XHDATA D-808 and Digitech AR-1780: Comparing size and appearance

Digitech AR-1780 (left) and XHDATA D-808 (right)

Tuesday evening, I received my long-awaited XHDATA D-808 from AliExpress via the postal service. Yesterday morning, I unboxed it and started charging the included 18650 Li-Ion cell. I haven’t properly put it on the air yet but if you’re interested in some initial reports, check out these previous posts.

Dimensions

I was  curious if the Digitech D-808 was identical in size to the Digitech AR-1780–I could tell even from D-808’s initial information that these two radios share a common ancestry.

To my surprise, they are not identical in dimensions! With that said, the differences are very marginal.

The D-808 is 7 mm wider and 2 mm deeper than the AR-1780.

To confirm measurements, I checked out the manufacturer specifications of both radios.  Oddly, the specs also indicate that the AR-1780 should be 3 mm taller than the D-808 but I don’t detect this difference. I measure them to be equal in height.

The telescoping antennas are identical in height and number of segments.

Of course, as you can tell from the photos, the D-808 body is light grey in color while the AR-1780 is black.

Batteries

The Digitech AR-1780 uses four 1.5V AA cells while the XHDATA D-808 uses one less common 3.7V 18650 Li-Ion rechargeable cell (included).

External Power

The XHDATA D-808 (left) and Digitech AR-1780 (right).

The XHDATA D-808 has a standard 5V Micro USB port for internal changing. The AR-1780, on the other hand, uses a much less common 7V DC plug.

Right panels are identical.

Having a 5V micro USB port is a huge plus for the D-808, in my opinion! While travelling, I always have at least one micro USB charger.

Backlighting

The LCD display appears to be identical in size and display information, however the D-808 has blue backlighting while the AR-1780 has orange backlighting.

Other than variations in button shapes and color, the only difference between the two radios is the location of the power button.

As Guy Atkins mentioned in a previous post, the D-808 keypad buttons are almost flush with the radio body. The buttons on the AR-1780, on the other hand, are more prominent and tactile.

Accessories

The Digitech AR-1780 shipped with no accessories–the only two items in the box were the radio and the owner’s manual.

I was surprised when I opened the D-808 box to find a padded carry/travel bag, USB charging cable and even a compact external wire antenna.

Summary

There are actually few differences between the XHDATA D-808 and the Digitech AR-1780 in terms of physical appearance and function.

All in all, though, I prefer the D-808 package which ships with a carry bag, power cord and external wire antenna. In addition, the D-808 uses a standard and convenient Micro USB port for charging!

In terms of size/weight, the differences are negligible and wouldn’t sway my purchase decision.

Over the course of the next week, I hope to spend some time comparing their performance on the air. Though they appear to be from the same family, will one sibling outperform the other?  We shall see!

Jack reviews the Digitech AR-1780

Many thanks to SWLing Post contributor, Jack Kratoville, who shares the following guest post:


A review of the Digitech AR-1780

by Jack Kratoville

As a previous post noted, the quest for the perfect radio drives us far and wide; in this case, as far as Australia. Since it’s rare these days to be able to walk into brick and mortar to touch, play and even bring home a radio to test; I’m grateful for online communities like the SWLing Post to research new and existing product. The caveat being “another must-have for my collection.”

I truly thought I had found happiness with my traveling Grundig tandem of the G5 and G6 – that is until the DSP chip was introduced. For the past 2 years, I’ve been satisfied packing the CCrane Skywave, Tecsun PL-360 and one wild card for domestic travel. My bottom line is when I’m listening to a certain radio in a given location, did I ever regret not bringing something else? The Skywave has satisfied over 95% of the time.

When the AR1780 popped up on this site, something about it piqued my interest. I had heard the Digitech name and it was always associated with a less than favorable opinion. This radio, however, was drawing unexpected praise. It was the video reviews that put me over the top with rich audio coming through even cheap condenser mics. I called Jaycar and had one shipped. Now you can add me to the list of those who are quite pleased with this addition to my radio family.

I’ll start with the primary reason to consider this radio – the sound emanating from the on board speaker. The AR1780 sounds better or as good as any unit this size. And this isn’t just a benefit for FM listening, but for AM/SW/AIR as well. I’ve never seen such tonal balance across all bands.

If you’re looking for a smaller portable with above par performance and excellent audio, you can stop here and place your order. Otherwise, on to my observations:

FM

I enjoy FM DXing and the fidelity of this band. Even though I’ve become accustomed to the sound of the Skywave (it does mellow with age), the AR1780 blows me away. Crisp highs and lows with rich bass that highlights both music and vocals. There is no tonal adjustment on this radio and, frankly to my ears, it doesn’t need one.

Performance is on par with the Skywave and other DSP units. While the Skywave has slightly better selectivity, the 1780 pulls in a tad more signal with its longer whip. The RDS feature works great and is a plus when skips and trop bring in distant signals.

Mediumwave / AM

As sensitive as the Skywave and G5. I’ve gone up and down the dial and my unit doesn’t produce birdies or hets anywhere. Very happy about that. For local signals, once again the sound is wonderful with choices of wide bandwidth. And even with distant music stations, rare as they may be, the AR1780 produces more fidelity than noise. When Zoomer 740 comes in full strength, this radio sounds as good as it gets. Where the Skywave has a tonal advantage is when filtering is at its narrowest. I can still hear signals clearly, whereas the Digitech can get a bit muddy. Depends on signal.

I’ll mention here that the advantage of CCrane’s products is upgraded filtering. The AR1780 burps and clicks when you enter anything on the keypad – even from the Skywave’s keypad if the radios are close to each other! Otherwise, they are very similar in response to outside RF and other noise producing electronics.

Shortwave

I receive everything on this radio as I do on the Skywave & G5.

Where I find weakness with the AR1780 is the soft muting and the scan feature is far, far slower than the Skywave. I’ve scanned for signals on other radios and loaded the presets on the Digitech.

I haven’t found any birdies yet, but it will whistle while starting up on Radio Miami, then calm down completely once fully captured. But that’s only when 9395 is the start up frequency. If I switch to SW and it starts elsewhere and I hit the preset for 9395 – nothing! Strange, but an acceptable artifact. I have to admit, it sounds great listening to music on WRMI!

SSB

I don’t have the Skywave SSB, but the Digitech is slightly less sensitive than the G5. Not sure if it’s due to filtering, antenna length, the DSP chip or all of the above. It’s there, but sometimes not worth straining to listen to. I haven’t tried an external antenna as of yet. The G5 doesn’t feature the USB / LSB option, so the Digitech is easier to tune. Full disclosure, SSB was never a deal breaker for me and I’m satisfied with what I can hear.

AIR Band

A touch more sensitive than the Skywave here. As all my testing is done strictly from the whip – that might be the advantage.

General

I have to say the build of this radio is very impressive. Buttons are very firm and responsive. The tuning knob is superb. As the weakest physical part of the Skywave, the AR1780’s knob, and its fine tuning counterpart, are spot on perfect. Nothing sloppy here.

Battery consumption (4 AA) seems above average, although not super-impressive. It’s hard for me to analyze at the moment as I’ve been playing with this radio constantly. I probably take more notice when I’m replacing 4 instead of 2 and may eventually jump over to rechargeable AAs. Interestingly, I took the 4 batteries I had worn down just one notch in the AR1780 and stuck them in a Sangean PDR-18. The meter on the PDR-18 showed only one bar or less.

The Skywave gives you 10 pages of 10 memories, the AR1780 gives you 50 pages! Even without explanation in the manual, setting these up are very intuitive.

The dial provides plenty of information. Curiously, if tilted while off, there are indicators for Music, Voice, Snyc, DAB & WB. While none are employed by the AR1780, perhaps there’s something else in the works!

What I find annoying

The display defaults to the temperature or the alarm. If you use signal strength or time during operation, it defaults to temp when you turn it off. Both of my Tecsuns will let you set display for both radio on and off. It bugs me most because holding the radio always sends the thermometer up by 10-12 degrees!

It takes a good 3 seconds to power up or switch bands. I’ve heard of other radios having this trait, but this is my first experience. And this action does use a bit of power because switching bands, not the dial light, will show the first signs of battery wear. (Again, I’ve had no issues with severe battery draw and compare 4 alkaline usage with my G5.)

The Skywave has spoiled me with its super-fast scanning. The Digitech is similar to most Tecsuns. I’ve noticed them all skipping segments on the SW band.

I hear a difference between FM stereo and monaural from the onboard speaker. This is the result of a right or left channel only feed to the speaker when the radio is in stereo. The Grundig Mini 100 did this and without a mono setting, it drove me crazy. I like to see the stereo indicator, but it looks like the AR1780 needs to be set in Mono when listening to FM through the speaker.

There are a number of general traits that the AR1780 shares with the Skywave that I would have preferred to be more like the CC Pocket:

  • I prefer a lock switch over a long-press lock button.
  • When you switch to a different page on the Pocket, it only changes that band and stays on the current frequency. Both the Digitech and Skywave switch over all bands to that page number.
  • One last minor annoyance (getting very picky here), the dial light seems to flash when you turn the radio off. The Pocket doesn’t.

OK, the bad

As a portable / travel radio, I can’t image why there is no pouch!

Add $5 and provide something to protect this in the go bag. At least this problem can be remedied. A pouch from the Sangean ATS-606 fits perfectly.

But the biggest flaw I found (and this may answer the power consumption others have noted) is the light continues to function in the locked position! All buttons are disabled, but press anything and the light comes on. I can imagine packing this radio and as it gets pressed against something else, the light remains on until the batteries are drained. A major design error here.

Conclusion

I’m more than impressed and extremely happy I made this purchase. I have no doubt this radio will be a primary travel companion. Since I always take a few on the road, surprisingly this won’t displace the Skywave. (I really enjoy that radio), but rather the veteran Grundig G5. While still considered one of my favorites, the Digitech provides as much performance and a few more features in a smaller package.

If I were choosing between the Digitech AR1780 and the Skywave SSB – that would be a touch choice. As I mentioned before, SSB has never been a deal breaker during travel and I love the original Skywave as is. Portable means smaller and the Skywave is the perfect size. I use the weather band more than LW, but the fidelity on the AR1780 is absolutely superb.

And while I’ve read the Skywave SSB is going through initial run growing pains, CCrane has been stellar when it comes to customer service and final product. They’re radio geeks like us – Digitech is simply a badge on a product manufactured by another company. (Jaycar seems like decent people.) Bottom line – let’s see how the Digitech is holding up after 2-3 years of usage.

I treat my radios like babies, but I’ve seen most wear down with unresponsive buttons, scratchy volume or fading displays. In fact, the only two grizzled veterans still operating at 100% are my Grundig G6 and Tecsun PL-360. Even my 7600GR’s volume is failing.

Worth it so far? Absolutely – without a doubt. Any future quirks, discoveries and disappointments will be shared.


Jack, thank you for sharing this excellent review!

I couldn’t agree with you more–the AR-1780 must have the best on-board audio of any compact shortwave portable I’ve tested. As you state, what makes it stand out is the fact that audio is wonderfully balanced across the bands. And what better way to check mediumwave audio? Why Zoomer Radio (CFZM) of course! One of my favorite night time catches. 

Thanks for the note about switching FM to mono while listening via the built-in speaker. I don’t believe I had tried that yet.

And, like you, I find the active backlight during keylock such an odd behavior. I actually opened one of my travel bags during the holidays to find that the backlight was somehow fixed in the “on” position…with keylock engaged! I supposed the LED backlight has little effect on battery consumption because I imagine this the backlight was engaged for as much as three days, yet the battery still showed full bars. 

The AR-1780 is a quirky radio, but by golly it’s a good one and a great value! Thanks again for the excellent review, Jack.

Keith is impressed with the Digitech AR-1780

Many thanks to SWLing Post contributor, Keith Batari, who shares the following:

I have just got the AR1780 and comparing with others I’ve had especially the PL-660 and PL-880 beats them both. Firstly the SSB does have an annoying mute when running, but the sensitivity and sound quality is fantastic, and that goes for all bands.

The airband sensitivity is also impressive with excellent squelch. Long wave sensitivity is low[…]. Tuning is without the quirks of the PL-880 and great on general coverage bands.

Headphones sound great. I’ve opened mine and the build quality is good with band trimmers and transformers.

If anyone has acquired the circuit diagram could the post it on the Google site.

If you want a radio with a lot of bang for your bucks, then look no further.

Agreed, Keith! The AR-1780 is certainly a value performer. Click here to read our comprehensive review.

I should add that while LW performance is not stellar on the AR-1780, it should suffice for LW listening in Europe, for example. The C. Crane Skywave series does not include longwave, so if you’re looking for a compact travel portable with LW service, the AR-1780 is a better bet.

Dave’s Digitech AR-1780 notes

Many thanks to SWLing Post contributor, David Morton, who comments with assessment of the Digitech AR-1780:

I’ve been using [the Digitech AR-1780] in Australia (southern Tasmania) for about 5 weeks.  In the last 10 or so days, I’ve got a 26m long wire hanging fairly reliably on a N-S bearing.  My history is that I trained as a marine radio operator in the early 1980s, but worked in commercial IT; so no real radio theory and I only just started listening to SW again since being a volunteer in the South Pacific in the mid 1990s.

Now, to this radio.  I quite like it although it has quirks I wish it didn’t have.  In the 1990s, I used a Panasonic RF-B45 and it was rock solid until it died a few years ago.  Every now and then, I try to fix it, but no luck…

Reception here is quite limited and that’s how I discovered the first quirk:  when it scans at SW frequencies it skips. For example it seems to jump from about 9400kHz to 11000kHz.  I also have an old Jaycar AR1747 and it also skips when scanning.  They also skip from about 26100 and restart at 2300kHz.  Whether it’s a design feature, or a fault, I don’t know. Other than that, I think it’s a great radio so far.  The AR1780 lets you type in the frequencies it skips, it just won’t scan them.

Until I start to find some reliable interesting stations (I’ve picked up some Radio NZ Int and BBC World Service), I’m doing a fair bit of listening to WWVH in Hawaii.  Sure listening to the time isn’t as fun, but it serves a purpose when comparing radios side by side.  WWVH broadcasts on 2500, 5000, 10000, 15000, 20000 and 25000 kHZ I think.  I can usually get 15000 subject to propagation at any time.

Until I gave it away, I also had a Jaycar AR1733 and it also skipped; they all probably share a common chip and skip the same frequencies although I haven’t checked closely.  This radio looks identical to the Skywave many of you mention.  The old AR1747 also had a Crane equivalent, and this was helpful as Crane’s manual was much better!

On the first tests with my long wire antenna, the AR1733 had a fairly clear signal, beat the old AR1747 and the AR1780 was the best.  The AR1747 is hard on its D batteries, so may have been handicapped.  As it got dark, I found the signal didn’t change much on 15000 kHz with any radio, but only the AR1780 would find 5000 kHz while scanning (since it skips over 10000 kHZ).  The AR1747 does not have a keypad, so all tuning is by a dial or the scan function.

Oh yes, a hint I’ve learned for Golan.  I gained the habit of punching  then the desired frequency, then .  The precludes the need to type in leading zeroes and trailing zeros.  For example, I get WWVH by  5000 , while 15000 is  15000.  This may go all the way back to the RF-B45, so I’ve had time to acquaint myself.

Next is batteries, the AR1733/Skywave needs 2xAA batteries, the AR1780 takes 4xAA as did the RF-B45.  I haven’t yet run down any batteries in the AR1780 yet, but all my radios with 4 batteries have always worked better than those with only two.  So the extra size is worth it, and the AR-1780 is a fair bit smaller than the old RF-B45.  The AR1747 was an exception, it took 4xAA and 4xD and AA’s were almost a waste of time in it.  But hey, it’s a telephone book size radio with a big speaker; so I keep it plugged in as much as I can.

Anyway, it’s almost 4PM here, we’re on DST so it’s GMT+11 hours.  The bands start opening up soon so I want to get back to the radio.  I’ve still got a lot of work to find the who, what and where of SW broadcasters.  At least logging them is easy these days, when you tune into something, just point the mobile and it and make a movie!

Thanks for your feedback, David!  I also think the AR-1780 is a gem of a little radio.

The XHDATA D-808 shortwave portable: A variation of the Digitech AR-1780?

Many thanks to SWLing Post contributor, Ivan, who shares the following:

In December, sales of this radio will begin. The seller promises to put the price of 60 US dollars. Radio of a level not lower than Tecsun PL-660 for such a small price is great! There is a video review on YouTube. Unfortunately in Russian. There is no more information on this radio on the Internet. I myself found out by accident.

Click here to view on YouTube.

Thank you for the tip, Ivan! I’m guessing this is yet another portable based on the Silicon Labs SL4735.

The display looks like that of the Digitech AR-1780 and the keypad configuration is nearly identical–the only visible difference being the shape of the SSB button which is rectangular on the AR01780.

The Digitech AR-1780 keypad.

The XHDATA D-808 Keypad.

The power buttons are also in different locations.

AliExpress has the D-808 in their catalog, but the price is listed at $2,000 per unit (!!!) with no shipping to the US. Perhaps the pricing formula changes if you place an order within Russia?

UPDATE: Ivan adds, “I talked to the seller of Xhdata D-808 on Ali about the crazy price claimed now. The seller replied that the price will be quite different and much more humane than what is now.”

Again, thanks for the tip, Ivan!

Post readers: If you have the XHDATA D-808, I’d certainly welcome a review. Please feel free to contact me about submitting one.

Purchasing the Digitech AR-1780 directly from Jaycar

Last week, I posted a review of the Digitech AR-1780–a compact receiver that is only sold in Jaycar retail stores throughout Australia and New Zealand.

Since I live in the US, I purchased my AR-1780 via an Australian distributor on eBay.

Several SWLing Post readers discovered direct orders can be placed with Jaycar, thus taking advantage of Jaycar’s sales.

A couple weeks ago, Post reader, Paul, shared his correspondence with Jaycar where they implied an order could be placed via email directly with a Jaycar representative. I reached out to this representative for clarification because I felt uneasy about even suggesting that readers send credit card information over email. I asked if they had a secure order form. I never heard back from Jaycar and have been too busy to follow-up.

Turns out, SWLing Post contributor, Troy Riedel, just placed an order for the AR-1780 via Jaycar and shared the details–all it takes is a phone call. Troy writes:

I ordered the AR-1780 from Jaycar.

I contacted them through their web site, exchanged emails with a Customer Service Supervisor and she told me that they actually have a toll-free U.S. number that goes to their Australian call center (staffed during their business hours)! FYI, it’s:

1-800-784-0263

I got it for $134 AUD or $103.40 USD shipped!

Thanks for sharing, Troy! A great option for ordering Jaycar products in the US.

If any Post readers in Canada have also successfully placed an order through this toll free number, please comment!
