XHDATA D-808: Another User’s Review (and discount codes)

 

By Robert Gulley

I admit to being hesitant to review this radio when XHDATA contacted me, as our own armchair portable radio guru, Jock, had written an excellent review of the radio back in June of this year, and because the radio has been out for some time (6 or 7 years, I believe). After a time, I decided my take on the radio, like any other, would be just another facet in considering its place in the radio world at large, or possibly on your radio shelf, and hence this review.

Lightweight and a Sturdy Antenna

As Jock mentioned in relation to other lightweight DX machines, this radio is indeed light, yet sturdy, and very easily portable. Unlike many small radios, care has been taken to make the antenna solid and tall. This means it can pull in a lot of signals safely (unless, like me, you are comparing it side-by-side with three other radios and find yourself having antenna sword fights as you move radios around, but I digress. Fortunately, nothing bad happened to any of the radios!). When sitting on a table, the built-in stand is stable, and allows pressing buttons solidly with one hand – the radio does not slide around or threaten to be knocked over in the process. That might seem like a minor thing, but many stands are less than reliable in this regard.

Operating the Radio

While I would prefer a slightly larger offset to the buttons from the surface of the radio, this did not cause much of an issue whether hand-held or on its stand. There were a few times when I thought I had pressed a button sufficiently but no response, but a second, harder press worked, so I just needed to take that into account when tuning in frequencies using the keypad, or when changing modes, etc.

The radio has a number of functions, clearly labeled, including operations performed when the radio is off, labeled in orange. Other orange labels indicate secondary or sub functions when the radio is on, such as the “Meter” function which, when in SW mode, cycles through the shortwave bands.

A small but useful feature I really appreciate related to this is the meter identification displayed along with the frequency as you cycle through the shortwave bands. For some reason I have a hard time remembering which set of frequencies is represented by which SW meter band. Perhaps with this radio I can finally get them firmly entrenched into my old brain!

Fine Tune Dial

The Fine Tune dial works especially well with a broad range of adjustment depending on the mode.

Another operating feature that I found very useful is the Fine Tuning dial on the side of the radio. This works as one would expect in Shortwave and SSB mode, allowing for slight adjustments to bring in a voice or CW signal in the amateur bands, but also allows one to off-tune from the standard receive frequency when a signal is being interfered with or picking up static etc.

This is nothing particularly new, but what is impressive to me is that it works for MW signals as well. Being able to go from 700 kHz to 701 or 702 kHz, for example, sometimes allows for a more intelligible signal, particularly at night when there can be multiple stations coming in on the same frequency.

On more than one occasion this was useful, especially since this means one does not have to change the tuning rate to make an adjustment. Your main tuning stays at the 9 or 10k you have set, and when you move the main tuning dial, it jumps to the next proper frequency. In this example, 701kHz becomes 800kHz with the next turn of the main tuning dial or up arrow,

Listening

The audio is good for its size due to the large speaker, and the multitude of filter options in the radio for every mode (except FM) allow you to tailor the audio to what you prefer, or what will allow you to mostly, or totally, eliminate interference from strong nearby stations. For those who like to listen to amateur radio bands, the filter capability is even more useful, particularly since it goes down to 500 Hz, great for listening to Morse code!

The number of filters is amazing given the price point of this radio, and it begs the question, if XHDATA can do this, why can’t other companies do this too? This is a big selling point for the radio in my book.

As I mentioned earlier, I compared three other radios to the D-808, a Sony 7600GR, a Sangean 909X2, and a C.Crane Skywave. The results were both predictable and surprising. Predictable in that the Sangean with the larger speaker had better audio, the Sony with SSB sync that actually works (unlike many models that try and fail!) was a bit clearer most of the time on SSB, and the Skywave was weaker in strength due partly, at least, to the smaller antenna, and lesser audio due to the smaller speaker.

What was unpredictable was when the D-808 pulled in stations better than the Sangean or Sony – not often, but some times. Similarly, the D-808 would sometimes hear two MW broadcast stations when the other three would only hear one. All three were used at times with a Tecsun AM loop antenna to boost MW signals, as well as with their bare ferrite antennas. Most of the time the MW signals were pretty even, but sometimes the D-808 won out.

While I have yet to own the perfect radio, and I have owned a lot of radios, this radio does what it promises, and does it well. As I note below, there are pros and cons and quirks to every radio, and what may be a quirk or a con to me may not be to others.

 

PROs, CONs, and Quirks

PROs

  1. Excellent sensitivity on FM (good telescopic antenna) and AM (internal ferrite antenna excellent given the size of the radio)
  2. Includes the AIR band, SSB with USB and LSB, and LW
  3. 6 filters for SW, 7 for MW/LW, and 6 for Air (WOW!)
  4. Fine Tuning Dial works in all modes to help reception
  5. Tuning Dial can be adjusted for Fast or Slow tuning steps, and can be set to STOP to lock in a station so that if the dial is accidently nudged, the station will not get changed.
  6. Direct Keypad entry of frequencies
  7. Feature rich for an (almost) ultralight radio
  8. External antenna jack
  9. Long-lasting battery
  10. Reset Button to go back to square one if needed

CONs

  1. While I do not mind soft muting, this radio does make a “chuffing” sound in certain modes when tuning manually (but not when finding stations with ATS). That’s not a deal-breaker for me, but it will be to some, I know. This is likely due to the AGC “attacking” the audio as it returns from the soft muting.
  2. Minor Nit: While the battery life is good with the rechargeable battery included, I always prefer AA-sized batteries for their almost universal availability.
  3. Memory access is limited, not by the number of memories, but by an easy way to tune through them. Memory Pages should link seamlessly for scanning purposes, but this is not an uncommon CON with many other radios.

Quirks

  1. Setting the Sleep Timer to “On” actually turns it off. Really.
  2. Sometimes if the Clock adjustment is set to Auto, an FM radio station that broadcasts RDS time and date info might reset the time to something different, such as when hearing a station from a different time zone. I prefer to set the clock manually to my local time (or more likely, to UTC time) just to keep it consistent, and that option is available for this radio.
  3. I have noticed when another radio is near, when changing the frequency manually, in addition to the chuffing noise of the D-808, the other radio will make a popping sound with each change. This is not likely to be an issue in normal operation, but if comparing two radios, or listening to two different radios at the same time, you will likely hear it.
  4. The alarm time set shows on the main display when the radio is turned off, regardless of whether the alarm is set to go off or not. This was very confusing to me at first, as I expected the display to go off when the alarm was not set to go off.

Wrap-up

This is a neat little radio that, as they say, punches above its weight class. It can fit in a jacket pocket easily, it’s lightweight, it has features which not many other portables have, or have as fully, and the audio is quite good for its size.

This is indeed an armchair receiver, but with the addition of a MW loop antenna, or a longwire plugged in for shortwave/amateur or LW/MW bands, there are many more opportunities for bagging distant stations.

There are enough features to make it quite usable for travelling, but not so many bells and whistles that operation becomes cumbersome. And with keypad entry for when you want immediate gratification, there’s no long minutes or hours of tuning manually to get to the frequencies you want.

I believe the radio comes in at a good price point, ticks most boxes a user would want for a radio in this class, and has a track record of good reliability after a number of years on the market.

Checking out the XHDATA D-808

By Jock Elliott, KB2GOM

Size matters . . . especially when it comes to antennas. In general, the more aluminum or wire you can get up in the air (presuming, of course, that it is properly designed), the more signal you are going to pull in. A radio friend has a 560-foot loop erected on his property, and its performance is, well, impressive.

I’ve had my share of high-performance antennas over the years, and I enjoyed them.

Lately, however, I have yearned for simplicity. So when I encountered the phrase “Ultralight DXing” a couple of years ago, it had a kind of magic allure to it.

At first, I was intrigued: “What the heck is that?” I wondered. After poking around on the internet, I discovered that at the heart of ultralight DXing was the notion of having a whole lot of fun trying to hear distant radio stations (usually on the medium wave band) with tiny, shirt-pocket-sized radios.

Gary DeBock got the whole ultralight DXing thing rolling in 2007. He already had deep experience in DXing, having worked 144 countries as a ham radio operator with a 1-2 watt transmitter he had built. That was his apprenticeship in radio propagation. Then in 2007, he wondered if it would be possible, using his skill and knowledge of propagation, to hear Japanese and Korean broadcasters from his home in Washington State using – wait for it – a cheap pocket radio: a Sony Walkman SRS 59. At 1 am on an autumn night, he put propagation and operating skill to work and heard a couple of medium-wave stations from Japan and one from Korea.

In November 2007, he posted his results on the internet and got a lot pushback, the upshot of which was: “How could you possibly do this?

To which he replied (in essence), “Try it and see for yourself.

Some people did try for themselves, some with notable success. For example, one DXer from Canada logged 300 stations in 30 days. The idea caught fire, and ultralight DXing was born, concentrating on medium wave stations because there are lots of them to DX. (Ultralight DXers have their own forum, which can be found here: https://ultralightdx.groups.io/g/main )

In the intervening years, ultralight DXers have experimented with exotic antennas and achieved some astonishing results, but for me, the soul of ultralight DXing is simplicity: a tiny radio, a pair of headphones, and a comfortable place to sit.

In 2021, DeBock published an “Ultralight Radio Shootout,” and when I encountered it online, I saved it (I’m a bit of a pack rat with interesting files). Earlier this year, I was rummaging through my computer when I rediscovered the Shootout and found that DeBock thought very highly of the XHDATA D-808.

Now, here’s the weird part: strictly speaking, the XHDATA D-808 is not an ultralight radio. A radio must be no bigger than 20 cubic inches to be considered an “official” ultralight radio. The D-808 is actually around 27 cubic inches.

Curious, I contacted the XHDATA folks, asking if they would like to send me one for review, which they did, without charge.

The D-808 measures just under 6 inches wide, 3.5 inches high, and 1.25 inches deep and weighs about a half a pound. It receives:  FM: 87.5 – 108 (64-108) MHz, LW: 150 – 450 kHz, MW: 522 – 1620 kHz (9k Step) 520 – 1710 kHz (10k step), SW: 1711 – 29999 kHz (including single sideband), and AIR: 118 – 137 MHz. It is powered by an 18650 battery that can be recharged by a USB cable.

Others have written extensively about the D-808, but my overall verdict is that it is indeed, a neat little radio for listening in general. Because it has a larger internal ferrite rod “loopstick” antenna, it can do a better job of pulling in faint medium wave stations than some of the “official” ultralights with smaller internal antennas. In addition, the D-808 has a longer telescoping antenna that makes it easier to hear faint shortwave stations.

On the face of the D-808 are 24 buttons that control various functions, and they pretty much “work as advertised.” There is, however, one small issue that some users may find confusing. Just below the orange power button is a circular button marked SSB. Push it, and it engages single-sideband mode and can be used on medium wave as well as shortwave signals. Below that button, in tiny orange letters is an indication: USB/LSB. It refers to the INFO button below, NOT to the SSB button above. If you press the SSB button, hoping to switch between upper sideband and lower sideband, it will not work, and you will think the radio is broken (I spent several minutes searching the manual, trying find out what was wrong). When SSB is engaged, press the button marked INFO between to switch between sidebands, got it?

Playing around with the D-808 on a rainy Saturday morning, I found that it is a “hot” receiver – for its size – on medium wave, shortwave, and FM. Using the UP and DOWN buttons to search for stations, and I found that it would, indeed, find interesting stuff to hear that I could not hear so readily on “official” ultralight radios with smaller antennas. It’s a small, fun radio that virtually begs me to find a comfy chair, clap on the headphones, and tune around to see what’s out there.

Having said that, if this were a trip to Santa’s lap, there are a couple of things I would change about the D-808. The first is the soft muting that occurs between tuning steps, which is accompanied by a mechanical “clunk, clunk, clunk” at each step in both the main and fine tuning knobs. It’s like driving down a highway with expansion cracks or tar strips every 20 feet . . . it’s annoying. My personal preference is for smooth, continuous tuning, and, even when a radio has jumps between tuning steps, it is possible to deliver a smooth, “clunkless” tuning experience such as in the CCrane EP-PRO or the Tecsun PL-880. You can, however, get around the clunking by directly entering the frequency you want using the keypad (be sure to press the FREQ button first) or by using the UP and DOWN seek buttons to search for stations . . . the radio simply quiets itself until it find the next signal. Second, while the D-808 seems to just sip power from the 18650 battery, I prefer portable radios that are powered by AA batteries, since they are so readily available in so many places. In the grand scheme of things, that is a relatively minor consideration.

Bottom line: the D-808 packs a whole lot of fun and pleasing performance into a package that can be slipped into a jacket pocket. Even more important, it delivers the simplicity of an ultralight: a radio I can grab, kick back in an easy chair, slide on the headphones, and tune around for a bit of radio fun, and I can heartily recommend it.

13dka Reviews: The new 2022 “Belka” (generation 3) general coverage receiver

The new 2022 “Belka” (generation 3) general coverage receiver

by 13dka

Since its introduction in 2019, the super-tiny Belka (back then called “Belka DSP”) shortwave receiver sure gained an enthusiastic followership among SWLs and hams. The main reason for this is certainly the way how the Belka is incredibly small yet playing in a different league than the various consumer grade, Chinese mass-production radios, particularly the DSP-based ultraportables: The Belka is an all-mode shortwave communications receiver with a completely different (direct conversion SDR) architecture, developed and produced by a radio enthusiast (Alex, EU1ME) in a small mom&pop shop in Belarus.

In case you’ve never heard about it amidst all the buzz about more popular brands, here’s the skinny:

The Belka offers true allmode (including NFM and CW) reception with a proper 400 Hz CW filter and individual settings for the low and high filter slopes for AM, FM and SSB. It has an AM sync detector and comes with a 0.5ppm TCXO-controlled local oscillator for absolutely spot-on, calibration-free frequency precision and stability, which makes SSB or ECSS reception of broadcast stations a pure joy. The second iteration “Belka DX” brought a slightly extended coverage down to 1.5 MHz and an I/Q output for panadapter display and/or processing via your favorite SDR software.

All Belkas are quiet and very sensitive radios with a surprisingly robust front end, the filters are better and its AGC works like you’d expect it from a communications receiver, without the artifacts and distortion the DSP radios are infamous for, and of course smooth, non-“muting” tuning in variable steps down to 10Hz.

The Belkas have no built-in speaker (available as option tho) but really excellent audio on headphones and external speakers and they actually give my Icom IC-705 a run for its money in terms of reception quality, and they do that for up to 24 hours on a single charge of the internal Li-Ion battery. This stunning feature set is crowned by the best performance on a telescopic whip antenna ever – the Belkas have a high-impedance (>10 kOhm) antenna input optimized for this whip and taking it on a walk is (really!) like having a big rig with a big antenna in tow…

Despite all this goodness setting the Belka(s) quite fundamentally apart from most (if not all) current and former, even much higher priced portables and simultaneously putting it solidly into pricey tabletop territory, it hasn’t put Tecsun et al out of business for a couple of reasons: One reason is that it can only be obtained from Alex in Belarus, which is now often assumed to be impossible (it isn’t, more on that later). Another reason is that it doesn’t try to compete with aforementioned multiband radios from China, so there is no FM broadcast band and – until now – no AM BC band, but most owners and potential buyers particularly in the US really wished it had at least the latter. Well, Alex obviously heard us! After the Belka DSP and the Belka DX, the new Belka is just called “Belka”, so in order to avoid any ambiguity I’m going to refer to this model as “Belka 2022”.

What’s new?

The most prominent addition to the Belka 2022 is the extended 0.1-31 MHz coverage, the previous version only started receiving at 1.5 MHz. With LW and MW included, its “pseudosynchronous” detector (as featured in venerable radios from Harris, Racal or Drake), the great filtering and the great frequency precision for hassle-free ECSS reception are promising that the “squirrel” is now an ultra-ultraportable companion for MW DXers as well.

Wlodek Shares an Air Raid-Prompted Radio Comparison

Many thanks to SWLing Post contributor and friend, Wlodek (US7IGN), who writes from Kiev:

Hello!

Because of another air raid alert, I can’t sleep and I decided to make a small comparison of the receivers of the 60s and the modern one.

Of course, you can not compare their size and weight, as well as some features.

This Chinese XHDATA D-808 was given to me by a friend for comparison. When he was just choosing a good receiver, I advised him to buy an old Sony 7600 series or Panasonic B65, for example. But he decided that modern technology is better at handling the task of receiving. But it turned out to be not so clear:

Radios:

73 de US7IGN!

Thank you for sharing this, Wlod. I wish the circumstances for the radio comparison were better–even though I know air raids have sadly become a fact of life for many in Ukraine, I can’t imagine sleeping through them. 

Your short comparison is interesting too. I consider the D-808 to be an excellent little DSP portable, but the audio simply can’t compare with your vintage radios. Indeed, the vintage receivers seem to handle the QRM a bit better than the D-808 as well.

Thank you for sharing this and wishing you the very best, OM.

Shortwave’s Giant: Carlos explores evangelical broadcasting to MENA

Many thanks to SWLing Post contributor and political cartoonist, Carlos Latuff, who shares the following guest post:


WINNING HEARTS, MINDS AND…SOULS!

Catechizing via shortwave.

by Carlos Latuff, special for The SWLing Post

During the Vietnam War (1955-1975), the expression “hearts and minds” became popular and referred to the US government’s strategy to gain allies among the South Vietnamese against the Vietcong guerrillas. Over the years this strategy has been used in different contexts. What I’m going to talk about in this short article is how the radio waves have served Christian evangelical churches, to win hearts and minds, specially in Africa and Middle East (MENA).

Different from what I did with the Ethiopian clandestine broadcasts, when I spent around 3 months monitoring, with evangelical radios it took only two days in January 2022; quite simple, since they’re stations with regular programming. Most of them have good signal reception, there’s no jamming from other countries and, despite transmitting in different languages, little translation was necessary since the content is always the same: religious preaching.

All listenings happened in Rio de Janeiro. The radio sets used in this monitoring were the XHDATA D-808 and an old analog radio Sanyo RP-8351, made in Brazil in the 70’s. A 7-meter long wire antenna was used in all listenings. Continue reading
