTC on Sunday the 14th.
Here are the complete rules:

I won’t be competing in the Fall QSO Party to win. Instead, I’ll do as I’ve done several times in the past–I’ll use this event as an opportunity for what might be my last outdoor “field event” of the year. A good friend and I will be spending a few hours at Mt. Gilead State Park in north-central Ohio enjoying what promises to be beautiful fall weather, good friendship, and an opportunity to enjoy CW in the great outdoors.
If you participate in the Fall QSO Party, you are very likely to hear stations participating in the Pennsylvania and Arizona QSO Parties. Here are the rules for these two events:

Mountain Xpress: Your cellphone can’t do this
I’m very proud of our local free community newspaper, the Mountain Xpress for its article on ham radio. Not only does the article give readership a short primer in the hobby, but it also profiles a variety of local hams–even an 18 year old YL.
This one is worth a read and goes beyond the boiler-plate local articles that usually follow on the heals of Field Day. I’ve included a few clips below:

On a stifling late-June day, a tangle of wires snakes through the open door of the Buncombe County Firefighters’ Training Center. Outside, the sun beats down and the roar of big generators fills the air; indoors, the atmosphere is even thicker, dense with a jarring concoction of radio static, Morse code and urgent voices.
[…]At first glance, the whole endeavor seems anachronistic. In an age of global communication, pervasive cell coverage and hundred-million-member social networks, what’s the attraction of basic, point-to-point radio communication? Who are these people who call each other not by name but by arcane strings of characters? What exactly are they doing?
[…]That fear may be unfounded: Today’s ubiquitous tech appears to be re-energizing the long-standing hobby. Pioneering operators have merged radio (an analog medium) with digital communication, and the Internet gives beginners a broad base of support.
“Amateur radio is very much alive and well,” says Bill Morine (N2COP), North Carolina section manager for the Relay League. “An awful lot of young people are coming out and seeing the merger of technologies between computers and wireless applications.”Nationwide, there are 700,000 licensed hams — an all-time high, he reports. The licensing process is easy, Morine maintains, and ham radio’s staid image is no longer accurate.
[…]Carl Smith (N4AA) represents the old guard. Licensed in 1954 at age 14, the Air Force veteran and retired electronics salesman has logged more than 70,000 radio contacts, many from his home in Leicester. In ham circles, he’s a big deal: For the past 15 years, he’s published The DX Magazine, a bimonthly journal for serious hams with long-range ambitions.
[…]For some operators, service is ham radio’s primary purpose, and dropping the code requirement has unquestionably attracted many younger licensees. Eighteen-year-old Virginia Todd (KK4BRE), for example, got involved due to radio’s community-service opportunities and usefulness in emergencies.
“We volunteer a lot,” she says. “We did the bike race for Meals on Wheels and the Shut-In Trail Ridge Run.”
Paul Tilley (KK4BRD) says ham radio is just another communications tool he uses as a SKYWARN spotter. In foul weather, Tilley takes to the road in a truck equipped with a rooftop weather station, using his radio to report conditions to the National Weather Service. In remote areas lacking cell coverage, Tilley’s radio has enabled him to give people in the path of a storm time to prepare.
“There are storms that make it past the mountains that don’t appear on the radar at all,” Tilley explains. He’s had some close calls, including a lightning strike that destroyed his radio, but he stresses that he’s not a storm chaser. “Storm chasing in the mountains is extremely dangerous: You can’t see the weather coming.”
Even the most obsessed hams make time for community-service work. When Smith isn’t chasing DX, he heads the Buncombe County Amateur Radio Emergency Service, whose roughly 25 volunteers assist emergency-response agencies when normal communications fail. Because radio requires no infrastructure, it’s often vital in large-scale emergencies.
[…]That’s why emergency power is paramount on Field Day. But though the underlying purpose is serious, the event is also a chance for these operators to have some fun.
Watching Smith work CW is a jaw-dropping experience, and he quickly draws a crowd. Even while talking to those around him, he transmits so fast that the individual dits and dahs are barely discernible. Outside, other hams set up antennas in preparation for an all-nighter.
“This is my favorite day of the year,” says Tonya Campbell (WB0VDK) in between transmissions.
And as night falls, Marc Huennekens (KG4OPM) sets up a station in a tent in the bed of his truck. Using an old, tube-driven radio, he plans to log as many contacts as he can before falling asleep.
Back in the training center, the room is thick with Smith’s rapid-fire code, open-band static and low voices swapping stories. One old-timer recalls how it feels to be hit by lightning — twice.
After 24 grueling hours, the club has logged nearly 1,000 contacts. Smith alone worked 300 stations, transmitting all night and into the next morning. The allure of ham radio, he explains, is equal parts technical endeavor, community service and fellowship.
“Through ham radio,” notes Smith, “I can go anywhere in the world and know somebody and have a friend. I daresay your cellphone can’t do that.”
Curiosity making tracks…with morse code?
Today, I watched a fascinating eleven-minute NASA animation depicting key events of NASA’s newest Mars rover, Curiosity, in action.
As I watched, I noticed something very peculiar about the tires–right around mark 5:15, one can see a pattern imprinted on them. At first I thought nothing of it, assuming NASA scientists had pondered the perfect pattern for traction and also shedding any trapped rocks or debris.
But–as my curiosity was piqued– a little research on the rover tires revealed this article from TyrePress.com: “Curiosity’s tyres ‘tagging’ Mars” in which the pattern is explained:
Yesterday the Mars Curiosity rover successfully went into action on the surface of the red planet, and the vehicle’s tyre tracks have gained a measure of notoriety. It turns out that Curiosity is ‘tagging’ the surface of Mars as it drives about.
A series of notches included in the track tyre tread is not just a pretty pattern – the notches are in fact Morse Code and spell out the letters ‘JPL’, short for NASA’s Jet Propulsion Laboratory. Curiosity is now busy leaving the laboratory’s initials all over Mars[;] however [this] is not just wanton interplanetary vandalism – the dots and dashes are part of the rover’s visual odometry system, used to estimate changes in position over time.
Brilliant! Not to mention, practical…NASA has just put morse code on the Mars surface!
Perhaps it proves that it’ll be very difficult to do away with morse code. At least, until NASA sends a sweeper or Zen garden raker-rover to Mars.
FITSAT-1 will write messages in the sky with CW
At first, I thought this news item was sience fiction, then I realized, “no, it’s just the coolest thing ever.”
Thanks for sharing, Eric!

The robotic Japanese cargo vessel now en route to the International Space Station is loaded with food, clothes, equipment — and a set of tiny amateur radio satellites, including one that will write Morse code messages in the sky.
[…]One of the [satellites], FITSAT-1, will write messages in the night sky with Morse code, helping researchers test out optical communication techniques for satellites, researchers said.
[…]One of FITSAT-1’s experimental duties is to twinkle as an artificial star, said project leader Takushi Tanaka, an FIT professor of computer science and engineering. Tanaka’s research interests include artificial intelligence, language processing, logic programming and robot soccer, in addition to cubesats.
Tipping the scales at just under 3 pounds (1.33 kilograms), FITSAT-1 carries high power light-emitting diodes (LEDs) that will produce extremely bright flashes.
“These, we hope, will be observable by the unaided eye or with small binoculars,” Tanaka says on a FITSAT-1 website.
After its deployment from the orbiting lab, the cubesat’s high-output LEDs will blink in flash mode, generating a Morse code beacon signal.
Video: Tuning the Ten-Tec Argonaut VI
As Ten-Tec was setting up at the Dayton Hamvention last Thursday, I was able to meet with their engineer (John Henry) briefly and had a little time to play with the new Model 539 Argonaut VI. As I tuned around the CW side of the 20 meter band, I recorded a short video. I’m sharing this with you here, but must ask your forgiveness for its quality and glitches; I want to make it clear that this material was recorded on my Android phone in some haste.
Moreover, this video does not do justice to the Argo VI’s audio, which is exceptional. In fact, I can’t tell a difference between its audio and that of the Ten-Tec Eagle, both of which have very low noise floors and simply gorgeous audio fidelity.
Now, just a small taste of what this receiver can do…
Gmail Tap: I only wish it were true….
Google has once again featured morse code–this time (unfortunately) as an April Fool’s joke! This video will explain it all, then, raise your hand if you’re disappointed.
