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!

SSB Reception Examples with the XHDATA D-808 Portable Receiver

5 Replies

In my earlier article on this receiver, I shared reception videos of three weak medium wave stations and a single shortwave outlet, all demonstrated in AM mode.

These two videos are of reception in SSB. The first example is true SSB reception–in lower side band on the 40m amateur band, while tuning a local on-the-air ham radio classifieds broadcast:

The next video demonstrates “ECSS” reception (tuning an AM mode signal in SSB). In this example I use a strong station so the audio quality and fine tuning accuracy of the XHDATA receiver can be clearly heard. Typically, ECSS is used by SWLs and DXers for AM mode stations that suffer from adjacent channel interference on one side or the other.

Short Videos: the XHDATA D-808 Portable SSB Receiver on MW and SW

29 Replies

I recently received a new XHDATA D-808 SSB portable receiver, after AliExpress had a $69 USD introductory sale. I’m intrigued by this new model, as it uses the SiLabs Si4735 DSP chip, the same “brains” that powers the Eton Satellit (and Executive version), and C. Crane Skywave SSB. I believe the same Si4735 is found in Tecsun’s PL-880 and the CountyComm GP-5/SSB. A key feature found in all of these radios is USB/LSB modes and 10-Hz tuning step in SSB.

It would be a mistake to assume that all portable DSP receivers with the same SiLabs chip will perform equally; quite the opposite! They all have reception differences that owners will notice. I certainly noticed differences in sensitivity, AGC action, audio quality, and (to some extent) variations in adjacent channel (splatter) rejection between receivers using the same bandwidth. I made these observations when I owned the PL-880 and GP-5/SSB radios. Differences in the circuitry surrounding the SiLabs chip, as well the sizes of MW ferrite loopstick antennas and SW/FM whip antennas contribute to each receiver’s personality.

Below are four videos showing the D-808’s reception of three weaker daytime medium wave stations from indoors at my suburban Seattle-Tacoma (WA) home, plus one video of a shortwave reception in the 41 meter band. The XHDATA D-808 is compared to C. Crane’s newest Skywave radio, the SSB model, and the Eton Executive Satellit. Although brief, these tests show how the new XHDATA portable is a welcome competitor to the field of modern, compact SSB-capable radios:

What about single sideband? These four videos show reception in AM mode only, but rest assured the D-808 is very capable on the SSB modes of LSB and USB! A separate fine tuning rotary wheel on the right side of the radio’s case offers adjustment in 10 Hertz increments. The effect feels very similar to tuning CountyComm’s GP-5/SSB “walkie-talkie” style receiver. The plus or minus (+/-) offset is displayed in multiples of 10 Hz steps as “-1”, “-2”, “-3”, and so on.

I hope to post some future videos showing SSB usage of the D-808.

Soft mute. The dreaded soft mute is present in AM and SSB mode to some degree, but I do not feel it is excessive. Like most radio hobbyists I’m not a fan of soft muting and prefer uninterrupted tuning with no sign of “chuffing” or lowering of noise or audio. The amount of soft mute on this radio seems the same as the Eton Executive Satellit in my opinion.

What else to like? My take–

Audio. I find the D-808’s audio quality to be slightly more mellow or warmer…I like that, especially on FM! Audio on the MW and SW bands still has a crispness that aids in DXing on those bands, however.

18650 Li-Ion battery. Not all may agree, but I like this style of battery. The D-808’s internal circuit shuts off when the battery is fully charged, or after 10 hours of charging. The radio comes with a 18650 battery and a USB cable; the owner supplies a common 5V USB charger.

RDS on FM. This is a feature lacking on the Skywave SSB, but it is present and performs as expected with the D-808. The XHDATA radio lacks the Skywave SSB’s NOAA weather presets, however.

AM filter bandwidths. Interestingly, this receiver supplies two additional narrow AM mode bandwidths lacking in the Executive Satellit: 1.8 kHz and 1.0 kHz. It’s good to have options, although such narrow filters in AM mode sound a little muffled (offset tuning helps). The Skywave SSB does offer 1.0 kHz in AM mode, but has a 2.0 bandwidth in place of 1.8 kHz.

Backlighting. If desired, the D-808’s easy-on-the-eyes white backlight for the display can remain illuminated continually. Bravo, XHDATA! Now, if we could persuade more manufacturers to add backlighting to the keys themselves (a la the Degen DE1103/Kaito KA1103/Eton E5), we’d have more choices use in low light conditions like camping or bedside use.

Handy size. Probably a third larger than the diminutive Skywave SSB, the D-808 is still a very handy size that will fit most coat pockets, and is a smaller receiver than the Eton Executive Satellit. As you can tell from my videos, reception doesn’t suffer due to the smaller size.

Design. OK, this one’s very personal! As a graphic designer I have a real soft spot for any receiver that looks as good as it sounds, no matter what the technology or vintage. The D-808’s look really appeals to me and adds to my enjoyment while operating it. There are no unnecessary protrusions, ridges, or visual do-dads on this XHDATA model. In fact, I seem some design clues from the stylish Tecsun PL-880 in the D-808. The radio also has a quality feel to the plastic case and buttons, giving it a more “upper class” impression during use.

Antenna jack. The D-808 has the standard 3.5mm antenna port on the left side of the receiver. This is an addition I appreciate, and wish that C. Crane had included one on their Skywave SSB model. I tried this external antenna jack with an amplified PK Loops’ shortwave antenna and the combination performs excellently.

Minor annoyances

So far, the list is short! As a sacrifice to style, the manufacturer has kept all front panel buttons almost flush with the case. The effect looks great, but they are almost too low and close to the front panel. Those with larger fingers may find operation awkward or frustrating. Also, entering a shortwave frequency with less than five digits (i.e., below 10,000 kHz) requires a trailing push of the Frequency (FREQ) button.

I encourage other new owners of XHDATA’s D-808 to leave their comments below. Where does this portable rate among other radios you may own?

Jack reviews the Digitech AR-1780

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.

Michael is favorably impressed with the C. Crane CC Skywave SSB

Hi Thomas,

I took the plunge and purchased the Skywave SSB. It was under the tree on Christmas morning.

It was with some trepidation that I unwrapped it and installed a pair of AA batteries. I had read all the reviews regarding whistles and whines and had decided to give it a go anyway, particularly with the knowledge of the manufacturer’s excellent reputation for product support.

I am pleased to report no whistles or whines so far!

This morning I was listening to the breakfast club net on 3973 kHz. Reception, with just the whip, was not quite as good as my Commradio CR1-a with the W6LVP loop, but still very readable, and good enough to put a smile on my face and remove any thoughts of returning the radio to the manufacturer.

Air band, Weather Channel, FM, AM all seem to work great. I bought the radio primarily to throw in the bag when travelling, and can’t wait for the next business trip! I will still take the PL-880, and do some comparisons.

If I could change anything on the Skywave SSB, It would be to soften up (or remove) the detent on the tuning knob.

Holy Grail definitely comes to mind !!

Excellent, Michael! It sounds like your Skywave SSB is one that received a proper calibration and quality control run! I think you’ll find it makes for a superb compact travel radio.

Thanks for sharing your review!

As a side note, my full (4,300 word–!) review of the Skywave SSB has been published in the January 2018 issue of The Spectrum Monitor magazine. You can purchase and download the issue for $3, or (better) purchase a one year subscription for only $24. As I’ve said before, TSM is one of the best values in our radio hobby!

Exotic shortwave DX copied in Rio Capim, Northern Brazil

6 Replies

The beautiful Capim River in a land of Jaguars, Tarantulas and occasionally, wonderful shortwave DX

Hi there, I returned from my third trip to the Rio Capim area of Pará, Northern Brazil about 5 weeks ago, having been out there for exactly a month. Now, whilst this was strictly a business trip I always make time to tune around the bands, mostly shortwave, in the hope of copying some interesting DX. My previous two trips were reasonably successful; however, I didn’t really hear anything new – just lots of Tropical Band – and tropical stations with much greater signal strength and clarity. Part of the problem is one of which most of us suffer from – the dreaded local QRM. Even in the depths of the rain forest noise is present from building electrical systems (particularly lighting) and other equipment. In my first attempt to escape the noise on this trip I ventured out of my accommodation building (basically a very large hut) to the wire fence that separates us and the larger fauna (although having said that, the monkeys and everything else that lives in the area appears to have no difficulty scaling a 6 foot fence – funny that! ). Anyway, ultimately, you’ve really got to want to hear something special quite badly to venture out. I suppose it could be the definition of hard-core DX! I tried this only once because as I was copying a very nice signal from Radio Guinea on 9650 kHz, I found myself about 2 feet from a Tarantula Hawk Wasp dispatching a very large spider (check out the very brief video on my YouTube channel). That was me done for alfresco DXing in the jungle.

Bonito’s USB-powered MegActive MA305 E-field antenna up a tree…performed superbly in Brazil

Fortunately, I was lent a 4-wheel drive truck for the duration of my visit and so I decided to find a quiet location to park up and listen to the radio – therefore only having to venture outside (at night) to place my antenna. One evening after dinner I got in the truck and drove around the site for a while until I found a location, effectively on the edge of the jungle that was mostly very quiet. Perfect…as long as I didn’t end up as something else’s dinner. I took the super-compact USB-powered Bonito MegActive MA305 antenna with me on this trip because I’d already tested it at home on DXpeditions and in Crete and thus I was confident as to how superbly well it would perform in a quiet location. To supplement my antenna choices, during the first weekend, I made the 90 km drive to the nearest town and bought, amongst other supplies, a 40 metre length of speaker wire and a 3.5 mm jack connector to make a temporary long-wire antenna.

In my experience, there are roughly 3 tiers of Tropical and Tropical Band DX on short wave. There’s the bottom tier of stations which with a decent portable and a few metres of wire can be readily heard in the UK on a Dxpedition – and at home with a magnetic loop antenna, for example and a good quality table-top receiver or SDR. Amongst this group of signals I would include Rádio Clube do Pará, Brazil on 4885 kHz, Radio Difusora Roraima on 4875.3 kHz, Emisoras Pio XII 5952.5 kHz, Radio Santa Cruz, 6134.8 kHz etc. etc. On the next tier are tropical stations that are really difficult to hear in the UK – but can be heard with good propagation and good equipment. This group includes Radio Aparecida on 6135.2 kHz particularly, Rádio Educação Rural on 4925.2 kHz, Radio Tarma Internacional on 4774.9 kHz, Rádio Evangelizar (formerly Radio RB2) on 6040.7 kHz etc. There are many more examples from these two groups I could use, but you get the picture. Lastly, there is a tier of stations that are very rarely or never heard in Europe, irrespective of equipment or propagation. Often these stations operate with low TX power which makes them extremely difficult to copy anyway – and that leads to ambiguity farther as to whether they are even on-air. Furthermore, some of these stations broadcast very irregularly, which makes copying them even more of a lottery.

My mainstay travel receiver, the brilliant Eton Satellit..two-time veteran of South American DXing

In this context, a month in Northern Brazil was a useful timescale for surveying the Tropical Bands and geographically tropical stations for the presence of very rare signals. Fortunately, over many hours of listening in Rio Capim with the Eton Satellit and mostly the Bonito MegActive MA305 antenna, I manged to record six signals that are very rarely heard outside of South America. The list of stations follows below, complete with the antenna arrangement. Further below you will find embedded reception videos and text links to the same videos on the Oxford Shortwave Log YouTube channel. Please take the time to watch the videos and note the comments made by some of my subscribers with local knowledge. In particular, Rádio Gaúcha and Rádio Canção Nova on 4825 kHz are very irregular broadcasters and therefore I was fortunate to be in the right place, at the right time to copy their signal. More luck came my way with the reception of Radio Sora de Congonhas on 4775 kHz – made possible because of a total power cut on site, reducing noise effectively to zero (I was indoors at the time). I, personally, never heard anything else other than Radio Tarma, Peru on or around 4775 kHz – itself something of a rarity, except when conditions are very good.

In conclusion, I have to say, once again, the DXing credentials of the Eton Satellit and the Bonito MegActive MA305 USB-powered antenna are clearly demonstrated here. The perfect travelling companions for the serious DXer and broadcast band listener alike, I had no issues getting through security at any of the airports and their combined weight is unnoticeable in a fully loaded backpack. I definitely recommend both products. It’s also worth noting that if you’re travelling to a relatively remote location, even with modest equipment, you might be able to copy rare signals that will provide good information to the rest of us trying to hear those same signals from 1000’s of km away. I will be returning to Rio Capim early in 2018 and I’m seriously considering taking my Perseus SDR with me. A superbly sensitive and selective receiver with noise reduction that actually works, it opens up the possibility of even more exotic DX on that trip.

As always, thanks for watching/listening/reading and I wish you all excellent DX and Season’s Greetings. 73!

The list of exotic catches and antennas utilised:

Radio Apintie 4990 kHz, Suriname – Bonito MegActive MA305
Radio Cançao Nova 9675 kHz Sao Paulo – 20 metre long-wire
Radio Verdes Florestas 4865 kHz, Cruzeiro do Sul – Bonito MegActive MA305

Keith is impressed with the Digitech AR-1780

3 Replies

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.
