I recently picked up a Sangean ATS-909X to use as a bedside radio.
This blog post inspired me to put together a video review of the ATS-909X as a bedside radio. The video review can be found on my youtube page [or via the embedded player below]:
Great video, Marty, and thanks for the thorough review!

In my role as director of our 501(c)(3) charity, ETOW, I’m always on the lookout for technologies that could improve the lives of those living at or below the poverty line in remote and sometimes politically-charged regions of the world that are usually off-grid. At ETOW, we prefer simple, rugged technologies that require no learning curve, that can be easily maintained, and that offer exceptional benefit to our users. Self-powered radios, of course, are ETOW’s mainstay, but we’ve also provided digital recording and playback devices, solar and hand-cranked power generation, and, of course, lighting.
When I first learned about the Waka Waka Power+, I had ETOW in mind. I reached out to Waka Waka and they sent a sample for me to evaluate.
The flip cover, which acts as a stand, offers detents which allow the user to angle the solar panel for optimum solar tracking.
The Waka Waka Power+ is a small, lightweight portable power supply built on a 2200 mAh LiPo battery pack. A built-in solar panel occupies one full side of the device, which charges the battery when placed in sunlight. On the other side of the device–behind a flip cover–is a large round power button and two protected Cree LED lights.
After charging my Tecsun PL-380, the Power+ still had about 50% of its battery available.
On top side of the Power+ is a row of four green LEDs that indicate the battery level.
The body seems to be made of a very durable plastic designed to operate in temperatures up to 80 °C (175 °F). It has a smooth surface and gasketed USB ports. The LEDs are protected behind clear lenses.
Let’s face it: operation of this flashlight is dead simple. No learning curve here, which suits ETOW’s use brilliantly. And brilliance, indeed, is what the device provides.
Press the large power button once to check the battery status; press twice, and the LED lamps are activated at their brightest setting–about 70 lumens, which lasts about 10 hours on full charge.
Each consecutive press decreases the LED brightness for a total of four brightness settings. The lowest LED setting (about 5 lumens) is perfect for reading, and should increase the light’s longevity to approximately 150 hours with a full charge.
Emergency? If you press and hold the power button for two seconds, the Power+ will flash “SOS” in Morse Code.
The Power+ also has a hole in the tilt base that allows you to perch it on top of pretty much any bottle and become a table lamp.
I used a bottle of single-malt, but any bottle will do!
You can also loop a string through the central hole and hang the Power+ from the ceiling–or the roof of your car or tent–for an overhead lamp. Fantastic design for useability!
The Power+ has two USB ports:
If you plug your Power+ into a typical smart phone charger or a USB port on your computer, it will charge the battery in about four hours.
If you’re on the go, or simply want to go green, you can charge the Waka Waka Power+ internal battery with the solar panel directly facing the sun. It takes about two days of sunny skies to fully charge the Power+. But you can use it even if not fully charged.
Most of the time I’ve used solar power to charge, I started with a battery at 50%–it took perhaps five to six hours of sunlight to bring the battery to full capacity.
The Waka Waka Power+ is the first solar-powered portable charging device that has actually impressed me. I’ve tested numerous flashlights and portable battery packs over the years; many have been effective as smart phone chargers, but were heavy or unstable (one, for example, literally melted down on my bed while charging–no kidding).
Clearly, I like the Waka Waka Power+. I’m especially impressed because this seems to be Waka Waka’s first product iteration. The Power+ is small, lightweight, tough (though not waterproof) and delivers what it promises.
Negatives? Well, the only one I can think of at this point is that it takes almost two days of sunlight (at least, where I live in North America) to fully charge the Power+ via the sun. It could take longer if you live in an area with less sunlight hours. To be honest, however, I’m still fairly impressed that a PV panel as small as the one on the Power+ charges this quickly.
I’ve charged my Moto X (2nd gen) smart phone several times during my travels; it even came to my rescue when I left my phone’s mobile charger at home and had nearly depleted my battery while using the phone’s GPS to find my way in unfamiliar territory.
I’ve also used the Power+ to charge my Tecsun PL-380, PL-310ET, and PL-880 shortwave radios. In each case, I effectively charged the radio’s battery from roughly 25% to 100%.
The Power+ easily fits in my Spec-Ops Brand Op-Order Pouch and even my Maxpedition EDC Pocket Organizer. It’s an ideal size to carry pretty much anywhere, and especially useful for one bag travel.
I also think the Waka Waka could be quite useful in some of the countries where ETOW works. They could have especial relevance in regions where mobile phone networks are in place–increasingly prevalent in rural Africa–but our ETOW partners (teachers and community supporters) have no means of powering the phones or else can’t afford to power them. I’ll certainly order a few and test them in the field.
The icing on the cake–? When you purchase a Power+, Waka Waka will donate a Power+ for humanitarian use (not yet to ETOW, but to other worthy organizations) through their network. It’s a “get one, give one” deal–and believe me, this helps out.
At $79 US, this is a bargain for a cool little charger/flashlight that actually delivers as advertised.
The Waka Waka Power+ can be purchased
SWLing Post reader, Bob C., recently shared his review of the C.Crane CC Skywave portable radio:
Well, I just received my new CC Skywave radio and it’s terrific! I own a lot of portable radios (including several Tecsun DSP sets), and the Skywave is a new favorite and will likely become my standard radio for travel.
Good fit and finish, great ergonomics, and easy to use. I was pleased to find that, despite what’s written in the ads and on the back of the radio, you can set the radio to receive FM down to 76 MHz by selecting the a 9 kHz MW spacing.
Great for international travel. The following is my brief review (by band):
Mediumwave
The Skywave is far better than any of the Tecsuns and is almost as good as the C Crane 2E (my best MW receiver). At my location (40 miles N of Chicago), the distant groundwave fringe includes WLW, WJR, and KTRS (St. Louis) – in descending order of reception potential. Most radios can get a whisper of WLW (though not discernible), while the other two are rare. The C Crane 2E gets WLW and WJR well enough that you can listen; KTRS is detectable. The Skywave gets WLW and WJR and you can tell that KTRS is there. That indicates that the Skywave is among the best. And there are no birdies nor whistles on the band. Nice.
FM
Just as sensitive and about 99% as selective as any of the Tecsun DSPs. The shorter antenna doesn’t seem to hamper reception at all. And, with no soft muting and a more logical tuning setup, it’s a pleasure to work with. Lastly, the stereo reception threshold on the C Crane DSP chip is significantly lower than that on any of the Tecsun rigs, so most signals decode stereo and simply sound better. Where I live, I have tons of signals that are 0.2 MHz apart (i.e. 101.9 Chicago, 102.1 Milwaukee, 102.3 Waukegan – and local) – the Skywave has no trouble separating these and providing a usable signal for all three.
Shortwave
Seems to do just fine. I have not had any overload issues with my unit and can pull in all as many SW signals and most of my other small portables. The lack of SSB is an inconvenience, I suppose, but I guess you can’t have it all!
NOAA/Weather radio
This band is great to have and is perfectly functional. I will say that this isn’t my most sensitive WB radio, but it’s not deaf by any definition. It’s just a little less sensitive to distant fringe WB stations than some of my other sets. But it does dependably pull in anything within 60 miles, so we’re only talking about ability to pull in distant fringe signals (which can be fun).
Air
I’ve played around with this a little and it definitely works better than expected. O’Hare tower is about 25 miles away and I get it clearly, along with aircraft that are (from what I can tell) basically anywhere within about 60 miles. The ability to scan is very helpful; however, catching a signal when someone is broadcasting is tricky. A little online research into local ATC frequencies goes a long way toward having fun on this band. The Skywave seems to work the Air Band better than the G6 and G3, my only other radios with this band.
So, overall, this radio has been a very pleasant surprise. No disappointments whatsoever. Kudos to C Crane Company for doing such a fine job with yet another radio.
Thanks so much for sharing your thoughts on the CC Skywave, Bob! Like you, I really love this little radio for travel and gave it a favorable review several months ago.
That’s an excellent tip about widening the FM frequency range down to 76 MHz by selecting 9 kHz steps on mediumwave. Brilliant!
Readers should be aware that some Skywave owners have noted a vulnerability to overloading and imaging in urban markets or where blowtorch stations are nearby. If your listening post fits this description, you may want to hold off until C.Crane has addressed the issue.
The CC Skywave can be purchased directly from C. Crane. It is also available at Universal Radio and Amazon.com.
SWLing Post contributor, Guy Atkins, writes:
My “bargain bin” $13.99 portable Basbon DSP receiver arrived yesterday from China while I was out of town. That was fortunate for the little radio, as my absence allowed it another day of life (in one piece) on planet earth.
The good: the radio’s case is surprisingly solid and of good quality. To hold the receiver you’d think you had a $50+ portable in your hands. The smallish and very basic LCD display (cleverly labeled “DISPLAY” for those who don’t catch on too quickly) looks crude however, and gives forewarning that crude performance awaits.
The so-so: strong, local FM signals sound intelligible but with lots of tinny audio and some distortion. Strong AM signals (which happen to be near or coincide with North America’s 10 KHz channel spacing) are adequate.
The bad & ugly: Once you get past the puzzling multiple button presses to get past the clock display into shortwave operation, the noises and hisses coming from the speaker will make you wish you’d left well enough alone! Strong SW signals audible on Kaito’s $17.99 low-end (and analog) WRX-911 are simply a noisy, tone-covered mess on the Basbon receiver.
I was curious if the digital hash and noise was the result of an unshielded DSP chip, so I opened up the receiver. These two pictures show both sides of the primitive PCB:
After removal of TEN (!) little silver screws holding the PCB board in place I could remove and flip it over. The square, multi-lead chip to the lower left of the LCD display is unmarked, and is presumably the DSP IC. I was contemplating making a small grounded metal shield to cover the chip, but as I moved the Basbon radio’s internals on my workbench the array of case buttons literally fell apart.
That’s the end of THAT idea! I have more interesting radio projects to spend my time on.
Thanks so much, Guy! While I’m a little sad the Basbon DSP radio performed so poorly, at $13 I suppose we can’t be terribly surprised. My Basbon DS-858 is yet to arrive–it took the seller 10 days to ship it and now it’s on the ePacket journey from China. Once received, my expectations will be adjusted accordingly.
In truth, like Guy, I often jump on radio deals like this in the off chance they may perform well for their price. Most of the time, though, I feel like I’m taking a bullet for SWLing Post readers–! (Ha ha!) Giving an honest assessment of a poor radio keeps anyone else from wasting their money.
Many thanks, Guy, for digging into the Basbon and for sharing your review with us!
A few weeks ago, SWLing Post contributor, Ron, sent me an eBay listing for a radio with which I was not familiar: the Aiwa FR-C33.
Ron wrote:
“I know you are primarily HF but here is something rather special and unique and inexpensive:
Aiwa’s response to C-Quam in the late 90’s was “AM Wide.” Apparently all this meant was a somewhat wider Murita ceramic filter.
But…the bandwidth just matches the 10,200 cycle limit imposed on AM stations today…try a Sony SRF-42 or SRF-A1 C-Quam receiver at night on today’s band and note that they’re just too wide.
I have one of these and can tell you the build quality is great…it has a tone control and on Sony Walkman headphones stations like WSM are just flat-out unreal in sonic quality…the speaker isn’t bad, either.
A nice big ferrite bar makes it a bit of a DX machine, too.
FM is also very good; even the weather-band add-on works too.
Very much worth a go for your collection and enjoyment[.]”
I’ve been enjoying the FR-C33 for a few weeks now; Ron’s assessment is spot-on.
The FR-C33 produces clear audio via its internal speaker, but where it really shines is with a pair of good headphones plugged in. Though it has no “Mega Bass” feature like many radios of its era, the Aiwa produces great bass tones via a good set of “cans” (I’ve been using my Sennheiser HD 428s).
The FR-C33 has a very useful tone control with a smooth, wide spread between the full bass and treble settings.
All of the FR-C33’s controls are fluid and functional.
AM (mediumwave) reception is truly fantastic. I find that the analog tuning wheel is easy to use and there’s enough room for the needle to easily travel across the dial without skipping stations inadvertently (a problem I often find with smaller analog portables).
It really shines, however, when you can center on a local broadcaster with a quality AM signal. While the FR-C33W doesn’t receive C Quam stereo, of course, its wide AM filter offers up excellent fidelity.
FM reception is also sound. While I haven’t done a formal comparison on FM, it receives my benchmark FM stations with ease and produces great audio fidelity via headphones. Sensitivity-wise, it might lag slightly behind some of the better DSP-based radios out there, but for an inexpensive analog receiver, it must be at the lead of the pack.
Ron, I really appreciate the recommendation–thank you! The FR-C33 is a keeper for sure.
Though these don’t pop up regularily on eBay, you can search for an Aiwa FR-C33 by clicking this link.
In June, I made a small leap of faith and purchased a (dead) Sony ICF-SW100 from Universal Radio (see the listing on right).
You see, for many years, I’ve dreamed about owning this wee little receiver, now a classic among tiny radios, but used ones are typically too expensive for my modest budget.
This time, seeing the ad at Universal, I spoke with Universal Radio directly to obtain more details about their defunct unit; while they simply didn’t know what was wrong with the Sony, they were able to very accurately describe its cosmetic and functional condition…I took a deep breath, and decided to take a chance on it anyhow.
In full disclosure, I have a secret weapon in my camp: my talented friend, Vlado (N3CZ), who is not only the most adept electronics engineer/technician I’ve ever known, but one who truly welcomes a challenge. The thought had occurred to me as I admired the wounded Sony, Wonder if Vlad would like to take this on–?
The answer, of course, was Yes! So I dropped the DOA Sony off at Vlad’s home last week. He disassembled the radio, only to discover that my ICF-SW100 was a victim of the (dreaded) damaged ribbon cable.
These radios are indeed brilliant, incredible performers for their miniscule size. Yet the first generation of ICF-SW100 radios–those produced before the fall of 1997–have a design weakness: the ribbon cables which connect the upper and lower portions of the radio’s clamshell design eventually fail. Multiple openings and closings bend and cut the cables, rendering the otherwise remarkable little radio useless.
SWLing Post contributor, Dan Robinson, recently shared his knowledge about the ICF-SW100 series. Dan notes:
SW-100 Seekers Beware
As shortwave veterans know, the classic SONY miniportables — SW-1, SW-100(S) and SW-07, represented some amazing technological achievements. SONY managed to shrink some fantastic technology into these receivers, including (with the last two in the line) — SYNC capability. The SW-07, which was the last of these receivers, still brings some high prices on Ebay.
But if you are searching for the ICF-SW-100S there are some things to consider and beware of. As everyone knows, the SW-100 suffered from the well-known ribbon-cable failure problem. SONY addressed this problem in later serial numbers, and changed the design of the radio case.
Modified SW-100s have a notch where the top cover meets the base.
There are some dishonest sellers out there who are trying to pass off older version SW-100s as modified ones. Usually, the tip-off is that the photograph in the Ebay auction will be dark or out of focus, so it’s hard to tell if the radio is the modified version or not.
It has become quite rare to find an original SONY modification kit, which includes a new top cabinet of the SW-100. And some sellers are trying to get as much as $300 for these, though they rarely sell at this level.
ICF-SW100 modification kit found on eBay at time of posting.
It’s also becoming rare to see SW-100S radios new-in-box. I had two of these, sold one and kept the other.
If you’re after one of these marvel radios, do what everyone should do when considering items on Ebay — ask many questions about [the] cosmetic condition, accessories, serial numbers, etc.
Universal Radio, a trustworthy seller I know, had fully disclosed the model number and problems with this radio, so I knew exactly what I was buying. Dan has a very good point, though: unless you know the seller to be honest, do your research and ask questions!
Vlado discovers the faulty ribbon cable (click to enlarge)
Back to my ailing unit: Vlado delivered the news about the ribbon cable via text message, and though I was well aware that the chances were high that was the ribbon cable, I was a little bummed, to say the least, to get the formal diagnosis.
Why? As Dan mentions above, you’ll find that the SW-100S upgrade kit Sony produced in the 1990s is no longer available new; sellers typically list these kits at prices in excess of $300 US. Out of my budget.
But Vlado, ever the intrepid engineer, had no idea I would be disappointed with this news; he was just giving me this FYI via text. Indeed, he seemed entirely unfazed, as in, hey, no serious internal damage here…
Another hour passed. Then came another message from Vlad; this one simply said: “Call me.”
Oh no, I thought. But I called, and Vlado answered cheerfully, “Hello? Tom, is that you? Sorry, I can’t hear you very well because your SW100 is playing too loudly. Hang on–let me turn the volume down!”
Vlad installs the replacement ribbon cable (click to enlarge)
“What!?!” I responded, in utter disbelief.
Yes, he’d got it working! It seems that Vlad had unearthed an old DVD player in his garage that he’d kept merely for parts. He opened it up, identified a ribbon cable with the right pitch, then cut and folded the cable to fit into the SW100. Ingenious!
That’s Vlado for you!
And should I be interested in replacing this used cable with a new one–or in repairing other Sonys–Vlad directed me to eBay listings for new cables which only total about $20, shipped. Truthfully, I’m in no hurry, as this one is functioning perfectly and changing out the ribbon cable seems to have no effect on stored memories, etc. With a single affordable eBay purchase of multiple cable sets, it occurred to me that Vlad would have enough replacement cables to repair the SW100 many times over…
So I bought the cables. (This one for the narrow cable and this one for the wider one.)
Needless to say, I’m very pleased with my “new” (to me) SW100. It’s a little masterpiece of receiver engineering in such a tiny package. And since the ICF-SW100 is unquestionably the smallest portable I own–and is one of the few I own with a proper line-out jack–it may very well become my go-to radio for one bag travel.
It’s in the bag: listening to the ‘SW100 before I pack it for my next trip!
Stay tuned the review…
As I’ve said, Vlad is one of the most adept repair technicians I’ve ever known. At my prompting, he’s kindly agreed to let me promote his services here on the SWLing Post. Vlad acknowledges that he “likes a challenge,” adding that he enjoys nothing more than making repairs even when”parts are scarce” and radio”surgery” is required. Moreover, his bench fees will be quite reasonable, especially considering what you receive: new life for a failing radio. So, if you’ve got an ailing rig on your hands, and don’t mind waiting for Vlad to get to it, send it to his radio emergency room, where radios (like my Sony) have life breathed back into them once again.
Long live the Sony ICF-SW100! And long live Dr. Vlado, who makes this possible with his creative (and nearly miraculous) repairs.
To contact Vlad, simply contact me with a description of your radio and its problem and I’ll put you in touch with Vlado.
After publishing my initial review of the Sangean ATS-405 on July 25, I contacted Sangean and requested a sample radio for comparison purposes. Back story: there were some receiver performance issues that I suspected may have been tied to my particular ATS-405 unit. Sangean kindly dispatched another ATS-405 which I received last week. The following is an update to my initial ATS-405 review.
In truth, there were two main reasons I wanted another unit to compare to my initial review radio:
I noted in my initial review that the initial ATS-405 had an ever-present noise, a sort of low-volume static hiss. The noise floor, while not high, certainly seemed to be higher than other comparable shortwave portables, and was most noticeable when tuned to marginal/weak stations. I suspect many listeners may not notice it unless they compare it with other portables.
Fortunately, my new review unit’s noise floor seems to be slightly lower than that of my initial review unit. [Perhaps this unit’s board is better soldered–?] The noise is still there, but can be better mitigated by judiciously using narrow filters and the three-position audio tone control.
I suspect this is a noise somewhere in the audio amplification chain, because I find it less noticeable with headphones, and more pronounced via the ATS-405’s internal speaker.
In terms of sensitivity and selectivity on the shortwave bands, I believe my new unit is identical to that of the initial review unit. That is to say, the ATS-405 is not an especially sensitive shortwave receiver, but fairly average, and thus will fit the bill for most but not for the discriminating weak-signal hunter. Frankly, even my $46 Tecsun PL-310ET does a better job of pulling in weak stations.
I’ve tried tinkering with the AGC settings and soft mute–very cool features!–in an attempt to improve sensitivity, but alas, these only help the quality and stability of the received signal.
Immediately after opening the box of the new ATS-405 sample, I popped in a fresh set of AA batteries and tuned the Sangean to 1600 kHz AM. [If you read my initial review, I noted a strong DSP birdie on 1600 and (to a lesser degree) on 800 kHz].
At first listen, I was happy to note that the new unit lacks the wild DSP noise that overwhelmed my favorite local station on 1600 kHz.
As I listened more carefully, though, I did note a metronomic “chick” sound that was also present but partially buried in the noise on my initial ATS-405.
Below, I’ve embedded audio comparing the two receivers:
Initial review unit:
New review unit:
Listening to these samples, I realize I may have had the filter set to the middle position on the first sample and the wide setting on the second (hence, the brighter tone).
To further demonstrate the difference between the two, I made this short video; I start with my initial review unit, then switch to the new review unit provided by Sangean:
Note that this was recorded at least 100 feet from my house on the tailgate of my pickup truck. DSP birdies on 800 kHz sounded very much like the 1600 kHz sample, save the noise level on the latter is slightly lower and there are no broadcast stations in the background.
None of my other portables have digital noises or birdies on 800 and 1600 kHz.
So, the bad news: I do still hear a noticeable (and slightly annoying) internally-generated noise on the new review unit. The good news: it isn’t as objectionable as that on my initial review unit.
In short: I stand by my initial review of the Sangean ATS-405.
While the new ‘405 review sample seems to perform better than the initial ‘405 sample, I find the discrepancy somewhat marginal, especially since I spend the bulk of my time on the shortwave and mediumwave bands.
I’m not a fan of production runs where units vary so greatly from one to another, making accurate testing difficult. Therefore it’s quite possible you might receive a unit that performs better than those I tested…but unfortunately, the opposite is also true.
So, if you’re a Sangean fan, if you don’t mind the birdies on mediumwave, and if you mostly listen to strong shortwave stations, you may entertain purchasing an ATS-405. The keypad layout is almost identical to previous Sangean models.
To be clear, of course, this radio’s negatives above have been viewed under a microscope; the ATS-405 is not a “bad” receiver, it’s just not that exceptional. Other than the added mute/AGC/squelch features, when compared to its predecessors, it’s really not a better iteration.
In conclusion? For the $90 US price, I believe there are better receivers out there–such as the Tecsun PL-600 (which, as a bonus, has USB/LSB reception–and saves you $10, to boot).
