Last week, we packed the car and headed to coast of South Carolina.
The trip was a bit impromptu but through the creative use of hotel points, we scored a two bedroom ocean front unit with a fantastic little balcony.
The vacation gave me an excuse to test the new passive loop antenna my buddy Vlado (N3CZ) helped me build recently.
The loop design came from AirSpy’s engineer and president, Youssef Touil.
This passive mag loop takes advantage of the new AirSpy HF+ Discovery‘s exceptionally high dynamic range. Youssef had reported impressive results, so I had to build one.
Vlado had a length of Wireman Flexi 4XL that was ideal for this project. The only tricky part was penetrating the shielding and dielectric core at the bottom of the loop, then tapping into both sides of the center conductor for the balun connections. Being Vlado, he used several lengths of heat shrink tubing to make a nice, clean and snag-free design.
The results were truly exceptional. I spent most of my time on mediumwave from the hotel balcony because I was determined to catch a transatlantic signal.
Check out the spectrum display from my Microsoft Surface Go tablet:
Our ocean front hotel was inundated with noise, but I still managed to null out most of it and maximize reception using the passive loop. I simply suspended the loop on the balcony rocking chair–not ideal, but effective and low-profile.
Want to take a test drive?
If you’d like to experience this portable SDR setup, why not tune through one of the spectrum recordings I made?
The recording was made on November 17, 2019 starting around 01:55 UTC–I chose it at random and have yet to listen to it myself. You’ll need to open this file in AirSpy’s application SDR# or a third party SDR app that can read AirSpy .wav files.
I’m writing an in-depth report of the HF+ Discovery, my experiments with this setup and AirSpy’s soon-to-be-released passive loop antenna for the January 2020 issue The Spectrum Monitor magazine. Spoiler alert: I am truly impressed with the wee little AirSpy HF+ Discovery. It’s a powerhouse!

I recently returned back from a three-month trip in Africa (Namibia, South Africa, and Morocco) and had a couple of shortwave-related items that you might be interested in.
The rental car in Namibia had shortwave capabilities in the in-dash radio! The rental company was oblivious to the option when I mentioned it as a huge perk, I really don’t think they understood or cared. The radio was a Sony CDX-G1200U, and while I find this radio for sale in North America, I don’t see any mention of shortwave. I suspect shortwave is either an option for foreign markets (at least Namibia in this case), or possibly activated via a modification or firmware upgrade. Perhaps any shortwave enthusiasts travelling to other regions of the world might keep an eye out for this model.
There were two ‘bands’, low (SW1) included some of the tropical bands up to 41 meters, and high (SW2) covered 31 meters through about 19 MHz or so. Decent coverage for casual mobile listening.
I found the performance of the radio quite satisfactory in Namibia, the BBC came in very well in the mornings and evenings. There was a little more on shortwave during the day in English, Channel Africa, etc., but the BBC was by far the best offering for listening.
Another equipment data point from around the world, this time in Morocco.
Several vendors in the Medina’s sold various radios (of questionable quality). The photo [above] was taken in Tetouan (which isn’t a touristy area) in March, but I did note similar for sale in Fez.
Brilliant, Rob! It sounds like you’ve visited some gorgeous parts of the world in your travels. I imagine on the long stretches of rural roads in Namibia, you could enjoy a proper low-noise environment for shortwave listening as long as the car itself didn’t produce RFI!
Post readers: Have you driven a car recently that sported a shortwave radio capabilities? Please comment!
One of my favorite DXing locations was this little cottage at the El Rancho Hotel just outside San Ramon, on the edge of the Amazon jungle in Peru. At $18/night, including breakfast, the hotel was a bargain, and there was plenty of room for my delta loop.
A Guide To Vagabond DXing
By Don Moore
Ever since I served as a Peace Corps volunteer in Honduras in the early 1980s, Latin America has been my primary focus for both DXing and traveling. So when I retired in 2017, my main goal was to begin taking long annual trips . . . and I do mean long. From October 2017 to May 2018, I traveled through Peru, Ecuador, and Colombia visiting about fifty different towns and cities. This year, I’m on a five-month trip through southern South America. In Latin America you can get just about anywhere cheaply and easily by bus, so that’s how I get around. It’s also a great way to meet people and to see the countryside. But luggage can become a burden, so I limit myself to a single mid-sized wheeled suitcase and a large knapsack. And that means that my mobile DX shack has to be very carefully planned.
Your plans may not include multi-month odysseys like mine, but I think my experiences will help you prepare to DX on your next trip, wherever it might be. Of course, what makes a good mobile DX shack depends on what your DX interests are. I consider myself a station collector, in that I want to make loggings of lots of new and different stations and to build up an understanding of radio broadcasting in different regions. So on my travels I concentrate on the medium wave broadcast band and longwave beacons, with maybe little bit of shortwave utility DX. (There’s not much on shortwave broadcast that I can’t also hear at home.)
Take the DX Home With You
For years my standard DX travel gear was a Sony ICF-2010, a cassette recorder, and an old Radio West ferrite loop antenna. But listening time was always limited since it was a vacation. There were other activities on the agenda and I was generally too tired to get up early for DXing. I always went home with some interesting loggings and audio recordings, but once I left for home the DXing was done.
SDRs have changed all that and now my first rule of travel DX now is take the DX home. The best souvenir of a trip is the hundreds of hours of DXing that I take home with me. In a 2016 trip to central Colombia, I made about 300 MB of recordings of the medium wave band. While listening to them later I logged over 400 stations from twenty countries (and I still have about half the files to go through). I never would have even gotten close to that many stations listening on my Sony like an ‘old-fashioned’ DXer, hi!
Lately, I’ve been accumulating SDR files much faster than I could possibly go through them, so it’s a fair question to ask what the point is. When will I ever listen to them all? Like most DXers, I’m not fortunate enough to live in a perfect DX location. When conditions are mediocre, I’d rather spend my DXing time going through some more interesting SDR files. And, I know I’ll have lots of good DX waiting for me years from now when I’m no longer able to travel the way that I do now. For me, SDR recordings make much better souvenirs that some cheap tourist trinkets that will gather dust on a shelf. It doesn’t matter whether your travels take you to a nearby park or to a distant continent. SDRs can preserve the DXing experience for years to come.
My Mobile DX Shack
This is my typical DXing setup with the Afedri. The rooftoop terrace at the Hotel Rosa Ermila ($10/night) in Cascas, Peru was the most elegant place I’ve ever DXed from, but reception was only average with the PA0RDT dangling from the railing.
The centerpiece of any DX shack is the receiver. On my 2017-18 trip, I had an Afredri SDR-Net with an SDRPlay RSP1 as a backup, but this year I replaced the Afedri with an Elad FDM-2. Together, my two SDRs are smaller than all but the smallest portable receivers. Of course I also need a laptop, but I’m going to take one anyway. An important consideration in selecting a travel SDR is to get something that is powered off the laptop’s USB connection so that it is easy to DX totally off battery power if line noise becomes an issue.
The other vital component of DXing is the antenna. A good on-the-road antenna for SDR DXing has to be small, easy to erect, broadband, and versatile. That sounds like a lot to ask, but the perfect DX travel antennas do exist.
For compactness and ease of use, nothing can surpass the PA0RDT mini-whip. How good is it? That’s what I used to log over 400 medium wave stations in Colombia in 2016. I just attached the unit to my coax and threw it about three meters up into a short tree. The antenna works best when mounted away from nearby structures, but sometimes I’ve gotten decent results placing the PA0RDT on balconies and windowsills of tall buildings. It’s mostly a matter of luck as to how bad the local noise levels in the building are and how much the building itself may block signals. Using a short support, such as a broom or a hiking pole, it may be possible to mount the unit a meter or so away from the building.
While it’s best to mount the PA0RDT away from obstructions, the antenna might give good results anywhere, even on the neighbor’s roof. (Just make sure it’s not likely to get stuck. Pulling the unit out of a stubborn papaya tree is no joke.)
The biggest drawback of the PA0RDT for serious MW and LW DXing is that it is non-directional. For a directional antenna, a Wellbrook loop is great if you’re traveling by car, but that one-meter diameter aluminum loop doesn’t fit in my suitcase. Fortunately, a few years ago Guy Atkins and Brett Saylor told me about an alternative: buy a Wellbrook ALA-100LN unit and attach it to a large homemade wire loop. Now my travel kit includes two nine-meter lengths and one eighteen-meter length of #18 stranded copper wire. The wires can be spliced together for loops of 9, 18, 27, or 36 meters circumference, according to what fits in a location. Erection of a wire loop is easy enough with a suitable tree branch. I just throw the wire over the branch and then form it into delta (with the bottom running just above the ground) using two tent stakes and some short cord to hold the corners. The ALA-100LN unit goes in the bottom center.
Items that go in my suitcase, left to right: tent stakes and wire for the Wellbrook loop, a small box with more adapters, another battery box, 50 foot coax, 12 foot coax, and my hiking pole. The pole doubles as a support for the PA0RDT sometimes.
The loop doesn’t have to be in a delta; that’s just often the easiest to erect. I’ve successfully used squares, rectangles, trapezoids, oblong diamonds, and right angle triangles. Any balanced shape with the ALA-100LN in the bottom center should be bi-directional in a figure-eight pattern. Non-balanced shapes will work equally well but with unpredictable directionality. Just keep the wire in a single plane and place the ALA-100LN unit someplace along the bottom.
Both the PA0RDT and the Wellbrook require a 12V power supply. The North American version of the Wellbrook comes with an excellent noise-free 110V power supply, but that’s of no use in 220V countries and also I want to be able to DX totally off battery power when necessary. Fortunately both antennas use the same size power connector, so I carry three eight-cell AA battery packs for remote power.
Contents of the DX box, clockwise from upper left: the two pieces of the Wellbrook ALA-100LN, the two pieces of the PA0RDT mini-whip, two 8xAA battery boxes and a set of batteries, USB and coax cables, a passive 4-way antenna splitter, battery tester, various adapters and cup hooks (for securing wires), 4TB hard drive, the SDRPlay RSP1, the Elad FDM-2, and more short patch cords.
My mobile DX shack is rounded out with everything that is needed to connect the parts together. I have at least four of every adapter and patchcord, since I know they won’t be easy to replace on the road. For lead-ins, I have 12-foot and 50-foot lengths of lightweight coax with BNC connectors. I also have a few F-to-BNC adapters so I could buy some standard TV coax if needed. A 4 TB hard drive provides plenty of space the SDR recordings I plan to make. (Before leaving, I fill it with videos that I can delete after I watch them or when I need space.) For DX references, I download various station lists online so that I have them available even if I don’t have an Internet connection. It’s also important to keep those lists with the SDR files from the trip so that if I’m listening to the files years from now I’ll have references which were current at the time.
A common concern for traveling DXers is getting through airport security. When I went to Colombia in 2016, I wrapped my DX gear in clothing for protection and then stuffed everything into my backpack. Security didn’t like what they saw and I had to empty the bag so that every single item could be examined and swabbed for explosive residue. The TSA lady was very nice about it, but I wanted to minimize the chance of that happening again.
At an office supply store I found a plastic storage box that fits inside the main pocket of my backpack. My SDRs, antenna components, and hard drive get wrapped in bubble wrap and all placed together in the box along with small cables, adapters, etc. Larger items – the wire, coax, and stakes for the loop – get packed in my checked bag.
The DX Box packed and ready to go.
At the airport, I slide the box out of my backpack, place it into a cloth shopping bag, and then send it through the X-Ray machine on its own so that the agent can get a close look at the contents. So far in about a dozen security checks in the USA, Peru, and Mexico, the box of gear hasn’t caused so much as a pause on the conveyor belt. And, if the box would get pulled for a closer look, at least I won’t have to empty the entire backpack again.
Most of my equipment fits in this plastic box which slides into my backpack.
Where to DX
A mobile DX shack isn’t worth anything without a suitable place to DX from. Hotels may work if you have a balcony where you can put a small antenna, but more likely than not there’ll be problems with RF noise. The best hotels are ones that are a collection of cottages or bungalows or that otherwise have an open yard-like space for an antenna. My favorite place to find possible DXing sites is on AirBnB. It’s often easy to find AirBnBs that are on the edge of town or even in the countryside with lots of space. Of course, since I don’t have a car, I need to make sure I can get there using public transportation.
While visiting Huanchaco, Peru with DX friends Karl Forth and John Fisher, we had a beach-front apartment with an adjoining rooftop terrace. We had excellent results with an oblong loop and the ALA-100LN on the terrace.
The key to selecting a DX location is to examine all the photos very carefully. Is there open space for the antennas? Are there trees or other potential supports? Is there a gazebo, terrace, or other space that could be used for DXing? Google satellite view and Google street view can be very helpful in scouting out a location (And it’s surprising how much of South America is now on Google Street View.) And, I always look for possible noise sources. One place I almost rented in Colombia turned out to have high voltage power lines running next door when I found it on Street View.
I always tell the hotel staff or AirBnB host what I’m doing so that they understand why the gringo has wires running around. And I make sure not to put my antennas or coax anywhere that might interfere with the employees or other guests. Most of the time I’m able to erect the antenna near my room and run the lead-in into my room through a window. Then I can leave my laptop running all night to make scheduled SDR recordings. That’s the Holy Grail of DXing – catching the overnight DX while you sleep. But if my room turns out to have too much RF noise (as has been the case a few times), then I head out to the gazebo or terrace to DX using battery power. That does mean I have to stay up late or get up early since I can’t leave the laptop outside on its own. But, some of the best DX that I’ve had has come from running off full battery power in gazebos.
My delta loop had plenty of space at the Posada de Sauce ($25/night with breakfast) in the jungle near Tarapoto, Peru. The lodge was totally powered by solar panels and was one of the quietest places I’ve ever DXed from.
Antenna security is another consideration. At one place I stayed I wasn’t comfortable leaving my expensive antenna components unattended outside all night. And then there was what happened on my first trip to Colombia in 2010. I knew that a place I would be staying at for two nights had an open field right behind it, so on that trip I took 500 feet of thin insulated wire for a mini beverage-on-the-ground. DXing was great the first night but terrible the second. When I went out the next morning to wind up the wire I learned why. The worker who had been weed-wacking the hotel gardens the previous day had also done the field, and in doing so he had cut my wire in three places. He had, however, very nicely tied the wires back together.
Share the DX
DXing off battery power in the gazebo in the Mauro Hilton Hostel in the mountains above Manizales, Colombia. The antenna was the PA0RDT thrown in a tree. I had great DX with the loop from my room, but I came here to enjoy the views one evening.
Finally, if you take an SDR on a trip and get some good DX, make a selection of your files available for download. Other DXers will enjoy hearing what the band sounds like somewhere else. Several dozen of my files from Peru, Ecuador, and Colombia are available for download in a shared Google Drive folder. If you see something you want, be sure to download it now. The winter DX season is just starting here in deep South America and in the coming weeks I’ll be replacing some of those older files with ones made in Argentina and maybe in Uruguay and southern Brazil. I’ve found a lot of places to stay that look to be perfect for a vagabond DXer.
The PA0RDT miniwhip – see the email address at the bottom of the article for ordering information. I highly recommend getting the original PA0RDT. There are several cheaper versions for sale, but DXers have reported quaility control problems with those.
Don, thank you so much for sharing your travel DXing expertise. This article is absolutely brilliant and so informative for anyone who wishes to make SDR field recordings. I love how carefully you’ve curated and distilled your portable setup and have given priority to having antennas for all occasions. I also think carrying spare parts and, especially, a spare SDR makes a lot of sense.

Radio Tarma building
Shortwave stations in South America are few and far-between these days, but those of us who have been tuning the bands for a few decades remember the days when the tropical bands were filled with Latin American broadcasters from dozens of scattered mountain and jungle towns. One such place was Tarma, a picturesque but chilly city of about 50,000 nestled in a narrow valley in the central Peruvian Andes at 3,000 meters above sea level. Tarma has been an important commercial center since colonial times and archaeological findings indicate that the region was heavily populated long before the Spanish came. Today it sits at the junction of two major trade routes, so it continues to be a bustling place.
View of northern Tarma from the Radio Tarma transmitter site
While wandering around central Peru in April 2018, I made a point of stopping in Tarma so as to visit the town’s namesake broadcaster, Radio Tarma, one of the few Peruvian stations still on shortwave. Radio Tarma’s frequency of 4775 kHz has been a fixture on the sixty meter band for over four decades. What I didn’t know was that this would turn out to be the best of the over one hundred Latin American station visits that I have made in my travels.
Radio Tarma Frequencies
When I first stopped by on Monday afternoon, everyone was busy and no one had time for a visiting gringo. By chance I had arrived on the station’s sixtieth anniversary and they were preparing for a big celebration that night. I was invited to come back in the evening when there would be a huge street party with live music. That evening I got to talk to several members of the station staff and was introduced to owner-manager Mario Monterverde, who invited me to come back for a tour in two days after the celebrations and ceremonies were over.
Radio Tarma’s 60th Anniversary Party
The Radio Tarma Party Band
Radio Tarma Owner/Manager Mario Monteverde
The reason for Radio Tarma’s continued presence on the sixty meter band is Mario Monteverde, Radio Tarma’s energetic owner-manager.
Mario Monteverde in the old record library.
Running radio stations is his passion, and that includes reaching distant listeners on shortwave. Don Mario remembers what shortwave used to be like in Peru and he can rattle off station names and frequencies from past and present as good as any serious DXer. We spend a lot of time talking about stations I used to hear and the ones that I visited in my 1985 trip to Peru. We mostly talk in Spanish, although he speaks English well. He studied in Lima and later in the United States for several months. In the 1980s, he lived in San Francisco for a year while working as a DJ at a Spanish language FM station.
Don Mario thinks that it’s unfortunate that there is so little use of shortwave in Peru today, but other radio station owners think he is crazy to continue to use shortwave. The only listeners to shortwave in Peru are peasants in jungle settlements and remote mountain valleys. That may be a suitable audience for a religious broadcaster, but these listeners have no value to commercial stations, such as Radio Tarma, as they are mostly outside the money economy and of no interest to advertisers. But Don Mario doesn’t care and so Radio Tarma continues to broadcast on shortwave several hours every morning and evening for whoever might happen to tune in.
Studio for Radio Tarma
And, Radio Tarma can afford to broadcast as it sees fit. Don Mario’s Grupo Monteverde is one of the most professionally run and profitable communications companies that I have visited in Peru. In addition to Radio Tarma (on MW, FM, and SW), the company operates two television stations in Tarma, the local cable network, the local FM repeater for Radio Programas del Peru (Peru’s radio news network), and Radio Tropicana, a chain of FM music stations in Tarma and three nearby towns.
Founded in 1958 by Mario’s father, Radio Tarma was the first radio station in this city. Using two homemade 500 watt transmitters, the station initially broadcast on both medium wave and 6045 kHz shortwave, but the shortwave went off the air after about a year. Then in 1978, Mario’s father dusted off the old shortwave transmitter and applied for a new license. He was granted 4770 kHz, but that was soon changed to 4775 kHz, where Radio Tarma has been ever since. In the past four decades, Radio Tarma has been logged by thousands of DXers all over the world and, although it’s hard to believe, when I visited Tarma in April 2018 they were still using that original 500 watt transmitter that Mario’s father built sixty years before. However, a new one-thousand watt solid state transmitter was currently in Lima being tested by the Ministry of Transport and Communications. It should be on the air by now.
Studio for Radio Tropicana’s Tarma station
Don Mario starts by giving me a tour of the station building and its well-equipped offices and studios. He shows me the closet where the transmitter for the studio-to-transmitter-site link is and then takes me upstairs to the record library. Radio Tarma has one of the largest and oldest collections of vinyl records in the Peruvian Andes and includes numerous rare recordings. Many of the disks are EPs, or extended-play, which was once a very common format in the Andes. These records are the size of a 45 but recorded at 33 rpm so that there are two songs on each side. Don Mario keeps the records for their value but they aren’t used on the air anymore as Radio Tarma and its sister stations are all fully computerized. When there’s time they work on digitizing the better historical recordings from their collection.
Radio Tarma mountaintop transmitter site
After seeing the studio, we get in Don Mario’s four-wheel drive SUV for the trip up a steep and winding dirt road that leads to the mountaintop transmitter site. For most of the station’s history, Radio Tarma broadcast from a field on the north side of town.
Radio Tarma’s pre-2012 transmitter site was in the large field in the center of this photograph.
Then in 2010 Don Mario decided to modernize by buying a modern 3000 watt solid-state transmitter for the medium wave frequency and by building a modern transmitter facility on a ridge overlooking town. The new site, which was inaugurated in 2012, is at 3,600 meters elevation (over 600 meters higher than Tarma) and located about 1.5 kilometers south of the old site. (If you’ve logged Radio Tarma both before and after 2012, I think it’s fair to count these as two different transmitter sites.)

Radio Tarma MW and FM masts
The transmitters and antennas for all the Grupo Monteverde stations in Tarma (MW, FM, SW, and TV) are housed in the gray fortress-like cement building covered with a jungle of antennas and satellite dishes, for both receiving and transmitting. All of Peru’s main cellular services have towers nearby, as do several other FM and TV stations in Tarma, but Radio Tarma has the best location, right at the end of the ridge overlooking all of the town. For shortwave, Radio Tarma uses a dipole antenna strung between two masts.
Radio Tarma’s shortwave dipole
The transmitters and other technical equipment are all housed in a large room that takes up most of the first floor of the building. Upstairs there is a small apartment, complete with a living room and kitchen, for the technician who lives here plus another small apartment where Don Mario comes to stay when he feels like escaping to the quiet mountaintop for a night or two.
Radio Tarma SW and three MW transmitters
Radio Tarma transmitter room
Don Mario takes pride in showing me the original 500 watt medium wave and shortwave transmitters that his father made. Normally the shortwave service is shut down for several hours in midday when the frequency won’t propagate, but he turns on the transmitter so that I can see the tubes come to life. The three medium wave transmitters – the original 500 watt one, its 1978 1000 watt replacement, and the new 300 watt solid-state one – are lined up against the wall adjacent to the shortwave transmitter.

Alfonso, transmitter operator at Radio Tarma
Don Mario tells me that the two older medium wave transmitters are regularly maintained so that they could be used at a moment’s notice if needed. He then proceeds to show me that he means just what he says, and shuts down the solid-state transmitter. Once that’s down, he powers up the original Radio Tarma MW transmitter that his father made, and we watch the old tubes light up. Then when it’s operating fully, he turns his father’s transmitter off and switches on the 1978 transmitter for a few minutes before finally returning the signal to full power on the new transmitter. One wonders just what his listeners thought was happening with all this on-and-off transmitting on a beautiful sunny day barely a cloud in the sky!
View of southern Tarma from the transmitter site
Radio Tarma and the Grupo Monteverde are a model operation for radio in smaller cities in the Peruvian Andes. Getting to know both the city and the station was one of the highlights of a seven-month journey through the northern Andes in South America.
Don Mario’s father built the foundation and Don Mario turned Radio Tarma and its sister stations into the small but professional media group that they are. He’s now in his mid-sixties and plans to run the radio operations for several more years. But he is beginning to think of the future. He never married and has no children, his siblings live in Spain and Lima, and all his nieces and nephews are in the United States. It’s not likely that anyone in the family would return to Tarma to run a radio station. He is investigating options of how to set up the corporation so that Radio Tarma and its sister stations would continue as locally-owned and operated radio broadcasters. Whatever he works out, let’s hope it includes a commitment to continue broadcasting on shortwave for many years to come!
Looking back, I realize that I never posted this article on the SWLing Post.
Since we’re in the midst of the summer travel season here in the northern hemisphere, I thought I’d post this feature from five years ago.
I’m also adding a number of photos I took at the Radio Canada International Sackville, New Brunswick, transmitting site–one of my stops on this trip. I only recently rediscovered these (400+) photos in my archive and I’ve yet to curate them and post a proper photo tour. Look for that in the coming months.
After you read this article, I’d love to hear where you plan to travel this year in the comments section of this post! Enjoy:

A Radio Vacation: escaping RFI in an off-grid vacation cabin
If you’re like me, a vacation–or, for that matter, any kind of travel–is an excellent reason to pack up your radio gear. I nearly always travel with a shortwave radio, and typically with some portable recording equipment. If space allows, I also pack a small QRP transceiver–specifically, my Elecraft KX1–even if I know my opportunities to get on the air may be limited. But on an extended family vacation? Well, that affords some excellent hamcation possibilities!
Last year , our family had a golden opportunity: to spend an entire month in an off-grid cabin on the eastern coast of Prince Edward Island, Canada, some 2,500 miles from our home in the US.
Permit me to paint a picture of this little spot of paradise: the rustic cabin is nestled on a 22-acre site on a beautiful eastern bay. From the cabin’s large front windows facing the bay, there is a long-range view of Panmure Island and, further still, of the Georgetown marina.
The view from our off-grid cabin on Prince Edward Island.
As the site is wooded to the rear of the cabin, the environ feels very isolated from the rest of the world; no other homes or outbuildings are visible. And although off-grid, this little cabin sports simple versions of all of the comforts of home: propane gas meant that we always had hot water, a working refrigerator/freezer, and light after sunset in the form of two wall-mounted gas lanterns. Meanwhile, running water was provided by a unique “on demand” petroleum-powered pump.
While to some readers, this may not sound like paradise, this charming cabin gave our family a front-row view of nature’s varied character, from the shimmering sunsets over PEI’s famed terra cotta sands or the last stormy lashes of Hurricane Debbie, to the front-yard wildlife in the form of woodpeckers, owls, gulls, egrets, foxes, mink, and even “Black-Eyed Susan,” our resident raccoon. “Off-grid,” meanwhile, afforded all of us a refreshing break from those electronic devices we often become so –with the exception of radios, of course!
On the return route, we planned to take a driving tour of the Gaspe region of Quebec, via the New Brunswick Acadian coastline. Having made the decision to spend four weeks in the little cabin, I instantly started preparing my radio equipment.
As you can imagine, an isolated off-grid cabin poses some serious power-supply challenges for a radio hobbyist, but the benefit is a completely RFI-free zone. In truth, not only was I ready for the challenge, I was enthusiastic about it!
It’s worth noting that on most days of the week, I wear two hats: that of radio hobbyist and that of radio-based humanitarian organization director, Ears To Our World (ETOW). At ETOW, we work in classrooms located in very remote, rural and impoverished parts of the world, delivering appropriate support technologies, such as radios, to those who need them most. While in the isolated setting, I charged myself with the task of testing some of our solar and self-powered technologies–specifically, a portable power pack made by GoalZero called the Escape 150, and several portable panels and chargers made by the US manufacturer, PowerFilm Solar.
Living in an off-grid cabin for a month would give me the necessary time to evaluate the charge/discharge times and simulate the “real life” usage these items would experience in the developing world. Fortunately as a radio hobbyist, I had the means to put that powerpack to the test! My two radio-inspired passions combined harmoniously in this venture.
All told, all the radio equipment and power supplies I packed consumed no more space in our van than two standard suitcases. Even after packing, we found we had room to spare–the children in their carseats had plenty of room to swing their feet. So, we set our compass on due north, and set out!
Two nights in Sackville, New Brunswick
En route to Prince Edward Island, it’s hard to miss the (now) former Radio Canada International transmission site in Sackville, New Brunswick. The massive site, with its array of curtain antennas and large sign, is a fixture on the Trans-Canada Highway. Only a few months earlier, I had learned that RCI had been dealt devastating cuts by the CBC and that Sackville’s days were numbered; as a result, I felt I had to make a pilgrimage to the site before it was dismantled.
I arranged to tour the site, and was warmly greeted in Sackville. Though the staff were dealing with the oppressive news of the pending cuts, were bravely doing their professional best to carry out their duties as usual. The site was immaculate, the transmitters humming. On my tour, I took as many photos as my digital camera would hold, and soon I found myself taking up the cause, mentally working out an action plan to save it from total dismantlement. For many years, this site has been a landmark near the New Brunswick/Nova Scotia provincial line, and I hope in some capacity it will remain there, even for history’s sake. This relatively remote part of Canada has broadcast memorable events and news to every corner of our globe. It seemed a shame to undo the work of so many previous years. And indeed, the petition I authored this fall has garnered over 600 signatures, so it is clear there are many that feel the same. The decision is now in the hands of politicians.

Many, many thanks to my amazing tour guide, Marcel Cantin, who gave me unfettered access to the RCI Sackville site. Merci bien, Marcel!
Arriving at the cabin
After leaving Sackville for Nova Scotia, we took the Wood Islands ferry across the Northumberland Strait and arrived at our cabin well before dinner time. The morning after arriving at our little off-grid cabin, I sprayed myself down with a little insect repellent and spent an hour installing an inverted vee. I’ve found that, instead of pre-building an antenna, it’s easier for me to conduct a site assessment and simply put the pieces together in a configuration that makes sense. That’s the great thing about temporary QRP antennas: no soldering required. I simply fed my antenna with ladder line, used a PVC “T” joint as a center insulator and large plastic buttons for the insulators at the end of the legs of my antenna. I held the whole thing together with wire nuts and black electrical tape. Yet because it was electrically sound and balanced, it worked like a charm. Indeed, I didn’t even worry about the length of the radiating elements since I had my Elecraft T1 auto antenna tuner on hand.
That Sunday morning, I set up my entire ham radio and shortwave listening station all before my family was ready to venture out for the day. That afternoon, I worked stations in the US, Canada, and many of the islands in the Caribbean. I was delighted, to say the least.
Off-grid ham fun
My Elecraft K2 and Elecraft T1 combination was working beautifully on all bands down to 80 meters. I found that, even with heavy use, the K2 required very little of my 30 aH battery. Each day, I charged the battery with two of my foldable 5 watt PowerFilm Solar panels fed in parallel (equating to 10 watts). I never ran out of power for the K2 and had enough surplus to easily power some 12V LED lanterns, as well.
I was most impressed with the performance of my solar-powered Elecraft K2–no doubt, the very close proximity of salt water (perhaps 200 feet from the antenna) and the height of my inverted vee both helped. Though I worked some CW, I made more SSB contacts than I typically make while portable. I even found that I punched through a couple of pile-ups. Some kind operators also noted me on DX watch lists, and I found myself on the other end of mini pile-ups. Most encouraging were the numbers of other QRP stations I worked, even on SSB. In short, I was having a great time…!
I brought four receivers with me on this trip, the plan being to compare their reception: a Winradio Excalibur, Bonito RadioJet, Sony ICF-7600GR, and a Tecsun PL-380. Shortwave radio listening in this coastal spot was nothing short of amazing. In my band-scanning, I heard many of the international stations audible from my southern-US home, like Voice of Greece, All India Radio, Radio France International, the BBC World Service, and Radio Australia.
Listening to the final broadcast of Radio Netherlands on Prince Edward Island.
Though I planned to do some serious 2 MHz spectrum captures on my WinRadio Excalibur, I had not taken one thing into account: the amount of noise that the built-in modified sine wave inverter on the GoalZero Escape 150 generated. It overwhelmed the Excalibur and rendered listening useless. I could have easily remedied this, had I realized that the input on the WinRadio receiver required a steady 12VDC–I could have used an appropriate battery and never bothered with the inverter. The RadioJet, meanwhile, performed quite well, though my laptop’s battery had a hard time supporting itself and the receiver for more than an hour without the need of a total recharge. While the GoalZero Escape 150 power pack performed very well with DC usage, the inverter could drain a full charge in less than two hours of use.
Any given morning during that vacation, you would find me lounging in front of the cabin’s large glass windows–often watching the sunrise–and listening to CKZN in St. John’s, Newfoundland, on 6,160 kHz–a CBC Radio One shortwave relay in Newfoundland. Though I can hear CKZN back home when conditions are just right, it’s faint. On PEI, however, it was armchair listening as I sipped my morning java.
Sadly, I lost two shortwave broadcast companions on that trip to PEI: Radio Canada International, and Radio Netherlands Worldwide, each of whom played their final broadcasts. In both cases, I listened. Most notable were RNW’s final hours, as they actually broadcast tributes throughout the day, targeted at North America. I actually made several recordings from our cabin, and have posted them online: https://swling.com/blog/2012/07/radio-netherlands-says-farewell-in-style/
Top of the Cape Bear Lighthouse
What’s more, I even got to relive a little radio history in our travels. On PEI we visited the Marconi Station at the Cape Bear Lighthouse. According to lighthouse staff, this little station was one of the first (they will claim, the first) to receive the distress call from the Titanic.
View from the Cape Bear Lighthouse
An amazing bit of history from this wind-battered, rusting little lighthouse perched on the edge of a small cliff now being undercut by the Atlantic waters, as are so many along that eroding coast. The station tour includes a lot of radio history to this effect, but unfortunately the radio operation display is completely inaccurate: I seriously doubt any Marconi operator used a Heathkit to hear the Titanic distress signal. (Consequently, if any generous radio historians have a Marconi station they would like to donate, this deserving Lighthouse Society would greatly appreciate the fitting gift.)
On the final leg of our trip, we visited another Marconi Station at a breathtakingly beautiful lighthouse–Pointe-à-la-Renommée–where it stands on a bluff overlooking the mouth of the St. Lawrence on the very northeastern tip of Quebec’s Gaspé peninsula. This station, sited by Marconi in 1904, has many historic displays with original photographs spanning the decades, copy from messages sent and received, and a guided history of the station. Pointe-à-la-Renommée also features a very respectable collection of telegraph keys and Marconi console receivers. But the red lighthouse itself is the real show-stopper, with its gorgeously-faceted crystal above a charming lighthouse keeper’s house and cluster of outbuildings, on the green wind-swept bluff dotted with wild strawberries, and surrounded by the dark blue Atlantic waters far below.

Field Day with the Charlottetown Amateur Radio Club
Field Day coincided with our summer vacation, too, and I hated to miss hanging out with my local ham buddies on my favorite event day of the year. I decided to attempt to turn this relative misfortune into an opportunity: before we left on vacation, I did a bit of research and learned that there would be a Field Day event near Charlottetown, PEI. After a few inquiring emails, I discovered that this Field Day site was only twenty minutes from where we were staying. The stars had clearly aligned.

On Field Day, I was greeted most warmly by the good folks at the Charlottetown ARC. They instantly took me in as one of their own–offering food and drink, and chatting with me as if I had always been a part of their club. Best of all, when Field Day officially began, they put me on the mic on 20 meters. Evidently, they decided it would be fun to hear me announcing their callsign on the air in my southern accent. They got what they asked for! From the moment I took the mic, I had almost an instant pile-up; not because of my accent, however, but because Charlottetown offered one of the few stations on PEI, and the opportunity for participants to log the Maritime section.
I spent the better part of Saturday with them and hated to leave. Upon returning to the cabin and my family, I found that my artistic wife had created a little birthday present for me: a watercolor painting of my Vibroplex single-lever paddle. Truly, the key to my heart. (Ahem!)
It was a wonderful Field Day, after all.
Both the family vacation and my personal “hamcation” were a treat, and I’m ready to do this all again in the near future. Having such an extended stay made all of the difference, as I didn’t have to squeeze radio in, nor was it in competition with our other plans. Rather, radio became the thing I turned to when we were relaxing in the cabin, when my kids were drawing or playing, and my wife painting or reading–during our laid-back interludes between exploratory outings and adventures.
My Elecraft K2 turned out to be a superb off-grid transceiver
I did learn a few things about playing radio completely off-grid. First of all, my QRP field events (like Field Day, FYBO, FOBB, etc.) had me totally prepped for off-grid ham radio. In fact I didn’t forget a single connector, battery, tool or accessory. Setting up my outdoor wire antenna was a simple matter and I had fun on the bands, even though propagation wasn’t always perfect.
What did surprise me was the number of times I turned to my portable shortwave radios over my PC-controlled receivers. Simply put, a good portable radio connected to a random length wire antenna gave the right amount of performance vs. battery consumption. Though the SDRs performed better when hooked up to my inverted vee, they used quite a lot of battery resources since both my laptop and the receiver had to be powered.
If I could go back in time, I would have left the Excalibur at home, brought a general coverage portable transceiver and/or a dedicated tabletop receiver like my Alinco DX-R8. Capturing spectrum on a very RF quiet island location is very appealing, though. To make it work, it would require that I bring a separate 12VDC power supply and spare laptop batteries. With a modest PV system to recharge the batteries, it would also require constant planning–deciding when and where to listen, in order to recharge.
Most of all, I discovered that no matter where you go, as a ham radio operator, you will find others in your fraternity that will take you in. Field Day is one of my favorite days of the year and spending it with the good folks of the Charlottetown PEI Radio Club made it all the better. Not only did they get a kick out of hearing a southern accent announce their station on the air, but I got a kick out of being on the other end of Field Day pile-ups.
Hamcations don’t have to be month-long ventures, however. Even squeezing a little radio time in can be fun. A portable shortwave radio tucked into your suitcase on an extended business trip or a portable QRP transceiver on a week at the beach can add to your holiday fun–and if you’re lucky, create a few memories, and possibly even friends.
[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: 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.
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
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.
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.
[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 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:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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:
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
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 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
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.)
Many of you likely know I’m fascinated by remote islands and communities–especially the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha.
If you’ve been an SWL for a few decades you likely also remember the very popular Radio St. Helena day! We’ve posted several articles about it in the past–click here to read through our archives. I really miss that annual listening event.
The other day, while browsing sailing videos on YouTube, I uncovered this excellent little documentary about St. Helena via Deutsche Welle. Enjoy:
