Yet Another Internet Radio!

by Richard Schreiber (KE7KRF)

After deciding that an internet radio could be an important source of entertainment in our household, we formulated a few general guidelines:

  • We opted not to use an aggregator but would pick and choose stations we enjoyed and discover the URL’s ourselves. Also would be satisfied with a couple of dozen stations. Based on a recent decision to pare down the number of TV channels we were paying for, having access to hundreds of stations seemed impractical and unnecessary.
  • The price had to be affordable, thus eliminating many stand-alone, commercially available internet radios.
  • We already owned a quality portable speaker (Bose SoundLink Mini) so the internet radio didn’t need to duplicate that component.
  • Didn’t want to tie up nor be tethered to a laptop, tablet, or netbook. We predicted that would eventually lead to less and less use of the radio.

After some research, coupled with the fact I already had some experience with Raspberry Pi computers, that small device appeared to be our best choice. I had recently purchased the newer 2 B model, which has plenty of computing power, and had installed Ubuntu Linaro as the OS. (As an aside, this OS has not to my knowledge been upgraded for the latest Raspberry Pi 3). There are several other operating systems that will work just as well including the official Raspbian OS available through the Raspberry Pi Foundation.

I installed the MPD music player daemon and its client MPC, which is used to add to and delete station URL’s from the playlist, control volume, etc. An important find was the iPhone app called MPod which provides remote wireless access to the features of MPC. At the moment it is a free app for the iPhone (in my case the iPod Touch).

For portability, my Raspberry Pi is being used “headless”, meaning it is not connected to a monitor, keyboard or mouse. If maintenance is required you can use PuTTY, a SSH and telnet client, wirelessly from a Windows (or MAC?) PC, using a command-line interface. Mainly this is needed to shut down the Raspberry Pi properly before turning off the power, but it boots completely on its own when powered up. The MPod app will then load the playlist of stations and let you start playing the radio without direct access to the Raspberry Pi.

The sound output of my Raspberry Pi is connected to the auxiliary port of our Bose SoundLink Mini Bluetooth speaker. But instead of trying to implement Bluetooth on the Raspberry Pi, I took the easy way out and use a direct connection. The sound reproduction from this setup is very good, though audiophiles might be somewhat more critical.

The above represents a minimal investment if you already have a good speaker on hand. It does require some on-line research and learning at least enough to install the OS and software. The good news is that there are many websites and forums providing step-by-step instructions and helpful hobbyists willing to explain some of the more cryptic aspects. A few of the websites that I found to be helpful:

http://www.instructables.com/id/Arduino-Raspberry-Pi-Internet

http://cagewebdev.com/raspberry-pi-playing-internet-radio

https://learn.adafruit.com/raspberry-pi-radio-player-with-touchscreen

A couple of these also explain how to add a display to your Raspberry Pi internet radio.

Our Raspberry Pi radio is on each evening and has been trouble free. It is worth mentioning that this is a very portable setup, and can even be powered by a battery pack (the kind used for recharging tablets and cell phones) for a few hours. Of course you need to be near a wifi hotspot.


Thank you, Richard! What a great way to use the inexpensive Raspberry Pi. I have a spare Pi2 and an amplified speaker here at the house. Though I don’t need another WiFi radio, it would be fun putting this little system together. 

Muzen Audio handcrafted radios

Many thanks to SWLing Post contributor, John Figliozzi, who writes:

This [company] was mentioned in regard to the CES show out in Las Vegas:

http://www.airsmartaudio.com/

It’s a Chinese company with a rather novel approach to the design of modern radios — AM/FM/Internet Bluetooth, along with the use of tube amplifiers in some models. The web site is almost all in Chinese but the pictures are cool.

Air Smart Audio is the parent company; Muzen Audio the subsidiary.

John also shared the following item from Radio World:

Muzen Audio Group’s founder Dejun Zeng, referred to as the “Father of the Tube Amplifier” in China, is looking forward to the new challenge, saying in a statement: “It is my greatest desire to build a legacy with this organization that will lead customers to say, ‘I am proud to have a Muzen radio.’”

The company received a 2017 CES Innovation Award for their new AM/FM/internet radio and Bluetooth speaker lines, the fifth CES Innovation Award received by Zeng. Muzen Audio also designs a series of vintage-style tube amplifier radios and what the company calls “on-the-road” radios.

(Source: Air Smart Audio)

Thank you, John!

From what I gather, Muzen radios are very much “boutique” radios, thus come with a “boutique” price tag–some models costing as much as $500 US.

Still: it’s refreshing to see a Chinese radio manufacturer marching to their own beat, making handcrafted products in small batches.

According to Twice.com, Muzen recently introduced the  “Classic 1” AM/FM radio with Bluetooth speaker that is powered by a “fluorescent display tube amplifier.” Twice notes:

The Classic 1 is handmade and crafted with real rosewood, and every unit comes with a unique code verifying its hand craftsmanship.

Frequency response of the speaker is 75Hz to 16KHz, of the amplifier, 30Hz to 20KHz.

Pricing and availability will be announced during CES 2017.

I’m looking forward to learning more about Muzen radios! I do love the designs.

Wi-Fi Radio Primer Part 3: Review of the Grace Digital Mondo and Amazon Echo

I originally wrote this three-part WiFi radio primer and review series for the April, May and June issues of The Spectrum Monitor magazine.  Each part of this series will be posted with the tag: WiFi Radio Primer. You can read Part 1 by clicking here and Part 2 by clicking here–I hope you enjoy Part 3 below:


WiFi-Radio-Lineup

We’ve finally arrived at the final part of our three-part primer on WiFi radios. By “WiFi radios,” of course, I mean Internet radio devices that have the sole purpose and dedicated function of streaming radio audio––devices which have now won over this die-hard radio traditionalist, not to mention, his entire family.

In Part 1 of our WiFi Radio Primer we discussed what makes WiFi radios “tick”––their ability to find radio stations via radio station aggregators. We also discussed the comparative merits of the most dominant aggregators on the market, and took a look at one easy alternative to the WiFi radio, namely, streaming from your smartphone or tablet.

In Part 2 we took a quick look at the WiFi radio market and the various manufacturers and models available that use proper aggregators with market longevity. We also reviewed the CC WiFi and Sangean WFR-28 WiFi Radios.

In Part 3, our final part in this series, we’ll investigate the Grace Digital Mondo and the Amazon Echo.

The Grace Digital Mondo

Grace-Digital-Mondo-Front-AngleWhen I mentioned to TSM publisher Ken Rietz (KS4ZR) that I was in the process of reviewing several WiFi radios, he encouraged me to check out the Grace Digital Mondo, which is his personal favorite. Upon unboxing the radio, I could see why Ken likes the Mondo––the unit is stylish, easy to carry, sturdy, and features a rather exceptional color display. It also offers more functions and buttons on the control panel than any other radio I tested (a very handy thing, indeed).

Grace-Digital-Mondo-Front-Panel

The tuning control knob cycles through selections on the display with ease; the buttons all have a tactile response and are backlit. The Mondo even includes thumbsup/down buttons for music service like Pandora.

The Mondo also ships with a small, full-functioning remote control, which fits easily in the hand and is more tactile than the CC WiFi’s mini-remote control. Since I had already established a Reciva aggregator account (for the CC Wifi), getting the Mondo “on the air” was quite simple: I simply registered it as a new device at the Reciva website, restarted the radio, and all of my station memories, folders, and notes were instantly there. Indeed, even if I hadn’t already established a Reciva account, I feel confident that the process of finding stations and organizing them with Reciva would have been easy.

Grace-Digital-Mondo-Front

The Mondo has a built-in speaker that delivers beautiful, rich audio. It’s certainly a notch above the CC Wifi and Sangean WFR-28. The Mondo also has a built-in dual band equalizer with five preset modes, a nice touch. If I have a criticism of the Mondo’s audio, it would be that it caps the volume a little too low. While the radio is loud enough for day-to-day listening, some may find that it can’t reach the levels that may be desired if you want a bit more volume––for example, music for a party. For me, this is not a deal breaker, as its loudest setting still fills the main living area of our home with sound. I imagine the radio designers capped the volume to maintain the excellent overall fidelity of the internal speaker.

Grace-Digital-Mondo-Top2

I love the color display screen, but do wish that it was a touch screen. When using the front panel to navigate the radio, you must cycle through the option with the main tuning knob. It’s fairly painless, to be honest, but I hope their next radio does employ a simple capacitive touch screen; at the $145 price level, I feel like this could be implemented.

The Mondo has a USB port, RCA composite line out, 1/8" stereo Aux In and a DC power connector on the back of the unit.

The Mondo has a USB port, RCA composite line out, 1/8″ stereo Aux In and a DC power connector on the back of the unit.

I also love the fact that that the Grace Digital iOS/Android app serves as a remote control (much like that of the Sangean WFR-28) that can be used anywhere within WiFi range. The app has a lot of user-friendly features and makes searching through stations quite easy. My only complaint about this app is that many of the listings are in a fairly small font, thus touching to select an individual station name or category can be challenging on a small smartphone screen. Changing orientation from vertical to horizontal does not, unfortunately, increase the font size. I hope that a future update will allow for larger print, as my larger fingers have a hard time selecting stations and folders accurately.

Pros:

  • Optional battery (see con)
  • Very simple operation
  • Full, well-balanced audio for both spoken word and music
  • Proper “snooze” button on top of radio, perfect for the bedside listener
  • All functions can be easily navigated via the radio’s front panel (no remote necessary)

Cons:

  • Special battery pack; not standard cells ($40 option)
  • Audio volume can become quite loud, but not very loud
The dedicated volume control and snooze time on top of the Mondo make it an ideal bedside radio choice.

The dedicated volume control and snooze time on top of the Mondo make it an ideal bedside radio choice.

I can see why so many listeners love the Grace Digital Mondo and why it receives positive reviews. If you’re looking for an intuitive, attractive portable WiFi radio–with audio that suits both music and the spoken word–the Grace Digital Mondo may very well be your best bet!

The Grace Digital Mondo can be purchased from the following retailers:

The Amazon Echo

Amazon-Echo

Without a doubt, the oddball in this group of WiFi radios is the Amazon Echo. What is the Echo? Amazon describes it thus:

Amazon Echo is designed around your voice. It’s hands-free and always on. With seven microphones and beam-forming technology, Echo can hear you from across the room—even while music is playing. Echo is also an expertly tuned speaker that can fill any room with immersive sound.

Echo connects to Alexa, a cloud-based voice service, to provide information, answer questions, play music, read the news, check sports scores or the weather, and more—instantly. All you have to do is ask. Echo begins working as soon as it detects the wake word. You can pick Alexa or Amazon as your wake word.

In essence, the Echo is an interactive audio information and entertainment system. What piqued my interest in the Echo was the fact that it is one of the few devices that uses the TuneIn aggregator for Internet radio streaming. C.Crane also makes a TuneIn-based radio––the CC Wifi 2––but I did not review it for this series. Amazon reviews indicated that the Echo did a fine job via TuneIn, so I took a chance and bit the bullet.

Like the other WiFi radios on this page, I’ve been using the Echo daily for nine months now. For most consumers who’ve purchased the Echo, I doubt the option of using Internet radio was the deciding factor in its purchase. Here, we’ll only focus on the WiFi radio aspects of the Echo.

Amazon-Echo-Logo

Once I unboxed the Echo, I was impressed with its sleek, cylindrical design. The tubular chassis feels relatively sturdy. Once placed on a table, even though it stands at about 10 inches tall, the base is wide enough that it doesn’t feel like it’ll tip over. It looks very unlike a radio.

Amazon-Echo-Volume

Volume can be adjusted by turning the light ring on top of the Echo. The audio is robust and room-filling.

What’s immediately obvious that the Echo lacks controls you find on other devices. In fact, there’s only a microphone mute button and the top of the device rotates like a large volume knob. There is a blue lit ring that lights up based on the feedback the Echo gives you (for example, to let you know it’s listening, answering, or “thinking”).

Amazon-Echo-Top

Set up is very simple––it’s complete in a matter of moments. Though virtually every function of the Amazon Echo can be controlled by your voice, you need to download the accompanying app for your smartphone or tablet (both iOS and Android supported). The app acts as a remote control of sorts, but as of the time of posting, falls a little short of my expectations.

So how does it work as an Internet radio? Brilliantly––well, almost.

First of all, the built-in speaker system is absolutely superb. It has the best, room-filling, rich audio fidelity of any other device reviewed here. It sounds much larger than it actually is. Best yet, it’s even a little hard to pinpoint where it is in a room; we’ve had house guests that couldn’t locate it in our living room without assistance. I’ve read reviews from audiophiles that believe the Echo’s audio falls a bit short of Amazon’s claims, but nonetheless, I’m pretty impressed.

Secondly, since the Echo uses voice commands, you never need to look for a remote or even touch the device to start it, change the volume, or tune it. Indeed, there’s no tuning knob: you simply ask the Echo for what you want to hear. For example, I could ask, “Alexa, play WNCW.” The Echo will then start streaming public radio station WNCW. I could also ask, “Alexa, play a radio station.” The Echo replies, in a pre-recorded female voice (think Siri), “What would you like to hear?” I could then say, “jazz” or “rock-and-roll,” and the Echo would select a station from TuneIn. If I ask the Echo to play a radio station that happens to belong to the iHeart radio network, it will default to the iHeart radio stream.

Sounds terrific, right? Well…not exactly.

Alas, the Echo struggles to recognize some station call letters. From the example above, there was no difficulty playing WNCW or WWNC, but when I asked for CFZM (740 AM Toronto), it was confused. You basically need to know how the station is listed in TuneIn or iHeart radio in order to know exactly what to ask for. In the case of CFZM, I looked up the entry and discovered that it’s listed (via TuneIn) as “Zoomer Radio.” I found, though, that the only combination of words I could use to get the Echo to play CFZM was, “Alexa, play radio station Zoomer Radio.” And that was after innumerable trials.

This is where voice commands––which should make this system incredibly accessible––actually make it very frustrating. The night I installed the Echo in my home, I attempted to have it play the the UK 1940s Radio Station, an Internet station I particularly like. After about fifteen minutes of trial and error––attempts to speak more clearly, in different accents or pitches, using different word combinations––I eventually discovered the only way I can get the Echo to play this station is by asking, “Alexa, play a program,” and when it asks which program I would like to hear, I reply, “The 1940s Radio Station.” The prefix “UK” must be eliminated from the phrase, as it is unrecognized.

When muted, the Echo's light ring glows red as a reminder.

When muted, the Echo’s light ring glows red as a reminder.

Don’t get me wrong: I think the Echo’s voice commands are nothing short of amazing. I don’t have to stand next to the device or speak very loudly––I can be across the room and speak in a normal voice; even with ambient noise and music in the background, the Echo almost always “hears” my requests.

A huge mark against the Echo, however, is that the Echo cannot link up to your TuneIn account––at least, not at present. This means the Echo can’t sort through your station memories or use your most recent playlists to help decipher what you’re asking it to play. I sincerely hope that Amazon remedies this flaw in a future software upgrade. The Echo will, however, link to your iHeart Radio, Audible, Pandora, and (of course) Amazon accounts.

There are no memory presets with the Echo: you simply ask for the station you want to hear.

Being an Amazon Prime member with an Echo means that the Echo will stream Prime content like music, and even read Audible books to you, without advertisements or interruptions. I’m not the biggest fan of Prime Music playlists, but I must admit that I’ve been impressed with the 1940s-era music selection (again, one of my favorite genres). I can ask, “Alexa, play Tommy Dorsey,” and the Echo will produce a variety of Tommy Dorsey numbers without any ads or interruptions.

I should note, too, that kids love the Echo because it’s also quite accessible to them (and will spew out almost an endless number of riddles and corny jokes). It “understands” their young voices just as easily as those of the adults in the house.

Pros

  • Very easy setup
  • Excellent audio
  • If you’re a fan of Amazon, or a Prime member, you’ll be pleased with the added functionality
  • Links with Pandora and iHeart Radio accounts (see con)
  • Much more functionality than a typical WiFi Radio
  • Echo functionality is continuously improved–weekly, even daily–with automatic software updates

Cons

  • TuneIn: long radio station names are not always understood. Takes voice training, trial and error, on the part of both device and listener/programmer
  • Advanced music features (Prime Music is a default) requires Prime membership purchase at $99 annually
  • No line out
  • Well centered in the Amazon.com ecosystem
  • No link (yet!) to TuneIn account preferences
  • Relies solely on voice commands for TuneIn Radio, Alexa remote app doesn’t allow station tuning (at time of publication)

There is one uneasy truth about the Echo that is always in the back of my mind, however: it very much lives within the Amazon ecosystem––and thus puts you there, too, like it or not.

Admittedly, if you’re a regular Amazon customer, especially if you’re a Prime member, you may appreciate the functionality and links to Amazon’s own content, along with the requisite personalization and customization. It’s handy to be able to ask Alexa to put an item on your (Amazon) shopping list. But if you like privacy and anonymity, the Echo doesn’t necessarily respect that.

I imagine, like Apple’s “Siri” and Google’s “Google Now,” Amazon is in a position to gather a lot of data about your listening habits, just like it follows your purchasing habits. Amazon states very clearly that the Echo only listens after the wake-up word “Alexa” is spoken, but it just feels a bit odd knowing you have an Internet-connected device that is always on…and always listening to you.

The Amazon Echo is sold exclusively by Amazon.

Summary

Each of the WiFi radios we’ve investigated––the C.Crane CC Wifi, Sangean WFR-28, Grace Digital Mondo and Amazon Echo––have their strengths and weaknesses, and each has some highly unique characteristics.

The CC Wifi

The C.Crane CC Wifi

The C.Crane CC Wifi, for example, has been on the market longer than its competition, thus lacks a color display and any sort of smartphone functionality. Still, at time of publishing, it is the least expensive in our comparison and offers good sound quality and overall functionality for the price.

C.Crane also offers excellent customer support to back this little radio should you encounter problems.

The Sangean WFR-28

The Sangean WFR-28

The Sangean WFR-28, in my book, offers the most “bang-for-buck” of this bunch.

Though its audio fidelity isn’t quite as good as the Grace Mondo and Amazon Echo, it’s still better than I anticipated. The price point is only slightly higher than the CC Wifi, and for that you get a color display with intuitive controls and smartphone application remote functionality.

The Sangean Frontier Silicon aggregator is also very easy to use––perhaps the easiest, in fact, to organize memory folders. With four standard NiMH D cells internally-charged, you can look forward to hours of portable WiFi radio entertainment. Best yet, the WFR-28 is the only WiFi radio we tested that also has a built-in FM receiver.

The Grace Digital Mondo

The Grace Digital Mondo

The Grace Digital Mondo looks and feels much like the beloved Logitech Squeezebox which was discontinued by the manufacturer some time ago.

Like the Squeezebox (and the CC WiFi) it uses the excellent Reciva aggregator.

Audio is well-balanced and offers above-par fidelity, though I do wish it could serve up a little more volume. And it’s quite portable, especially if you splurge for the proprietary battery pack.

The Amazon Echo

The Amazon Echo

The Amazon Echo is quite an amazing device on many fronts––especially if you’re an Amazon Prime member. If you’re not a Prime member, and/or don’t particularly like global media Internet superstores like Amazon, you might pass.

While the Echo has access to both the excellent TuneIn aggregator and iHeart radio, calling up stations with voice commands can be incredibly frustrating.

Here’s the thing, though: the Echo is being aggressively updated by Amazon. New functionality is added weekly and its popularity is clearly growing.

I hope Amazon will eventually allow the Echo to tap into TuneIn preferences so favorite stations can be found quickly and, perhaps, with keywords (think, “Alexa, play 1940s” and it calls up The UK 1940s Radio Station). At present, Alexa only accurately calls up the stations we request 60% of the time, and discovering the right word combination to increase this percentage is monotonous.

So, which radio did we choose?

My wife and I find that we’ve used two models more than others: The Amazon Echo and the Sangean WFR-28.

We find that we use the Echo to listen to only a handful of favorite radio stations via TuneIn. Most of the time, we play only our favorite stations with the Echo, so that we we can simply ask, “Alexa, play TuneIn.” She’ll call up the last station played. With full fidelity and a down-facing speaker system, it’s hard to detect where the Echo’s room-filling sound originates. But what we have found the Echo really good for is hands-free Internet access––besides reminding us of things and offering an impromptu alarm, it’s a a weights and measures converter, a weather forecaster, a headline newsreader, a science-fact researcher. And for our kids? The Echo is a dictionary, an encyclopedia––and, I’m afraid, a joke generator. Thus, the Echo has become a fixture in our home, and in my estimation, is a value at the $179 asking price.

The Sangean WFR-28

The Sangean WFR-28

The Sangean WFR-28, though, is my favorite WiFi Radio in the bunch. Why? It offers such good value, and is so simple to operate. It’s a great little companion around the house and can easily be moved from location to location. Good quality rechargeable D cells will power it for hours upon hours.

But the clincher is this: everyone in our house gave it a thumbs up. Even my wife. That’s good enough for me, and so we’re keeping it…on.

Wi-Fi Radio Primer Part 2: Review of the CC WiFi and Sangean WFR-28

I originally wrote this three-part WiFi radio primer and review series for the April, May and June issues of The Spectrum Monitor magazine.  Each part of this series will be posted with the tag: WiFi Radio Primer. You can read Part 1 by clicking here–I hope you enjoy Part 2 below:


CCWifi-Front-2

As I mentioned last week in the first of this three-part primer on WiFi radios, I never thought a WiFi radio was something I’d ever acquire.  By “WiFi radios,” of course, I mean Internet radio devices that have the sole purpose and dedicated function of streaming radio audio, and so, as a die-hard ham with a penchant for a well-balanced tuning knob, I just couldn’t see the need for what I thought of as an overly-simple, perhaps even redundant, device.

Indeed, until I began the as a search for the perfect radio for my family and XYL (“ex-young lady,” old ham radio speak for wife), I had used only an app on my smartphone (with headphones), and on tablet PCs connected to amplified speakers, in place of a dedicated WiFi radio. And I was fine with that. Or so I thought…

Fast-forward several months. Now that the XYL and kids have been using WiFi radios for a while, I don’t think they’ll go back. And as for myself? Yes, I’ve crossed that no-return boundary, too. Our whole family’s now joined the WiFi radio club, and the truth is, we’re all enjoying the WiFi’s simplicity and unique benefits.

In Part 1 of our WiFi Radio Primer, we discussed what makes WiFi radios tick––their ability to find radio stations via radio station aggregators. We also discussed the comparative merits of the most dominant aggregators on the market, and took a look at one easy alternative to the WiFi radio, namely, streaming from your smartphone or tablet.

Now we’ll investigate some of my picks from the current market.

WiFi radios: an overview

WiFi radios, by and large, look like traditional radios; they typically have backlit digital displays, front panel buttons to recall memories, and an internal speaker. They function like them, too, in that they play radio stations––but there’s where the resemblance stops. Streaming lnternet audio, and their dependence upon an aggregator to do this, sets them entirely apart.

The market for WiFi radios is actually not as broad and diverse as the shortwave radio market. If you’re seeking a quality device that uses a well-known, properly-curated station aggregator (again, see Part 1 for more on this), you’ll be looking at about a dozen (or so) radios currently on the market.

Here’s a short list of the current market’s most popular WiFi radios. Note that this is by no means a comprehensive list––it’s a curated list of WiFi radios that are in wide use, are relatively simple to operate, have built-in speakers, and that use reliable aggregators. I’ve noted the aggregator in parentheses as well as the average US purchase price.

The Pure Evoke F4 (untested)

The Pure Evoke F4 (untested)

Amazon:

CCrane Company:

Grace Digital

Pure

Sangean

And now, let’s meet our real contenders

After much research and head-scratching, I chose four WiFi radios from the above list: the C.Crane CC WiFi, the Sangean WFR-28, the Grace Digital Mondo and the Amazon Echo.

FYI––and in full disclosure––here’s how I obtain my review radios. To keep my review budget within reason, I contact a supplier and request a loaner unit for review that I may return or purchase afterward; otherwise, I purchase the unit(s) outright. In this case, I purchased the Amazon Echo ($179), Grace Digital Mondo ($150), and rechargeable “D” cells for the WFR-28 ($30), while both C.Crane and Sangean kindly opted to send sample review radios, this being a less expensive route for these retailers. When I receive samples, my policy is to give away those I don’t wish to keep; for those I do decide to keep, I donate the full retail price to Ears To Our World, a 501(c)(3) non-profit which sends self-powered shortwave radios to teachers in off-grid developing world communities.

The decision process, this time, was a particularly difficult one. Every model has its advantages and disadvantages; and there are no “perfect” WiFi radios––at least, none that satisfied all of my stringent requirements:

  • Handy size
  • Intuitive display
  • Dedicated memory buttons on front panel
  • Clear, robust audio
  • External connections
  • An internal rechargeable battery option (for portability)
  • Easy setup
  • Remote control
  • Traditional FM and/or AM radio tuner

Several friends urged me consider the Pure EVOKE F4, which reportedly has excellent audio, a simple interface, and superb customer support. Plus, it’s a sleek little device, and…well, frankly, cute. Many have also touted Pure’s own proprietary aggregator, as well. But I just couldn’t justify purchasing and reviewing a WiFi radio with such a hefty price tag ($225), especially knowing that I would also need to purchase the optional battery pack ($50) for a total performance picture.

Reviews

Following are summary reviews of each radio I tested. These are not comprehensive reviews covering every feature; rather, in these summaries, I focus my analysis on their ability to tune stations, on audio quality, on portability, and simply on general usability.

The C.Crane CC WiFi

CCWifi-Front-Angle-2

I’ve had many C.Crane radios in the past. I love C.Crane products because they’re typically well-designed, effective, and because C.Crane offers excellent customer support.

The CC WiFi radio has been on the market longer than any other WiFi radio reviewed here. When I first unboxed the CC WiFi, I was a little surprised by its diminutive size: it is, perhaps, 30% smaller than I expected (based solely on web images and from the catalog). It comes with a small remote control with blister/membrane style buttons. The front panel on the CC WiFi is very simple: one large knob, six buttons, and a monochrome backlit two-line alpha-numeric display.

The front panel of the CC Wifi is simple and intuitive. The main knob acts as both a selection dial and volume control.

The front panel of the CC Wifi is simple and intuitive. The main knob acts as both a selection dial and volume control.

Setup is fairly easy; the accompanying owner’s manual walks you through the process (another C.Crane strength is their production of good-quality manuals). Once I had set up the radio and registered it with the Reciva aggregator, I was tuning in the world.

The CC WiFi’s plastic chassis feels rather thin––at least, thinner than I would have expected. But the radio is surprisingly lightweight, perhaps as a result of this. Fortunately I was pleasantly surprised by the audio from the internal speaker. It provides a full sound and is more than adequate for medium-sized rooms. Bass tones are present, though not especially deep. It’s wonderfully balanced for the spoken word.

All of the external ports are on the rear panel of the CC Wifi and include an ethernet connection, headphone jack, line out jack and power port (7.5 VDC).

All of the external ports are on the rear panel of the CC Wifi and include an ethernet connection, headphone jack, line-out jack and power port (7.5 VDC).

The CC WiFi only has three buttons on the front panel of the radio that act as dedicated memory presets. I wish this number were, at the very least, doubled. With the provided remote control, of course, memory presets are expanded to 99 allocations. Fortunately, you can pretty much operate the CC WiFi’s functions without the remote control (a bonus for those of us who tend to misplace tiny remote controls).

There are a few updates that I think would make the CC WiFi shine:

To help with portability, it would make sense to add a carry handle and capacity for internal rechargeable batteries. The CC WiFi requires a DC power supply to operate; this is a shame because I suspect other listeners, like me, often enjoy radio away from home where there are no main power outlets. The unit is small enough, and lightweight enough, that it would lend itself very well to portability.

CCWifi-Display

Though I’m sure the two-line backlit display was among the best in its class when the CC WiFi was introduced, I now find myself wishing this display could be a bit wider, taller, and (ideally) in color. The display is small enough that if you’re browsing stations with the accompanying remote control, you need to be within a few feet of the radio. If it’s across the room, however, it’s very difficult to navigate.

Additionally, the display width is not sufficient for longer Reciva station names/labels. As an example, I have a folder with local CBC stations from across Canada. Stations are labeled with the town or city name following, for example, “CBC Radio One – Toronto” or “CBC Radio One – Charlottetown.” When I’m browsing the folder of CBC stations, the display merely shows me a long list of “CBC Radio One” stations––which is to say, the truncated display cuts off the city’s name. Of course, I can press the right arrow on the remote to have the station name slowly scroll into view, but this is a cumbersome process when browsing the list. There are, of course, work-arounds for this––I could, for example, create folders for each city, or assign the station to a dedicated memory position––but the then I would have to drill down another level to find my station. “Work” around is the operative term, in either case, .

Pros:

  • Small size
  • Ethernet connection
  • Line-out audio
  • Headphone jack (on back)
  • Included IR remote control
  • Affordable
  • Audio quite good for size of unit (bass, see con)
  • Extras include:
    • Pandora connect
    • Live365 (now defunct)

Cons:

  • No battery-power option
  • Thin, “plasticky” feel to chassis, seems less durable
  • Occasional slow connection time to WiFi
  • Internal speaker generates (comparatively) weak bass
  • No EQ for audio
  • Only three memory buttons on front panel
  • No smartphone/tablet app

Overall, I think the CC WiFi is a good value and is currently one of the least expensive WiFi radios using the excellent Reciva aggregator. The CC WiFi has a surprising number of features for its price class. None of the criticisms above are necessarily deal-breakers, but some strategic upgrades to this radio would keep it competitive for many years to come.

The CC Wifi can be purchased from the following retailers:

The Sangean WFR-28

Sangean-WFR-28-Front

When I first unboxed the Sangean WFR-28, I immediately noticed its design, which bore a striking similarity to other Sangean AM/FM portables like the Sangean PR-D7. The WFR-28 has a glossy hard plastic body that feels robust and durable. The buttons are spaced well across the front panel and have a tactile responsiveness and weight that speaks of quality. There is a dedicated volume rocker button, five memory preset buttons, as well as a dedicated tuning knob and five function buttons.

The WFR-28 also has an easy-to-read square color screen that provides about five lines of text and can display any broadcaster artwork/logos provided. You can access all of the WFR-28’s functions by using the front panel buttons and tuning controls. As with most WiFi radios, doing so is not as enjoyable an experience as with most traditional radios, since you’re using a tuning control to move up or down through selections on a small display.

The Sangean remote control app allows full control of the WFR-28's functions.

The Sangean WFR-28 does not ship with a remote; however, if you have an iOS or Android smartphone or tablet, you can download a free “remote control” app to control your radio.

I find that this is actually more convenient than with a traditional IR remote, because you can control the radio functions from anywhere within your WiFi network. Not to mention, it’s great to be able to turn the volume up from another room in the house!

What I really appreciate is the ability to browse the full Frontier Silicon database from the app-––so much easier than browsing through the radio’s front panel. I do wish there was a way, however, to add stations to memory allocations via the smartphone app (take note of this for a future app update, Sangean!)

The Sangean remote app even allows you to control the various player modes: Internet Radio, USB, AUX in, and the traditional FM tuner.

If you have a USB memory stick with audio content, you can play it through the WFR-28 via this handy, dedicated USB port on the top of the unit.

Speaking of which, yes, the WFR-28 has a very good FM tuner. I can easily receive one of my benchmark distant-FM stations, and even successfully decode the RDS data––both the remote app, and the radio display FM station information. Nice touch, Sangean!

Sangean-WFR-28-Battery-Compartment

The WFR-28 doesn’t ship with a battery pack: rather, it takes traditional D cells in either Alkaline or NiMH form. I purchased a four-pack of high-quality, high-capacity NiMH D cells––they’ll set you back $25-30, but are well worth the investment. The WFR-28 will internally recharge the cells when plugged into an outlet. Once fully charged, you’ll have hours upon hours of playtime. I haven’t measured the total playtime after a full charge, but I imagine it to be in excess of 24 hours.

Sangean-WFR-28-Back

What is the WFR-28 missing? One obvious thing is a carry handle or strap, always useful. Other than that, it really packs a lot for a $122 radio.

Pros:

  • Good audio fidelity from internal speaker
    • Preset EQ settings
    • Customizable EQ
    • Crisp with noticeable bass tones
  • Affordable
  • One-touch preset buttons (see con)
  • iOS/Android app/remote control
  • Accepts and charges standard NiMH D cells
  • Very good FM receiver/displays RDS information
  • Superb playtime from 4 D cells/batteries
  • USB MP3 playback (MP3 and WMA compatible)
  • Stream Spotify music channels and selections

Cons:

  • Only five preset buttons
  • No carry handle
  • If unplugged to go portable, radio shuts down and restarts on battery power, rather than remaining on
  • No battery indicator on display
  • On a few occasions the audio has failed after being woken up from standby (turning the radio off, then on again, is the fix for this)
All of the external ports are on the left side (facing) of the radio. The WFR-28 has an auxiliary in, line out, headphone jack and power port (7.5 VDC).

Overall, I believe the Sangean WFR-28 is an excellent WiFi radio; when combined with rechargeable D cells, you have a portable multi-function audio entertainment system that’s simple to use. I should note that I’ve also been pleased with the Frontier Silicon station aggregator, as well; although more simple than other aggregators, FS just happens to provide all of my favorite stations and networks (do check for your faves before you buy).
