Results of the Shortwave Portable weak signal shoot-out

RadiosShootOut-SonyTecsunSangean

Thanks to all who participated in our shoot-out!  Last week, I posted three recordings of a weak shortwave broadcast in an attempt to evaluate which recording–thus which radio–our listeners prefer. The test was “blind” in that, though four radios were evaluated, only three recordings were posted, merely labeled, “Sample #1,” “Sample #2,” and “Sample #3,” respectively.

The radios tested were not just average radios. Rather, they represent the best of the truly portable radios currently on the market, namely: the Sangean ATS-909X, the Tecsun PL-880, the Tecsun-PL660 and the Sony ICF-SW7600GR.

Indeed, the most popular question I receive from SWLing Post readers is about two or more of these models, asking,”which is best?”

The samples

To refresh your memory, I’ve embedded the audio samples below–but if you haven’t yet, I would encourage you to read our previous post (and the great reader comments following!) before proceeding.

The recordings in our samples are of Radio Romania International on 11,975 kHz. Normally, the signal would have been stronger, but propagation was rough, and QSB (fading) was pronounced at times. Note that I recorded all of these samples with my Zoom H2N digital recorder via a line-in connection, using the radio’s headphone jack. Since not all of the radios have a line-out jack, I used the headphone jack each time and simply set the volume and line-in gain to the same level.

Sample 1:

Sample 2:

Sample 3:

And now, here is the sample I intentionally left out in my previous post…Sample #4. I didn’t include it in the evaluation because, frankly, it was such a weak performer compared with the other three; I knew it would take last place:

Sample 4:

With that in mind, we’ll start with the radio behind Sample 4:

Sangean-ATS-909X

Sangean ATS-909X ($200-250 US)


Many readers guessed rightly that the Sangean ATS-909X was the radio omitted. Evidently, it is known for its lack of sensitivity when only employing its telescoping whip antenna. You’ll notice that, most of the time, the RRI broadcast is lost in the static.

Frankly, I was somewhat surprised that the ATS-909X didn’t perform better. It has a loyal following amongst SWLing Post readers and has been a popular radio on the market for the past three years or so. While I’ve used the ATS-909X in the past, I have never owned one, and had never done a side-by-side comparison.

To perform this test, I borrowed the 909X from a friend who usually has it hooked up to an external antenna. In fact, this is when I learned that the 909X performs admirably when hooked up to an external antenna.

In my tests, however, I didn’t want to hook up external antennas.  I believe that for a radio to be evaluated as a portable, it must be judged on its ability to receive signals from its telescopic whip antenna as a base line.

But let’s move on to the radios you did hear in our weak signal evaluation…

Let’s take a look at the radio behind Sample #3, the radio our readers voted to take last place in terms of weak-signal listening:

Tecsun-PL-880

Tecsun PL-880: Sample 3 ($150-160 US)


With the exception of three votes (out of more than seventy), Sample #3–the Tecsun PL-880–was overwhelmingly voted worst in this weak-signal shoot-out.

The bulk of your criticisms focused on the fact that the PL-880 did not handle fading as well as the other radios. When the signal was at a peak, it sounded great, but in QSB troughs, the signal became unintelligible and you could hear DSP artifacts and distortion.

But is the PL-880 a “bad” radio? Absolutely not. Indeed, I gave it pretty high marks when I reviewed it last year. It’s just not the best choice for weak-signal listening–at least in its current firmware version.  Note to Tecsun:  I do believe it may be possible to tweak this portable’s AGC circuit so that it handles fading better…

But let’s move on to the other contestants. Here’s our second-place portable:

Tecsun-PL660

Tecsun PL-660: Sample 2 ($110-130 US)


During the first day of voting, the Tecsun PL-660 actually had a noticeable lead on the other radios. I’m not surprised. The sensitivity was better than the rest of the contestants, in my opinion. The received audio was clear and seemed to pop out of the static better than the others.

Overwhelmingly, those who didn’t vote the PL-660 as best, voted it as second. Their main criticism was that the PL-660’s AGC was a little too active and less stable than the radio which actually took first place.

And with no further ado, here’s our winner:

Son-ICF-SW7600GR

Sony ICF-SW7600GR: Sample 1 ($130-150 US)


Surprised?  I was!

After I evaluated the blind test myself, I was certain the PL-660 would be the winner with its stronger sensitivity. But the result–and reader comments–proved me wrong. More of you placed a value on the Sony’s rock-solid AGC circuit which handles the peaks and troughs of fading better than the other contenders.

Commenters noted that the Sony’s audio and stability lent itself to easier, less fatiguing, listening. Keep in mind, though, that many of these same commenters mentioned that the PL-660 (Sample #2) would be their preference for identifying a station in under weak signal conditions.

Now let’s look at the raw data, and then discuss what it all means.

The data

The Sony ICF-SW7600GR was voted:

  • first place 41 times,
  • second place 2o times, and
  • third place once

The Tecsun PL-660 was voted:

  • first place 23 times,
  • second place 33 times, and
  • third place twice

The Tecsun PL-880 was voted:

  • first place never,
  • second place three times, and
  • third place 53 times

I’ve attempted to place this data into a bar graph to make it a little easier to visualize: RadioShootOut-ResultsIf you noticed that these numbers don’t completely add up, it’s because responses were inconsistent.

Most survey participants listed their preferences in order (i.e., first, second, and third place). Some respondents only listed their favorite of the three, while others only listed the one they didn’t like. No one responded with a tie between the radios, all had an opinion.

Another way of reading the results

SWLing Post reader “Radio Flynn” helped me with some additional data interpretation this morning. He put together this analysis (download as a PDF), and commented:

“[A]lthough a majority of people choose sample #1, nearly everyone ranked either sample #1 or sample #2 as preferred, and the average ranks are very close, closer than the raw percentages would indicate. I have not done a statistical analysis so I don’t know if the difference in mean rank between #1 and #2 is significant (in other words, I don’t know if there is a significant preference for #1), but you can say that either sample 1 or sample 2 would be acceptable to almost everyone, and sample 3 clearly last choice.”

Radio Flynn also pointed out that next time I do this sort of test (and I will be doing another!) that I should keep votes consistent by asking everyone to rank their preference. Excellent suggestion; I’ll be sure to do so.

So the Sony ICF-SW7600GR is the best radio…right?

Not exactly.

Herein lies the difficulty of suggesting the “best” radio for any particular listener.

This test only evaluated weak signal sensitivity under rather rough conditions. The Sony was “the winner” in this respect.

SideBySide-FourRadiosBut this doesn’t tell the whole story.

I’ve had my Sony ‘7600GR longer than any of the other portables in this contest and it is invariably the radio I reach for when I want to make a field recording. I prefer the Sony because it has good sensitivity, a stable AGC, excellent single-sideband selectable sync detection and it can handle being connected to a long external antenna. Indeed, it was the Sony I packed when I spent the summer of 2012 in an off-grid cabin in the Canadian maritimes. In short: my Sony ICF-SW7600GR is my “old faithful.”

But frankly, when I travel, I reach for the PL-660 more often than not. Why?  Yes, the Sony has great receiver characteristics, but its ergonomics leave a lot to be desired. I use my Sony when I plan to key in a frequency and leave it there. The PL-660 is a joy to operate, has simple direct-frequency entry, an excellent auto-tune feature, not to mention, a stable sync detector.

If I want to identify a signal buried in the static, I reach for the PL-660.

If I want to do casual listening and am less concerned with DXing, I reach for the PL-880. It’s a solid radio and has a quality feel to it (running neck-and-neck with the ATS-909X in this respect). Of this bunch, it has by far, the best audio from its internal speaker. If I want armchair listening, I reach for the PL-880. It’s also an excellent SSB receiver–one of the best in this group–and offers more filter selections.

In summary, it’s not always easy to suggest which radio is best…I must ask in response, “Best for what?” The data from this test proves this, as our readers who ranked their favorites backed up their choices with consistent and valid comments.

What do you think?

Before long, I plan to pit these radios (and perhaps another?) against each other in terms of their synchronous detectors in another blind test.  It may take a while to work this up. Your enthusiastic responses, however, completely justify it.

Stay tuned!

Shortwave Listening (SWLing): How did you get your start?

Analog Radio DialI love hearing stories about how shortwave radio listeners and ham radio operators got interested in the hobby. I’ll tell you about my experience, but I would enjoy hearing yours either in the comments section or by sending me an email. In the coming months, I will select stories to feature on The SWLing Post––especially if you have photos!

As I started to write a little of my personal history in radio, I felt a sense of déjà vu. That’s because in May 2011, Monitoring Times Magazine asked if I would write a piece describing how I became an SWLer and ham radio operator; of course this made for a nice segue into how I started the charity, Ears To Our World. After a little digging, I have discovered the unedited piece and added/updated where necessary.

So here’s my story–(now please share yours)!

A Love of Listening: How I Relate to Radio

Growing up, listening…

I’ve never been a fan of television.  Ironic, considering that I grew up in the seventies and eighties when most kids were glued to the tube, addicted to Nickelodeon.  Perhaps one of the reasons why is that I find the visual often distracts from what I want to hear. Maybe it says something about my reluctance (or inability?) to multitask, but I’m much better at simply listening, rather than listening while also being asked to watch. I prefer to close my eyes, to just listen––and allow my mind to construct images from sound.

My father’s RCA 6K3 console radio.

When people ask how I became so interested in radio, the answer comes clear:  I just love to listen. My father still has, in his living room, the vintage RCA 6K3 wooden console radio which emitted, like an aging, crackly-voiced Siren with her own kind of coarse charm, the various scintillating sounds that first caught my ear and captured my young imagination.

One of my earliest memories is of my father, tuning in WWV in Fort Collins, Colorado, on the RCA to set his watch to the atomic pulse coming through the aether, a practice he followed each Sunday morning.  Sometimes he would allow me to tune around afterwards––on these occasions, I would catch broadcasts out of Europe, Australia, South America, as well as places I could not readily identify.

Not long after, my great aunt unearthed in her basement a classic Zenith Transoceanic, which she offered me; I took the dusty unit into my room and promptly set up a listening post. Little did I know at the time that I was joining a fraternity of radio listeners around the world who also logged and listened to stations, as I began to do, far into the night. I often fell fast asleep listening to my Zenith; no doubt, some of those mysterious DX stations I heard over shortwave and medium-wave infiltrated my dreams with languages and cultures altogether unlike my white-bread American one.

Then when I was in my teens––again, in an ironic twist––a TV repair man who came to work on my parents’ set mentioned that he was a ham, and I was suddenly introduced to the intriguing world of ham radio. Though it took several years before I pursued my ticket, as I was busy with school, music, and other typical teen pursuits, my interest in the medium deepened.

While doing my undergraduate degree, I spent a year living and studying in France. At the time, the world wide web was still in its infancy, and my portable shortwave radio, which had helped teach me French back home, now became my English-speaking companion, bringing news from home courtesy of Voice of America. Unlike satellite television, cable TV, or an internet connection, radio was also inexpensive, vital for a poor student like me struggling to pay my own way in Europe. Through just listening, a virtual sonic flight home was free and nearly instant, arriving at the speed of light.

After graduation, once more stateside, I encountered two hams who were to become lasting friends and elmers: Mike Hansgen (K8RAT) and Eric McFadden (WD8RIF). These two talented hams nourished my keen interest in the hobby, and in their company, I soon found myself in the field experiencing the scrappy fun of hands-on radio contests. I loved how my resourceful guides worked so many stations with the lowest-powered QRP equipment and only the simplest, cheapest wire antennas, and moreover, that they often derived their station power from the sun. I appreciated the remarkable skill with which they milked such modest equipment, initiating contacts all over the globe.  With their steady encouragement, I finally got my ticket.

I’ve been a ham since 1997. Radio, no doubt, has influenced my decisions to travel, to live and work abroad, to pursue a graduate degree in Social Anthropology at the London School of Economics.  Whatever I did, I did while listening to radio.  I even changed my call not long ago to reflect my passion as a shortwave radio listener; my new handle is K4SWL.

Recently I found myself charmed and inspired by a BBC audio piece on Gerry Wells, the British radio repairman who in his eighties continues to do what he has always done, and is still sought for his skill. The story’s subject is truly enjoyable, if a bit of an anachronism:  most remarkable is its relevance in the new millennium due to the simple fact that old mid-century (and earlier) radios continue to function today, and are still relied upon by listeners.  As I listened to this report, I couldn’t help but wonder, as I have so often before:  why does radio have such powerful nostalgic appeal? I reckon that, at least in part, it’s because radio has always been the voice of reassurance, of comfort, during darker times, reminding us that we are human, yet reminding us of our ability to survive. Radio is a friend––or, perhaps, a “great-uncle, in cords and a cardigan,” as Jeremy Paxman characterizes the BBC in his recent defense of this valuable institution in The Guardian––whose warm, familiar voice is there even when other media sources, or the internet, are down.

Shortwave, meanwhile, is much like the world’s pulse––we check in, we listen, and we confirm:  all’s well, we’re still okay.

Listening as mission

One could say that listening to radio has shaped my life. I suppose that’s why radio has recently become a mission for me. Today, I’m the founder and director of Ears To Our World (ETOW), a charitable organization with a simple objective: distributing self-powered world band radios and other appropriate technologies to schools and communities in the developing world, so that kids like I once was, not to mention those who teach them, can learn about their world, too, through the simple act of listening. I want others––children and young people, especially––who lack reliable access to information, to have the world of radio within their reach.

Specifically, Ears to Our World works in rural, impoverished, and sometimes war-torn or disaster-ravaged parts of the world, places that lack reliable access to electricity (let alone the internet) and where radio is often the only link to the world outside. The heart of our mission is to allow radio to be used as a tool for education, so we give radios to teachers, who, in turn, use the radios in the classroom and at home to provide real-life, up-to-date feedback about the world around them.

Through the encouragement of our good friends at Universal Radio and the extraordinary magnanimity of Eton corporation, who donate our wind-up world band radios, in our first two years and on a budget of less than $3500, ETOW managed to distribute radios to schools and communities in nine countries on three continents––in Africa, Eastern Europe, Central and South America, and the Caribbean––as well as to both Haiti and Chile, where the dissemination of information through radio was life-saving when earthquakes struck.

Post-earthquake, ETOW radios continue to be a vital link for those in need in Haiti. Here, Erlande, who suffered a stroke in her early 30s and can barely walk, listens to one of our self-powered Etón radios, given to her by the Haitian Health Foundation.

Post-earthquake, ETOW radios continue to be a vital link for those in need in Haiti. Here, Erlande, who suffered a stroke in her early 30s and can barely walk, listens to one of our self-powered Etón radios, given to her by ETOW through their partner, the Haitian Health Foundation.

We’ve done all this through partnerships––with other reputable established non-profit agencies like us––that already help struggling schools throughout the world, and who believe, as we do, in freedom of and access to information. Creating these partnerships is an important move: due to the very nature of the remote regions we serve, extending our assistance demands persistence, financial resources, and logistical support, times ten. And often a great deal of patience. Just shipping radios to other countries usually involves detailed arrangements with national and regional governmental authorities (for example, to waive duties or taxes); once the radios arrive, safely distributing them to these remote areas can also be very costly and complex. We listen attentively to our existing partner organizations, who have often laid the groundwork in these regions, and have established reliable connections with communities in them. Their need is for resources—like radios.

By listening closely to and working cooperatively with other established organizations, we find we’re able to distribute radios much more cost-effectively, too. In other words, we can operate on a shoestring budget so that donations to ETOW are used wisely and to their fullest extent. For example, because of our strong partnerships, money otherwise spent on travel can be put into shipping costs instead, thus getting more radios to more of the world with less donated funds.

So far, our scope has been limited only by our financial resources. Meanwhile, we are looking to place radios in other countries farther off the beaten path; Mongolia recently received our radios. Yet we’re not simply focusing on expansion:  ETOW is establishing strong, lasting bonds with our schools and teachers so as to better serve their needs long term. We endeavor to replace their equipment and batteries as needed. We would also like to develop on-air teacher training programs; a new partnership with Oklahoma State University seeks to develop and disseminate content on important subjects, among them literacy and health education, so there is new and valuable content to listen to.

MT readers [and especially SWLing Post readers] will have already guessed why we prefer radio to, say, computers, for information access. It is because much of the world does not have the communications infrastructure to support access to the world wide web and other dynamic media sources such as digital television, wireless networks or even electric power or phone. [Simply take a quick glance at the map above which shows the world adjusted for each country’s Internet population; notice how central Africa is all but missing?] Political instability, meanwhile, can undermine even the written word [for examples, check out our tag category: why shortwave radio?].

FR200Radio, however, is simplicity itself: all one needs is a modest yet capable receiver, and one has instant––speed of light––access to local and world media. So far, every teacher we’ve worked with already knows something about radio; indeed, many of them have an intricate knowledge of broadcast schedules. But in these places it can take up to an entire week’s wages to pay for a set of batteries. Thus ETOW’s wind-up radios become vital–we effectively eliminate this cost, giving them steady access to information.

And the reports we’re hearing from the field have been overwhelmingly encouraging: Teachers in rural Mongolia, Tanzania, and Kenya are able to teach current events. Visually impaired children in rural Belize can listen to the outside world and hear music and languages they’ve never heard. Children in Haiti and families in Chile learned where to go to get food and medical care and information about loved ones affected by the quakes.  A remote community in southern Sudan was able to listen to reports of their burgeoning country’s first democratic election. Being able to listen is making a difference.

Listening and learning work together

Radio captured my imagination as TV never could, it travelled with me and taught me early on that everyone has a story. Listening to radio taught me, too, that each voice is different in the consideration of what’s meaningful or newsworthy. I learned to understand––or at least appreciate––the diverse perspectives I heard in my vicarious radio journeys, and from these sprang my own opinions, hopes, beliefs. Radio became my teacher, one who gave me, in my formative years, a global perspective.

Just as radio taught me, and opened my young mind, I’m convinced that it can teach and open the minds of others. In some parts of our world, futures are still written on the airwaves.  But it’s never just a one-way street–willingness to listen to those with whom we work helps us better serve them, but also to make the leaps of mind required to cross cultures, to become aware of those outside our Western sphere, to understand and grow and learn, ourselves.

Listen and learn. That’s ETOW’s tag line, but to some young people––and to me––it still means the world.
