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:
Those of you following the Kenwood TS-990 will be happy to know that Kenwood has finally published an official press release with specifications and other details.
They are announcing a suggested retail price of ¥798,000, or $9,138.78 US as of day of posting. They offer the same price for the TS-990S (200 Watts) or the TS-990D (50 Watts-Japan only).
Kenwood has publicized a launch date of February 2013.
For those of you, like me, who got their start in ham radio by listening to international broadcasters on the shortwaves, you might like the article I just posted on the SWLing Post.
It’s a tour of the Edward R. Murrow Transmitting Station in Greenville, North Carolina. Formerly known as VOA Site B, this IBB transmitting station has a global reach and a dedicated team keeping her running each and every day.
The article was published earlier this year in The Monitoring Times magazine. Since there was no worries with page space, I was able to include even more hi-res color photos in my blog post.
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???)

Merry Christmas and Happy Holidays to all!
And now, what we’ve all been waiting for: the Ten-Tec Argonaut VI has finally hit the market. Manufacturer Ten-Tec has already begun shipping the new units–I hear they’ve already sold out the first production run. For the past two months, I have had the pleasure of beta-testing this newest QRP transceiver, and I’m ready to share my findings. [Do please note that, other than beta-testing, I have no relationship with Ten-Tec.]
I authored a post about the Model 539 when Ten-Tec first disclosed it at their 2011 Hamfest. The reactions and questions from readers came flooding in–so many, in fact, that I invited readers to send in those questions to share with the engineers at Ten-Tec. I presented these to the company, and posted Ten-Tec’s helpful responses.
In truth, I don’t think that Ten-Tec was quite prepared for all of the interest in their modest QRP transceiver. But it was no surprise to me: I’ve always been a fan of Ten-Tec, and although I’ve not been as excited by the QRP offerings since the early Argonauts, I knew I wasn’t alone in my appreciation of this US-based radio company’s quality products.
The following review is not a test-bench review–it is, rather, a consideration of the usability, ergonomics, design, basic performance and, well, fun factor of the new Argonaut VI. It’s only fair to note that I don’t review transceivers often; rather, I focus primarily on receiver reviews at my alternate radio blog. But I could not resist the opportunity to investigate the newest in this venerable line of transceivers.
You will note that I compare the Argonaut VI to the Elecraft K2 a number of times. Why? In my opinion, the K2 is the Argonaut VI’s closest competitor. It, too, is a front-panel QRP transceiver not for general coverage. While there are a number of differences, of course, I nonetheless feel the K2 is a closer match than the new Elecraft KX3, the Yaesu FT-817, or the Icom IC-703. Plus, I have a K2 that I already know and love here in my shack, so by default it has been my point of comparison throughout the beta-testing period.
Argonaut VI: first impressions
The Argonaut VI is an attractive, simple, sturdy little radio. It reminds me a great deal of the Ten-Tec Scout outfitted with its simple front panel. The front features two knobs: one controls the AF gain, while its outer ring controls RF gain; the other controls the bandwidth, while its outer ring controls the pass band. There is also an appropriately-sized display panel, quality tuning knob (see below), four multi-function buttons, and a three-position toggle switch.
A toggle switch? I can’t think of a recent front-panel radio in production that has had a proper mechanical toggle switch. On the Argo VI, this makes for a simple method to give the four function buttons a total of three one-push functions, each, for a total of twelve functions. Ten-Tec refers to this switch as the “TMB” (i.e., “Top-Middle-Bottom”) switch.
Size-wise, the Argonaut VI is smaller in every dimension than the K2 (see photos). Its physical dimensions are 2.25″H x 6.5″W x 7.6″D, less the knobs and connectors. It weighs a mere 3.6 lbs, and feels very light in my hands. The Argo VI has a sturdy Ten-Tec bail that snaps into the perfect position for tabletop operations. The display is crisp and clear, and actually contains a lot of information:
The display can be switched (via an internal setting) to blue (default), green, or red. One nice touch: the dot in the Ten-Tec logo is actually a red LED that lights up on transmit and ALC peaks.
Perhaps I place more emphasis on a tuning knob that other hams. I liken it to shutting the door on a quality car: you want the door to shut solidly and feel substantial. But it may be more like a car’s steering wheel–after all, the tuning knob is how one interacts with the radio. To me, the tuning knob is often a measure of a radio’s overall quality, in my humble opinion. As for the Argonaut VI? Here’s the answer: I was so impressed with the tuning knob on the Argonaut VI that I actually confirmed with Ten-Tec that the beta-unit’s tuning knob would also be used on production models. In short, the Argo VI’s tuning knob is heavy, perfectly-sized, has a light tactile grip, and is silky-smooth to operate. There is no play whatsoever in the action. I like the adaptive tuning, too–when you tune slowly, you’re changing the frequency by hundredths of a kHz; spin the knob quickly and you’ve just shot across the band. After tuning the Argo VI for a bit, other small radios’ tuning knobs begin to feel cheap.
When I first played with the Argo VI at the Ten-Tec hamfest, I was impressed with the simplicity of the front panel. This is an important factor because I simply won’t use a radio that isn’t pleasant to use/control, and I find that too many front buttons and general visual fussiness can be a distraction. To illustrate my point, when the Yaesu FT-817 hit the market over a decade ago, I was among the first to purchase one. I liked the idea of a small transceiver that I could tuck in my carry-on and take with me as I traveled. But I ended up selling the FT-817, however, because I hated the ergonomics and multi-function buttons. Button spacing was too tight for my larger hands, important multi-functions seemed to overlap, and menus were buried too deep for convenient operation. The FT-817 had a profound impact on all other buying decisions I’ve made since, and taught me that too much can simply be…too much.
Happily, on the Argo VI the most often used transceiver functions have dedicated buttons/knobs, and the display includes everything I need. Clean, clear, straightforward–this rig provides a pleasant operating experience.
For basic operations like rag-chewing, scanning the band, switching modes, switching bands, adjusting RF/AF/BW and PBT, you’ll be pleased, too. None of these operations require calling multi-functions or toggling the TMB switch (assuming you’re already in the “M” position).
But after spending some time on the air, I realized that there is a bit of a learning curve you’ll have to overcome before front-panel operations become entirely fluid and intuitive. To change RIT, you need to toggle the TMB switch to “B”, then press the RIT (BAN) button to toggle RIT on and off. If you hear DX working split, you’ll need to move the TMB switch to the “T” position, then set the A/B and SPL buttons; if you need to change modes or turn on the pre-amp, then you’ll have to move TMB back to “M.”
In the first few hours of testing the Argo VI, I found it easy to forget that I had the TMB switch set to a certain position when pressing a multi-function button, thus I was sometimes not receiving the response I expected. Several times I intended to change the band, but had the TMB set to “T” and resultingly opened the output power setting, or pressed the MOD button only to find that TMB was set to “T” as I toggled A/B VFOs.
While this was distracting at first, I soon became accustomed to changing the setting, then moving the TMB back to the “M” setting afterward. Now I find I very rarely make a mistake.
On the Argo VI, all of the buttons and knobs are adequately spaced. You could operate this rig outside with lightweight insulated gloves on, should the need arise.
All in all, the ergonomics are excellent on the Argonaut VI.
Before I begin talking about this little transceiver’s performance, I want to point out its two most obvious shortcomings:
If those two negatives are deal-breakers for you, I could certainly understand. You might want to consider a basic KX3 with ATU ($1070 unassembled, $1170 assembled) or a K2/10 with ATU ($1280 unassembled), instead.
But if, like me, you use neither 12 nor 60 meters very often, you may not miss them. Admittedly, the lack of 12 meters is unfortunate because it’s such an ideal band–when conditions are right–for easy QRP field operation. However, I am very pleased the Argo VI has 160 meters.
An internal ATU–or the option to have one installed later–is certainly a negative for those of us who like a simple Field Day radio set-up. From my point of view, other than my Elecraft KX1, I’ve never had a radio with an internal ATU; I have two portable tuners (the LDG Z11 Pro and Elecraft T1) that work wonders. The way my shack is designed, I have a remote auto-tuner outside at the feed point of my antennas and thus have no tuner in my shack–so if I had an internal ATU, I’d have to turn it off 95% of the time. If your shack is set up similarly, you might not mind not having an ATU.
If you’re concerned about the performance of the Argonaut VI, let me assure you now: you will not be disappointed. Indeed, the receiver in the Argonaut VI must be one of the best I’ve ever heard in any radio—especially in this price class ($1000). It is truly remarkable. I’m eager to learn how Rob Sherwood rates the Argonaut VI, but I suspect it will rank among the top few.
What is most impressive in the Argo VI is its incredibly effective variable DSP filtering. I experimented with the variable bandwidth and pass band during crowded CW conditions, and found that each and every time I could zero in on one QSO and block everything else. It’s also highly effective when used with SSB. Based on the reviews I’ve read of the Eagle, this is obviously derived from its DSP architecture and has similar performance characteristics. [Future Argo VI owners, I eagerly welcome A/B comparisons of the Eagle and Argo VI–please comment!]
You’ll be happy with both the Argo’s sensitivity and its ability to reject adjacent signals. Compared with my Elecraft K2/10, the Argo VI’s sensitivity had an edge in every band I tested, and to my ear, the noise floor is lower on the Argo VI as well. Most noticeably, however, is the Argonaut’s audio fidelity, which is far superior to that of the K2. Whether using headphones or using the built-in top mounted speaker, you will be pleased. The speaker delivers an impressive sound for its size. I tend to hook up external speakers to my smaller transceivers, but in this case I never felt I needed to. With headphones, the audio is even more impressive. I do wish the headphone jack was on the front panel instead of the back, though.
Though I haven’t spent enough time with the KX3 to compare audio fidelity, I imagine the KX3 and Argonaut VI would be a fair contest.
I can say that audio fidelity is the primary reason I continue to turn to Ten-Tec for transceivers and receivers. In my opinion, like Kenwood, Ten-Tec invests more resources into insuring superb audio fidelity–even at the cost (in this case) of uber-low current drain numbers (although the 550 mA drain on receive must be the lowest Ten-Tec has ever produced in a digital transceiver). The Argo VI’s audio is rich, inviting enjoyable listening for hours on end. It would certainly be a great pick for long-haul events like Field Day or 24/48-hour contests.
But how does she sound on the other end? Immediately after unpacking the Argonaut VI, I caught band openings on 10, 15, 17 and 20 meters. Though I was only running 7 watts at the time (production units run a full 10W) I received great audio reports on SSB and was even heard through a pile-up on 17M. Though I believe the default settings would have worked well, setting up the mic gain on this rig is also very easy and straightforward.
As for CW, reports have also been very positive. CW ops will be happy to note that the Argonaut VI has Ten-Tec’s silky-smooth QSK. Frankly, I expected nothing less.
Since I don’t operate digital modes often, I did not test the Argo VI in this capacity. I imagine reviews will emerge soon, but I expect them to be positive as several beta testers were impressed.
When I begin a radio review, I keep a checklist of pros and cons as I discover them to remind myself of my initial discoveries. Here’s my list from the Argonaut VI:
To buy, or not to buy…
I really think the Argonaut VI is a streamlined Ten-Tec Eagle, and a very good rig. Its DSP architecture is based on the Eagle’s (in beta, we even used the Eagle software for the frequent firmware updates).
When I ask myself, “Who will buy the Argonaut VI?” I believe the answer is anyone who wants a QRP radio with the performance and interface we’ve come to expect from Ten-Tec. If you can live without 12 and 60 meters, then you will be buying a rig that does not compromise on performance. The Argonaut VI is not a QRP radio designed for backpacking like the KX1 or KX3, but it would hang with the best in a QRP contest or on Field Day; operators would experience little to no listening fatigue with this smooth rig.
The Argo VI comes factory-assembled, warrantied, and ready to go, right out of the box. There’s nothing to put together nor configure.
On a side note, I should mention that this is the first time I’ve beta-tested with Ten-Tec; this provided insight into the process of rolling out a new product and just how responsive and open the company is to both frank criticism and design requests. I believe all of the beta-testers would agree. Every concern I reported to Ten-Tec was eventually addressed by version 1.0 of the firmware. That’s responsiveness I can really appreciate. Ten-Tec’s Software Engineer, John Henry, is nothing short of amazing. I’m not sure when he finds the time to sleep.
I’m happy to have had this little radio in my shack for the past two months. I’ll have to bid it farewell, though: Ten-Tec has already sold out of their first production run, so my unit will be returned, upgraded with a new board, tested, inspected, and sold as a demo. Alas, it’s hard to say good-bye.
I guess the proof is in the Christmas pudding: I have to admit that I now prefer the Argonaut VI even over my trusty Elecraft K2. So, kind readers, if one of you is in the market for a K2/10 with SSB, and 160M, I may be in the market for an Argonaut VI.
It would bring tidings of great joy, indeed. Happy holidays!
When the band is open, 10 meters is the band for QRP DXing–great DX can be worked with very low power and very modest antennas.
The entire world congregates on 10 meters on the second full weekend of December for the ARRL 10 Meter Contest. This year this contest falls on the weekend of December 8-9, 2012. Complete rules can be found here: www.arrl.org/10-meter. It is worthwhile to note that this contest allows participation by both CW and phone operators.
We are approaching the peak of sunspot cycle 24 and conditions on 10 meters should be excellent for working DX. Even those not interested in the contest per se should take advantage of the propagation and the sheer numbers of DX stations on the band to work some “new ones”.
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.
Winter is the time to operate on 160-meters. Within the next six weeks we find not one, not two, but three 160-meter contests.
November 29, 2012 (0000-0600 UTC ): QRP ARCI Top Band Sprint (rules) — note that this the evening of Wednesday, November 28 in North America!
November 30 – December 2, 2012 (2200 UTC Friday – 1600 UTC Sunday): ARRL 160 Meter Contest (rules); this contest includes a QRP class.
December 29 – 30 (1500 UTC Saturday – 1500 UTC Sunday): Stew Perry Top Band Distance Challenge (rules); this contest includes a QRP class.
If you don’t have a dedicated 160-meter antenna but have a 40m or 80m dipole/doublet, try shorting the feedline at the radio and work it against ground through an antenna tuner; this will convert your dipole/doublet into a vertical with a really big “top hat”.
