Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
Check out this brilliant episode of the Radio Survivor podcast which features our Shortwaveologist friend, David Goren along with John Anderson of Brooklyn College:
There are more unlicensed pirate radio stations in New York City than licensed stations. The borough of Brooklyn is a particular hotspot. Producer and journalist David Goren has been researching and recording these stations so that their ephemeral nature isn’t lost to history. To help preserve this legacy and make it accessible to a wider audience he’s constructing an interactive map of Brooklyn pirates, due to be released later this year.
David joins us on this episode along with Prof. John Anderson of Brooklyn College, who has been tracking and researching unlicensed radio for two decades. We discuss the unique qualities of Brooklyn pirates, and how they fulfill the needs of communities that are underserved by other media, why it’s important to preserve their legacies, and why the expansion of low-power FM failed to provide sufficient opportunities in cities like New York.
Astronomers detect signal from the dawn of the universe, using simple antenna in WA outback
They have picked up a radio signature produced just 180 million years after the Big Bang using a simple antenna in the West Australian outback.
The ground breaking discovery, reported today in the journal Nature, sheds light on a period of time known as the “cosmic dawn”, when radiation from the first stars started to alter the primordial gas soup surrounding them.
[…]The signal they’ve been looking for is a miniscule fraction — between 0.1 and 0.01 per cent — of the radio noise from the sky.
“It’s like trying to hear a whisper from the other side of a roaring football stadium,” Professor Bowman said.
The signal is also within the lower range of FM radio, so finding a place on Earth that is free of human radio interference was essential.
That’s why Professor Bowman and colleagues decided to base their experiment at CSIRO’s Murchison Radio-astronomy Observatory, 300 kilometres north-east of Geraldton.
“Going to Western Australia and working at the Murchison Radio-astronomy Observatory was an absolutely critical first step for us,” he said.
There they built a small table-sized radio spectrometer with a radio receiver attached to two metal panels that act as an antenna. Akin to a set-up from the 60s or 70s, the EDGES instrument is much simpler in design than bigger array telescopes around the world.[…]
Despite the legal challenges, Indigenous communities use radio to ‘keep their language and culture alive’.
Sumpango, Guatemala – Sitting in a courtyard, wearing an indigenous huipil dress, Amanda Chiquito glows as she talks about the challenges and successes of working with the community radio station in Sumpango Sacatepequez, Guatemala.
“There is no media that represents our community,” the 25-year-old says.
“There wasn’t a media outlet that could inform us and keep our culture and language alive,” she tells Al Jazeera.
Chiquito is a reporter and radio host at Ixchel Radio, the only community station in Sumpango Sacatepequez, a small town 42km from Guatemala’s capital.
More than 95 percent of the town’s 50,000 inhabitants are indigenous, living in remote areas, where access to information and technology is limited.[…]
Word spread quickly about the mysterious unmarked black SUV parked at a highway exit just outside the town of Ward on January 24. In the self-sufficient mountain community perched at 9,500 feet, strangers always attract attention. But the strangers in the SUV weren’t just a curiosity; they were enforcement agents with the Federal Communications Commission, and they presented a real threat to a beloved community resource.
Since 1997, Ward had played host to an unlicensed FM radio station called Way High Radio. Colloquially known as “pirate” stations, radio operations such as Way High Radio are expressly forbidden by the FCC, which regulates America’s airwaves. That the station had been able to illegally broadcast from 90.5 FM for so many years was largely thanks to the isolation of the mountain town, roughly an hour-and-a-half drive from the FCC’s enforcement office in Denver.
When DJ Willy (not his real name) heard about the federal agents parked near town, he got a sick feeling in the pit of his stomach. This was a moment he’d been dreading for a long time. But he’d also studied up on FCC enforcement, and knew the agents would want to catch someone actually inside the radio station’s studio, a small trailer located next to Ward’s town hall with an antenna on top and a wooden sign that proclaimed “Office of Human Rights.”[…]
IHeart Prepares for Bankruptcy as Soon as This Weekend
Embattled IHeartMedia Inc. is circulating documents for a bankruptcy filing that could come as soon as this weekend for the biggest U.S. radio broadcaster.
Advisers to some of iHeart’s senior creditors have been shown bankruptcy papers that would be used on the first day of court proceedings, according to people with knowledge of the matter. Despite a year of negotiations on a restructuring plan, a formal support agreement still isn’t in place with the most-senior lenders, and the creditors aren’t in restricted talks with the company, said the people, who asked not to be identified discussing private negotiations. Creditors typically agree to restrict some of their activities in exchange for non-public information when talks heat up.
A bankruptcy filing is all but certain, with iHeart and creditors each swapping proposals in recent weeks for a consensual restructuring. But pressure is mounting on iHeart after it missed a Feb. 1 interest payment, with a 30-day grace period about to run out. On top of that, the broadcaster on Thursday skipped payments on two more sets of bonds. If the company files without a pre-negotiated restructuring plan in place, the bankruptcy could turn into a free-fall, with some of the biggest and most contentious specialists in distressed companies potentially tussling for years over about $20 billion of debt.[…]
A few months ago, the radio manufacturer Tivdio contacted me to see if I would be interested in evaluating their new Tivdio HR-11S self-powered emergency radio. I receive requests like this frequently, and often pass on the opportunity since I generally don’t have the time to evaluate the overwhelming number of inexpensive DSP radios that have hit the market in the past few years.
But this time, I seriously considered it. There were two reasons I was interested in the HR-11S:
I purchased a Tivdio V-117 last year, and have been pretty pleased with it; indeed, I’m overdue a review on this unit. We’ve also posted several positive reviews of the Tivdio V-115.
At our non-profit ETOW, we’re always looking for reliable self-powered radios with shortwave for use in areas of the world where radio remains the primary news source.
Thus this radio is a rather rare breed. Tivdio dispatched the radio very quickly, but my work with the Radio Spectrum Archive and several other reviews already in the pipeline took priority.
I’ve had the HR-11S in service for several months, and have now explored every feature to some degree. What follows is my summary and review notes.
Green and Red radios are different models
First things first: note that I’m reviewing the GreenHR-11S. Tivdio also makes a Red version which is actually a different model number: the HR-11W.
The main difference between these models, as I understand it, is the green HR-11S is a shortwave version, and the red HR-11W is a NOAA weather radio version.
Both are useful; why not combine the two roles in one unit? I’m not surprised this radio can’t include both shortwave and NOAA weather radio. Through Ears To Our World, I’ve worked with self-powered DSP radios for many years, and know that a limitation of the DSP chip is that it can be set to feature either shortwave or weather radio, but not both, simultaneously, if both AM and FM are included.
Form factor
The HR-11S has a built-in solar panel.
The HR-11S adopts the standard “flashlight” form factor found in so many other self-powered radios. I think the flashlight functionality is a useful feature and results in a handy form factor. It’s compact, lightweight, and seems relatively sturdy, so is suitable for camping, travel, and off-grid utility.
Flashlight/Siren switch
A small switch on top toggles between four positions. The first two positions are off/on for the main white LED. Though the flashlight aperture is relatively small, the white LED provides enough luminosity to light your immediate path at night, and certainly more than enough to read by.
The third switch position engages a flashing red LED. The red LED is not terribly bright and I’m not sure how helpful this would be in an emergency situation.
The red LED is rather dim and can only flash.
I would much rather have the red LED maintain a steady beam which would be great for amateur astronomers, campers, or anyone else wishing to preserve their night vision.
The fourth position engages a LOUD siren. More than once when attempting to turn on the flashlight in the dark, I’ve accidentally engaged this pain-inducing feature. The switch is small, thus it’s very easy to engage the siren. In a quiet campground, this might annoy your neighbors––not to mention you, yourself. Of course, in an emergency situation, a loud siren could come in handy. I just wish its switch wasn’t combined with the flashlight switch.
The display HR-11S display is backlit and easy to read.
The HR-11S sports a keypad that allows direct frequency input––a very good thing, considering there is no tuning knob.
To band scan, you must use the #7 and #8 key on the keypad to increase and decrease frequency in predetermined steps. And, yes, the radio mutes between frequency changes.
You can also press and hold the #7 or #8 buttons to engage an auto-tune feature that finds the next strong signal.
The HR-11S’ rechargeable battery pack.
To input a frequency directly, simply press the enter button, key in the frequency, then press the enter button once more to engage that frequency. Very simple.
The volume up/down buttons are #1 and #2 on the keypad.
The keypad is not backlit and the layout for volume control, tuning, mode switching, etc., is a bit confusing; it doesn’t match any other radio I’ve ever used. Of course, with time you’ll master the keypad functions, but the design could be made more user-friendly.
Performance: setting expectations
SWLing Post community members know that I tend to review what I call “enthusiast grade” radios: receivers that perform well enough to attract the attention of DXers and dedicated listeners.
Self-powered radios, with few exceptions, rarely impress me in terms of performance. Indeed, some of the best that have been on the market have been analog units (I’m particularly fond of the Grundig FR200).
The Tivdio HR-11S is no exception––don’t expect to snag elusive DX with this unit. It’s not going to happen.
FM
The HR-11S is a capable FM receiver. Performance is on par with most average FM radios: you’ll easily receive all of your local broadcasters, but distant stations may require holding the unit in your hand, careful positioning, or adding an extra bit of wire to the antenna.
The FM audio is quite good via the HR-11S’s built-in speaker.
AM
The mediumwave, or AM broadcast band, is the HR-11S’ weakest suit. AM is plagued with internally-generated noises–especially in the lower part of the band–thus you’ll only be able to clearly receive local AM broadcasters that rise well above the noise floor. Thus I cannot recommend this radio for AM reception.
Shortwave
Shortwave reception is on par with other DSP self-powered radios I’ve tested. As I write this section of the review, I’m listening to China Radio International on 9,570 kHz in my office without even having the telescopic whip antenna extended. (CRI is a blowtorch station, however).
I find that the HR-11S can receive most strong broadcasters and even weaker stations, though the AGC is not ideal when fading is present.
If you’re seeking a self-powered radio with shortwave, the HR-11S is somewhat useful in this regard and is worth consideration.
Keep in mind, though, that an inexpensive dedicated ultralight shortwave radio like the Tecsun PL-310ET will perform circles around this unit.
Bluetooth
One feature I’ve found incredibly useful is the Bluetooth functionality. With Bluetooth mode engaged, you can connect the HR-11S to pretty much any mobile device and use it as a wireless portable external speaker. Since the speaker has decent audio fidelity for the size, and can be powered by battery, it’s a brilliant feature and will make watching videos on your smartphone, for example, that much better.
One negative? At least in my unit, I can hear some internally-generated noises in Bluetooth mode. This is especially noticeable at lower volume levels.
Recording
In full disclosure, I haven’t tested the recording functionality extensively. Built-in radio recording is an interesting feature, but one I would rarely use in a self-powered radio. I did make a handful of test recordings, however, and like many other DSP radios with a recording function, the HR-11S injects noise in the recordings.
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 my initial impressions and observations. Here’s the Tivdio HR-11S pro/con list, from the first moments I turned it on to the present:
Pros:
Keypad entry
Great audio for size
Replaceable battery (Note: after unboxing unit, you must place battery in battery compartment; it’s packed in the side box)
Siren (see con)
Micro SD card for digital storage
USB can port audio from PC
Bluetooth––use as a portable wireless speaker for mobile devices (see con)
ATS (auto tune) function
Multiple power sources:
850mAh rechargeable lithium battery
hand-crank dynamo generator
Mini solar panel
DC 5V input (standard micro USB)
Backlit informative display
Customer service: Tivdio representatives seem to respond quickly to customer emails and comments on Amazon.com.
Cons:
Tuning is cumbersome (no tuning knob)
Mutes between frequencies
Siren too easy to activate, resulting in accidental activation
AM broadcast band (MW) is plagued with internally-generated noises
Keypad configuration is not intuitive and difficult to memorize for use at night or low light settings
Hand strap is very difficult to insert (hint: use a thin loop of wire to help thread it)
At low volume, noises can be heard in Bluetooth mode
Noises heard in recording function
Conclusion
Running an ATS scan on shortwave.
As I mentioned early in this review, I must set realistic expectations when reviewing self-powered radios. When most consumers consider a self-powered radio, they’re seeking a simple, basic radio that will provide information during times of need: power outages, natural disasters, or while hiking, camping, boating, or simply in an off-grid setting.
Internally-generated noises––especially on the AM band––will disappoint radio enthusiasts. If Tivdio could address this in future iterations of the HR-11S, it would substantially improve this unit.
My overall impression is that the HR-11S is chock-full of features, but none of them are terribly refined. There are even some internally-generated noises in Bluetooth mode, which really surprised me as it seems like an oversight by engineering.
I see the Tivdio HR-11S is a bit of a “Swiss Army Knife” of a self-powered radio. It has more functionality and connectivity than any other self-powered radio I’ve tested to date. Its features will, no doubt, appeal to the average consumer––and a quick look at Amazon reviews seem to support this theory. As a radio enthusiast, however, I would pass on the HR-11S until the internally-generated noises have been addressed.
For those who are interested, Tivdio passed along several coupon codes that SWLing Post readers can use to save money, should they decide to purchase the HR-11S:
The following review first appeared in the January 2018 issue of The Spectrum Monitor magazine.
[IMPORTANT UPDATE (October 21, 2018): I’m pleased to report that C. Crane have addressed issues that I found in the first production run of the CC Skywave SSB. Click here to read the update.]
Those who know me know I’m all about travel, and all the things that make the travel experience enjoyable. I like to pack light, taking only the essentials, and if I’m traveling by air, I can easily fit two weeks of fun into one small carry-on. To me, the idea of lugging a huge suitcase, being subject to lost check-in luggage, and fretting over finding room in an overhead bin to squeeze in a huge bag simply has no appeal. Even though I often opt for the budget ticket, which means loading later, I know I can literally be the last one on board without fear because my travel bag is so compact that, if nothing else, it will fit underneath the seat in front of me.
Yet even though I travel light, I never ever travel without a radio. That’s a given in my bag. Since packable real estate in my carry-on is at a premium, I opt for the most bang-for-buck I can manage in a portable radio.
My radio travel partners
To date, I have a few favorite full-featured travel radios and know quite well both their strengths and weaknesses. Here’s a list with some notable pros and cons:
Pros: A 1990s era marvel of compact technology, it sports SSB mode, sync detection, headphone and audio out jacks, external antenna jack, and long life on two AA batteries. It has excellent sensitivity and selectivity. No muting between frequencies spoils listening pleasure.
Cons: Speaker audio is poor, no FM RDS, no weather radio, no AIR band, the battery cover may be easily broken, ribbon cable can break (in early models) and the clamshell design, while a cool feature, isn’t always practical and makes the unit feel prone to damage. Plus, the SW100 series is no longer manufactured and, due to desirability, typically have a price point well above the competition.
Pros: A compact, ergonomic full-featured radio which sports SSB mode, AIR band, external antenna jack, reasonable audio from internal speaker, very good shortwave and mediumwave performance for the size. No muting between frequencies.
Cons: Rubberized coating becomes sticky as it deteriorates, no weather radio, no audio-out jack, no RDS, and it’s no longer manufactured.
Pros: Very affordable (typically $40-50 shipped), excellent shortwave, mediumwave and FM reception, external antenna jack, average audio fidelity from built-in speaker, internal battery charging, common 5V mini USB plug, reasonably durable.
Cons: No SSB mode, no weather radio, no AIR band, no RDS, no dedicated audio-out jack, limited shortwave coverage compared with other portables 2.3 – 21.95 MHz
Pros: SSB mode, great shortwave, mediumwave, fm reception, vertical form factor great for handheld listening while walking/hiking, external ferrite bar antenna enables excellent AM/mediumwave reception.
Cons: Vertical form factor means it’s prone to fall over if placed on a bedside table, no direct entry keypad for frequencies, tinny audio from built-in speaker, no RDS, no AIR band, detachable external ferrite bar antenna is an extra piece to keep up with while traveling.
Pros: SSB mode, AIR mode, squelch control, FM RDS, dedicated fine-tuning control, external antenna jack, internal speaker provides better audio than other compact travel radios. Excellent sensitivity.
Cons: Slightly larger form factor than other travel radios. Somewhat awkward ergonomics. 7 VDC power port is non-standard. No dedicated audio out jack.
Pros: Overall excellent performance on shortwave, mediumwave, and FM. AIR band, North America weather radio (excellent sensitivity) with alerts, squelch control, common 5 VDC USB mini power port with charging capability, a great value at $89
Cons: No SSB mode, no external antenna jack, no RDS,
What radio I decide to pack really depends on the type of trip I’m taking.
If I really want SSB mode to listen to HF pirates, ham radio, or utility stations, I tend to grab the Sony ICF-SW100, the Grundig G6, or more recently, the Digitech AR-1780 [and now the XHDATA D-808].
If I plan to do extended hiking or walking during my trip, I might grab the CountyComm GP5-SSB.
If I only plan to listen to AM/FM/SW broadcasts, and it’s a short trip––or one during which the radio might receive rough treatment––then I might grab the Tecsun PL-310ET. If I leave the PL-310ET in a hotel or drop it, I’m only out about $40. I’ve even been known to simply give one of these to someone, like a kid for example, who shows a fascination in shortwave radio.
If I plan to do off-air audio recordings during my travels, then the Sony ICF-SW100 because it’s the only radio with a dedicated audio-out port. Plus, it’s a great performer.
If I’m travelling by air, however, I almost always choose the CC Skywave: its unique combination of AM/FM/SW coverage, NOAA weather, and AIR band are simply hard to beat. It’s compact, durable, and gets the job done. Plus, the Skywave seems to operate for ages on a set of AA batteries. C. Crane really knocked it out of the ballpark with the CC Skywave.
But there was one glaring omission on the original CC Skywave: Single-sideband (SSB) mode.
Enter the CC Skywave SSB
Earlier this year, I learned about a new radio in development at C. Crane: the CC Skywave SSB. I saw a Beta unit very early on and a few weeks later, knowing how much I appreciate the original Skywave, C. Crane asked me to help test the new Skywave SSB. I was happy to do my bit.
I actually do quite a bit of alpha- and beta-testing for manufacturers. While it’s time-consuming volunteer work, and requires meticulous attention to detail––even seemingly minor details––it gives me an opportunity to have meaningful positive impact on an upcoming product. Manufacturers that actively involve enthusiasts in their testing phase tend to produce better quality. I wish all manufacturers did this (yes, Tecsun, I’m looking squarely at you!).
After the Skywave SSB arrived, I started putting it through its paces. Typically, pilot run units have quirks and glitches buried in non-standard operating procedures. Try as I might, I couldn’t find any on the Skywave SSB. I’ve since learned that C. Crane invests heavily in pre-production testing; I saw their full list of iterative notes, and they were incredibly detailed. Result? No obvious problems. I’ve always believed that while C. Crane doesn’t always produce the most affordable products––nor do they stuff every bell-and-whistle into them––what they do produce is well thought out, user friendly, well documented, and performs at or near the top of its class.
Features
The CC Skywave SSB comes with a surprising amount of features for such a compact radio. Many of these features are also found on the original CC Skywave.
I’ve placed upgraded features in bold:
AM, FM, NOAA Weather band plus Alert, Shortwave (1711-29.999MHz) with SSB mode, and Airband
Frequency direct entry, plus auto scan and store
Lighted LCD display
Selectable fast or fine tuning (on all bands except weather)
Dedicated fine tuning control, selectable on front panel
400 memory presets
Runs on 2 AA Alkaline batteries (not included)
(Optional) CC Skywave AC power adapter w/ mini USB plug required for charging NiMH batteries.
Stereo headphone jack and fold-out back stand
Clock with 12/24 hour format and alarm
Rotary volume knob
Squelch control
High quality CC Buds Earphones and radio carry case included
Run Time (on batteries––approximate):
± 70 hours (earbuds)
± 60 Hours (built-in speaker)
10 Aviation Memories can be scanned for activity
You’ll notice there are actually very few obvious upgrades from the original Skywave to the Skywave SSB: just SSB mode, expanded HF coverage (from 1,711 to 29,999 kHz), and dedicated fine tune button/control. I’ve also learned that aviation band scanning is much faster on the newer model than on the original Skywave.
Other than those items, in terms of features, it’s very similar to the original CC Skywave.
Appearance
CC Skywave SSB (left) and the original CC Skywave (right)
The original Skywave and Skywave SSB are nearly identical in terms of form factor; overall dimensions are identical (4.8″ W x 3″ H x 1″ D), although the Skywave SSB weighs 1.2 oz more than the original––a difference that’s scarcely detectable.
The tuning knob, volume control, power port, and headphones jack are in the same places on the SSB. The chassis color is different, however; the original Skywave is black, whereas the new Skywave SSB is grey––a dark warm or “dim” grey,” to be accurate.
Original CC Skywave (left) and CC Skywave SSB (right)
Where one finds the true difference between the new Skywave SSB and its predecessor is on the front panel. The Skywave SSB has dedicated buttons to enable both SSB mode, select upper or lower sideband, and a fine-tune control. The Skywave also has a dedicated backlight button. This accounts for a total of four additional buttons compared with the original Skywave.
In a rather nice touch, both the SSB and fine tune buttons have tiny red LED indicators to let the user know when they’re engaged.
The CC Skywave SSB also has a redesigned speaker grill which more closely resembles the grill on their CC Pocket radio. Much to my surprise, once I shared detailed photos of the CC Skywave SSB, many of my readers expressed their disappointment with the speaker design. Many claimed it looked “cheap” as compared with the original Skywave and thus felt the chassis might be more subject to breakage. Some even got the impression that the speaker grill was raised in a way that it would lend itself to harm.
Actually, this is not accurate. Though it may appear that the speaker grill is elevated in photos, it’s actually in a recessed portion of the chassis and surrounded by an absorbent rubber ring, rising only ? 1 mm above the chassis, if that. And the hard plastic case feels as solid and robust as any portable I’ve tested. I wouldn’t hesitate to toss it in my pack.
Personally, I think the Skywave SSB is a handsome little radio! Perhaps I’m not as sensitive as others about chassis design, but I’m actually happy it’s not a clone of the original Skywave, making it much easier for owners of both models to distinguish them when packing!
From Pilot/Beta to production
While C. Crane allowed me to post a number of photos once the product announcement had been made, I would not publicly comment on performance. Indeed, I never post performance comments about pre-production units since I wouldn’t be evaluating the same product that hits the store shelves.
So once C. Crane posted an ordering page for the Skywave SSB, I placed an order, just like everyone else.
In truth, I was told there were only minor differences between the pilot unit and the production unit: some silk screening and other very minor changes.
Production Quirks
[IMPORTANT UPDATE: Again, please note that the following production quirks have been addressed in the second production run of the CC Skywave SSB. Click here to review the update.]
I was eager to get started on the review of the Skywave SSB, so as soon as I received it, I did what I always do: compared it with other radios!
I make my comparisons, by the way, at least fifty yards from my house to separate the radios from any inadvertent sources of local noise.
Production Radio #1
My first comparison was with the Digitech AR-1780 and the original CC Skywave. I quickly noted that the Skywave SSB was very slightly less sensitive than the other radios. I had tested the pre-production unit enough to know that the Skywave SSB’s performance should at least be on par with, if not a little better than, the original Skywave.
Upon careful listening, I discovered the production unit had a faint, internally-generated whine on some of the shortwave bands; when tuned to marginal signals, this whine manifested in the form of variable background noise. Between signals it was audible as a faint background whine, hardly noticeable. With that said, the whine was most notable while tuning––since the Skywave SSB mutes between frequency changes, the whine was most conspicuous during audio recovery between steps.
The pre-production unit had no trace of an internally-generated whine. Audio was very clean in comparison.
Here’s a sample of the first production radio being tuned down from 10,000 kHz in 5 kHz tuning steps:
I contacted C. Crane promptly, and to their credit, they immediately dispatched another unit from inventory, via UPS Next Day, along with a return label to send my faulty unit back to their engineering team.
Production Radio #2
The second unit arrived while I was on Thanksgiving vacation, but was sent to me directly at my hotel. The day I received the replacement Skywave SSB, I put it on the air. The first listening session with it, alone, revealed that this unit did not have the internally-generated whine, however, this unit had issues with sensitivity. All of my comparison receivers were outperforming this Skywave SSB on the shortwave broadcast bands. When I compared it with the pre-production Skywave SSB unit and the first production unit, the second production unit was about four to five S-units less sensitive…Odd.
I sent both production radios back to C. Crane with detailed notes and sample recordings. Their engineering team confirmed my findings and started looking into the variations in QC and double-checking their inventory to make sure none shipped with these problems.
Production Radio #3
A few days later, I was sent a third production unit. After putting it on the air, I immediately noticed the same faint noise characteristics of my first full production unit, which is to say, the notorious whine.
Once again, I contacted C. Crane. This time, I requested that no less than three radios be sent to me, and that they kindly expedite the request.
Production Radios #4, #5, and #6
I tested all three radios from this final batch of production units. What follows is an assessment of those radios.
First production run noises
I spent two full hours searching for birdies (internally generated noises) and other anomalies on the three CC Skywave SSB production units I received that Monday. Each radio’s noise location varied slightly (within 20-40 kHz).
Birdies
Birdies are a fairly common occurrence among sensitive receivers, and the CC Skywave SSB has about an average number. Fortunately, the birdies I noted are outside the space where I do my broadcast listening:
2,305 kHz
9,220 kHz
11,520 kHz
Background audio whine/tone
All of the production units (save Radio #2) had a very slight audio whine present––either via the internal speaker or headphones––on certain portions of the spectrum.
In the first full production unit I received, I believe this whine may have slightly affected the unit’s overall sensitivity. On the last three production units I received, the whine didn’t seem to have as much of an impact on overall sensitivity.
The whine is still there, however. And occasionally when the unit is tuned to a weak signal within one of these zones, other faint sweeping noises can be detected in the background.
Sometimes it’s even more noticeable when the broadcaster is weak and is located within one of the “whine zones.” Here’s an example of 10 MHz WWV time station comparing the original Skywave with the Skywave SSB. Note that at the time this was recorded we had terrible propagation due to a geo storm, so WWV was very weak, indeed.
Here are the frequency ranges where I noted the background whine:
7,830 – 8335 kHz
8,610 – 8,690 kHz (note: very faint)
9,770 – 10,415 kHz
11,585 – 11810 kHz
Another oddity is a noise I found prevalent on CHU Canada’s 7,850 kHz frequency. I’m guessing it may be due to the presence of a DSP birdie on top of a relatively strong broadcaster.
Here’s a video comparing the original Skywave with one of the production models:
I noted no birdies or noises on the mediumwave band.
I’ve no doubt, C. Crane will tackle these issues and solve them by the time the second production run ships.
In the meantime, I’ve become somewhat of an expert on the CC Skywave SSB, having evaluated a total of seven models and spending more time evaluating them than I have any other portable.
Let’s take a look at what we can expect from the CC Skywave SSB with these first production quirks aside.
Audio
Like its predecessor and many other travel radios (the Digitech AR-1780 and XHDATA D-808 being notable exceptions) the Skywave SSB’s audio from the internal speaker is adequate. It’s just shy of what I would call “tinny” because it does cover the mid-range . For spoken word content in AM and SSB, it does the job quite well. With music, you simply can’t expect any bass notes or room-filling audio. But then again, in a compact radio, my expectations are simply lower. The Digitech AR-1780 and XHDATA D-808 have the best audio of my compact travel radios, but they’re also the largest, so have a slightly bigger speaker.
I did note a minor amount of background hiss present somewhere in the audio amplification chain on the first production run units–most noticeable via headphones.
With the supplied CC Buds, you’ll be a happy camper.
Audio sounds rich via the headphones jack.
Performance
Of course, what we all want to know is how well the CC Skywave SSB performs. In a nutshell (spoiler alert!) it’s very similar to the original Skywave.
I break this down band-by-band below, starting with my favorite band.
Shortwave
Keeping in mind the frustrating experience with quality control, when I received the final three production units, I was very pleased with performance on the shortwave bands. The AGC characteristics are relatively stable, making weak signal listening a pleasant experience. Even though the Skywave SSB lacks a synchronous detector, I found that stability––even with periods of notable selective fading––is impressive.
In the realm of compact travel radios, both my pre-production and (better functioning) production models are strong performers. The Skywave SSB is slightly less sensitive than my larger, full-featured portables like the Tecsun PL-660, PL-680, PL-880, and Grundig Satellit. All of these radios, however, have longer telescoping whip antennas. If I add the gain from the included CC Reel antenna, the Skywave SSB can even hold its own with many of these.
I’ve been very pleased with the original Skywave for broadcast SWLing for a few years now. I’m happy to report that the Skywave SSB offers an incremental improvement over the original Skywave.
FM
Much like other modern DSP portables, FM performance is stellar for such a compact radio. The Skywave SSB was able to receive all of my benchmark FM stations. While audio fidelity from the Skywave SSB’s internal speaker is not a strong point, via headphones you’ll be quite pleased.
AM/Mediumwave
I’ve found the Skywave SSB to be capable mediumwave receiver. Performance characteristics are very similar to the original Skywave and the AGC settings even make MW DXing a pleasant experience. Since the internal ferrite bar isn’t terribly large, better performance can be achieved by coupling the Skywave SSB to an inexpensive loop antenna, like the Grundig AN200 AM Antenna.
Weather radio
Like the original Skywave, the Skywave SSB is an impressively capable weather radio receiver. From my home, I’m able to pick up a marginal NOAA weather radio frequency that most of my other weather radios cannot. The Skywave SSB also includes a handy weather alert feature that will monitor your chosen NOAA/Environment Canada frequency and wake up the receiver if an alert is issued.
Note that the weather alert feature works on a timer and, most importantly, if operating from battery, drains batteries as quickly as if you were monitoring a live station with the squelch open.
AIR band
While I didn’t compare performance with a triple conversion scanner, I’m favorably impressed with AIR band performance. During my tests, I noted no imaging or overloading on the AIR band, a very good thing. Additionally, the Skywave SSB offers improved scanning features for the AIR band, making it easier to monitor ground, tower, and even approach/departure frequencies at larger airports. When employing the squelch feature, you almost get the impression you’re holding a scanner, rather than a shortwave portable, in your hands.
Longwave
Like the original CC Skywave, the SSB does not cover the longwave band. In North America, there is very little to listen to on longwave, so many consumers will never take notice. I’m sure longwave DXers will wish it was a part of the package, however. Admittedly, when I’m traveling in Europe and other parts of the world where there are still stations on longwave, I’ll certainly miss the band.
Comparing to other compact travel radios
Trying to decide if the CC Skywave SSB will have the performance characteristics to displace my other travel portables, I compared it with the radios I mention at the beginning of this article.
In terms of overall sensitivity and selectivity, the CC Skywave SSB essentially runs neck-and-neck with, or in some respects slightly edges out, the Tecsun PL-310ET, Grundig G6, and CountyComm GP5-SSB.
However, both the Sony ICF-SW100 and the Digitech AR-1780 are more sensitive than the Skywave SSB. The Digitech AR-1780 has the best audio characteristics of the competitors, but is also slightly larger and heavier than the others.
Note, too, that the Sony ICF-SW100 and Grundig G6 are the only radios in this comparison that don’t mute between frequency changes. They’re the best band-scanning receivers.
And how does the Skywave SSB compare with the original CC Skywave? I find that the Skywave SSB has a slightly lower noise floor which is perhaps helped even further by better audio/tone characteristics. Sensitivity is about the same, but signals pop out of the background static better on the Skywave SSB.
In terms of features, the Skywave SSB likely offers the most for the traveler.
Summary
Every radio has its pros and cons, of course. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions. Following is the list I’ve formed over the time I’ve been evaluating the CC Skywave SSB:
Pros:
Overall well thought out, considerate design
Excellent form factor for travel
Very good sensitivity and selectivity for a compact radio
Faster AIR scanning compared with the original Skywave
Better HF frequency coverage than the original Skywave (1.711-29.999 MHz, compared to 2.300-26.100 MHz)
Pleasant SSB audio
Multiple bandwidths in both AM and SSB modes
No overloading noted
Well-written operation manual
Excellent weather band reception
Nice red LED indication lamps for SSB and Fine Tune engagement
Supplied with:
a quality external reel antenna
CC Buds earphones
Soft case with Velcro closure
Excellent battery life from two AA cells (AA cells are a plus for travelers as they’re so ubiquitous)
Engaging SSB mode requires 2-3 seconds of delay (common for this DSP chip)
Some ticking noise in audio when pressing buttons (identical to the Digitech AR-1780)
No RDS
No audio-out jack
No longwave reception
ATS Scanning in 1st production run stops at 26,100 kHz
No synchronous detection (though not expected in this class of compact portable)
Shortwave ATS tuning time about half as fast as the original Skywave (original is quite speedy!)
$149 $169 price is at the top of its class
Conclusion
I love the CC Skywave SSB. Sure, I wish it had RDS, an audio-out jack, didn’t mute between frequencies, and was a little less expensive. But overall, it’s a fantastic package. I’m impressed with the amount of performance the Skywave SSB provides with such a short telescoping antenna.
Most reading this review will be scratching their heads wondering if: a) having SSB mode is worth the $60 premium over the original Skywave ($89 vs. $149)? and b) is any compact radio, for that matter, really worth $149––?
Because of how I travel, I would say that I easily use ultra-compact portables like the Skywave SSB about 70% of the time I’m found listening to portables.
When the Skywave SSB was first placed on the C. Crane website, they posted a price of $169––when the units started shipping, they reduced the cost to $149, and reimbursed those who had placed an order with the higher price. [UPDATE: Early 2018, they once again increased the price to $169.]
Though the initial $169 price made me wince a bit, I still ordered one. Why? Because to me being a traveler who loves an ultra compact, having an ergonomic, full-featured, durable, compact travel radio with SSB, AIR and NOAA weather radio is worth it!
Therefore, the CC Skywave SSB will be my travel radio of choice going forward––it’s essentially a Swiss Army Knife of a travel radio.
There’s another factor, too: I trust C. Crane. Despite the frustrating quirks I experienced reviewing my first production run units, I know C. Crane takes care of their customers in the long run, and will replace any faulty units without hesitation. They’ve taken every item of feedback I’ve provided directly to their engineers and quality-control specialists, and the work continues to resolve this radio’s concerns. If you have a Skywave SSB with noise, don’t hesitate to contact C. Crane about it.
Overall, I am optimistic about this radio. I expect the second production run will produce radios performing as they should––like the final production units I tested, but without the internally-generated noises. [Click here to read second production run update.] And if this occurs as I expect, you can expect good performers.
At any rate, I know this: I’ll be one of the first to test units of their second production run…and to let you know just what I find. (Bookmark the tag CC Skywave SSB for updates.)
