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.
[…]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.”
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.
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:
One of the many hams profiled in Max Cooper’s article: Carl Smith (N4AA), publisher of The DX Magazine (Photo: Mountain Xpress)
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.”
Today, I watched a fascinating eleven-minute NASA animation depicting key events of NASA’s newest Mars rover, Curiosity, in action.
Does this pattern remind you of something? Yep, the letter “L”. The other tires produce a “J” and “P” on the Martian surface. (Photo: NASA/JPL)
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.
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.
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…
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.
I’ve been meaning to write a post about my Elecraft KX1, because, of all of the rigs I own, it’s the most-often-used, thus the clear favorite in my stable. But: this morning, I read John Harper’s (AE5X) excellent assessment of the Elecraft KX1 vs. the Ten-Tec HB1B. He provides some significant numbers to consider when comparing these two lightweight CW-only QRP rigs, and makes a great case for elevating the newcomer HB1B over the KX1–at least, for some readers.
I’ve had my Elecraft KX1 for over three years, and, in all honesty, absolutely love it. But, let’s face it: if I didn’t have one, if I had never touched nor used one, I would be seriously tempted by the HB1B–for its price, for the fact that Ten-Tec sells it (I’m a long-time Sevierville radio fan), and for the fact that it’s not a kit. Oh, yeah: and because it works very well.
However, having used the KX1 for so long, I know that the HB1B (at least in its current state) could not replace my KX1. But before I explain why, I would like to make some strong points in favor of the HB1B.
The Ten-Tec HB1B
The Ten-Tec HB1B
At least on paper, the HB1B has better filtering, a better display, and generally speaking, more bells and whistles than the KX1. Best of all, it comes fully assembled.
Why is this last point an advantage–? For a number of talented QRPers reading this, building the kit is the best part! I know, I get it…And to tell the truth, I want to be like you kit-builders out there! But I am only now getting into kit building, and building my confidence in kit-building. I’m sure there are many others out there like me. For these QRPers, please note: the KX1 is not a beginner’s kit. I did not build mine. When I bought my KX1, I purchased it from a KX1 beta tester and professional engineer. The soldering and overall build quality are top-shelf.
Moreover, no matter how great an Elecraft radio is, it’s only as good as the person who built it. If the builder does sloppy work, your rig’s longevity and performance may suffer. Since you’ll likely be taking the KX1 with you everywhere, and it’ll experience a fair amount of movement (aka, hard knocks), this is especially important.
If, like me, you’re not prepared to take on building a KX1, fear not!–you should simply purchase from someone who knows their stuff: Elecraft can suggest some builders (including the amazing Don Wilhelm, W3FPR) or you can simply purchased a used KX1 fully-assembled. Or, you can simply purchase the fully-assembled HB1B.
So, why do I not find the HB1B enticing?
Yes, the Ten-Tec HB1B comes ready to roll. Still, could it replace my KX1? I don’t think so. Two HB1B deal-breakers for me:
As AE5X mentions, there is no internal antenna tuner option.
There is no way (at least, on this version) to attach paddles directly to the rig.
Portability + Simplicity = QRP Fun
Why are these features so important? Well, my KX1 has an ATU, four bands, and an attachable paddle. One of my favorite things to do with my KX1 is, while traveling, to pull it out of its Pelican case, toss a 28′ wire into a tree, and lay a ground wire. As I stand there, I can hold the KX1, tune the antenna (easily 40M and up, with the internal ATU) and work stations my favorite way: while standing up. I can also (if I like) sit for a moment, then jump up again, walk a bit, and generally move freely–just not possible with sit-on-a-table units.
My Elecraft KX1 fits nicely inside the Pelican 1060 case. There's even room to fit an external Whiterock paddle.
Additionally, everything I need fits inside a Pelican 1060 case. The Kx1 itself is an all-in-one unit–nothing external to attach, unless I want to. Oh, and I can also operate the KX1 with gloves on in below-zero conditions.
Anywhere QRP
Why would I want to operate standing up? Fact is, where I go, I’m only operating for thirty minutes or so, and in places where there’s no convenient spot to settle down or get too comfortable. In many cases, I’m operating on a whim–when I can grab a few minutes in a busy itinerary, or on a hike or day trip. With the Kx1, this is remarkably easy to do. I can have my KX1 on the air in four minutes or less, in most cases–and that includes the time to hang a wire–! Packing up is also quick. This kind of operation feels as free as flying a kite. Spontaneity at its best.
Part of that functional synergy comes from the fact that there are no additional components to hook up (i.e., no external tuner, external paddles). With the HB1B, I would be forced to either build a set-up, so that I could stand and hold the transceiver, tuner and paddles, or I’d have to…sit down.
Wayne’s inspiration for the KX1
Thinking back to a Dayton Hamvention several years ago, I seemed to remember that Wayne Burdick, N6KR (co-founder of Elecraft) was inspired by just this sort of off-the-cuff operation. To confirm this, I asked Wayne, just this morning, if I was on track with that. He offered this very thorough (and insightful) response:
I had been designing portable QRP gear for my own use for many years, including the “Safari 4″ (documented in three issues of QEX magazine in 1990). The Safari-4 was 3x5x7”, but it was fully self-contained, including an attached keyer paddle, internal 1-Ahr gel cell and manual antenna tuner, wattmeter, SWR bridge, and 4-band coverage. But it was too large for backpacking. Later, I designed some far smaller rigs with very good performance for NorCal and Wilderness Radio, including the SST, NC40A, and Sierra.
Then I started Elecraft with Eric, WA6HHQ. After we had success with the K2 and K1, I pitched the idea of a smaller version of the Safari-4 to Eric.
There were two inspirations for this. Back in the 70s, W7ZOI (Wes) created his “Mountaineer”, which was a crystal-controlled 40-m QRP rig that was very simple to use, very small, and self-contained, in that battery and paddles were built in. But it had no VFO, no ATU, a single band, and no frills. Taking what we’d learned in the K2 and K1 designs, I figured we could pack a great radio into this same size using updated technology. It had to cover at least 40 and 20 meters, and the idea was to use latching relays to minimize current drain and simplify band switching. We also used a DDS chip for the VFO–not quite as pure as crystal control, but just as stable, and totally adequate for a portable radio.
The other inspiration was my idea for an attached, but easily removable and mechanically reversible, keyer paddle. This became the KXPD1. I literally woke up at 5 AM with this idea. I realized immediately that this was the enabling technology for a hand-held radio, and I got busy with the design.
Having spent time camping and hiking with other rigs, I also knew that the ATU had to be built in. This allows the use of ad-hoc, wire-in-a-tree antennas, which is the secret to quick setup. It was a challenge creating an ATU that’s just 1 x 5″, but it worked. We spent weeks refining the rig and the ATU to work with typical field antennas, adjusting the component values to cover 40 and 20 meters. When we added the 30-m module, we found that it handled this well, too.
Most of my KX1 operation involves not even sitting down. I literally stop on the trail at a scenic overlook, pull the daypack around and extract the rig, toss a wire into one or two trees, and I’m on the air. I love this kind of operation. I’ve gone so far as to operate while sitting in a tree (an “inverted vertical”–a dangling wire–works amazingly well). Having to futz with add-ons can be fun, too, but it discourages “instant” operation. I like to quote Ade Weiss, W0RSP, from his book The Joy of QRP: “If there is a place, and you can get to it, you must operate from there.”
You can’t overlook performance and features, either. The KX1 is stable in all operating environments and draws only about 35 mA. It includes a variable-passband crystal filter that can be widened out to copy AM and SSB signals, and can even do cross-mode (transmitting in CW while receiving LSB or USB). It has a full set of frequency memories and CW message buffers. For blind hams (or when you’re too tired to keep your eyes open), the KX1 has a 100% Morse-audio-feedback system. I tested this firmware with my eyes closed, and the result was very well-received by the blind amateur community.
Thanks for the history, and your inspiration, Wayne. Love it!
The KX1's Tuning, RF, AF and Filter knobs are very easy to operate--even with gloves on!
When you hold and operate the KX1, this legacy is all too apparent. Thoroughly thought through–down to a built-in LED lamp for logging–and, without a doubt, the original inspiration for several radios that followed: the HB1B, the MFJ 92XX series, and the Hendricks PFR3.
My guess is that the next generation of HB1B will have some of these clever features.
In the meantime, if you’re in the market for an inexpensive, CW-only, very portable QRP rig, and you’ve no plans to embark upon impromptu operation, the HB1B could be your rig. Based on my experience with Ten-Tec, if they sell it, they’ll give you excellent customer service. That is the beauty of these two choices, both Elecraft and Ten-Tec are excellent companies to do business with.
I only think I’d give up my KX1 for…the new KX3, and I’m not even convinced I’d do that, yet. The KX1 has become my little travel buddy. Time will tell, though. Check back here–if I’m wooed by another QRP radio, I may eat my words.
By the way, as I mentioned at the beginning of this post, the inspiration to finally write down my thoughts on the KX1 came from John Harper (AE5X) who has an excellent QRP blog that you should certainly add to your favorites! And thanks, again, to Wayne, both for his response, and for his original ideas that continue to make QRP so liberating.
Once upon a time I’d decided to join a Big Guns Gang and made a Super-Duper Powerful Vacuum Tube QRP amplifier for my 800mW QRPP homebrew telegraph vacuum tube transceiver “3T” (I promise to write a separate article or two about this three tube transceiver project later). It was not an easy decision to me because for that legendary time I’d almost a year used the QRPPpower of less than a watt[…]
