Richard’s initial impressions of the Sony XDR-S41D FM/DAB receiver

Many thanks to SWLing Post contributor, Richard Langley, who recently attended a conference in Paris and picked up a Sony XDR-S41D. Richard writes:

The workshop closed around noon on Friday so I spent part of the afternoon walking around the nearby Darty consumer electronics and appliance store.

I wanted to buy a DAB/DAB+ portable receiver just to see what Europe was doing with digital radio. I bought a recently introduced Sony XDR-S41D DAB/DAB+/FM(with RDS) receiver for 79€ (about 11€ off list price).

I can use it in North America to listen to FM and take it with me when I visit Europe for DAB/DAB+ as well as FM.

It has reasonable sound from its 8-cm speaker and pretty good stereo sound on headphones. It has an automatic search mode on both DAB/DAB+ and FM and creates a list of available stations.

In my hotel room in the 13th arrondisement, I could receive 46 DAB+ stations. One of the stations is World Radio Paris (WRP) and they provide English language programming 24 hours per day from BBC World Service, Public Radio International, Radio France International, and Radio Canada International, among others as well as their own programming.

Another available station was Medi 1, which just dropped its shortwave transmissions. I recorded some of the WRP programming:

Audio Clip 1 (MP3)

Audio Clip 2 (MP3)

There is no line output from the receiver but I was able to use the earphone output and crank the volume to maximum to get an acceptable recording level without noticeable distortion.

Happy with my purchase and can’t wait to go back to Europe again, say to England, to try out DAB+ there.

I also spotted three receivers with SW capability on the shelves at the Darty store:

  • Panasonic RF-3500 for 45€
  • Brandt BR200D for 45€
  • Brandt BR120A for 15€

You don’t see SW receivers in North American consumer electronics stores anymore and I’ve not spotted any in airport duty free stores lately either.

I’ve been listening to the XDR-S41D at home and it sounds pretty good on FM, too, and does a good job of displaying the RDS information although a character or two is sometimes cut off the end of the data but that could be the fault of the station. Need to investigate that some more.

By the way, the radio doesn’t come with a case but I found (just before I was going to toss it) that it just fits in the magnetic-clasp case of one of those Air Canada amenities kits that they give you in business class (see photo below).

That’s the second Air Canada item I have recycled. They used to use full-ear headphones with disposable foam covers. They were a perfect fit for the deteriorating covers on my old Sony noise-cancelling headphones. I’ve since upgraded to Bose. 😉

Thank you for sharing your thoughts, Richard! The Sony XDR-S41D sounds like a keeper for sure and is certainly compact enough to easily accompany you on travels to Europe. I was not aware of World Radio Paris either–I see they’re available via TuneIn, so I’ll add them to my WiFi radio station favorites!

Fruit Cake Tin Radio

Many thanks to SWLing Post contributor, Ed Ganshirt, who writes:

I had an old car radio from the 1940’s I salvaged the parts from, and a rudimentary schematic to build by. I decided to re-assemble in the container I stowed away the parts in. Nothing special just another AM broadcast radio in an unusual cabinet (fruitcake tin.)

I love it, Ed! It’s like a broadcast band version of Rex’s Tuna Tin QRP radios!

It must have been a challenge to mount all of the components on that tin.  So how does she play?

Digitech AR-1780 on order!

This morning, I bit the bullet and ordered the recently introduced Digitech AR-1780.

I’ve had a massive amount of inquiries about this radio–mainly from readers in Australia and New Zealand–so I thought it would make sense to check it out and compare it to other portables.

This radio is only available from retailers in Australia (so far), so I placed the order with an Australia-based eBay retailer:

The price, with shipping, will equate to about $142 US.

The AR-1780 is being sent via the postal service so I don’t expect it to arrive for at least a couple of weeks. eBay estimates a delivery between August 17-28.

Stay tuned! Bookmark the tag Digitech AR-1780 to follow updates.

Escaping the noise while traveling

A Sony SW100, a PK Loop, and a pint of L’Écurieux brown ale. Lovely trio!

If you’re a regular Post reader, you’re probably aware that I enjoy a relatively RFI-free environment at my rural mountain home. RFI-free living is something of a luxury, even though our rural location also equates to appallingly slow Internet service.

But unfortunately, when I travel, I usually find that I’ve traded my RFI-free atmosphere for the chaos of noise-ridden bands. If you’ve ever stayed at a modern hotel and tried to tune to anything on mediumwave or shortwave, you’ll know just what I mean.

We’ve spent this summer, like last, near Québec City, Canada.  Near this fairly large city, I’ve been greeted by more than enough RFI to make up for the lack of RFI most of the year.

I attribute the atrocious RFI to the number of light dimmers the developers put in this condo complex and the proximity to a field of noisy electrical poles. Of course, all of the unregulated power supplies in the area don’t help, either. It’s a jungle of noise.

The PK Loop

Last year, I purchased a PK Loop portable HF loop antenna (about $150 on eBay)–specifically with hotels and this very condo in mind. I must say, it has been a welcome travel companion on this trip.

The Elecraft KX2 and PK Loop

While the PK Loop seems to pair well with my Sony SW100, I also love using it with my Elecraft KX2 for SWLing.

Sadly, the PK Loop doesn’t provide the noise mitigation of a large wideband mag loop antenna–like a Wellbrook or Pixel Loop–but it does lend itself to excellent portability and takes the edge off the noise.

While it’s easy to do my radio listening in the condo from a comfy chair, in reality, it limits what I can receive in a serious way. The 31 meter band, for example, is so heavily submerged in RFI that only the strongest stations can punch through (for example, Voice of Greece, Radio Romania International, WRMI, WBCQ, Radio Havana Cuba, China Radio International).

So, what can I do?

Hit the field, of course!

That’s right. Taking a page from the books of SWLing Post contributors London Shortwave and Clint Gouveia, I realize I can simply leave the RFI behind and seek a sound, radio quiet spot for SWLing/DXing!

My listening post last year–during the BBC Midwinter broadcast–in the parking lot of St-Anne-de-Beaupré basilica.

Over the past two months, I’ve taken time to escape the RFI and do a few live listening sessions and spectrum recordings in the field. I’ve always got my SDRplay RSP, Elecraft KX2, and Sony ICG-SW100 at the ready. In terms of wire antennas, I’ve deployed my NASA PA30 and even my QRP Trail-Friendly EFT, with good results.

Listening to the 2017 BBC Antarctic Midwinter Broadcast from the back of my vehicle in Saint-Anne-de-Beaupré, Québec, Canada.

I’ve also been experimenting with the homebrew Miniwhip antenna that SWLing Post contributor, Steve Yothment, provided earlier this year, based on the design used by the U Twente WebSDR. As Guy Atkins recently demonstrated, miniwhip designs do require some distance from sources of RFI, however.

The field is your friend…

Just a friendly reminder that if you live in an RFI-dense environment, you can certainly design a system to help mitigate RFI at home. After all, home is where you likely spend the bulk of your free time.

View of the Saint Lawrence River from my back-of-the-minivan listening post.

But, again, the easiest way to substantially increase your chances of snagging DX stations is to simply hit the field.

Join me in giving it a try. Find an RFI-free location with access to a couple of trees to hang a simple wire antenna–say, in a park, at the side of a rural road, on a friend’s farm…and if you find the listening good, make it your radio get-away. You’ll likely find that your portable shortwave radio can outperform your at-home tabletop receiver simply by removing yourself and your radio from the noisy environ of indoors.

When you first start doing radio in the field, it might feel a bit awkward–especially if you’re taking more than a portable shortwave along for the ride–but you’ll soon enjoy the fresh air ambiance and maybe even prefer it to indoors.  Even if you’re in a public setting where curious passers-by may want to know what you’re doing, as they undoubtedly will…When questions arise, take a (brief!) moment to educate your questioner(s) about the fascinating and nearly-forgotten world of shortwave radio––maybe you’ll inspire others to listen in, too.

And trust me: once you’ve been to the field a few times, you’ll start to look forward to playing radio in the great–and noise-free–outdoors!

Many thanks to SWLing Post contributor, Cap Tux, who writes:

The Zastone ZT-D9000 radio has actually been out for a while and is a Dual Band Mobile (Triband with option), nothing fancy there and bears a striking resemblance to the Icom IC-2820H (clone?). Options include GPS, Bluetooth, 220Mhz and LW (The latter is really weird!).

What caught my eye is the 2.3-30 MHz Shortwave coverage, a quick search on YouTube turns up a video showing Shortwave working!

Yes, probably as wide as a barn door with no filtering except the 12kHz default but an extremely useful feature if you did need a dual band mobile in your jeep/car.

Two other noteworthy features are a dedicated RX BNC antenna socket and a built in FM Transmitter so you can listen to it on the FM Radio in your car/jeep, very cool. A bit like a pimped IC-2820H. Also has all the bells and whistles a Dual Bander should have,

Very interesting, Cap! Thank you for sharing.  Honestly, I have a very difficult time keeping up with the radio equipment being produced and sold out of China.

And you’re right: what a surprise to find HF coverage on a dual-band mobile radio and especially longwave coverage! Like you, I wouldn’t anticipate stellar performance. The price is certainly “bargain basement” at $210 US shipped.

The Panasonic RF-088

Many thanks to SWLing Post contributor Jeff McMahon who writes:

“This vintage Panasonic RF-088 8-Channel Preset radio selling on eBay [see above] seems rather rare. In fact, I’ve never seen one.”

Click here to view on eBay.

I haven’t seen one either, Jeff. Appears to be pretty compact. At first, I was curious how an analog radio could have so many presets until I took a peek at the top of the radio.

Each preset is individually tuned. Hard to believe such a compact radio has a total of eight tuning mechanisms! Two presets are designated for FM, two for AM and four presets can be either. Pretty clever! Since it’s a Panasonic, I bet it’s a sensitive little portable.

At $59.80 US shipped, I’m sure someone will snag it.

With travels, solar eclipse events and family activities this week, I’ve had very little time to play radio.

Yesterday was a gorgeous day though, so I took the family to the Blue Ridge Parkway and (of course) packed a couple portable radios.

While we all enjoyed a picnic, I pulled out the AR-1780 with the intention of exploring its SSB performance and audio fidelity. I found an Islands On The Air (IOTA) activation with a decent pileup on 14,250 kHz.

I shot this short video with my smart phone:

Click here to view on YouTube.

Overall, I’m very pleased with the AR-1780 on SSB. The noise floor is pretty low, the filter selections are handy and the overall audio is comparable to slightly larger portable radios.

The dedicated fine tune control is quite handy, even though it’s oddly located on the right side of the radio (where one typically finds a volume control).

I’m putting together a short review of the AR-1780, but will need more air and comp time before I form any firm opinions.

For readers that have made it this far down the post, you might recognize a yet-to-be-released portable next to the AR-1780. Of course, I’m comparing it with the AR-1780 and its predecessor, but it’s not a production run unit (yet!), so I can’t comment on performance. Stay tuned, though, as I will be posting more in the coming days!

There’s a quick and dirty video review of the AR-1780 by Peter VK3YE, which highlights a few interesting quirks (if that’s the right word!) with this receiver. Some birdies, specs that don’t appear accurate, and a query over one of the bandwidth settings. Well worth a look!:

Thank you for sharing this video review, Robert!

Peter (VK3YE) has done an excellent job indeed summing up the AR-1780–his notes and comments mirror my own. I would have never caught that oddity with the 1.2 to 1 kHz bandwidth reversal.

I plan to post my full review in the coming weeks, but in the meantime release a few comparison videos. Click here to follow my AR-1780 posts.

Video: Daytime mediumwave shootout with the Tecsun S-8800

The Tecsun S-8800

About a week ago, I received a re-engineered version of the Tecsun S-8800 from Anna at the excellent online retailer, Anon-Co.

If you recall, I evaluated an early production unit of the S-8800 in February and while putting it through the paces, I discovered loud, warbling DSP birdies throughout the mediumwave and shortwave bands. Tecsun, to their credit, pulled the S-8800 from production to address the issue.

My schedule last week made it impossible to carve out the dedicated time I needed to begin an S-8800 evaluation.

Yesterday, however, I spent the afternoon with my family at Richland Balsam, the highest point on the Blue Ridge Parkway (6,000′ ASL) and a completely RFI-free zone. I brought the Tecsun S-8800 and a few other portables along for the ride–namely the Digitech AR-1780, the C.Crane CC Skywave and the Panasonic RF-2200.

I had just enough available space on my smart phone to record this one short video:

Click here to view on YouTube.

Let’s be clear: comparing any modern radio with the RF-2200 on mediumwave is hardly fair.

For one, the RF-2200 has been out of production for a few decades.

Secondly (what I never finished saying in the video is that) the RF-2200 has a large rotatable ferrite bar antenna that provides excellent gain. The RF-2200 simply wipes the floor with all of my modern portables as their ferrite bar antennas are a fraction of the size.

In other words, the RF-2200 was engineered to rule mediumwave like a boss.

On shortwave, the RF-2200 does a fine job, but isn’t nearly as accurate and stable as modern DSP receivers.

Spoiler alert

Still, as the video indicates, my final review of the Tecsun S-8800 will indicate that it is not a receiver for the serious Mediumwave DXer. It’s been my experience that few shortwave portables are excellent on both HF and MW.

At home, tuned to local station 880 AM.

Of course you can’t tell from the video, but the S-8800 actually sounds brilliant when tuned to a relatively strong/local AM station, but either a lack of sensitivity or internal noise makes MW DXing a challenge.

I spent the better part of two hours yesterday evaluating its daytime MW performance–the video is pretty indicative of my findings. The S-8800 struggles with weak stations, but does a fine job with strong ones. It’s overall audio fidelity almost matches that of the RF-2200 when tuned to a strong broadcast. I’ve yet to test evening MW

The S-8800 still has some birdies on MW, but they’re not the loud warbling kind found on the previous model. Tecsun did properly address this, though in full disclosure, I haven’t fully explored the shortwave bands yet.

Shortwave?

I suspect the S-8800’s performance on shortwave will be much better than mediumwave because the previous S-8800 showed excellent results. As long as sensitivity wasn’t harmed while addressing the DSP birdies, I expect it’ll give the PL-880, PL-680 and Sony ICF-SW7600GR a run for their money.

Still…the lesson learned yesterday?

The Panasonic RF-2200 is the indisputable champion of mediumwave!

A photo tour of the 2017 Shelby Hamfest

My Labor Day weekend was free of travel again this year, so I was able to make another pilgrimage to the Shelby (North Carolina) hamfest with my good buddy, Vlado (N3CZ).

The Shelby Hamfest–referred to, locally, as “The Grand-Daddy of them All”–has long been regarded as one of the largest hamfests in the southeast US. This is the third year I’ve made a concerted effort to publish a photo tour of the event.

I sold both my Hammarlund SP-600 and Hallicrafters SX-99.

Like last year, we set up a table in the flea market to sell a few items along with other good friends from the NCDXCC. In other words, once again, I was in selling mode, not buying mode, as I need to downsize some of my collection and use the money to offset costs of review radios, and some of the conferences I’m attending this year (including the Radio Preservation Task Force Meeting in Washington DC on behalf of our Shortwave Radio Audio Archive).

Overall turnout was a little less than last year, I believe. No doubt, this was due to the possibility of rain that never materialized. By lunch time the sun was out and the foot traffic increased.

A review of the Tecsun S-8800 shortwave/LW/AM-MW/FM portable receiver

$
0

Earlier this year, Tecsun released its long-awaited newest large portable: the Tecsun S-8800 portable shortwave/LW/AM-MW/FM receiver.

Though I fully intended to buy a Tecsun S-8800 for review, our friendly Hong Kong-based Tecsun retailer, Anon-Co, sent an S-8800 to me before I could. I’ve worked with Anna at Anon-Co for at least a decade and have purchased numerous radios for review, not to mention as gifts for family and friends.  When she insisted to send it as a gift, I decided I would (gratefully) accept the unit.

I received the S-8800 on February 1 and promptly posted unboxing photos here on the SWLing Post.

My new Tecsun S-8800 had a serious problem, though––one that two early S-8800e adopters noticed as well––internally generated noises, also known as birdies. And while most receivers will have a few minor birdies scattered across the bands, this S-8800 hosted a whole chorus of them, overwhelming the bands and making use of the radio difficult.  Read through this post thread for details.

I contacted Anna at Anon-Co and she immediately notified Tecsun; as a result, they halted distribution of the S-8800.

Tecsun took the S-8800 to their engineering team, and I’m happy to report they’ve now eliminated the horrible warbling DSP birdies of the initial unit I received.

On the S-8800s since released, while there are still a few minor birdies across the bands (more on that later), they’re merely what one might expect to find on any receiver. In short, the S-8800 now in production is a functional receiver, and a contender in its class.

I’ve had the S-8800 for a few weeks now and have had time to put it through its paces. What I present now is a review of the re-engineered Tecsun S-8800.

First impressions

Tecsun S-8800 Front Ang

In the spirit of full disclosure, I must note that I’m not as avid a user of large portables like the S-8800. Personally, my preference is for smaller, full-featured travel-friendly portables, or else larger tabletop models.  I travel often and like to pack lightly, so I rarely reach for anything bigger than my trusty Sony ICF-SW7600GR, or Tecsun PL-880, and more often than not, I grab the ultra-compact Sony ICF-SW100 or C. Crane CC Skywave.

But to say that I never reach for large portables would be inaccurate. In fact, I use a Grundig GS350DL daily; it’s my analog kitchen radio. I rarely move the tuning dial (a good thing, since it unfortunately drifts) because it’s locked onto my in-house SSTran AM transmitter on 1570 kHz.

What large format portables like the GS350DL and S-8800 can provide that a small portable cannot is broad, rich, room-filling audio. In my world, good audio is an important factor in overall signal intelligibility.

The S-8800 chassis resembles several other receivers: the Grundig GS350DL, S450DLX, and more recently, the Field BT, just to name a few.

The body is made of a hard plastic (not rubberized) and feels rugged enough. The knobs and buttons also feel tactile and of comparable quality to the previous similar models noted above.  With the rechargeable batteries inserted, it weighs about 3 pounds 4 ounces (1.5 KG).

The backlit display is large and viewable from almost any angle––even at a distance.

The main encoder (tuning knob) has appropriate amount of brake for most listeners. It wobbles very slightly, but functions amazingly well. I prefer it over its large portable predecessors, especially the 350GL. There is no soft mute while tuning, so band-scanning is a fluid, almost analog, process.

Both the “Band Select” and “AM BW” knobs have soft detents that mark steps in selection. In the field, I noticed that these can occasionally skip an increment when the detent only moves one position or the knob is turned very slowly. This doesn’t really affect functionality in any way, but I thought it worth noting nonetheless.

Like previous similar models, the S-8800 lacks a built-in keypad for direct frequency entry. That would be a major negative for a radio in this price class if the S-8800 didn’t come with one invaluable accessory:  an infrared remote control.

Infrared (IR) Remote Control

The Tecsun S-8800 ships with a IR remote control, and as far as I’m concerned, it’s great.

The remote feels durable, fits well in the hand, and the back has a place for it to balance on your index finger when holding…

But more importantly, the remote works quite well.  The controls are intuitive and the labeled buttons are quite easy to read. They’re also tactile and have a muted “click” response when pressed. Indeed, I wish my television’s remote was this well designed.

And the remote is quite useful, especially if you like listening from bed, from a porch, from the kitchen or dining room or den––or, in fact, from any space where you might wish to control the receiver at a distance. I believe its possible that every function of the S-8800 can be controlled with the remote––even the sleep timer!

Perhaps my dream remote for such a purpose would be backlit, but the S-8800’s remote is so simple to use, I’ve already nearly memorized where the buttons are located for nighttime use.

Operation Manual

The S-8800 ships with an informative operational manual, although this radio is intuitive enough that a seasoned radio listener will not need to reference it, save for advanced settings. Still, it’s written in clear language––with comparatively few English grammar errors––and the diagrams for both the radio and the remote are exceptional.

I referenced the manual several times to sort out ATS operation, saving/erasing memories, and to hunt down function shortcuts.

Features

The S-8800 is a feature-packed triple conversion receiver.  Here’s an abridged list of its features, focusing on those most radio enthusiasts seek:

  • Frequency coverage:
    • LW: 100 – 519 kHz (1 kHz & 9 kHz steps)

Wishlist? The S-8800 feature set is pretty comprehensive, but my dream large portable would also have synchronous detection and an RF gain control, though the latter is not common in the world of portable radios.  Fortunately, the S-8800 does have a local/DX gain toggle.

I’m sure some enthusiasts would also like to see Bluetooth connectivity as on the Eton Field BT, but I personally don’t miss it. I like to keep my HF portables free from anything that could potentially raise the noise floor.

With the exception of synchronous detection, the S-8800 has a solid, comprehensive tool set.

Performance

Over the past two weeks, I’ve had the S-8800 on the air almost every day. I’ve compared it with a number of receivers, but mainly its smaller sibling, the popular Tecsun PL-880. Below, I break down my notes by band.

FM

As is typical with my shortwave portable reviews, I spent less time evaluating FM performance on the S-8800.

With that said, I did compare the S-8800 with the PL-880, PL-680 and CountyComm GP5-SSB and a few other portables. The S-8800 found my benchmark weaker broadcasters with ease.

Here’s a short video demonstrating FM performance with a broadcaster over 100 miles distant:

AM/Medium Wave

I’ve had more inquiries about S-8800 mediumwave performance than I’ve had about any other radio I’ve recently reviewed. Why?  Well, for one thing, some radios in this particular portable format perform quite well on mediumwave––the C.Crane CCRadio-SW, for example, comes to mind.  Also, the S-8800’s large front-facing speaker lends itself to superb AM audio.

Unfortunately, mediumwave is not the Tecsun S-8800’s strong suit.

I did extensive testing, comparing it with much smaller portables: the Tecsun PL-880, the Sony ICF-SW7600GR, the Digitech AR-1780, the CC Skywave, and even a pre-production CC Skywave SSB. All of these portables had better sensitivity on mediumwave.

I posted the following representative video a couple weeks ago in a post:

To reiterate from my previous post, comparing any modern radio with the Panasonic RF-2200 on mediumwave is hardly fair.  For one, the RF-2200 has been out of production for a few decades.  For another, the RF-2200 has a large rotatable ferrite bar antenna that provides excellent gain. The RF-2200 simply wipes the floor with all of my modern portables, as their ferrite bar antennas are but a fraction of the size.

To my ear, the S-8800’s  mediumwave band seems noisier than its competitors. Perhaps this is why it struggles with marginally weak stations.

Here’s another comparison with the PL-880––this time at a totally different location:

Click here to view on YouTube.

With that said, when tuned to a local AM broadcaster, the S-8800 really shines. It produces rich audio which can be customized with bass/treble tone controls and by changing the AM filter width.

I also hooked up the S-8800 to my large horizontal loop antenna. This certainly did improve MW reception, but not as dramatically as I hoped.  Additionally, it seemed to be very sensitive to RFI in my shack even when hooked up to the external antenna.

If you took the S-8800 to the field, added a decent inductively-coupled magnetic loop antenna, no doubt it would improve mediumwave reception, but I still doubt it would come close to the RF-2200 in performance.  As long as I own the latter, I wouldn’t be motivated to do so.

Due to my schedule over the past few weeks, I’ve had precious little time to test the S-8800 on mediumwave at night, but some quick air checks proved performance was consistent with daytime testing.

I am pleased to report that no receiver overloading was observable during testing.

In short: if you’re only considering the S-8800 for mediumwave DXing, you should look elsewhere. I would suggest a dedicated AM broadcast receiver like the excellent CCradio 2E,  a vintage Panasonic RF-2200, or perhaps a used GE Superadio.

LW – Longwave

I’ve spent less time on longwave than I have on mediumwave and shortwave.

With that said, the S-8800 was able to receive our local airport beacons at night with relative ease. I was not able to catch any transatlantic longwave broadcasters, but that’s no surprise as it’s almost impossible on even my commercial-grade receivers during the summer months here in North America.

As I said regarding the mediumwave band, I suspect there are much better radios out there for the longwave enthusiast.

SW – Shortwave

At the end of the day, I believe the Tecsun S-8800 was designed with the shortwave and amateur HF radio enthusiast in mind.

The S-8800 has gapless HF coverage from 1,711 kHz to 29,999 kHz, can be used both in AM or Single Sideband (selectable LSB/USB), and has adjustable bandwidth filters tailored to AM broadcast and SSB/CW (ham radio/utility/pirate) reception. The filter widths are well-chosen for each mode: 6, 4, 3, and 2.3 kHz on AM; 4, 3, 2.3, 1.2, and 0.5 kHz on SSB.

It also has a dedicated fine-tuning control that adjusts steps based on the mode.

All of these are desired features for the HF radio enthusiast.

I’m happy to report that the S-8800 is a very capable shortwave receiver, perhaps even one of the best portables currently on the market.

In every comparison test I made on shortwave, the S-8800 outperformed each of its competitors.

Check out the videos below and judge for yourself:

I was pleasantly surprised by the audio in SSB mode and by how well the filters seem to work. Note in the video the warbling sound as I adjust the fine-tuning control on the S-8800.  But it’s actually only present as I adjust the fine-tuning control; I noticed no stability issue once on frequency.

External antenna

Since the S-8800 has a handy standard BNC connector and high impedance AM antenna socket on the back, I hooked it up to my large horizontal loop. In my testing, it handled that antenna’s gain very well and I was most impressed with the performance.

The front end seems to be robust, and selectivity––which is excellent––was not compromised by my antenna. I was able to pull apart two broadcasts with only 5 kHz of separation that were both quite strong. The S-8800 locked onto the stronger of the two stations with ease. When tuned to the weaker station, I used SSB reception on the upper sideband to ignore the noisier lower sideband which was buried in the adjacent signal. Once I zero-beated the signal, it sounded quite good.

Final thoughts about shortwave performance

Perhaps what the S-8800 has going for it on shortwave is a combination of very good sensitivity, excellent selectivity, and a feature all too often overlooked: good audio fidelity (via the internal two-watt speaker).

The AGC (auto gain control) is actually fairly stable on the HF bands (less so on mediumwave). Like the Tecsun PL-880, the AGC has a soft hiss response when the signal fades below the AGC threshold. While I’m not crazy about this, I must confess that it is pretty easy on the ears when fading is pervasive.

I did note one quirk that could annoy those wishing to copy narrow SSB or CW. If the filter bandwidth is set to .5 kHz and you’re listening to a marginal CW signal, the AGC sometimes mutes the receiver during CW dead space. It equates to very unstable audio with audio levels jumping around wildly. This happened more often when I was copying moderate to weak CW signals. I’ve even noticed it when listening to SSB ham radio conversations, but mostly in the narrow bandwidths. I usually keep the filter set to 2.3 kHz or higher and it hasn’t been a problem at these settings. It’s worth noting that I have observed the same AGC behavior in my PL-880 at times.

The S-8800 ships with two rechargeable lithium cells which provide hours of listening time from a full charge.

I never encountered overloading from local AM broadcasters on the shortwave bands, with the caveat that I never tested the S-8800 in an RF-rich urban market.

One thing I have noticed in general about the S-8800 is that it seems pretty sensitive to RFI indoors (electrical noise in the home, office, etc)––more so than my Sony ICF-SW7600GR, for example. If you live in a noisy environment and never plan to use an external antenna or take the radio outdoors, you might think twice about the S-8800.

Birdies

I’m pleased to report that Tecsun did properly address the “birdie” issue I mentioned at the beginning of this review. Still, like most receivers, the S-8800 does have some birdies across the bands. These birdies are well within the norm for such rigs:  a relatively stable heterodyne sound. I made a short video to illustrate what I mean when I talk about a birdie:

Click here to view on YouTube.

I spent one afternoon carefully mapping out all of the birdies I could find across the longwave, mediumwave and shortwave bands.

Here’s what I mapped:

As you can see, there are no birdies in the middle of sensitive areas like broadcast bands, amateur radio bands, etc. A good report, in my book.

Note that while tuning through the shortwave bands, I used 5 kHz steps. I suppose there’s a possibility I might have missed very weak birdies doing this, but any strong birdies would have been received and noted within the 5 kHz window. On LW and MW, I tuned in 1 kHz increments.

Summary

Every radio has its pros and cons, of course. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions. Following is the list I formed over the time I’ve been evaluating the Tecsun S-8800:

Pros:

  • Brilliant audio fidelity from built-in speaker
  • Dedicated AM bandwidth and fine tuning controls
  • Excellent, bespoke IR remote control
  • Capable SSB mode
  • Excellent shortwave sensitivity (see con: mediumwave)
  • Excellent shortwave selectivity
  • Excellent FM performance
  • Easy-to-read backlit LCD digital display
  • Remote control beautifully equipped for full radio functionality
  • Included 18650 rechargeable lithium batteries power radio for hours

Cons:

  • Lackluster mediumwave performance (see pro: shortwave)
  • No synchronous detector
  • No direct keypad entry (Pro: Remote control has excellent keypad entry)
  • Can’t charge and listen at the same time–not designed for AC operation
  • No backstand
  • Line-out audio level is a little high (hot)
  • When in narrowest SSB filters, AGC can’t reliably handle audio/signal changes
  • Slight “warbling” sound while using fine tune control in SSB mode
  • No RDS display on the FM band

Conclusion:

As I’ve already mentioned, if your primary use of the S-8800 is for mediumwave or longwave DXing, you should look elsewhere. While the S-8800 will serve you well with local AM stations, it will not dig signals out of the noise like other better-equipped AM receivers.  The GE Super Radio, Panasonic RF-2200, or CCRadio 2E are much better options.

But if you’re primarily a shortwave radio listener––? I think you’ll be pleased with the S-8800.

To my surprise, the S-8800 consistently out-performed my beloved Sony ICF-SW7600GR and my PL-880. I fully intend to compare it with other portables in the coming weeks and post the videos here on the SWLing Post. [I will update this review with any other findings.]

I did not mention this in previous posts, but the first S-8800 I received in January––the one with the birdie-chorus problem––also outperformed my other modern portables on shortwave. In part, I feared that when the Tecsun engineers addressed the birdie issue, it could have a negative impact on overall sensitivity. I’m happy to report that it did not.

What’s more, I realize that larger portables do have a place in my life.  You might have noted that I did all of my review testing and preparation outdoors, mostly in a nearby national park. I do this, in part, to insure I’m far away from any RFI, but also I simply love playing radio outdoors.

And the S-8800 was a pleasure to tune and use in the field. I really like the large encoder and find that the multi-function knobs, tone controls, volume, and other buttons are well-spaced–I believe I could operate most of this receiver’s functions with gloves on in the winter. And again, there’s that excellent remote control…

Is the S-8800 a good value? Let’s talk price

Only yesterday, Anon-Co announced the price of the Tecun S-8800: $268 US with free shipping to the US.

This review was in final draft form two days before I learned the price from Anon-Co. I had assumed the price would not be released for another week or two at least, thus I made a few predictive statements that I’ll now quote here:

I understand that the S-8800e is being sold in Europe for 339 Euro, roughly $400 USD, plus shipping. There is no way I’d pay that price; it’s simply too much.

If the price exceeds $300 US, I’d suggest careful consideration, as the S-8800 price would be venturing into the realm of used Sony and Panasonic benchmark portables.

But.  If this radio should be sold for less than $250, or even $200…?  Being primarily a shortwave radio listener, I would certainly buy this radio for that price.

In the end, the price is $18 higher than the $250 I mentioned in my review draft, but I assumed shipping would be tacked on to that price. So $268 ended up being pretty close to the mark.

So I believe the Tecsun S-8800 hovers at the top price threshold of what most radio enthusiasts would be willing to pay for a portable.  At $268, it’s over $100 more than the excellent PL-880 and only $20 less than the Tecsun S-2000. And for radio enthusiasts outside the US, it sounds like shipping will be added to the $268 price. I expect European consumers will pay a premium due to embedded (and required) sales tax and customs handling fees.

Click here to view at Anon-Co.

Nonetheless, I would still consider purchasing at the $268 US mark because of its shortwave performance, ability to connect external antennas, audio fidelity, and the included IR remote control.

I would like to see the price lower than $268. If the price were nearer the $200 mark, it would be a no-brainer––this radio would likely fly off the shelves, and I’d strongly suggest purchasing.

Perhaps, with time, the S-8800 price will decrease. In the meantime, if you have the budget, I believe the S-8800 would make for a nice field companion, pulling weak DX out of the noise with excellent audio fidelity to boot. It’s already been a great field companion for me…and, I’m sure, will accompany me into the field again.

The Eton Field BT

Many thanks to SWLing Post contributor, Chris Freitas, who notes that’s he’s published a favorable review of the Eton Field BT on his blog: Chris Freitas on Radio

The Field BT shares the same basic chassis as the Tecsun S-8800 (check out the review published yesterday) and several other receivers including the Grundig S350DLS450DLX, and the C.Crane CCRadio-SW.

Chris and I both agree that one benefit to this type of large portable is the excellent audio fidelity they can provide.

Read Chris’ full review here.

Not all large portables are created equally

The S350DL may look like a digital radio, but it’s actually analog inside and tuning is prone to drift.

Important clarification: The Field BT–just like the S-8800 and S450DLX–does not have the flaky analog tuning of the discontinued Grundig S350DL series.

Since I started publishing videos of the Tecsun S-8800 in action, I’ve received feedback indicating that many assume the S-8800 will drift off frequency like the 2008 era GS350DL.

It’s true that both radios share a common form factor, but that’s where the similarities end.

The S350DL is actually an analog single conversion receiver with a digital frequency display. The S350DL tuning knob has an inner ring for fine tuning and an outer ring for speedy tuning. The big disadvantage of the S350DL is that it drifts off frequency every time the wind blows. At least, that’s how it seems. It’s a little frustrating, and that’s why mine pretty much stays tuned to one station on my kitchen shelf. Even then, it manages to drift off frequency every few days.

The Eton Field BT, Eton Field, Grundig S450DLX, C. Crane CCRadio-SW and Tecsun S-8800, on the other hand, all have a pure digital tuning experience with no drift at all. Most of these are at least double conversion and the S-8800 is even triple conversion.

Chris, thanks again for sharing your review of the Field BT! It sounds like a major improvement over its predecessor, the S450DLX. I understand you’re also evaluating the excellent Grundig Traveller III–we look forward to that review when published!

Ed gives this Realistic DX-440 a bath!

Many thanks to SWLing Post contributor, Edward Ganshirt, who shares the following:
I found this critter [a Realistic DX-440–see photo above] at a flea market. At first I pondered as to when I had my last tetanus shot before handling it, then again it had something that I see rarely in these portable radios … a BFO..!

I always said that a shortwave radio without a BFO is like a Harley-Davidson with a top speed of 25 mph, so I bought it. On the way home I could smell a barnyard aroma. I ruled out chicken and hog but I think it could have been sheep or goat. So I decided to see how well it works. It took a little bumping around with loose connections to get it working. But first since it was going to be taken apart to service the case and knobs would get a nice hot bath in a sudsy ammonia citrus cleaner with a bristle brush. Also the PCB’s would get brushed down with a mixture of denatured alcohol and acetone.

Now for the hard part: finding the rickety connections. This turned out to be simple, just inspect each wire at attachment point. I found 3 broken wires that were re soldered. Now it is together I am looking for a 9 inch antenna. The one here is not original it extends 66 inches.

As to it’s performance, This Hogg can go up to 75mph now that I have the plug wires on. The user interface speaks to me as a lab instrument more than a daily listener which I think will become its role.


Absolutely amazing transformation, Ed!

I’m especially pleased to see you’ve given this level of TLC to a Realistic DX-440. I regret having ever sold mine as it accompanied me across the ocean when I studied in Grenoble, France, for a year just after high school.

The DX-440 and I did a lot of travel and a lot DXing together! I hope your DX-440 takes you across the globe, Ed!


DXing in a large suburban garden with the Eton Satellit & Bonito MegActive MA305 antenna

$
0

Hi there, the garden at my house is pretty small and as a consequence, I am very limited in terms of what antennas I can usefully employ. You can’t position anything further than about 10 metres from the brickwork and to compound this, we are surrounded on all sides by neighbours in close proximity. All very nice people, but all very noisy – electrically speaking lol. I simply can’t get far enough away from these sources of electrical noise to achieve excellent SNR.

The solution to my problem was ultimately a Wellbrook ALA1530 magnetic loop, but prior to that I used an end-fed random wire, the performance of which deteriorated as the months went by as the ubiquitous blanked of local QRM continued to increase. Eventually, I was forced outdoors, well away from my town – effectively catalysing my forays into the Oxfordshire countryside on DXpeditions. That first experience of listening to the radio on shortwave, in the absence of any QRM was enlightening to say the least and of course, subsequently, DXpeditions have become a mainstay of my listening activities. However, despite enjoying some great DX successes out in the woods, one has to be realistic about how often it’s possible to leave the house just to listen to the radio. This led me to the purchase of the Wellbrook ALA1530 magnetic loop. It proved to be a triumph of electrical noise mitigation and an absolute necessity in copying transatlantic medium wave signals in such a noisy and compact space. A total game-changer. The brilliant performance of the Wellbrook eventually led to me purchase a second, cheaper active antenna; the E-field Bonito Boni Whip and in turn, that purchase led me to the MegActive MA305, kindly supplied by Bonito themselves for objective testing.

Have DXing kit, will travel…everything you need in a small flight case…

You might remember my initial tests at home confirmed, as expected, that E-field antennas don’t work well in electrically noisy environments (except at LW frequencies in my experience) but outdoors, away from noise, they are superb. I have a number of reception videos on my YouTube channel – Oxford Shortwave Log which clearly demonstrate identical performance of the Bonito MegActive MA305 antenna and Wellbrook ALA1530 magnetic loop out in the woods. So, what if you’ve got a large garden in a suburban area that allows you to be just far enough from sources of electrical noise…how much of a difference does it make to the noise floor of your receiving equipment? Can E-field antennas such at the Bonito MegActive MA305 do the job? Furthermore, how well does a random wire work in a larger garden?

 My MegActive MA305 antenna system for mobile DXing…and another use for a washing line…

I was fortunate enough to know someone who owns a house with a large garden, quite close to my QTH (a 10 minute walk) and who was more than willing to let me set up my DXing equipment and sit around until the early hours of the morning, listening to and recording various signals on my Eton Satellit. In preparation, I set up the Bonito MegActive MA305 antenna and hung the radiating element on the washing line – sounds ridiculous but actually worked very well, placing it about 2.5 metres above the ground. I also set up a 40 metre longwire, which at its closest point, was still approximately 25 metres from the house, and 30 metres from the neighbours. This post will focus on the performance of the MA305; a subsequent post will detail the performance of the longwire.

The large garden I ‘borrowed’ for my DXing session with the Bonito MegActive MA305 antenna

Suffice to say, the MegActive MA305 performed admirably during my first listening session. In the middle of the afternoon I copied a very strong signal from The Voice of Korea around 15:44 hrs UTC on the 25 metre broadcast band, followed at 17:10 hrs UTC with a superb signal from The Voice of the Broad Masses 2, Eritrea, on the 40 metre ham band. Later on in the evening I copied Radio Mail with excellent modulation, CHU Canada with voice announcements (almost impossible at home), Myanmar Radio with an untypically strong signal and XEPPM Radio Educación from Mexico City with a signal I would normally expect on a DXpedition-proper with a large antenna.

My conclusions to this experiment are simply that E-field antennas can work in a suburban environment, if you are able to site them far enough away from adjacent sources of electrical noise. I don’t have empirical data on this, however, I can confirm that 10 metres proximity is too close at my QTH and 30 metres is sufficiently far away at this test location. One has to assume the houses nearby are similarly equipped to mine with electrical appliances that generate electrical noise. Thus, if you’re interested in a very well-priced, compact antenna and you live in an urban or suburban environment with access to a large garden/ outdoor space, an E-field Boni Whip or MegActive MA305 might well be suitable – and you’ll have a superb portable antenna for those listening sessions away from home!

Finally, I should mention the Eton Satellit. Much-maligned in certain quarters when it was first introduced into the market, it continues to demonstrate superb DXing credentials. I won’t forget some words of wisdom from a friend of mine and fellow DXer, with more than 3 decades of experience in listening to the bands on HF. He told me that Judging from his own experience with some of the original Grundig Satellit models of the 1980s and early 90s (namely the 400, 500 and 700) he was quite sure that the Eton Satellit is a considerably better DX performer than those vintage sets, that offered great sound for casual listening to international broadcasters, but didn’t perform too convincingly on weak DX signals. The Eton Satellit has been a revelation and I’m pleased to have played a small part in turning around the rather widely held view that it was less than worthy of the Satellit branding.

Fresh out of the box, the Eton Satellit has surpassed all my expectations…

Please find embedded reception videos below and text links to the Oxford Shortwave Log YouTube channel. My next post on this subject will cover the performance of a 40 metre longwire in this large garden environment. Thank you for reading/watching/listening and I wish you all great DX!

Many thanks to SWLing Post contributors Ed and Richard Langley for sharing information about the latest receiver from Gospell: the GR-227 digital radio car adaptor.

According to Radio World:

[…]The compact GR-227 can be added to car stereos, via a USB cable, in order to receive digital radio programs and corresponding data. Based on software-defined radio technology and using the xHE-AAC audio codec, the GR-227 is compatible with both modes of the Digital Radio Mondiale standard as well as the DAB/DAB+ digital radio standards.

According to Gospell, the GR-227 works with car stereos that are fitted with a USB port. Using the firm’s patent-pending technology, the adaptor behaves like a thumb drive when plugged into a USB port, making it compatible with most in-car receivers.

In addition, the GR-227 also features the Gospell Smart Tune App for Android. When partnered with an Android-powered car stereo, this lets users play back the broadcast audio program or benefit from data services.[…]

Read the full article at Radio World.

Richard comments:

“They call it an adaptor but perhaps it’s just an Android-controlled SDR receiver supplying audio output via a USB port, which could be connected to a computer or any other audio device with a USB audio input capability.”

I think he may be correct in that assumption because it may be the only way to get cross-manufacturer compatibility in a device like this.

The product information sheet noted that the receiver is supplied with a “triple band active antenna.” No doubt, the GR-227 will require adding a small external antenna to your car.

Still: an interesting product for sure! Perhaps the price point will be more reasonable that of previous DRM receivers? We’ll post updates from Gospell with the tag: GR-227

Irma-induced Radio Reviews

by Hans Johnson

The primary disaster we face here in Naples, Florida, is hurricanes.  Naples had been spared for over a decade until Irma.  So while I had prepared, I had not needed my supplies or equipment for quite some time.  This included the radios.

I went into Irma with two Freeplay solar and windup radios, a Unity and a Lifeline.  I got these radios probably over a decade ago.  As part of some work I was doing with VT Communications (now Babcock), I was involved with a radio project called Sudan Radio Service.

Both of these radios were being given to listeners as part of this project.  I wanted to have a better understanding of what they faced.  I had some conversations with Freeplay in London, explaining who I was and why I wanted these radios.  During a visit, I was able to purchase both sets with the proviso that I not sell them.

I checked them both out at that time with my focus being on shortwave as that is how Sudan Radio Service was then transmitted.  They were ok at picking out the strongest stations but that’s about it.  I never really needed or wanted to use the radios day to day.  And then Irma struck.

We left Naples on Saturday when we received a mandatory evacuation notice.  The storm struck on Sunday and we returned on Monday.

We were spared.  Many lost everything.  Some lost their lives.  We had a lot of trees down and some roof damage, but nothing substantial.  But we had no power.  Water had to be boiled.  Sewage was backing up in places because the lift stations had no power.  The stop lights were out (this was a real danger, many did not treat them as four-way stops and just blew through them.  But you never knew who it would be.)  A curfew was in place.  The cell phone system was in really bad shape.  I could not call or text my brother across town, let alone get access to the Internet via cell.

This link will give you an idea of what we came back to.  I am the guy sawing wood at 1:47.  (Lesson learned, have two chainsaws in case yours blows a gas line):

http://abc7ny.com/weather/watch-josh-einiger-reports-from-naples-florida/2391120/.

I had blown up some air mattresses before the storm so we slept on them on the screened porch.  I saw the Milky Way from Naples for the first time.

We wanted information and also a bit of entertainment.  Television was out of the question.  The HDTV stations are hard to receive with a great antenna and set in the best of times where we live.  So a battery-operated TV would have been a waste.  Radio was the only game in town, so it was time to put the emergency radios in service.

Sudanese Listeners Receive Unity Radios (Source: Lifeline Energy)

Both of these analogue dial sets cover AM, FM, and shortwave.  The Unity covers 3-22 MHz, the Lifeline just goes up to 18.  The former covers the old American AM band and the latter the new one.   The Unity uses a whip antenna and has a fine tuning knob.  The Lifeline has a bendable wire that fits into the carrying handle and came with an alligator clip and a length of wire.

Ideally, one would be listening a set that has been charged via the solar cell or listening with the set in the sun.  The last place I wanted to be was in or near the sun.  Trying to charge the set and then listen to it is difficult in practice.  It seems that the ratio was about one to one.  15 minutes in the sun would get you about 15 minutes of immediate listening.  It doesn’t seem that the batteries will hold a charge for long periods of time.  I could not charge them during the day and expect to turn them on the next morning, which was the peak time of day for radio to be transmitting local information.  The ratio for using the hand-crank was better, but I grew tired of cranking quite quickly.

I was interested in local stations, so shortwave was not a factor.  We only have a few local AM stations in Naples and I could not receive them (Irma knocked off or damaged a number of stations.)  I tried FM.  Even with the antennas retracted, both sets were overwhelmed by the local stations with certain stations bleeding through over much of the dial.  I could receive some strong, local stations.  With the outlet at Marco Island off and the other apparently on reduced power, receiving NPR was out of the question.

Given how many sources of information I was cut off from, my flow was greatly reduced.  My ignorance increased and learning vital information was hit or miss.  A neighbor told me about the boil order.  Passing on information was difficult.  When we got power I wanted to tell my brother, but the only way to inform him was to drive to his house.

One result was that I put these sets away and broke out my old Sony

ICF-7600GR and used it instead.  I guess I could have used it until I ran out of AA batteries.  I had plenty on hand and can easily afford them.  But that is hardly the case in Southern Sudan and many other places.

The Lifeline came with a few stickers on it that I could not read when I got the set.  Now that Goggle translate is so good I can read them.  They say in part:  “Everyone has the right to receive information,”  “Everyone one has the right to search for, receive, and deliver information.”

The real result of the test was a greater appreciation for how good I have it in many ways.  With regards to information, I have many sources and can readily receive it and pass it on.  It increased my respect for services like Sudan Radio Service and how important they are.  But most especially, I have a much greater admiration for listeners using these sets and what is surely their perseverance, patience, and determination to get information.


Many thanks for your field report of the Freeplay Lifeline and Unity, Hans!

I’m happy to hear you had no serious damage post-Irma. So many in the SWLing Post community have been affected by hurricanes this season.

I have never, personally, reviewed either of these Freeplay units–both are now discontinued and have been replaced with other models at Lifeline, I believe. As you state in your post, these radios are only available to humanitarian organizations. Through Ears To Our World, I have considered acquiring Lineline Energy (Freeplay) radios in the past. However, their radios tend to be rather large in size–we tend to go with smaller receivers that can easily fit in suitcases. In the past we’ve been very happy with the Grundig FR200 (Tecsun GR-88). 

The Lifeplayer MP3

Last year, we did purchase a Freeplay Lifeplayer to test. The hand crank charging mechanism is very robust, though quite noisy. The radio is digital, but performance is mediocre and tuning couldn’t be more cumbersome (5 kHz steps, no memories, only a couple of band steps.  Tuning to your favorite station could literally take a couple of minutes, depending on where it is on the band. When you turn off the radio (or it runs out of power) you’ll have to re-tune to the station again. That’s a lot of extra mechanical wear on the encoder. The real utility of the Lifeplayer is the built-in MP3 player and recorder–a brilliant tool for rural schools. Also, it’s robust and can take abuse from kids much better than other consumer radios.

Your main point, though, is spot-on: these radios serve their purpose, but we radio enthusiasts are incredibly fortunate to have much better grade equipment to take us through information backouts.

Thanks again for your review, Hans!
