CQ columnist Fred Maia, W5YI, a leading amateur radio journalist, educator and pioneer of volunteer examining, passed away on March 28 after a battle with cancer.
Maia, 76, published “The W5YI Report,” dubbed “America’s Oldest Ham Radio Newsletter,” from 1978 to 2003, and has been a CQ contributing editor since 1985. His regulatory affairs column, first titled “Ticket Talk,” then “Washington Readout,” offered news and perspective on FCC and ITU (International Telecommunication Union) actions, and helped untold numbers of hams wend their way through often-confusing mazes of the volunteer examining and vanity call sign systems.

The Four State QRP Group is pleased to announce a new kit, the QRPometer, a sensitive and accurate power/swr meter designed by David Cripe, NMØS. Complete specifications, assembly manual, and ordering information can be found here ttp://www.wa0itp.com/qrpom.html
PayPal is accepted.
The range of accurate power easurement extends down to a low 100 milliwatts. This kit was conceived to fill a need within the hobby for an inexpensive, highly accurate RF power and VSWR meter for QRP power levels. With it’s large digital display it makes a very useful addition to your shack.
The QRPometer uses simple analog signal-processing circuitry to provide a set of essential measurement features not previously available in a single unit. High quality, double sided,
printed circuit board construction is used, with solder mask and silk screened component reference designators.
All components are through-hole for easy assembly. NO toroids are required, and all controls and jacks are PCB mounted. The QRPometer can be constructed by beginners as well as experienced builders. Construction time is approximately 3 hours, depending on experience level. The only equipment required for calibration is a digital voltmeter, and a QRP transmitter..
All proceeds go to fund OzarkCon. As always, thank you for supporting the Four State QRP Group. http://www.4sqrp.com/
UPDATE: See comments–first run of these kits sold out within 27 hours! More to come later.
OzarkCon is a fun and informative QRP conference held every year in Branson, Missouri. This year, the conference is being held at the Stone Castle Hotel and Conference Center on April 13 and 14th. Registration and room rates are very reasonable.
I would like to announce that the complete collection of QRPp, the NorCal QRP Club Journal that I did from 1993 to 2004 is now on line. Chuck Adams has scanned in every page of every issue and has it on line at http://www.k7qo.net/NorCal_QRPp.html. This is a temporary site, as we want to make sure that all of the bugs are out of it before we place it on the NorCal page where it will have a permanent home in about 3 weeks. This material is for the education of QRPers, and it will always be free. No one will ever have to pay anything to access it. We ask that no one makes it available on CD for distribution in any way. Everyone is granted permission to make an archival copy, but no one is granted permission to post any part or portion online. We want there to be one site where it is available. Some of the schematics will be redrawn and Chuck is coordinating that effort. I have struggled for years on how to make the information available and decided that this is the way to do it. Every article was donated, no one was paid anything for writing any article. So, I wanted to make it available for free. Enjoy. Thank you to Chuck Adams for doing the work to make the pdf’s, to Dean Davis for his future work in putting it on the NorCal web page, and especially to all of the contributors over the years. 72, Doug, KI6DS
Even the Wall Street Journal picked up on the latest solar flare–the biggest in 5 years–which is headed towards Earth:
WASHINGTON—The largest solar flare in five years is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and airplane flights.[…]
“It’s hitting us right in the nose,” said Joe Kunches, a scientist for the National Oceanic and Atmospheric Administration. He called it the sun’s version of “Super Tuesday.”
The solar storm is likely to last through Friday morning, but the region that erupted can still send more blasts our way, Mr. Kunches said. He said another set of active sunspots is ready to aim at Earth right after this.
But for now, scientists are waiting to see what happens Thursday when the charged particles hit Earth at four million mph. [Continue reading at the WSJ]
GEOMAGNETIC STORM UPDATE: A CME propelled toward Earth by this morning’s X5-class solar flare is expected to reach our planet on March 8th at 0625 UT (+/- 7 hr). Analysts at the Goddard Space Weather Lab, who prepared the CME’s forecast track, say the impact could spark a strong-to-severe geomagnetic storm.
Expect some major geomagnetic disturbances and don’t be surprised if the HF bands are very quiet while we’re being blasted with electrons. On the plus side? If you live in Northern latitudes, look for some awe-inspiring auroras in the night sky.

If you visit Google’s home page today, you’ll notice that their typical logo has been replaced with an animation of an undulating, multi-colored wave.
If you click on the wave, you’ll be taken to sites telling the story of Heinrich Rudolf Hertz.
We should all take a moment today to thank Hertz for his contribution to the radio spectrum. Indeed, it was Hertz who showed that electricity could be transmitted via electromagnetic waves. This laid the groundwork for developing wireless telegraph and radio. In the 1930’s the International Electrotechnical Commission decided that Hertz’s name would become the unit of frequency for our electromagnetic spectrum–the hertz (Hz)–about four decades after the his death.

Ten-Tec's John Henry behind prototype of the Ten-Tec Model 539 QRP Transceiver at the 2011 Ten-Tec Hamfest
Several of you have written in asking me about updates on the status of the Model 539 and Model 418 from Ten-Tec. I asked Ten-Tec Software Engineer, John Henry, for an update. Here is his response:
Hi Tom,
We have ordered and are building what we think will be representative of the final production boards for the 539. We may have one more board spin for one or two boards, but hardware wise I believe we are in pretty good shape. Software, we are still in development of the firmware for the rig, but we are making real good progress. Timing, not sure yet, but it is in process along with several other new items.
Regarding the 418, we have two more tweaks to the firmware to make. The hardware is finished, and being released to production. We are ordering parts, and plan to be at least taking orders around mid May, if not shipping by then. We passed the testing for FCC, and are in the process of getting the paperwork through FCC. We had a lot of positive input on the 418 at Orlando Hamcation, so we expect the 418 to be a hit with QRPers that also want to use their QRP rig to go 100watts occasionally.
It’s official — delegates attending the 2012 World Radiocommunication Conference (WRC-12) have approved a new 7-kilohertz-wide secondary allocation between 472-479 kHz for the Amateur Radio Service. Agenda Item 1.23 had both its first and second readings in Plenary Session on Tuesday, February 14; to become part of the ITU’s Radio Regulations, each Agenda Item must be read twice in Plenary Session. The new allocation will become official on Friday, February 17 at the close of the Conference.
“This is a fantastic achievement for the Amateur Radio Service,” IARU President Tim Ellam. VE6SH, told the ARRL. “A new allocation for spectrum is always something that should be celebrated. The success on this issue is due to the hard work over the last four years from our IARU representatives, as well as the volunteers from the numerous IARU Member-Societies who have worked within the ITU process on behalf of their national administrations. This is excellent work from our team in Geneva, and from those who have assisted from their home countries.”
Agenda Item 1.23 originally called for a 15-kilohertz-wide spectrum in parts of the band 415-526.5 kHz, taking into account the need to protect existing services. But according to ARRL Chief Executive Officer David Sumner, K1ZZ, this was in conflict with the Maritime Mobile Service. WRC-12 delegates approved Agenda Item 1.10, which called for a worldwide exclusive allocation to the Maritime Mobile Service of 495-505 kHz. Discussion of this allocation to Maritime Mobile “has been in the works throughout the conference preparation (i.e. since 2008),” Sumner explained, “and was the reason why the MF amateur allocation could not be made in this band as some amateurs had hoped. That’s why we had to look elsewhere and is what put us in conflict with aeronautical radionavigation.”
According to Colin Thomas, G3PSM, CEPT Coordinator for Agenda Item 1.23, WRC-12 delegates moved forward early in the Conference with what he called a “compromise proposal” for the new allocation. “Progress was made with a compromise proposal on Agenda Item 1.23, drafted to take into consideration the views of those for and those against an Amateur Service allocation around 500 kHz. This proposal suggests a 7-kilohertz segment between 472-479 kHz, very close to the CEPT position of 472-480 kHz.”
The new allocation calls for a worldwide secondary allocation to the Amateur Service at 472-479 kHz, with a power limit of 1 W EIRP. A provision has been made, however, for administrations to permit up to 5 W EIRP for stations located more than 800 km from certain countries that wish to protect their aeronautical radionavigation service (non-directional beacons) from any possible interference. Footnotes (see below) provide administrations with opportunities to “opt out” of the amateur allocation and/or to upgrade their aeronautical radionavigation service to primary, if they wish to do so. In addition to these protections for aeronautical radionavigation, the Amateur Service must avoid harmful interference to the primary maritime mobile service. Quite a few additional administrations — mainly in the former Soviet Union and the Arab states — added their country’s names to the Footnotes prior to the Agenda Item’s consideration in Plenary.
More than 3000 participants — representing more than 150 out of the International Telecommunication Union’s 193 Member States — are attending the four-week conference. About 100 Observers from among the ITU’s 700 private sector members — along with international organizations, including the International Amateur Radio Union — are also in attendance. A number of WRC-12 delegates are radio amateurs, with many of them operating at 4U1ITU, the Amateur Radio station at ITU Headquarters. The station has been using the call sign 4U1WRC throughout the duration of the Conference. [Continue reading…]
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.
When you first glance at the title, Ham Radio USA – 100 Years and Counting, you can’t help but think out loud and ask yourself when ham radio had its real start. If ham radio in the USA really is to have its centennial celebration this year, that necessarily means that we’re assigning the year 1912 a great deal of significance. For the purposes of this article, we’ll focus on the formative years of ham radio and leave the modern for another discussion at another time.
[…]No doubt there are many of us who have been asked regarding the origin of the word “ham,” a word which has come to define our hobby. Although you may not take this as the final word on the subject, you will find this particular interpretation interesting, as there would seem to be no reason to doubt its authenticity. The word ham actually appears in the publication “The Telegraphist” in September of 1884 when referring to a not so good telegrapher as a “duffer” or “ham.” The word “duffer” may be defined as an incompetent or clumsy person, one with little professional training or experience. Although today we take great pride in being called a ham in 2012, being called a ham, at least in the context mentioned here, was unflattering and derogatory at best, during the day of the land line telegrapher of 1884 per this particular citation.
