A review of the Como Audio Solo

como-audio-solo-table

Regular SWLing Post readers might remember that this past summer, I made an impulse purchase–and in doing so, backed a Kickstarter campaign for the new Como Audio Solo.

But exactly why did I buy this small, self-contained digital music device–? Having just completed an in-depth review of several WiFi radios, I certainly didn’t need another.  But the good-looking Solo, with its clean design and walnut casing really caught my attention…I couldn’t resist checking it out.  Plus, in backing the radio via Kickstarter, I was able to purchase it for $100 less than the predicted future retail of $299 US.

The Kickstarter campaign funding Como Audio was prompt in communicating updates with backers and providing even more product options during the wait for production and delivery. Although several other snazzy finishes for the Solo were brandished before me, I stuck firmly by the walnut veneer I’d originally chosen.

Fast forward to the present. I finally received my Como Audio Solo a few weeks ago, and have had time to play with it. While I haven’t had time to explore every nuance of this radio, of course, I have had an opportunity to form some opinions.

Design

I don’t often comment on the design of radios I review, but in this case it’s worth noting.

The Como Audio Solo, in wood, is elegant and simple. Love it:

img_20161003_163200127

The only element of the design I’m not typically keen on?  I’m not the biggest fan of devices that sport colored backlit displays; to me they appear a bit flash and faddish, undermining a radio’s overall aesthetic.

But I must say, the Solo pulls it off.  The color display in this case is somehow not too distracting–it’s soft yet crisp, and easy to read even at a distance.

In short, the Solo is a stunning piece of kit, especially with that warm walnut casing, and looks right at home in any setting–office, living area, kitchen, or at the bedside.

I’ve only one gripe with the Solo’s ergonomics: the front control knobs are a little too close to the bottom of the recessed controls area. When I try to turn a knob–for example, attempt to tune the FM band–I find my fingertips won’t fit between the knob and lower edge of the recessed panel, making the knobs a little hard to turn in one fluid motion. (Of course,this is also due to the fact that I have big fingers; my wife doesn’t seem to have this problem).

But this isn’t a dealbreaker as I’m finding I don’t often need to reach for the front controls, anyway.  Why? Because the rig’s IR remote–or better yet, its smartphone app–control the radio effectively at any convenient distance from the radio.  Sweet.

Audio

como-audio-solo-speaker

I’m a sucker for quality audio fidelity, and I must admit that this was one of the biggest deciding factors in purchasing the Solo: it touted extraordinary audio in a modest package, being designed around an acoustic chamber/chassis containing a 3″ woofer and 3/4″ dome tweeter fueled by a 2 X 30 watt RMS amplifier. I was very curious whether it could live up to its initial claim.

After turning on the Solo for the first time, I immediately wanted to hear audio, so I put it in Bluetooth mode and played a few songs, ranging from Jazz to Electronica.

In a nutshell:  Wow.

The audio is strikingly reminiscent of my Tivoli Audio Model One…which is to say, it’s excellent. It packs more audio punch than any of the radios I reviewed in my WiFi radio comparison.

Out of the box, the audio is fairly well-balanced, too. But you can tweak the equalizer, and I did, drawing in a little more bass and treble.  My wife (also a bit of an audiophile) was impressed. And yes, the sound is all the more remarkable considering the radio’s relatively small form-factor:  little box, big voice.

FM Reception

como-audio-solo

The Como Audio Solo is one of the few Wifi radios on the market that has a built-in analog FM and DAB receiver (save the $120 Sangean WFR-28, which has analog FM reviewed here).

Since I live in the US, I can’t comment on DAB reception.  I have, however, had an opportunity to test the FM analog reception.  Keep in mind, I live in a rural area and require a decent FM receiver with telescopic antenna fully extended just to listen to my favorite regional programming.

When I tune the Solo to my benchmark FM stations, it can receive them–but not as effectively as many of my other radios, including the WFR-28. Even when forced to use the Mono setting only, the stations it receives carry too much static for good listening.  So obviously the Solo isn’t as sensitive as some of my other radios, at least in this setting. Indeed, few stations it receives in this area are able to lock in to the point that there’s no static in the received audio. For out-of-towners, this is a bit of a disappointment.

With this said, I imagine if you live in an urban area, the FM receiver should more than please you. I’ve no doubt it can faithfully reproduce beautiful audio from local FM outlets.

I should add that, while FM reception isn’t stellar for distant stations, the RDS information does convey even when the audio isn’t full fidelity.

WiFi radio

comoaudiosolo-internetradio

Of course, the main reason I purchased the Como Audio Solo was to use and review it as a WiFi radio…nothing at all to do with that sharp walnut chassis, or audio power.

As I outlined in my WiFi Radio primer, WiFi radios rely on station aggregators–extensive curated databases of radio stations–to surf and serve up the tens of thousands of streaming stations around the globe.

Based on feedback from Como Audio shortly after the Kickstarter launch, I was under the impression that the station aggregator of choice was vTuner. This concerned me, as vTuner’s reputation as an aggregator is somewhat maligned due to a series of documented faults and weaknesses.  Fortunately, this turned out not to be the case: after the initial confusion, I soon discovered Como had adopted the more robust Frontier Silicon aggregator, instead–a better choice.

Since I’m a pretty big fan of Frontier Silicon and since I’ve already been using their service with my Sangean WFR-28, once I connected my radio to my user account, the WiFi portion of the radio felt identical to that of my WFR-28. Simply brilliant, as the Frontier Silicon radio portal gives the user flexibility to create station lists and folders with ease–all of which readily convey to the radio itself.

The Solo also features six dedicated memory buttons on the front panel for quick access to favorites.

Turns out, there’s also a comprehensive manual available online for download (click here).

Summary

And am I please with the Solo so far?

I’ll reply with a resounding “Yes!”

I love the Solo’s design–this certainly is a handsome product. Moreover, I love the audio, and am pleased that it delivers the fidelity promised by its Kickstarter campaign. The Solo and Duet are loaded with features, connections, Aux In and Aux Out audio and digital ports–more, in fact, than any similar device with which I’m familiar. I regret that the rig’s FM isn’t suited for country life, but the audio coupled with its stylish exterior do make up for this somewhat.

I do wish the Solo had an internal rechargeable battery option. Being able to move the receiver to different locations within a home or building could be a major plus for rural FM reception. As my friend John pointed out, however, the audio amplifier is robust enough, it might have been a challenge to implement an affordable-but-effective internal battery without compromising the audio amplifier’s needs.

In truth, I favor audio fidelity over portability for a tabletop radio.

 

In conclusion…do I have any backer’s remorse?  Absolutely not–!

In short, the Como Audio Solo is a keeper.  I’m still marvelling at this classy and dynamic radio that fills our home with rich beautiful audio. A few weeks in, the Solo has already become a permanent feature in our abode. It’s one of the few radios I have that meets my artist wife’s approval in terms of both design and audio.comoaudiosolo-fm

Great job, Como Audio!  If the Solo is any indication of radios to come, I’ll certainly be looking for your future innovations.

Rare Hitachi KW-WSI WorldSpace Receiver on Ebay

This is the first and only “WorldSpace” satellite receiver I’ve seen on Ebay, currently offered at a $175 Buy-It-Now price from a seller in Australia:

http://www.ebay.com/itm/HITACHI-KW-WSI-DIGITAL-RECEIVER-WS-FM-MW-SW1-SW2-/282192383263

The radio is listed as in excellent condition with the original box and literature. Besides the long-gone WorldSpace satellite frequencies, the radio covers medium wave, FM, and most of the shortwave range. A brief PDF data sheet for the radio gives a description of features and operations.

hitachi-kw-wsi

Wikipedia describes this radio’s satellite service as 1worldspace, formerly known as ‘WorldSpace’, is a defunct satellite radio network that in its heyday provided service to over 170,000 subscribers in eastern and southern Africa, the Middle East, and much of Asia with 96% coming from India. It was profitable in India, with 450,000 subscribers.

I wonder if the Hitachi KW-WSI is a reasonable performer for shortwave listening? Does anyone know any technical details of this receiver?

Arvin Model 68R05: John’s 1967 transistor radio

arvin_68R05

Many thanks to John Harper (AE5X) who shares the following in reply to our post about transistor radios:

Attached is a pic of a like-new transistor radio from 1967 [see above].

Remember the days when they bragged about how many transistors a gadget contained?! Sort of like bragging about RAM or clock speed today I guess.

That’s a cute little Arvin radio, John!

You’re right, too–radio manufacturers used to boast transistor compliment like nothing else. Crosley, Zenith and RCA did the same thing–boasting tube/valve numbers–in their 1930s consoles as well. Thanks for sharing the photo of your pocket radio!

Memories and transistor radios

Magnovox 1R 1203I’ve always had an affinity for pocket transistor radios.

The Realistic Model 23-464.

The Realistic Model 23-464.

My first one was an AM-only model: a Realistic Model 23-464. It was about the only new pocket radio I could afford–and purchase locally–when I was a kid.

It was surprisingly sensitive on the AM broadcast band, but the dial was a far cry from accurate. At some point, I either gave this radio to someone or lost it. Last year, I happened upon one on eBay and purchased it for $9 shipped. Its plastic body shows signs of wear, but it works and reminds me of my childhood.

My grandpa's Magnovox 1R 1203

Another pocket AM/FM radio that brings back a flood of memories is the Magnovox 1R 1203. It belonged to my dear grandpa, who also shared and conveyed a love of radio. When I was a kid, we would sit around on his front porch on hot summer days and listen to local AM stations on this little radio, cicadas whirring in the background.

I still have his Magnavox–it sits here in my radio room and brings back memories every time I look at or listen to it.

Am I a nostalgic fellow? You bet!

Anyone else have memories associated with pocket radios? Please feel free to comment and share!

The “Hidden Den” of Pirate Radio

NYC-NewYork-Brooklyn-Map

Many thanks to SWLing Post contributor, Martin Kraft, who writes:

Where’s the hidden den of pirate radio? The Caribbean? The South China Sea? Nope, according to RadioWorld, it’s the New York City metro area:
http://www.radioworld.com/article/nybsa-76-pirates-stations-in-new-york-northern-nj/279213

NYSBA: 76 Pirate Stations in New York, Northern N.J.

A number of pirate stations are operating throughout New York City and Northern New Jersey, according to a recent engineering survey that was recently unveiled by the New York State Broadcasters Association.

According to the survey, 76 stations are currently operating without an FCC license in four primary locations. There are 19 unauthorized stations in the Bronx, N.Y.; 29 in Brooklyn, N.Y.; 13 in Newark, N.J.; and 15 in Paterson, N.J. Brooklyn saw a 58% increase in the number of pirate stations compared to a similar survey conducted in 2015.

The survey does observe that it has likely underestimated the number of pirate stations in the area, and that the total number could be more than 100.

“Like our previous studies, the new survey provides compelling evidence that the FCC needs to address this problem,” said David Donovan, president of the NYSBA. “Last summer, the entire New York Congressional delegation asked the FCC to fix the problem. While the FCC has published an Enforcement Advisory, it needs to devote the manpower and resources to increase its enforcement efforts. Moreover, Congressional action will be important to assist the FCC in these efforts.”

The potential harms associated with pirate stations include: interference to Broadcast Emergency Alert Services; interference to FAA frequencies; and failure to comply with RF radiation rules of licensed broadcast stations.

The survey was conducted by engineering firm Meintel, Sgrignoli and Wallace. The full study can be found here.

Thank you, Martin!

When I visit my buddy David Goren in Brooklyn, I’m simply amazed at the diversity of the pirate radio scene on the FM band. When David isn’t surfing the shortwaves, he’s logging local pirate radio stations. Check out his Facebook page: Flatbush Pirate Decoder. David most recently presented a program on the NYC pirate scene at the 11th HOPE conference–you can download a recording of the presentation here.

Battery Endurance Contest Results: Sangean DT-160CL vs Sony SRF-39FP

Sangean_DT-160CL_17

On August 4, 2016, the same day I received my new Sangean DT-160CL, I popped a fresh set of CVS Max Alkaline batteries into the DT-160CL as well as into my trusted Sony SRF-39FP. The mission? To see which radio could perform longest on a set of batteries.

I set my stopwatch as I turned on both radios, tuned to the same frequency, set the volume to the same levels…and waited.

And waited.  And waited.  And as I waited, I posted updates.

But at last, the waiting is at an end:  here are the contest’s final results.

Sangean DT-160CL: Impressive Performance

IMG_9137

On August 9, I reported that the Sangean DT-160CL finally threw in the towel, logging an impressive 116 hours 30 minutes of operating time–!

Without a doubt, this is one of the longest run times I’ve ever experienced from an AM/FM radio with digital display.

Interestingly, the day after the DT-160CL shut down, I turned it back on, and it operated for an additional 45 minutes or so, obviously absorbing a little more voltage from rested cells. During that 45 minutes period of time, the audio and overall performance was respectable. No doubt the DT-160 shuts down before audio is terribly compromised.

Sony SRF-39FP: The Endurance King!

Sony-SRF-39FP

Amazingly, the Sony SRF-39FP kept running well beyond 116 hours. Well beyond…

By Wednesday morning–one full week from the time I began the endurance contest–the Sony SRF-39FP finally began showing signs of low-voltage: the audio had a small amount of splatter and sensitivity began to be compromised.

Unlike the Sangean DT-160CL, which clearly has a cut-off voltage, the SRF-39FP kept milking the battery for its last vestiges of power.

I decided that I would call a “time of death” for this AA battery when the Sony struggled to receive local AM stations, as well as transmission from my in-house SStran AM transmitter.

This happened approximately 163 hours and 54 minutes into its marathon run.

IMG_9142 (1)

This stopwatch app tracked the full endurance test. I pressed “stop” when the Sony SRF-39FP finally gave up.

Wow, wow, wow.  I simply had no idea any portable could operate almost one full week on one AA cell–! 

IMG_9145 (1)

In truth, I’m sort of relieved the ’39FP finally gave up the ghost. I was beginning to think the thing was powered by some supernatural force…

When I started this test, I thought the Sony SRF-39FP was rated for about 40-80 hours of run time on a single battery.  I couldn’t remember where I got that number until I recently re-read this article from The New Yorker, which highlighted the 39FP’s role in correctional facilities:

“The SRF-39FP is the gold standard among prison radios in part because it runs on a single AA battery, and offers forty hours of listening time…”

Wait, just forty hours? Perhaps from the cheapest AA battery made…

With an advanced chemistry cell like the Duracell Quantum or Energizer Advanced Lithium series, you’ll clearly get three to four times that performance.

DX mode

And here’s the thing: I’m convinced I could’ve gotten much more time out of the SRF-39FP.

Like similar Sony portables, the SRF-39FP has a “DX/Local” switch. When set to DX, the receiver is made to deliver maximum performance.

If you’re listening to a local station, however, “Local” mode is a better choice. You’ll still be able to receive your target station, yet draw much less from the battery.

I left the Sony SRF-39FP in “DX” mode for the entire battery endurance test. Had it been in “Local” mode, I believe I’d be reporting an even longer run time. How much longer, I don’t know, but you can bet that my curiosity will soon get the best of me…I plan to do a separate endurance test to find out.

Clear choices for battery longevity

Sangean-DT160CL and Sony SRF-39FPNo doubt, our little test has proven that radios marketed to the prison system do offer excellent battery performance.

Now I’m very curious whether the standard Sangean DT-160 will offer the same battery performance as its clear-cased counterpart, the DT-160CL. The only difference in the two appears to be that one offers a clock, while the other doesn’t. I wonder if that would have any significant difference on battery life.

Additionally, the Sony SRF-39FP has shown us that analog receivers can be much more efficient than their digital counterparts. We’ve known this a long time at Ears To Our World, and which is why almost all of the radios we supply to schools in remote, rural locations are analog.

Sadly, analog radios are getting much more difficult to find these days as DSP-based receivers have become more affordable to produce.

The Sangean DT-160 is available at Amazon.com and Universal Radio. The Sangean DT-160CL (the version tested) is available through Amazon.
