My new-to-me TEN-TEC Argonaut V

While browsing the QTH.com classifieds last weekend, I found an ad for a Ten-Tec Argonaut V (Model 516).

The Argo V was a general coverage HF transceiver produced by TEN-TEC starting around 2003 or so. When it was introduced to market, I wanted one because I thought not only would it be a great QRP transceiver, but TEN-TEC rigs tended to have brilliant audio and were capable broadcast band receivers.

The seller described it as being in “pristine condition and operating to factory specs on all bands.”

The seller seemed to be a nice fellow and sent me a number of photos with his QSL card in the image and his email address matched what was on file with QRZ.com. The seller checked out on many levels confirming this wasn’t a scam (always assume a classifieds listing could be a scam!).

I purchased it last week and it was delivered today.

The first thing I did after connecting it to a power supply was tune to the 31 meter band, switch the mode to AM, and widen the variable filter to 6 kHz (the Argo’s max AM bandwidth).

So far, I’m impressed!

For a ham radio transceiver, I can tell that the Argo V is going to be a competent rig for casual shortwave radio listening.

I also tuned to the mediumwave band (not having even checked in advance its lower RX limit) and am happy to report that it covers the whole AM BC band as well.

If I’m being honest, though, the real reason I’ve always wanted an Argonaut V, specifically, is because I absolutely love the front panel design of this radio.

The large LED digit frequency display is fabulous and has–as my buddy Eric put it–a certain “Apollo era” aesthetic. The large frequency display was one of my favorite things about my beloved OMNI VI+ as well.

I’ll admit that I also love a good analog meter!

The Argonaut V also has a very simple, very Ten-Tec, front panel with good field ergonomics. In fact, the Argo V is a very simple radio: there are no modern features like message memory keying, built-in batteries, nor does it have an internal ATU.

Although spec-wise, I’ve much better receivers at SWLing Post HQ, I’m looking forward traveling the shortwaves with the Argo V!

Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Significant X-class solar flare (Southgate ARC)

There was a global eruption on the sun today. It started with a powerful X1-class solar flare from sunspot AR2887.

The blast created a massive tsunami of plasma in the sun’s atmosphere, which rippled across the entire solar disk. A CME is probably heading for Earth, raising the possibility of a geomagnetic storm on Halloween. More information and updates @ Spaceweather.com.

History of the Ham Radio Callsign (Southgate ARC)

In this video Mike Ritz W7VO looks at the history of amateur radio call signs in the United States

Every legal amateur radio operator in the world has a unique callsign assigned to them by their government, and many of us are better known by our callsign than our given name. But what world event was it that caused these monikers to be? Why are they constructed the way they are? Continue reading →

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Skip Arey, Mike Hansgen, and David Iurescia for the following tips:

Nobody cares about DAB radio – so let’s force it onto smart speakers, suggests UK govt review (The Register)

Britain’s anti Amazon and Google war gets a second front

The UK may require smart speakers such as Amazon Echo and Google Home devices to broadcast UK DAB radio stations, over government fears that Brits aren’t consuming enough of the unloved radio tech.

Under the guise of “protecting UK radio stations’ accessibility” the Department for Culture, Media and Sport (DCMS) has published a report calling for smart speakers to rebroadcast domestic radio stations’ output. The recommendation is as follows:

The government to consider regulatory changes to ensure radio stations and radio and audio content can be easily found and is discoverable by users of voice assistant platforms, including smart speakers and in-car infotainment systems.

The call, made in the Ministry of Fun’s Digital Radio and Audio Review, was backed by national broadcaster the BBC and commercial radio groups.

The same report found that 64 per cent of audio on smart speakers is live radio, though smart speaker users make up around 6 per cent of radio listeners at present. Nonetheless, DCMS called for governmental action to enforce the provision of something that’s already provided.

Media minister Julia Lopez said in a canned statement: “We must make sure this treasured medium continues to reach audiences as listening shifts to new technologies and that we have a gradual transition away from FM to protect elderly listeners and those in remote areas.” [Continue reading…]

Interested in getting a U.S. Amateur Radio license? (David Sarnoff Radio Club)

Earlier this year, the IEEE Princeton / Central Jersey Section’s Broadcast Technology Chapter (IEEE PCJS BT) received a generous grant to provide mentoring and equipment that encourages understanding of digital and analog aspects of radio communication, through hands-on activities and explorations. Over the next 2 years, our Make Operating Radio Easier (MORE) Project will be training 500 new U.S. Amateur Radio (“Ham”) operators in small (10 to 15 person) groups. We are especially seeking youth (ages 12-18) and non-males to help increase the demographics for these underrepresented groups on the air, but are currently accepting applicants of all ages (12+) and all genders.

Class sessions are primarily virtual (via Zoom) but may be arranged to be on-site if there is sufficient interest by a school, club or organization (as allowed, given the ongoing health situation). Virtual or in-person FCC amateur license testing sessions will also be arranged (throughout the USA) by our ARRL-certified MORE Project Volunteer Examiner (VE) team. There is no charge for the classes, and ALL testing and licensing fees for participants in the MORE Project are covered by our grant. Trainees in our program will also receive (paid by the MORE Project) a Software Defined Radio USB dongle, a pre-assembled 25-foot longwire receiving antenna, and (after successfully licensing) a hand-held Yaesu 2 Meter (HT) radio. The MORE Project course will provide instruction in the use of this equipment and assistance in Getting On The Air (GOTA) to make radio contacts.

Additional information about the MORE Project, including how to register for a training course, is at n2re.org/m-o-r-e-project and in our IEEE PCJS Call for Participation flyer. Questions should be directed to Dr. Rebecca Mercuri K3RPM at [email protected].

RTI’s German-language special program garners thousands of responses (RTI)

During the third quarter of every year, Radio Taiwan International (RTI) broadcasts a special one-hour radio program via shortwave directly to German-speaking countries. The programs were transmitted over four weekends between July and August. Usually, RTI’s German programs are relayed through Bulgaria.

This year, thanks to conducive weather conditions and precise engineering, RTI’s signal was stronger than in prior years. In response to the program, listeners from 33 countries sent over a thousand reception reports confirming they received the broadcast. According to RTI, it received a record number of reports.

Radio Taiwan International President Chang Cheng says that even though most of the station’s programs are available online, there is still a significant community of people that prefers listening to shortwave radio.

This year, listeners who sent in a reception report for the special one-hour broadcast will receive a limited edition RTI QSL card featuring Taiwan’s iconic Formosan Blue Magpie. RTI says that it is still in the process of responding to all of the listening reports it received.

Jock’s radio-related book recommendations

Some radio-related books you might want to read

By Jock Elliott, KB2GOM

Radio-related books – books in which radio is not the main subject but plays a significant role in the storyline or plot (whether it is fiction or non-fiction) – can inspire us. Whether we are shortwave listeners, HF utilities monitors, or VHF/UHF scanner fans, radio-related books can heighten our appreciation of what we do, I think.

With that in mind, below are some radio-related books that I have read and can heartily recommend.

This Is Chance!: The Shaking of an All-American City, A Voice That Held It Together

In 1964, a 9.2 earthquake shook Anchorage, Alaska, with a ferocity not seen in North America before.

When the shaking stopped, night fell; the city went dark, and people began tuning their transistor radios to hear a familiar voice.

Genie Chance, a part-time reporter and working mother, would stay on the air almost continuously for the next three days as an eclectic group of officials and volunteers worked to begin picking up the pieces. This is a moving story about radio, ham radio (a bit), and people rallying together.

Ten Hours Until Dawn: The True Story of Heroism and Tragedy Aboard the Can Do

In 1978, in the midst of a blizzard, the tanker Global Hope floundered on the shoals in Salem Sound off the Massachusetts coast.

In response to Mayday calls, the Coast Guard dispatched a patrol boat. Within an hour, the Coast Guard boat lost its radar, depth finder, and engine power in horrendous seas.

Pilot boat Captain Frank Quirk was monitoring Coast Guard VHF radio and decided to act.

Read this book sitting by the fire, far from the sea. A chilling account.

The US Navy’s On-the-Roof Gang: Volume I – Prelude to War

Between WWI and WWII, the US Navy realized the need to intercept and decode Japanese military and diplomatic radio traffic.

Matt Zullo calls this book a novel because he had to fill in the blanks in some areas, but most of the book is based on official documentation and personal recollections.

It is a ripping good yarn, written in an engaging style, that spans the globe from Samoa to Greenland, and I found it fascinating and will soon be reading the second volume.

The Road Home

After an earthquake rips Seattle, Robbie and his father have to rely on their wits and some new-found skills to get home safely.

This fictional story includes many emergency preparedness and ham radio tips. Some are a bit dated, but many are still applicable today.

Well worth the reading.

The Day After

The sequel to The Road Home.

After learning that his neighbor Katy is injured, alone, and needs help, Robbie ventures out, and a short trip across the city will turn into a race for survival that cleverly illustrates useful emergency preparedness while emphasizing the importance of communication and thinking ahead.

Again, in my humble opinion well worth the time.

And now . . . it’s your turn!

What radio-related books – fiction or non-fiction — would you recommend? As a dyed-in-the-wool, unrepentant, not-on-the-12-step-program bookaholic, I’m always looking for a good read!

Ham Radio Workbench episode explores Diversity Reception

3 Replies

The SDRplay RSPduo

I just finished listening to the most recent episode of the Ham Radio Workbench with John Fallows (VE6EY) as a guest.

John is an SWL and Ham Radio operator and speaks at length about how he uses diversity reception to mitigate persistent local RFI (radio frequency interference).

If you have persistent issues with radio interference or if you’ve been curious about using diversity reception for mediumwave and shortwave DXing, I highly recommend listening to this episode. John has been known to frequent the SWLing Post and actually comes into the discussion primarily from an SWL’s perspective.

If you’ve tried diversity reception or a noise-cancelling system like the Timewave ANC-4+ in the past with mixed results, you’ll definitely benefit from listening to John’s best practices.

In addition, John points out that the excellent SDRplay RSPduo is a very affordable way to explore proper diversity reception.

How effectively can you mitigate RFI with diversity reception? Check out this video on YouTube queued up to the point where John does a live demo with his Anan SDR and loop antennas: https://youtu.be/vu8D87aVUTQ?t=2011 (I also recommend watching to full video presentation for even more detail.)

I’ve embedded the audio for the Ham Radio Workbench podcast below, but you can also find it along with show notes on the Ham Radio Workbench website.

Ham Radio Workbench is one of my favorite podcasts; if you like exploring a wide variety of technical topics, I highly recommend checking it out. It’s available on all podcasting platforms.

In search of benchmark signals: The International Beacon Project

by 13dka

If you – like yours truly – like to tinker with antennas and radios to get the most out of them, you likely have your own set of reference stations. If this is a new concept for you – reference stations are whatever stations you deem apt to check propagation, the general function of your radio, when trying to improve reception or comparing radios… They are ideally always on when you need them and come in various strengths and distances on several bands from all over the world. Traditional sources for that are of course time signals and VOLMET stations on HF, even though the latter are giving you only two 5-minute slots per hour for testing reception from a specific region and the former have their own specialities here in Europe:

A typical scene on 10 MHz, captured at home 30 minutes after the full hour: BPM voice ID from China mixed with something else, then Italcable Italy kicks in on top of some faint murmur possibly from Ft. Collins, in winter some South American time stations may stack up on that together with splatter from RWM 4 kHz lower…

A reliable source of grassroots weak signals is particularly desirable for me because I enjoy proving and comparing the practical performance of radios at “the dike”, a QRM-free place on the German North Sea coast. In the absence of manmade noise and the presence of an ocean adding 10dB of antenna gain, finding benchmark stations with “grassroots” signal levels turned out to be a different challenge than it used to be: With somewhat sizeable antennas the stations tend to be (too) loud there, even with the baseline ionospheric conditions under a spotless sun in its activity minimum. In short, my old benchmark stations didn’t work so well anymore and I had to find something new. Continue reading →

This is wonderful, Jeremy. There’s simply nothing like our boat anchors and vintage radios that continue to work perfectly and pump out amazing, warm audio. There was no such thing as “planned obsolescence” back then! Our radios like the HQ100AC will long outlast us!

Thanks again, Jeremy! I hope your HQ100AC enjoys a even more time on the air and keeps you warm this winter.
