In the pipeline: a review of the Sangean HDR-14 portable AM/FM HD radio

Based on readers correspondence, the most anticipated non-shortwave radio to hit the market this year might be the Sangean HDR-14 AM/FM HD radio.

Sangean sent me a sample evaluation unit and I’ve had it on the air since taking delivery last week. I’m starting to put the elements of my HDR-14 review together while also writing Part 2 of my SDR primer for The Spectrum Monitor magazine (Part 1 was published last week). Indeed, I’ve a total of five reviews and evaluations on my desk right now–!

So far, I’m impressed with the little HDR-14. If you recall my review of the Sangean HDR-16, I mentioned that one of my benchmark distant HD FM stations is WFAE 2–its transmitter is a full 101 miles from my home and I’m well outside even the the fringe reception area.

The HDR-14 has a unique back stand: a small foot that swivels out of the base of the chassis.

I’m pleased to note that on more than one occasion, I’ve gotten a reliable HD lock of WFAE from my porch. A most positive sign!

Over the next three weeks, the HDR-14 will be travelling with me and I hope to even snag an AM HD station if all goes well.

I can tell you already that I’m as pleased as punch Sangean gave the HDR-14 a total of 20 AM and 20 FM memory presets. The larger HDR-16, in contrast, only has 5 AM and 5 FM presets.

Look for my review of the HDR-14 on the SWLing Post in the coming weeks. If interested, follow the tag: HDR-14

I’ve noted that both Universal Radio and Amazon.com (affiliate link) have the HDR-14 in stock and shipping. Universal’s price is $79.99 plus shipping and Amazon’s price is $88.67 including shipping.

UK digital radio listening now eclipses analog according to study

(Source: Radio Mag Online via Marty Kraft)

LONDON — In the United Kingdom, the use of digital sources for radio has reached 50.9%, up from 47.2% a year ago, accounting for the majority of all listening for the first time, according to RAJAR Q1 2018 data.

“With the 50% digital listening threshold now met, it is anticipated that the UK government will undertake a review to assess digital radio progress and determine next steps in due course,” according to a Digital Radio UK press release.

Digital listening share is comprised of listening across all digital platforms: DAB in homes and in cars, apps and online (which includes the growing number of smart and voice-controlled speakers) and DTV — and this is the first time that listening to digital has been greater than analog platforms — FM and AM.

[…]The UK’s three leading radio broadcasters — the BBC, Global and Bauer, which collectively account for over 90% of UK radio listening — are “fully committed to delivering a digital future for radio and look forward to working with government and the supply chain to continue the transition to digital radio.”

RIP Dr. Byron St. Clair: Father of low-power FM

(Source: TV Technology via Bill Patalon)

Dr. Byron St. Clair, president emeritus of the National Translator Association, died May 20 in Denver of brain cancer. He was 93.

St. Clair, who served as president of the National Translator Association for 19 years, is known as the “father of translators, LPTV and low-power FM,” the association said.

He worked to serve those living in the mountainous rural western United States with broadcast service and in so doing created a new class of over-the-air broadcasting, which has grown to more than 4,000 stations that serve millions of people.

“Byron was a friend and mentor to all, a man of immense intellect, wisdom, ethics, kindness and vision,” said NTA President John Terrill.[…]

A review of the supercompact Sangean WR-7 FM Radio and Bluetooth speaker

Folks have been known to say that good things come in small packages.  And, do you know what? They’re sometimes right. [Spoiler alert: This review features a good thing which comes in a small package.]

I’ve been in the process of evaluating some pretty complicated pieces of communications equipment lately. So when Sangean approached me a few weeks ago and asked if I would check out their latest FM radio and Bluetooth speaker––a comparatively simple piece of kit––I thought, Well, why not? Because while I prefer “enthusiast grade” radios, sometimes it’s nice to check out something super-simple and purpose-built from a company I’ve grown to trust. Plus, it didn’t hurt that Sangean actually bothered to include FM radio on what would otherwise simply be just another Bluetooth speaker.  Ah, yes; a worthy addition.

Sangean dispatched the sample radio and I received it within a few days. I was expecting something roughly on the scale of a Tivoli Model One.  Instead, when I opened the box, what I found was a radio only slightly larger than my diminutive  Muzen OTR, a little radio that fits the palm of your hand. To be fair, it could only be called…cute.

By my measurements, the tiny Sangean WR-7 is about 2 1/2″ tall, 4 5/8″ wide, and 3″ deep (if you include the tuning knob in that last dimension). It’s mini by almost any standard.

For this photo I placed it next to my handy XHDATA D-808 compact radio.  And here’s how they compare:

Though wee, the WR-7 feels weighty (14.4 oz), solid, and substantial in the hand.

Turns out the chassis is solid––solid wood. Sangean has two options: walnut and dark cherry. Of course, my sample is a black version which may appear later in the year.

And the WR-7 is as simple to operate as it is to…well, hold in your hand. There’s one knob to turn the radio on and select the source (FM, Bluetooth, or the analog AUX input), and another knob for volume.  Just as these photos show.

The tuning knob is the largest knob and moves fluidly across the dial. The analog dial is white with black frequency markings, and is backlit. From my tests, the FM dial is fairly accurate, although the frequency marking steps are a bit odd: 2 or 3 MHz increments starting at 87.5 and ending at 108 MHz.

There is a green LED lamp hidden behind the speaker grill that acts as the FM signal strength indicator. This LED turns blue when in Bluetooth mode.

Performance

There’s not a lot to report on here and, perhaps, that’s why I halted my other evaluations to fit this one in. This radio needs no owner’s manual (though it does ship with one). All you need is a USB charging cable––yep, the same type that likely charges your mobile phone.  And, of course, it ships with one. It also ships with a lightweight cloth-like carrying bag.

You might have noticed that the WR-7 doesn’t have a telescoping whip antenna.  That’s okay, because it also ships with an external wire antenna (which I actually prefer on this type of mini tabletop radio).

The WR-7 has an internal 2600 mAh Lithium-Ion Battery that provides this tiny rig with up to 36 hours of operation between charges. While I haven’t tested this claim yet, I can tell you that its battery life is incredibly good––especially acknowledging that the audio amplifier must be using quite a bit of the battery.

FM

The WR-7 receives the FM broadcast band from 87.5 to 108 MHz.  While the dial is analog, I know there’s a DSP chip inside because I can hear frequency steps while I tune across the band. There is no muting between frequency steps, so the experience of tuning feels somewhat analog. As I mentioned earlier, the dial layout is a little quirky, but overall the frequency markings are pretty close to accurate. I found my benchmark stations with little difficulty.

In terms of sensitivity, the FM receiver is quite good in the WR-7.  I could receive almost all of my local stations with the external FM antenna connected. Of course, you’ll want to connect the FM wire antenna.

With the external antenna connected, I could receive all of my benchmark distant and weak stations as well on the WR-7. While reception is very good, it isn’t quite as good as on my XHDATA D-808, C. Crane CC Skywave SSB, or Tecsun PL-660––the lock isn’t quite as stable––but I probably could have tweaked this by moving the external wire antenna.

Audio fidelity

Thing is, with even a decent FM signal, you’ll be mighty impressed with the audio fidelity of the WR-7. It easily manages to sound like a radio three to four times its size. Truly, the bass that emanates from this tiny speaker is incomprehensibly deep–only limited by the size of the acoustic chamber.

The sound is rich and room-filling when the volume is turned up.

And speaking of turning up the volume, this is one little radio you’ll probably peg at its highest volume setting from time to time. In fact, I rather wish this radio would allow the volume level to reach even a notch higher…but I expect this was a design choice at Sangean. With the volume turned up all the way, the sound is room-filling, but not distorted. While testing the WR-7, I tuned it to a variety of stations and played a wide range of music through it via Bluetooth: I never noticed bass-heavy songs distorting the audio. I suspect if the volume could be increased even further, the audio would indeed distort a bit.

In short: though you might occasionally turn up the volume on the WR-7 all the way, you’ll be pleased with the results––even across the room!

Bluetooth

I’m not sure what to say about Bluetooth; to me this is a technology that seems to work quite well for wireless connections between mobile devices. The WR-7 has built-in Bluetooth Technology Version 4.1, and it worked flawlessly with all of my mobile devices as well as my shack’s PC.

For a full week, I used the WR-7 as the speaker for my shack computer, and it was most impressive. In fact, it makes for a nice compact external speaker to pair with my SDR applications. AM audio, piped through Bluetooth into the WR-7, is a treat.

For a few nights, I even streamed OTR productions of “Buck Rogers in the 25th Century” with my shack computer, connected to the WR-7 via Bluetooth. The WR-7 was actually in the adjoining room, yet the Bluetooth connection was strong and never dropped the audio. The resulting sound was nothing short of amazing: if you closed your eyes, it almost sounded like a valve set from 1939.

And that’s another thing about the WR-7 worth noting: It’s so small and so simple in design, it fits in anywhere, and isn’t in the least obtrusive, all while filling the room with its warm, rich sound.

Summary

Every radio has its pros and cons. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget some of my initial impressions. Here is the list I formed over the time I’ve spent evaluating the WR-7.

Pros: 

  • Superb, room-filling, rich audio especially considering its very compact package
  • Very good FM sensitivity
  • Internal battery powers it for dozens of hours between charges
  • Easy to recharge via any 5VDC USB source
  • Easy Bluetooth connection and brilliant audio
  • Simple operation

Cons:

  • Volume and selection knobs could be slightly small for some users’ hands
  • Volume range more limited than most, upper volume capped
  • Although it does come with a nice lightweight carrying pouch for traveling, you might wish for a little extra protection in a suitcase or carry-on bag

Radios like the Sangean WR-7 give me hope that consumer electronics might be heading back in what is, in my humble opinion, the right direction: that is, toward quality.

The WR-7 is really a quality piece of kit: it has a solid feel (imparted by solid wood), has an acoustic chamber that produces excellent audio, and you can tell that the FM receiver wasn’t simply an “add-on” feature, as it works quite well.

While you won’t see many radios like this reviewed on the SWLing Post, I’m glad I agreed to take on this one.  It was an fun exercise, and reminded me why I love doing radio reviews: sometimes these digital marvels really surprise me. That, and I’m enough of a radio and consumer electronics geek to bask in the indulgence of pure listening!

Good one, Sangean! Accolades!

“Broadcast Isolation in Japan”–no workarounds?

Many thanks to SWLing Post reader @medmouad who recently shared a link to the following article by Kenji Rikitake at Medium.com:

I’m sure Japan is one of those countries which implement the worst online broadcasting policies.

You cannot listen to Japanese internet radio stations from outside the nation, thanks to the geotagging technology for the IPv4 address; most of the major broadcasting stations do not allow access to their streaming feed outside Japan. This is a huge disservice to the expats, but the broadcasters seem not to care about it at all.

Japan’s geotagging policy against streaming broadcast is even worse within the nation; the telecom ministry enforces prefectural border limits for licensing the broadcast stations, though in some rare cases wider limits are allowed. Japan is regionally divided into 47 prefectures. So you cannot listen to Tokyo radio stations for free when you are in Osaka over internet. And vice versa. Recently a consortium of private broadcast stations, radiko.jp, announced a paid service for cross-prefectural listening of JPY300 (about USD3) per month. Isn’t this a ripoff? And it’s still not accessible from outside Japan.

Japan has a weird article in the copyright law too; the copyright owner can claim the right of making the contents being able and ready to be publicly transmitted. This right is applicable to all transmission media including internet and airwaves. So when you buy a CD, you cannot transmit without the permission of the copyright holder, usually the publisher.

[…]I hope someday I can listen to Japanese radio outside Japan over internet. The day, however, will not come soon.

Continue reading the full article at Medium.com.

If you’re an SWLing Post reader, I’m willing to bet you’re thinking: “Yeah…this is one of the downfalls of radio over the Internet.” We never have this issue with shortwave radio broadcasts since they’re built upon a medium that has, at its very core, no regard for national borders.

Of course, this article focuses on local/regional FM outlets in Japan and the firewalls that keep their online streams neatly contained.

I can’t help but think that there must be workarounds to defeat IPv4 address geotagging within Japan. Perhaps I’m wrong.

I do know that I can easily listen to local AM/mediumwave broadcasters throughout Japan using one of many web SDRs on the KiwiSDR network. Surely the same could be done for FM using a network of web accessible RTL-SDR dongles–?

Has anyone found a workaround? Mark Fahey, you know I’m looking a you!

Despite crackdown, North Koreans seek foreign radio broadcasts

North Koreans continue to seek out foreign radio despite crackdown

Police in North Korea have recently focused their attention on cracking down on listeners of South Korean radio broadcasts in another sign of the government’s dual-approach to warming ties with the South, according to a source inside the country.

Speaking from Ryanggang Province on April 24, a source told Daily NK that “police have begun inspections of households possessing radios,” explaining that one method used to restrict radio usage includes applying stickers to the tuning buttons to prevent users from finding foreign broadcasts.

State-approved radios in North Korea are fixed to prevent tuning to non-official stations, but the authorities have used additional methods in recent times to handle the increasing amount of personal radios in the country. In addition to radio controls, authorities also place heavy restrictions on DVD players, phones, televisions, and other media devices.[…]
