Preview: The C. Crane CCRadio3 AM/FM/WX and 2 Meter receiver

In early January 2019, C. Crane sent me a pre-production unit of their latest radio for evaluation: the C. Crane CCRadio3.

Since I received the CCradio3, I’ve had it on the air and have been evaluating it in real-life listening conditions, searching for any potential quirks that C. Crane should address before a full production run of the radio hits the market.

Yesterday, C. Crane announced the CCRadio3 in their email newsletter:

So now, finally, I can break my silence to inform you all about this latest iteration of the venerable CCRadio. And, indeed, I have a lot to tell…

CCRadio3 Preview

What follows is a preview of the CCRadio3 based on my time with the pre-production unit. I will not refer to this as a “review” of the CCRadio3, since this is a pre-production unit.  I’ll obtain a first production run unit when available and post a full review at that time.

In the meantime…here are some of my impressions based on the pre-production unit, organized by feature.

Bluetooth

What’s new with the CCRadio3? The major upgrade is the addition of Bluetooth connectivity. In fact, that’s the only obvious upgrade other than the fact you can now toggle between AM/FM band rather than scroll through all the bands on one band button.

With Bluetooth connectivity, you can pair with your smart phone, tablet, laptop, PC or any other Bluetooth device, and use the CCRadio3 as your Bluetooth speaker.

How many radios do you know that include simple operation instructions on the chassis? Very simple.

The pairing is incredibly simple and Bluetooth connectivity most impressive. I find that no matter where I go in my house, the CCRadio3 maintains a solid Bluetooth connection with my iPhone. Most of my other Bluetooth devices will lose connectivity if I put a couple walls between my iPhone and the receiver, but not the CCRadio3.

Audio

The internal speaker on the CCRadio3 provides room-filling audio with clear, rich fidelity. The separate bass and treble controls do help tailor the sound based on the audio source. It reproduces music brilliantly in FM and Bluetooth modes.

2 Meter Ham Radio Band

One unique feature of the CCRadio series is 2 meter ham band reception. This is a great way to monitor local amateur radio repeater traffic.

In truth, I’ve spent comparatively little time with the CCRadio3 on 2 meters thus far, having focused instead on the AM/FM and WX bands, but I have verified that I can receive local repeaters and the squelch functionality is quite effective.

I’ll spend more time on this band in my upcoming full review.

Weather Radio (WX) Band

The CCRadio3 can receive all seven NOAA/Environment Canada radio frequencies.

And here’s something that really surprised me: this pre-production CCRadio3 has the best weather radio reception of any radio I’ve ever tested to date. Normally, at my home, I can receive two NOAA stations with the average weather radio. The best of my weather radio receivers might hear a total of three. The CCRadio3, with antenna fully-extended, can receive five NOAA stations! I can almost WX DX with this rig!

I’m so pleased C. Crane places an emphasis on WX band performance. Their CC Skywave and CC Skywave SSB also have best-in-class weather radio reception.

Like the CCRadio2E, the grab handle is built into the back of the radio.

The CCRadio3 uses four D cells for battery operation which should yield about 120 hours of AM broadcast listening at moderate volume.

FM

Thus far I’m very pleased with FM performance. I’ve noted that the CCRadio3 receives all of my local and distant benchmark stations with ease. I believe it would certainly be an FM benchmark receiver. As I mentioned earlier, audio fidelity is excellent via the internal speaker.

AM/Mediumwave

I consider the CCradio3’s predecessor––the CCRadio2E––to be one of the finest AM broadcasting listening portables currently in production. I’ll admit that when I heard the CCRadio3 added Bluetooth, I feared somehow that would equate to possible noise somewhere in the audio chain…Fortunately, this fear was entirely unfounded. In fact, looking at the CCRadio3 announcement, I note that C. Crane took this concern seriously:

“The CCRadio 3 is one of the few high-performance radios with Bluetooth® that has no detectable noise and some of the best reception available.”

When I first turned on the CCRadio3 and tuned to the AM band, I did what I always do when testing mediumwave performance: In the early morning, as the sun was rising (i.e., grey line propagation), I tried to pull my benchmark station––WAIZ, a 1,000 watt station about 95 miles away as the crow flies––out of the muddle. The CCRadio3 was able to do it; in fact, I could hear the station’s morning crew doing their “Wacky Wake-Up” shenanigans. Turning the radio body, I also gathered, rather quickly, that the CCRadio3’s Twin Coil Ferrite Bar antenna does an excellent job of nulling out unwanted stations.

An impressive start of the evaluation.

Comparing the CCRadio3 with Panny RF-2200

Looking around SWLing Post HQ, I picked up my recently re-capped and refurbished Panasonic RF-2200. I wanted to see how the CCRadio3 would stack up against what I consider one the finest AM broadcast portables ever produced…

I’ve tested the CCRadio3 and ‘2200 at various locations––in the morning, midday, and at night––and can say that not only does the CCRadio3 give the RF-2200 a run for its money, but it even outperforms the RF-2200 at times, in terms of weak station intelligibility.

In fact, I think the CCRadio3 may possibly have a very slight edge on the RF-2200 in terms of sensitivity, as well.

However, note that there are two factors that make this comparison a tough call:

  • First of all, I find that the RF-2200’s AGC is smoother than that of the CCRadio3––the peaks and dips in audio are not as strong when listening through AM flutter. Most of the time, this makes it a little easier for me to discern weak signal audio. I believe the CCRadio3’s AGC and soft mute may be making the troughs in AGC a little deeper, as well. It would be amazing if C. Crane could allow users to disable soft mute like recent Sangean models have.
  • Secondly, the RF-2200 has two AM bandwidth settings: narrow and wide. I almost always use the RF-2200 with the wide bandwidth setting. I find the narrow filter is a little too narrow unless I need it to block an adjacent signal.  In general, I use wider AM filter settings than many DXers because I find that the filter between my ears does a better job of discerning signals with a little more audio information.

The CCRadio3 has only one bandwidth. I’m guessing––based purely on my listening experience––that it’s 4 to 6 kHz in width.  (I’ll try to confirm this with C. Crane).   Obviously this is narrower than the RF-2200’s wide filter. In side-by-side comparisons, the RF-2200’s AM fidelity therefore sounds much richer, especially when music is involved.

That this is so really shouldn’t be a surprise, as the Radio3 and its predecessors were designed around spoken word intelligibility––in other words, making it easy for the listener to understand what’s being said. And, frankly, it works. Most of the time, I find that the CCRadio3 does a better job of making weak signals “pop” out of the static. It’s a little easier catching weak signal station IDs with the CCRadio3, even if you have to listen through a more active AGC/soft mute tug.

So…is the CCRadio3 (at least, this pre-production unit) better than the RF-2200 at weak signal DXing? In some respects, yes. In others, not quite. Yet the fact that it can even compare with the RF-2200 speaks volumes…no pun intended. I would have never guessed that it would have a sensitivity edge on the RF-2200.

Of course, the CCRadio3 has both AM antenna and ground terminals.

I made a few early afternoon videos comparing the CCRadio3 with the RF-2200. In the first video, I’m tuned to a station approximately 20-25 miles away. You’ll note how the RF-2200’s audio fidelity, with the wide filter engaged, is hard to match:

In the second video, I’m tuned to 1290 AM (WHKY), a 50,000 watt station about 95 miles away. [Note that I erroneously give an inaccurate mileage figure in this video; not sure what I was thinking!  Sorry about that, folks.]

Click here to view on YouTube.

In the third video, I’m tuned to 630 AM (WAIZ), again, a 1000 watt station about 100 miles away. As you can imagine, it’s very weak and both radios struggle to receive any intelligible audio through the ocean waves of fluttering radio jumble. [Again, please ignore the distance I give in the video; this station is actually a little over 95 miles away.]

I also did a late afternoon comparison video around sunset using one of my favorite AM radio stations ever: CFZM in Toronto–about 980 miles distant. Here’s the video:

Click here to view on YouTube. 

In these video comparisons, the radios are nearly side-by-side.  I found this had little to no effect on reception. When comparing these radios off camera, I had them spaced at least 40″ apart and always, of course, oriented the antennas identically.

Conclusion

Again, this is merely a preview of the pre-production unit of the CCRadio3. I thought I’d touch on reception and a few of the key points that might help some of the CCRadio3’s early adopters make a purchase decision. I have yet to do testing with headphones or external antennas and still wish to compare it with even more radios, to make my review as thorough as I’d like.

And I’m really looking forward to reviewing the production unit of the CCRadio3, because this pre-production receiver has certainly surpassed my expectations!

This latest iteration of the CCRadio should remain king of AM radio reception, compared with any other portable radio currently in production.

C. Crane has announced that they have a very limited number of first-production-run units available for order right now.  If you order one, use the coupon code CC3B19 at checkout, so that, as the above ad suggests, you can snag it for $179.00–$20 off the future retail price. I suspect this first run will sell out fast.

Radios: What are your daily drivers?

Many thanks to SWLing Post contributor, John C., who writes:

“Hi Thomas, I love [the SWLing Post] and have been meaning to thank you for all of the amazing reviews. Truly a treasure trove. But as I contemplate my next radio purchase I would like to know what radio you use more than any other. In other words…what’s your daily driver??? Enquiring minds want to know! Thank you. – JC”

Thanks for your question and the kind compliment, John.

Your inquiry is one I get quite a bit, so I hope you don’t mind if I share my response here publicly.

First of all, I should state that I don’t have a single “daily driver.”

Since I evaluate, test, and review radios I spend a lot of time with a variety of new receivers and transceivers.

I’m currently evaluating the Radiwow R-108, so it goes with me pretty much everywhere since I like to test receivers in a variety of settings. I’m also packing the Tecsun PL-310ET and the CC Skywave so I have units to compare with the R-108.

My Daily Drivers

Still, there are a number of radios in my life that get heavy use. Here’s my current list based on activity:

For Travel

When I travel, I reach for my favorite multi-function ultra-compact shortwave portable. In the past, I would have reached for the Grundig G6, the Sony ICF-SW100, the Tecsun PL-310ET, the Digitech AR-1780, or the C. Crane CC Skywave, Currently, I reach for the C. Crane CC Skywave SSB.

When I travel, I try to pack as lightly as I can–perhaps some would even call me a borderline travel minimalist. For example, when I fly to Philadelphia later this month for the Winter SWL Fest, I will take only one piece of luggage, a “personal carry-on” item: the Tom Bihn Stowaway, a pack the size of a small laptop bag. The Stowaway will contain my iPad, cords/accessories, and all of my clothes and toiletries for about 5 days of travel. As you can imagine, there’s not a lot of spare room in there for radio gear (quite the understatement).

I’ll still have room in my bag for the CC Skywave SSB, though, because the receiver is so compact. In addition, it’s a little “Swiss Army Knife” of a radio which covers the AM/MW, Shortwave, WX, and AIR bands.  It also has SSB mode and uses common AA batteries. The Skywave SSB is a welcome travel companion.

For Portable Shortwave DX

When I head to a park or go on a camping trip with the goal of doing a little weak signal DXing, I reach for a full-featured portable. In the past, I’ve relied heavily on the Tecsun PL-660 or PL-680, the Sony ICF-SW7600GR, and the Tecsun PL-880.

After acquiring the amazing Panasonic RF-B65 last year, it has become my choice full-featured portable. Of course, the RF-65B hasn’t been in production for ages, but thanks to a number of friends/enablers (including Dan Robinson and Troy Riedel) I finally found one for an acceptable price on eBay.

I’ve been incredibly pleased with the RF-B65’s performance and feel like I got a decent deal snagging one in great shape for less than $200. Only a few months prior to my purchase, it was hard to find good units under $300. Click here to check current prices, if interested.

For Morning News and Music

Since my staple morning news source, Radio Australia, went off the air, I spend a lot more time in the mornings listening to Internet radio mainly because I like listening to news sources that no longer, or never have, broadcast on the shortwaves.

Without a doubt, my favorite WiFi radio is the Como Audio Solo. I use it to listen to the CBC in St. John’s Newfoundland, The UK 1940s Radio Station, RFI MusiqueABC Radio Sydney, and a number of other news and music outlets.

The Como Audio Solo also serves as an audio feed for my SSTran AM Transmitter which then allows me to listen to all of this excellent content on 1570 kHz with vintage tube radios such as my Scott Marine SLR-M, my BC-348-Q, and my Minerva Tropicmaster.

For Mediumwave DXing

Without a doubt, my favorite radio for mediumwave/AM broadcast band DXing is the Panasonic RF-2200.

I mentioned in a previous post that my buddy Vlado (N3CZ) recently repaired, cleaned, and calibrated one of my RF-2200s.

Let’s just say that Vlado worked his magic and my RF-2200 now operates and performs like a brand new unit. Seriously. It’s simply unbelievable.

Not only does the Panny ‘2200 provide benchmark MW performance, it’s simply a pleasure to operate. It also produces some of the richest AM audio you’ll ever hear from a portable radio.

Of course, the ‘2200 hasn’t been produced in decades, so you’ll have to search for used ones on eBay, at hamfests, or through your favorite radio classifieds.

And, yes, I still need to finish a Part 2 blog-post about the ‘2200 repair–once I get a few details and photos from Vlado, I’ll post it!

Your Daily Drivers? Please comment!

Keep in mind that my “daily drivers” change quite a bit–the ones listed above are my current favorites and have been for a year or more.

So now that I’ve shared my daily drivers, I hope you will, too!

Is there a particular radio you reach for more than any other?  Please comment and tell us why it’s your favorite!

Sangean DT-800 Review: AM/FM/Weather ultra-compact radio

Two months ago, SWLing Post reader Paul Adler wrote to ask:

“Any reviews and comparisons of the Sangean DT-800?”

The Sangean DT-800? This caught my attention, as I wasn’t, at the time, familiar with this recent addition to the Sangean product family.  So I promptly began investigating the new product, and checked out the manual; I found it has a few features that really intrigue me, namely:

  • The ability to turn off soft muting
  • The ability to internally recharge NiMH AA batteries
  • Multiple bandwidth on AM and FM
  • Weather band with weather alerts
  • FM RDS
  • No telescoping antenna––rather, an included wire antenna

In my mind, these features seemed to set it apart from other similar portables.  And with the ability to defeat the soft mute, I wondered if it could make for a formidable Ultralight DX radio?

I contacted Sangean, and they kindly sent me a review sample of the DT-800. It comes in two chassis colors: standard black and and a bright fire yellow. I chose yellow, which makes it easier to spot should this handheld be lost or dropped in an outdoor setting.

Thanks for the suggestion, Paul!

Giveaway!  By the way: since this is a product sample and was sent to me free of charge, I’m going to give it away to a lucky SWLing Post Coffee Fund or Patreon supporter next week, just to say thanks!

Now, let’s get on with the review…

Initial impressions

As with almost all Sangean products, the DT-800 arrives as a complete package, with all accessories. Inside, you’ll find the radio, a full-length multi-language owner’s manual, a warranty card, an AC adapter (with in-line RF chokes, nice touch), in-ear headphones, an external wire antenna, and a belt clip.

The DT-800 fits nicely in the hand, and the matte finish on the sides and bottom of the radio make gripping it quite easy, lessening the chance of dropping or losing the unit.

The front panel is simple: five multi-function preset buttons and a Page/Menu button. All of the buttons are tactile and have a matte finish, as well; they feel of good quality and have a great response.

The right side of the radio (see side view, above) has a tuning/select up/down jog switch, a mechanical keylock button and a MicroUSB DC in port.

On the left side of the radio (see left side view, above) you’ll find the volume up/down buttons and a stereo/mono/speaker mechanical switch which you can use to switch between the internal speaker and headphones.

On top of the radio (above) you’ll find the power button, band selection button and the headphones port, which doubles as the external antenna port.

On the back of the radio you’ll find the DBB bass-boost slider switch, the battery compartment, and a belt clip.

One thing you’ll quickly notice is a lack of any telescoping whip antenna. Instead, the DT-800 ships with a wire antenna that’s almost three feet long. I suspect that this is the same type of FM antenna that shipped with the Sangean WR-7 (click here to read review).

Design/Ergonomics

All in all, I’m very pleased with the DT-800’s design: it fits well in the hand, the buttons and controls are easy to use, and it’s small enough––and flat enough––to easily slip in a pocket, go-bag, or carry-on. A great portable for one-hand operation. It’s also lightweight, even with the batteries inserted. Truly, this appears to be a quality little radio.

Tuning the DT-800 is a simple process: simply utilize the up/down rocker switch on the right side of the radio to increase by specified frequency steps (selectable 50/100 kHz FM or 1/9/10 kHz AM), or push and hold it in one direction to skip across the band. While the DT-800 does mute between frequencies, it’s not annoying––in fact, muting is brief and audio recovery is rapid so you can actually carry out meaningful band-scanning, actually hearing stations between the steps. If you press the rocker switch, it will initiate an auto-scan in the direction you’re tuning.

While the DT-800 lacks a keypad for frequency input (in truth, I would not expect such a thing on a walkman-style receiver)  it does make tuning to your favorite stations quite easy with 20 FM, 20 AM, and 5 WX presets. Saving a station to memory is truly a breeze: simply select the page you’d like to save it to, then press and hold the preset button to save it to one of the numbered presets. Really, it couldn’t be easier.

To change the volume on this radio, you use rocker buttons on the left side of the radio to increase or decrease volume up to 25 levels. I particularly like the fact that level 1 is very quiet and 25 is as loud as you would ever want from a small radio. I mention this because, in the past, I have reviewed radios that had coarse volume steps, and the lowest setting is louder than I prefer: not so with this little rig.

Entering menu items on the DT-800 is quite easy, too.  Some are accessed by pressing and holding the Page/Menu button and then cycling through and selecting items with the tuning up/down switch. Others are accessed by pressing and holding the Page/Menu button, then selecting one of the five buttons on the front panel (note that each menu function is listed below the numbered button).

The DT-800’s display is backlit and large, thus very easy to read at any viewing angle.

AC Adapter

I can’t think of the last time I gave an included AC adapter its own subheading in a review, but the DT-800 power supply deserves one.

Not only does the DT-800 ship with a power supply (AC adapter), but it’s a quality one: the cord jacketing is thick and feels exceptionally durable––and though I’m not going to cut it apart to find out, I expect the wiring within it is a heavier gauge, as well. This adapter also has no less than two in-line RF chokes.

In a day and age when included “wall wart” power supplies are often of the cheapest quality and spew so much radio interference that they render attached receivers useless, the DT-800 adapter is a very welcome addition to this radio’s kit.

Well played, Sangean! I hope other radio manufacturers follow your lead.

Batteries

Lately, it seems most new radios are being designed to accommodate slim Lithium Ion battery packs. So, another welcome sight was opening the DT-800’s battery compartment to find slots for two AA batteries.

While Li-ion batteries have advantages in terms of weight and size, I prefer AA batteries for pocket and travel radios, as AA batteries are so ubiquitous on this planet and are available in all but the most remote regions of the world.

And better yet? You can internally recharge NiMH batteries with the DT-800. The DT-800 ships with a default setting for alkaline batteries. But to internally recharge NiMH batteries, simply open the battery compartment and change the battery type switch from “Alkaline” to “NiMH.”

This is an amazing and useful feature, but just be sure if you ever use the NiMH internal recharging function and then switch to alkaline cells, that you change the battery selection switch back to the alkaline setting. You certainly wouldn’t want the DT-800 to attempt recharging your alkaline cells!

As you can see in this photo, I’ve been using Panasonic Eneloop NiMH batteries in the DT-800. I use a special charger for Eneloops, so have kept the battery selection switch set to alkaline so the DT-800 doesn’t attempt to charge them. I might even put a small piece of colored tape on the switch to keep it in place for now.

Audio

The audio via headphones? It sounds great on the DT-800!

Indeed, the DT-800’s included in-ear style stereo earphones are a cut above most other included-with-a-product earphones, and as a result, produce more pleasant audio.

With the headphones engaged, FM offers selectable mono or stereo; mono, of course, makes marginal stations more stable since the stereo lock isn’t struggling.

Like the Walkman radios of days gone by, the DT-800 uses the headphone cord as an antenna when it’s attached. If you’re using the internal speaker, you’ll need to attach the included external wire antenna for FM and WX bands.

The DT-800 internal speaker produces decent audio for the size of the radio. The speaker is tiny, so the audio is somewhat tinny (narrow in range) when listening to music. But the DT-800 also has a DBB (Dynamic Bass Boost) switch––engaging this will increase the bass response a bit, most noticeable when using headphones.

Performance

The DT-800 has three bands: FM, AM (mediumwave), and WX (weather). Let’s take a look at each.

FM Band

The DT-800 sports a unique feature on the FM band: the ability to select between a wide or a narrow filter. Since the dawn of the DSP chip, many a portable radio has enjoyed selectable bandwidth filters, but it’s a rare portable that has FM filters. I do pretty much all of my FM listening with the wide filter engaged, but if you live in an urban area with a crowded FM band, choosing the narrow filter, even if it compromises audio fidelity a bit, will give you better selectivity. Nice touch, Sangean!

In terms of sensitivity, with the external antenna inserted, I’ve been very pleased with the DT-800. It receives all of my benchmark FM stations. With headphones inserted (used as an antenna) and stereo engaged, it has ever-so-slightly less sensitivity than several of my other DSP portables. With the headphones inserted and FM in mono, I find that it’s on par with––or surpasses––my other reference DSP portables.

Here’s a little wrinkle, though: when listening with the internal speaker, you must insert the external wire antenna to use this receiver on FM. Without the external antenna, sensitivity decreases by a good 70-80%, as you essentially have no antenna. If you live in an area with strong FM stations, you’ve nothing to fear, but if you live in a rural area, you’ll certainly want to keep that wire antenna handy.

On one hand, the wire antenna is easier and more flexible to deploy than attached telescopic antennas, which can be bent or broken. But on the other, an external wire antenna is just another item you’ll need to pack and take along with the radio if you plan to listen via the internal speaker.

If you plan to listen with headphones, however, no worries! I find the sensitivity with headphones inserted to be just as effective. In fact, instead of taking along the wire antenna you could bring the included headphones, and they’ll double as an external antenna while listening via the internal speaker. In my tests, the headphones performed about as well as the external wire antenna.

My advice? If you purchase the DT-800, either keep the small wire antenna or a pair of headphones nearby to insure you’re getting the best FM reception.

Weather Band

The same notes above about the necessity of an external wire antenna apply on the weather band as well as the FM band.

With the wire antenna or a set of headphones connected, weather radio reception is good. I was able to receive both of my local NOAA weather reference frequencies.

To be clear, the DT-800 is not as sensitive as my C. Crane CC Skywave or CC Skywave SSB––which are truly WX band benchmarks––but it will likely receive your local NOAA or Environment Canada broadcasts as well as most other weather radios.

The DT-800 also includes a Weather Alert feature, but as Sangean notes, you should only use this feature while the radio is plugged into mains power, as it will drain batteries about as effectively as if you were listening to an FM radio station.

AM/Mediumwave Band

If there’s a weak point on the DT-800, I would say it’s the AM band.

Don’t get me wrong: at first blush, the DT-800 looks like a little Ultralight DXing dream, as it’s loaded with great features, such as:

  • multiple bandwidths (wide/narrow),
  • 9/10 kHz spacing,
  • well-balanced AGC (auto gain control),
  • as well as the ability to turn off soft muting.

Yes, the DT-800 has the ability to disable soft mute. Thank you, Sangean! So far, Sangean seems to be one of the only radio manufacturers that enables this DSP chip option in their product line. Another receiver with the ability to disable soft mute was the Sangean ATS-405 (check out our ATS-405 review). I wish other radio manufacturers would do the same because soft mute is what often makes listening to weak mediumwave signals so fatiguing. With soft mute disengaged, weak signals enjoy better audio stability as they’re not fighting to stay above the muting threshold.

But, I’m sorry, DXers: unfortunately, the DT-800’s weakness on AM is the same as the ATS-405 on AM (and shortwave): a higher-than-average noise floor. Somehow, internal noise is being generated and not being contained by shielding and grounding.

I made a short comparison video to demonstrate the noises heard via the DT-800. Before you ask: yes, these noises are present regardless of radio location, or whether or not there are other radios nearby. In addition, I made this video on a folding table far away from my house or any other potential sources of noise (with the exception of my iPhone which was used to make the video). This is the same low-noise spot I use to do comparison tests of all my portable receivers:

Click here to view this video on YouTube.

As I note in the video, the noise floor isn’t consistent across the band––some parts are lower, other parts higher. One of the noise peaks is around 1600 kHz which, unfortunately for me, is where my favorite local AM station resides.

So is this a deal-breaker?  No…not necessarily.  For the casual AM radio listener––a listener primarily focused on listening to local AM stations––I think the DT-800 will please. In fact, I might not have noticed the elevated noise floor had I not: 1) listened to weaker AM stations, and 2) compared the DT-800 with other radios.

Since I’ve been using and listening to this radio for the better part of a month, I can state with confidence that most of my other portables outperform the DT-800 on mediumwave. I compared it with these rigs:

  • Sony ICF-S10MK2
  • Tecsun PL-310ET
  • CC Skywave
  • CC Skywave SSB
  • Radiwow R-108

To be clear, I believe the DT-800 has average MW sensitivity for a radio this size, but the noise floor sort of spoils any hopes of doing marginal or weak signal work, thus also making that awesome soft mute toggle less effective.

If you pair the DT-800 with a loop antenna like the AN200, which I highly recommend doing, it will help those weak signals rise above the noise. Otherwise, if your primary goal in purchasing the DT-800 is to listen to mediumwave, I regret to say, you might want to take a pass on this one.

Summary

Every radio has its pros and cons. Each time I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions and observations. Here’s the DT-800’s list, from the first moments I turned it on, to the time of writing this review:

Pros:

  • Great overall performance on FM
  • Quality construction and thoughtful ergonomics
  • Both clock and alarm for the traveler
  • Ability to switch between FM stereo/mono with headphones in use
  • Wide/narrow AM and FM filters
  • NiMH AA batteries can be recharged internally [make sure switch inside battery compartment is set to “NiMH”]
  • FM RDS (one mode)
  • Mechanical keylock switch
  • Ability to disable soft mute (other radio manufacturers take note!)
  • Small internal speaker providing quite decent audio
  • Comprehensive gear package includes radio, manuals, quality earphones, quality AC adapter, wire antenna
  • DC port is standard MicroUSB
  • Belt clip
  • Built-in speaker
  • Dynamic Bass Boost

Cons:

  • While listening via the DT-800’s internal speaker without antenna wire or headphones inserted: FM performance is lacking, while weather radio performance is very much lacking
  • AM band: Noise floor is higher than on comparable radios

Conclusion

The Sangean DT-800 is a solid little radio: it’s simple to operate and feels like a quality piece of kit. It’s perfect for hiking, or any sport or task where you’d like one-hand operation.

The DT-800 also has a surprising amount of features and customization through the menu settings––much more than one would expect––which puts it firmly into what I would call the “enthusiast-grade” radio category.

It’s for this reason that it’s a bit disappointing AM reception on this Sangean isn’t better.

The DT-800 has a lot of icing on the cake, otherwise: FM RDS, the ability to internally recharge AA batteries, built-in speaker, Dynamic Bass Boost, multiple bandwidths on AM and FM, the ability to disable soft mute–all of these are essentially pro features.

So, if you’re looking for a quality portable radio primarily for FM and WX band listening and perhaps catching the odd local AM broadcast, the DT-800 is a great choice.

Are government shutdowns a potential haven for pirate radio stations?

SWLing Post Bill Patalon sent me this piece from the ARRL stating that amateur radio applications have been on hold at the FCC as most of the agency has been closed in the US government shutdown. It appears the government will reopen now, at least for the next three weeks.

Thinking about the closure of the FCC and its effect on licensed operators, also made me think about unlicensed radio operators: a.k.a. pirate radio stations.

Are government shutdowns a potential broadcast opportunity for pirates that might not otherwise take to the air?

I’m curious if anyone noted new shortwave or FM pirate stations during the US government shutdown. Did the respite from FCC enforcement bring anyone out of the woodwork?  Please comment!

PS: Can you do us a favor? In comments, please stay on topic (radio) and refrain from political arguments.

The Knitted Radio: An FM radio transmitter sweater

Many thanks to SWLing Post contributor, Paul, who shares a link to this fascinating maker/art piece from designer Irene Posch:

The Knitted Radio is an installation piece that manifests how to knit a sweater that is also a FM radio transmitter. The tactile centerpiece is a functional electronic object knitted out of ordinary wool and commonly available conductive materials. The accompanying knitting instructions, to be published in a knitting magazine, allows the reproduction of the electronic object by an alternative maker group.

The piece is part of a larger investigation into using traditional textile crafting techniques to create electronic components and devices from scratch. The critical question is whether ‘what’ one makes is really more important than ‘how’ one makes things. Industrial technology research is mostly driven by the desire to invent the next killer application, whereas artistic research holds the chance to question implications. By exploring alternative production procedures, we might be able to reveal skills, techniques and materials that have been uncharted, undervalued, or decisively left out of popular demand.[…]
