The C. Crane Skywave SSB: A sneak peek!

Tuesday afternoon, I took a number of portable radios to the field: the Tecsun S-8800, Tecsun PL-880, Digitech AR-1780, C. Crane CC Skywave and the new C. Crane CC Skywave SSB.

Last week, I received a pilot run (pre-production) CC Skywave SSB from C. Crane to test and provide feedback. My unit, of course, is still subject to cosmetic changes and engineering tweaks.

Since this is not a final iteration of the product, I won’t comment or review performance other than to say that if you like the original CC Skywave, you should love the new CC Skywave SSB.

C. Crane has kindly given me permission to post a few preview photos.

CC Skywave SSB Photos

First thing you’ll notice is that the CC Skywave SSB is essentially identical to its predecessor in size and shape.

Indeed, the CC Skywave SSB fits the original Skywave’s carry case perfectly. If you’ve purchased a custom protective case–like this one— for the original Skywave, it’ll fit the CC Skywave SSB like a glove.   As you can see above, the front panel design has changed, though. The CC Skywave SSB accommodates four additional function buttons and sports a re-designed speaker grill (similar to the CC Pocket Radio).  Nice touch! C. Crane thought to use that little piece of real estate behind the backstand.

As many of you know, I’m a one-bag-traveler-kind-of-guy who never leaves home without a shortwave radio. On one bag travels, of course, I only carry one full-featured portable. Space is too precious to carry two.

Listening to the 2016 BBC Midwinter Broadcast to Antarctica while traveling in Canada with the CC Skywave.

The original CC Skywave has pretty much been my go-to travel radio since it was released. I’ve taken it everywhere.

I’ve also taken the amazing Sony ICF-SW100 and the full-featured Grundig G6 (which even includes the AIR band) on trips when I wanted access to single sideband mode–something the original CC Skywave lacked. (Note that both of these radios are now discontinued.)

But when traveling in North America or by air, I really appreciate the Skywave’s excellent NOAA weather radio and access to aviation frequencies on the AIR band. Very handy features for the traveler who likes to stay informed.

By adding single sideband mode to an already capable ultra-compact travel radio, C. Crane has created a welcome radio traveling companion indeed.

Shortwave Recordings from Kilimanjaro

by Chris Johnson

Last month, I took a trip of a lifetime to Tanzania Africa to Climb Mount Kilimanjaro: Africa’s highest point and the world’s highest free standing mountain. It is also known as the “Rooftop of Africa” its summit stands at 19,341 feet or 5895 meters.

With this high elevation I figured that I could pick up a multitude of shortwave signals that I would normally not receive at lower altitudes. So I packed my Sony ICF- SW7600G to capture recordings of various signals, some common, others not so common.

Each night I unpacked my radio and extended the reel-wire antenna and scanned the bands. I came across an assortment of stations that I normally do not hear back home in the USA, but some were quite familiar such as the BBC, Radio Romania, and DW which had Africa as their target. In some cases their broadcast was targeted for Asia.

Below is a map of our trek along the Lemosho route and the camps where we stayed are listed with the recordings and the elevation (in meters) of each camp. The higher we climbed, the signals received were sometimes stronger but the surrounding mountains also limited the reception of others. I did find that the bands were congested with signals from stations that spoke Arabic, Swahili and Chinese, not surprising considering my location. For the purpose of this blog I only included the English speaking stations except for a few.

Unfortunately, the critical weight in our day packs was closely monitored and we could carry only the essentials on our climb from Barafu to the summit so I could not record at the summit of Uhuru Peak. Additionally, our time up there was limited to 15 minutes due to the lack of oxygen at that altitude. Below are selected recordings at each of the camps on the Lemosho route. Enjoy.

Trying to chose between the CC Skywave and Tecsun PL-310ET?

CC-Skywave-And-Tecsun-PL-310ET-SideMany thanks to SWLing Post reader, Joe, who recently asked in our comments section:

“The CC Skywave is more than double the price of the Tecsun PL-310ET. The two radios appear to have similar features and performance. Can anyone suggest a reason why one would want to pay the extra charge for a Skywave?”

Thanks for your question, Joe. I’m asked this a lot by SWLing Post readers, so quickly realized I should just turn my response into a proper post.  Here’s my response in a nutshell:

Tecsun PL-310ET

The Tecun PL-310ET

The Tecsun PL-310ET is (and has been for years) one of the best budget shortwave portables out there.

For the price of $40-45 US shipped (via eBay, for example), you really can’t go wrong.  It’s certainly a benchmark among the ultralight DSP portables.

The ($79-89 US) CC Skywave, in my opinion, has a few advantages:

  1. An excellent weather radio receiver (for folks in North America)
  2. The AIR band which is a fun and useful addition if you live near an airport or like travelling by air
  3. I prefer the Skywave over the PL-310ET on the mediumwave band. Its selectivity and AGC, in my opinion, have a distinct edge over the ‘310ET for MW DXing.

Because of these particular advantages, the Skywave has become my travel portable of choice when SSB reception isn’t a priority.

The CC Skywave

The CC Skywave

You might check out my CC Skywave review because I tried to include reception recordings which I felt represented both radios fairly:

https://swling.com/blog/2014/12/review-of-the-c-crane-cc-skywave-portable-radio/

In short, though? If I didn’t care about the AIR band or NOAA weather radio, I’d be quite happy with the PL-310ET. In truth, you really can’t go wrong either choice.

I can say that I now take my CC Skywave on travels more than my PL-310ET.

Tecsun PL-380: Murray’s new travel radio

Tecsun PL-380 in the Morocco desert.

SWLing Post reader, Murray, recently took the Tecsun PL-380 with him on a trip to view the solar eclipse and then to Morocco for an extended excursion. He writes:

We flew out of Billund Denmark for the [solar] eclipse flight. A couple of days after the eclipse we flew to Cassablanca Morocco, where we were to join our 2 week excursion.

Here is a shot of the radio [above] at our camp in the dunes south of Erfoud in south central Morocco. In total we spent 2 1/2 weeks in Morocco and the desert was the nicest Radio quiet location I have been in. No interference what so ever! And lots of stations. It was great. The battery consumption of the PL-380 was very good. Nice unit.

Many thanks for sharing your thoughts on the PL-380, Murray! It must have been bliss listening to the shortwaves in such an RFI-free area.

Like you, I think the PL-380 is a brilliant travel radio and one I often recommend (click here for my travel radio review). I also travel with the Tecsun PL-310ET and the new CCrane CC Skywave--all great compact portables.

Review of the C. Crane CC Skywave portable radio

CC-Skywave-1While electronics manufacturer C. Crane offers a number of unique AM/FM radios, including some of the best portable medium wave receivers on the market, they’ve traditionally only had two models of shortwave radio––namely, the CCRadio-SW, and the CCRadio-SWP. Earlier this year, however, C.Crane announced a new portable that would join their product line: the CC Skywave.

Admittedly, I was eager to give this little radio a go: C. Crane touts the Skywave as an exceptional travel radio, for which I’m always on the hunt.  Last week, I had my opportunity when C. Crane sent me the new CC Skywave sample for review.  I instantly got to work scrutinizing their newest offering…and here’s what I’ve discovered.

First impressions

CC-Skywave-FrontThe form factor of the Skywave is very similar to C.Crane’s CCRadio-SWP pocket radio; in fact, its smooth plastic body even feels the same. While this radio doesn’t have the rubberized coating that have become popular on radio exteriors in recent years, supposedly to provide an easy-to-grip surface, I’m pleased that C.Crane does not use this, as these coatings can eventually deteriorate over time and with heat exposure, becoming somewhat tacky or sticky to the touch.

CC-Skywave-DisplayThe Skywave’s backlit LCD display is small, but readily viewable from several angles.  All of the buttons on the front of the Skywave have a tactile response, again, similar to the CCRadio-SWP. The buttons require slightly more pressure to activate than Tecsun and Degen models; I prefer this, especially for a travel radio: should I forget to activate the key lock, it’s much less likely that the radio will accidentally turn on during transit.

As always, I attempted first to see how many radio features and functions I could uncover without first consulting the owner’s manual.  In the past, C.Crane products have been some of the most intuitive on the market.  Fortunately, the Skywave did not disappoint: first, I was able to set both the clock and alarm within moments; both essential in a travel radio.

Once the radio is on, it will display either the time or frequency on the main display. While the Skywave defaults to a time display, I discovered that the lock button toggles the display between time and frequency for ten seconds. (Note: After reading through the manual later, I learned that you can actually change the default display mode to either time or frequency–very nice touch!)

CC-Skywave-Keypad

I then turned on the radio and found the memory allocation to be very straightforward: tune to the desired station, then press and hold a number button two seconds to save. Press a button quickly to recall. Memory remembers bandwidth, stereo, or mono (if FM), and any voice or music audio filters utilized–very handy!

Speaking of bandwidth, the Skywave has five on shortwave, medium wave, and air bands: 6, 4, 3, 2, and 1 kHz. By pressing the bandwidth button, you can cycle through these from widest to narrowest. The bandwidth defaults to 3 kHz, but the default can be changed by holding down the bandwidth button for five seconds (with radio powered off).

To enter a frequency in AM/FM/SW, you simply press the FREQ button, then key in frequency. To scan through the band, simply press and hold one of the up/down arrow buttons. Worth noting: the Skywave’s scan function is one of the fastest I’ve seen in a portable.

On the topic of scanning, and since this is a travel radio, I would have liked C.Crane to include an ETM function like that found in the Tecsun PL-310ET and PL-380. It’s quite a handy function for auto-populating temporary memories from a simple band scan. I assume this is not an option on the DSP chip powering the Skywave.

Owner’s manual

Once I had my fun trying to discover as many functions on the Skywave without the manual’s aid, I finally opened it and discovered a few more functions.

One feature I’ve already come to love in the Skywave: the ability to change the tuning speed, and thus frequency step-spacing on the tuning knob (option of 5 or 1 kHz steps), just by pressing the knob itself. I much prefer this to using a front-panel tuning step button because it’s so easy to operate in low-light settings (lounging in bed, for example).

CC-Skywave-Tuning-KnobAnother unique feature of the Skywave is a switchable audio filter for voice or music. With the filter set to “voice,” the audio is enhanced for human voice intelligibility. When set to “music,” it widens the audio filter, thus optimizing audio fidelity. Toggling the audio filter settings between voice and music is very easy, but not intuitive; indeed, it’s almost a hidden feature you can discover via the owner’s manual. Simply press the “1” and “2” simultaneously while listening to a broadcast to toggle the filter.

I should note that the C.Crane owner’s manual is one of the most straightforward and simple I’ve seen in ages. You can tell that, at least in the English version that came with mine, this manual was written by a native English speaker. It made for simple, clear instruction without head-scratching over obscure terms. Even the least technically-inclined user will understand these instructions, no problem.

AM – Medium Wave

After asking SWLing Post readers what they would like me to include in this review, a number of you responded that you wanted me to give the AM broadcast band reception a proper review.

Zoomer_RadioMy foray into medium wave listening with the Skywave started off on the right foot.  The very first night with the Skywave, I tuned it to 740 kHz, my favorite, albeit challenging to reach, AM station here in the North America–CFZM “Zoomer Radio”  While those living in the midwestern and northeastern US can receive Zoomer radio easily enough at night, it is often a tough catch here in the southeast in the evening hours. After nightfall it competes with clear channel stations that also occupy 740 kHz. With a portable radio, the lock on Zoomer is never terribly strong and is very prone to fading.

But after tuning the Skywave to Zoomer, I received CFZM so well it sounded like a local station–in fact, I couldn’t believe it until a station ID confirmed that I was receiving it. Even more surprising was that I received it away from home, in an area plagued with RFI noise where I typically have to carefully turn a radio to null out the noise in an effort to enhance the desired broadcast. But the Skywave somehow mitigated this noise better than my other portables. Even when I turned the radio in the direction of the offending electrical noise, it wasn’t as bad as on other portables.  Truly, the reception was remarkable.

With Zoomer firmly locked in, I hopped into bed, turned the volume to a comfortable level, and listened for at least half an hour before falling asleep. I was pleasantly surprised the following morning, some eight hours later, when I woke to the Skywave playing CFZM at the same level. Phenomenal! Perhaps conditions were exceptionally favorable that night; nonetheless, the Skywave couldn’t have impressed me more.

A side note–on the previous day, I’d inserted two generic alkaline AA batteries in the Skywave; after a total of ten hours playing at medium volume, the battery indicator still showed full capacity.

CC-Skywave-RightMedium wave audio samples

While time won’t allow a full audio sampling of the medium wave band for comparison, I did record the following comparison between the Skywave and the Tecsun PL-310ET (which I regard as one of the more capable sub-$100 ultra-compact portables on the market).CC-Skywave-And-Tecsun-PL-310ET

Since SWLing Post readers specifically asked to hear how the Skywave handles choppy nighttime medium wave DX conditions, I tuned to two frequencies with overlapping broadcasts, one of which was slightly dominant: 950 kHz and 990 kHz. I set the AM bandwidth to 3 kHz on both radios and made the recordings within one minute of each other. The CC Skywave’s audio filter was set to “voice.”

In the following recordings, listen for Radio Reloj  (Cuba)–it’s buried deep in the noise. You might detect the ticking and “R” “R” in Morse code. These recordings were taken within one minute of each other.

The Tecsun PL-310ET on 950 kHz:

The CC Skywave on 950 kHz:

Note that the Skywave pulled out the dominant broadcaster–one I could barely hear on the PL-310ET.

I then made a recording on 990 kHz AM which had a stronger dominant station.

The Tecsun PL-310ET on 990 kHz:

The CC Skywave on 990 kHz:

To my ear, the Skywave was clearer and the commentator’s voice seemed to pop out of the noise better.

I’ve spent a great deal of time listening to the Skywave on the medium wave band this week and I feel comfortable recommending it for the medium wave DXer.

FM

While I’ve spent comparatively less time (thus far) evaluating the Skywave’s FM band, I can say that the Skywave receives my “benchmark” FM stations with ease. Sensitivity also seems to be on par with my other DSP based portables (meaning, excellent sensitivity).CC-Skywave-Left

Shortwave

Of course, being a shortwave enthusiast, I’ve spent the bulk of my listening time since receiving the Skywave on the shortwave bands. And during this time, alas, shortwave radio band conditions have been challenging for any radio. Yet I’m happy to note that this little radio does not disappoint: it has excellent sensitivity and selectivity for a radio of its size. When I compared the Skywave with the Tecsun PL-310ET, in almost every situation, they are nearly equal in performance.

Shortwave audio samples

Below I’ve included audio samples of the Skywave on 9580 kHz (Radio Australia). Under normal conditions, Radio Australia would be a blowtorch signal here in North America, but this particular morning, propagation was quite poor. In the audio, you’ll hear both radios attempting to cope with pronounced fading, with their AGC circuits reacting to the quick rise and fall of signal strength. Both radios were set to a 3kHz bandwidth and the Skywave’s audio filter set to “voice” to help mitigate noise.

CC-Skywave-And-Tecsun-PL-310ET-Side

Tecsun PL-310ET on 9580 kHz:

CC Skywave on 9580 kHz:

Note that Radio Australia was broadcasting music, which can be more difficult to evaluate, but the vocals were prominent enough I felt it made for a good comparison.

This morning, I also recorded WWV on 15 MHz. Again, propagation conditions were poor across the bands, so even WWV (normally very stable) was affected by quick fading (QSB). For kicks, I decided to add the benchmark Tecsun PL-660 to this comparison. If you recall, it received some of the highest marks for sensitivity in our weak signal shoot out. The Tecsun PL-310ET and CC Skywave were set to 3 kHz bandwidth and the Tecsun PL-660 to it’s narrow bandwidth (which I felt was most equivalent).

CC-Skywave-PL310ET-PL660

Tecsun PL-310ET on 15 MHz:

Tecsun PL-660 on 15 MHz:

CC Skywave on 15 MHz:

The good news is that the Skywave is certainly a sensitive and selective portable. While evaluating shortwave performance over the past week, I’ve been pleasantly surprised by how well this little radio receives.

NOAA Weather radio

NOAA-Weather-RadioThose of us living or traveling in North America will appreciate the Skywave’s built-in NOAA weather radio functionality.  Since I have at least a dozen self-powered radios and desktops that have built-in NOAA weather reception, I typically don’t give the band much thought. I figured NOAA reception would be a mediocre add-on with the Skyview. I was wrong.

Not only does the Skywave have NOAA weather radio, but it also has SAME weather alerts. What’s so great about that? Imagine that you’re travelling to a rural area and weather is looking ominous; in this case, you can simply set the Skywave to the strongest NOAA channel and activate the weather alert (choose options for 4, 8, or 16 hours). If severe weather is reported for your geographic area, the Skywave will alert you.

I’m very pleased with the NOAA weather radio reception, as well.  The Skywave receives NOAA stations even better than one of my dedicated weather radios.

AIR band

AirTrafficControllerC.Crane included the Air band for travelers, as a means to listen to air traffic control while in an airport or awaiting a flight’s arrival. I have several portables with the AIR band, but most lack an autoscan ability (Grundig G3, G6), and performance on these tends to be mediocre at best.

I’ve traveled to three different cities over the past week and used the Skywave to tune to the local air-traffic control tower. After a bit of scanning, it eventually found the frequency, and reception was quite good. I have not yet used the AIR band in an airport (notorious for RFI) nor in a large metro area, so I can’t comment about performance under those conditions.

What really separates the Skywave apart from my other shortwave portable with the AIR band is that it actually has an adjustable squelch mode. Nice touch!

CC Buds Earphones

HDP-AUDIO-CC-EAR-BUDSUnlike Tecsun portables which typically ship with batteries, an external antenna wire, chargers, travel cases, and the like, the CC Skywave comes with very few included accessories––just a carry case, an owner’s manual, and earphones.

Most of the headphones/earphones that accompany a shortwave radio package are of the cheapest quality. I’m happy to note that the Skywave’s included earphones are the best I’ve ever received as an included accessory with a shortwave radio.

The CC Buds Earphones are in-ear style (which I prefer, for sound isolation) with soft silicone earpieces. They are tuned to a frequency response which favors voice, an enhanced mid-range. For SWLing and MW DXing, I believe they’re nearly ideal. Indeed, I’m planning to use these with my Elecraft KX3 next time I’m operating QRP––I’m sure that SSB will sound great.

Since these are tuned for the spoken word, however, I wouldn’t necessarily favor the CC Buds Earphones over my Sony in-ear buds for music listening.

CC-Skywave-Top

Summary

Every radio has pros and cons, and I jot down my reactions as I evaluate a new radio so as not to forget any details. The following is my list:

Pros:

  • Overall great sensitivity and selectivity for a portable in this price class
  • Considerate design, well-tailored for the traveler:
    • Compact size
    • Air band
    • NOAA weather radio
    • Easy to set clock and alarm
    • Simple controls
    • Lightweight
    • Operates on 2 AA batteries
    • Charges from Mini USB (see con)
  • Wide HF frequency range (2.3 up to 26.1 MHz) compared to the PL-380/PL-310 (2.3 up to 21.95 MHz)
  • AIR band is truly functional: includes both scanning and squelch
  • NOAA Weather radio reception excellent
  • Includes soft silicone earphones (in-ear type) actually worthy of AM/SW listening
  • Auto scanning with the up/down buttons is very rapid
  • Integrated charging circuit
  • Uses common micro USB port for power/charging
  • Tuning speed easily changed by pressing tuning knob
  • Volume control is fully variable (free wheel, analog style), not in pre-determined digital steps
  • Selectable audio filters for music and voice

Cons:

  • Internal speaker audio is somewhat tinny (use of the voice audio filter helps)
  • No external antenna jack
  • No SSB mode (in this price class of $90 US, SSB is an included mode on some models)
  • Only one clock; no provision for dual local/UTC time
  • Mutes between frequency changes
  • Whip antenna is short––only 16” fully extended. While the Skywave seems to perform brilliantly with this short antenna (see pro), I can’t help but wonder if more length might boost some bands.
  • While no inconvenience to me, the Skywave does not come with an adaptor or USB cord for powering/charging. (Should you need it, C.Crane sells a proper noise-free regulated power supply separately ($15 US); however, most buyers will already have these cords and any USB port on your PC or USB-based phone charger will suffice. Also note that listening to virtually any radio while charging will inject noise into the receiver, resulting in sub-par reception.)
  • Can overload on shortwave and AIR bands if located near a strong radio station (see this comment)

Conclusion

The CC Skywave is nearly identical in size to the late and great Grundig G6.

The CC Skywave is nearly identical in size to the late and great Grundig G6.

C. Crane has few shortwave radios in their product line, and all perform rather well for their price point; I know, as I have owned all of them and even purchased as gifts in the past.

But I was concerned a few months ago when I noted the similarity between the CC Skywave and the poorly-reviewed Digitech AR1733, sold in Australia/New Zealand by Jaycar.

Fortunately, it’s clear that C. Crane noticed the shortcomings of the AR1733 and has modified the Skywave’s design and firmware accordingly, which may account for the delayed roll-out of the CC Skywave. Obviously, the Skywave’s ACG circuit has been tweaked to cope with medium wave and shortwave listening, since a poor ACG circuit is one of the shortcomings of the AR1733. But, if so, wow…what a tweak.

Because all in all, the CC Skywave is a excellent little radio. Indeed, in terms of the ultra-compact portable market (models like I included in a recent shoot-out), I think it’s one of the best surprise performers I’ve seen in the past couple of years.

CC-Skywave-1After just one week with it, I’ve already decided to take the CC Skywave along on my travels to see how it performs over time. It will replace my PL-310ET and PL-380 for my one bag domestic and international travelling. The CC Skywave is also especially well-suited for the “go”-bags and “bug-out” bags used in evacuations and other emergencies. Indeed, with AM/FM/SW/AIR plus functional NOAA radio, this little radio packs a lot––in short, the Skywave packs enough to get packed in my bag.

The CC Skywave can be purchased directly from C. Crane. It is also available at (soon) Universal Radio and Amazon.com.
