Many thanks to SWLing Post contributor, Jason Whiteley, who writes:

Hi Thomas,

[T]here is a really interesting interview with Radio France here around their DAB+ expansion and the possible shut down of FM in France later [click here to read].

I used Google Translate to bring it to English.

[Y]ou might also choose to link to this article about AM radio being dead in Europe (written in 2015):

https://www.radioinfo.com.au/news/am-radio-dead-europe

The article is bang on though – AM radio is still very strong and thriving in Australia & the USA. Here in Australia at least, it’s DAB that has a minimal audience compared to traditional AM broadcast.

I just found both of these articles very interesting reading and thought you might like to put them up.

Have a great day,
Jason

Thank you very much for sharing these articles, Jason! Earlier today, we posted a note about digital AM here in the States (AM HD). There is a movement to increase this offering, but for true market penetration it would require car radios that can receive AM HD. Many a DXer dislikes AM HD because the digital signals are (unlike DAB+) inserted between analog signals. These band crowding sometimes causes interference to adjacent analog stations and certainly affects mediumwave DXing.

Radio World: Bryan Broadcasting Asks FCC to Allow All-Digital AM

5 Replies

(Source: Radio World via Ulis K3LU)

A prominent advocate for the AM band is petitioning the FCC to allow stations to use all-digital transmissions in the United States.

Bryan Broadcasting Corp. on Monday filed a petition for rulemaking asking the commission to initiate a proceeding to authorize the MA3 all-digital mode of HD Radio for any AM station that chooses to do so.

Permitting such modernization would “give AM broadcasters a needed innovative tool with which to compete” without harming others in the spectrum ecosystem, it wrote.

Bryan is licensee of four AM stations, five FMs and six FM translators in Central Texas. Ben Downs is the vice president and general manager, and submitted the petition along with the company’s attorney David Oxenford of Wilkinson Barker Knauer. Downs also has served on the NAB board in the past, and he has been a vocal advocate for various regulatory steps to “revitalize” the AM band.

All HD Radio receivers in the market that have AM functionality would be able to receive such all-digital signals. But legacy AM receivers would not, which has long been a barrier to serious discussion of all-digital. Now, some observers say, the availability of FM translators for AM licensees has made something that once seemed unthinkable at least worth discussing.

There is one AM station in the country with special temporary authority to broadcast in all-digital. Hubbard’s WWFD in Frederick, Md., near the nation’s capital has been on the air since last summer. The station’s Dave Kolesar has been speaking in public about the ongoing experiment and will do so again at the upcoming NAB Show.[…]

The Hip Spot On Your Dial

by The Professor

I’m old enough to remember when they first pulled the oldies radio concept out of the box and plugged it into the wall. And it literally was a gadget. A machine. I was a kid in suburban Detroit in the early 1970’s when I found one of very first all “oldies” stations to go on the air. The station (which started on FM, then simulcast on AM and eventually became an AM station), and then became known as “Honey Radio.” There were no DJ’s, just jingles, commercials and lots of dated top 40.

Automatic or not, the programming of Honey Radio was immediately intriguing to me and some of my friends at the time. As the album rock format was wandering deeper into crap like Uriah Heep and Kansas, I’d impatiently fumble with the dial looking for something (anything) different and kept perching the needle on this new station that played only old rock and roll. Half of it I’d never heard before.

It’s hard to imagine now, when most oldies stations play such a tight and boring playlist, but the original oldies format was born in the “American Graffiti” (and then “Happy Days”) era, when old rock and roll was immediately more evocative and uplifting than the arena rock epic thud and guitar solos that were clogging up the album rock format.

From what I recall of early Honey Radio format, the music spanned from 1955 until 1967 or ‘68. I started soaking it up– Rockabilly, r&b, doo-wop, even dopey pop. I loved it all (okay, except Neil Sedaka…). And it filled in a missing chapter in top 40 history for me– between my mom’s record collection and the music I had been hearing on the radio since diapers. Listening to the station turned me on to a whole world of recording artists I barely knew before (and ones you probably won’t hear much on oldies radio nowadays), like Huey “Piano” Smith, Ral Donner or the Impressions. And not just the big canonical hits, but other choice tracks that charted too. All that from a robot radio station.

A little later (after I’d stopped obsessively listening), Honey Radio added real DJ’s and in the final tally had a good run as Detroit’s premiere oldies station until shutting down in the early 90’s. The demise of Honey came as the format’s followers were surging into middle-age, and the new thinking in advertising advocated virtually abandoning that once valued demographic. This shift in advertising strategy drove more and more oldies outlets to desperately expand their playlists into the hits of the1980’s, and drop almost all the 50’s and early 60’s music that fueled the original format.

There are some good, even interesting, oldies stations that are still out there (WLNG, for example). And a few brave ones have popped up and bucked the era-shift gentrification of the oldies format, and specialized in the early rock era with music libraries much larger than the mind-numbing 300 tested superhits that make up the format in most markets. However, these days radio stations exist in a cutthroat environment, where anything but sucking in big piles of money every day isn’t just unacceptable. It’s fatal. The profit margin possible with creatively (or lovingly) programmed oldies radio is almost never enough to keep these stations alive for very long. It’s not that true-blue oldies stations don’t attract a loyal audience, it just isn’t big enough or young enough to have a chance in the dog-eat-dog world of contemporary radio advertising. That is, unless you happened to have purchased a radio station for a really reasonable price, and making a fat profit isn’t necessarily your goal. Then you have choices. Then you have WHVW.

A true media miracle, WHVW in Hyde Park/Poughkeepsie, New York, is the ultimate oldies station for the culturally inspired fan of American roots music. While there’s a number of hosted regular programs, the majority of the WHVW’s air time is occupied by a music automation system, otherwise known as “Murray the Machine.”

Programmer/owner “Pirate Joe” Ferraro has radically expanded the oldies format with Murray. But instead of following the present-day model of stretching the format forward in time and taking on dodgy material, Joe has lopped off the late 60’s music and everything that followed. No psychedelia, no bubble gum, and thankfully no Jim Croce. While he’s held on to the doo-wop and rockabilly of the classic 1955 to 1964 era (adding a helping of folk music that was popular at the time), the rest of library goes further back in time. But unlike the hit parade highway you might hear on senior citizen radio, Ferraro opts for the rural routes of r&b, blues, old jazz, and classic country. All and all, it’s the rockin’ 20th century– an “oldies” overview based on favorites of record collectors and the kind of music that kept people putting nickels in jukeboxes for decades. While I haven’t done a scientific study of all the ingredients of Pirate Joe’s automated format, but I can tell you one thing– it’s compelling, and unlike any radio station I’ve ever heard. And it makes a lot of sense.

For the last decade or so, I’ve had family in Poughkeepsie, which places me within the transmission range of WHVW a few times a year.  I’ve stacked up a number of airchecks of WHVW over the years– mostly captures of Murray on the job. But what a well nursed and well-fed automation system Ferraro has set up. No matter how many tapes I’ve gathered of his automation over the years, it always sounds fresh.

While the Pirate Joe’s music machine does a heck of a job, there’s a skeleton crew of real live on-air personalities who keep WHVW human as well, and fun to listen to. Like Pirate Joe (who does a wonderful afternoon drive weekday shift himself), the DJ’s musical appetites are mostly variations on Joe’s musical themes– record collector/characters who live and breathe old jukebox shakin’ hits and rarities. Curt Roberts, the morning drive guy goes for more of an eclectic golden oldies approach, adding some soul and garage sounds to the mix. And what a voice. And the personalities of Roberts and Ferraro set the tone for the on-air persona of WHVW– wry and dry and isn’t the music great. It’s straight-forward– rarely exuberant and rarely boring. And I like it.

I don’t get up in WHVW territory enough to know the schedule well, and their website (which looks like it was put together with mid-90’s know-how) usually seems a bit out of date. But you can see what the official schedule was late last year here (the link to this page has mysteriously fallen off the home page). And while it’s not much a web site, there is some history of the station and a few pictures. And sadly, they do not stream their air signal there (or anywhere). But if you want to get an idea of some of WHVW’s glowing fan mail, Joe has posted a bit of it on this page.

One show that’s been a Sunday mainstay for well over a decade now is Darwin Lee Hill’s “Real Hillbilly Jamboree.” It’s a three hour hand-crafted hootenanny, featuring  hits & obscurities from all the classic country music sub-genres, as well as some more recent material from neo-traditionalists and aging legends. That said and all technical descriptions aside, Darwin’s show is consistently warm and informative radio, including occasional interviews with country legends. And the music is always heartening. Kinda makes you wanna buy a second home in Poughkeepsie.

I wish I could say that WHVW could be the harbinger of a new creative era of AM music programming. But I’m a realist, and there’s little reason to think that the glory of this little radio station is much more than fortunate happenstance. As his nickname implies, Ferraro is a former radio pirate, someone with synergistic mastery of musicology and old radio technology, who happened to get a good deal ($350,000) on a lowly class D AM station. While there’s still bargains like that around, they’re more likely in desolate North Dakota or rural Mississippi. WHVW is located in an actual city (albeit a small one), surrounded by the fringe suburbia of New York City. It’s a convergence that brings a big chunk of musical Americana to the radio dial in a place where people really live and play, or at least drive through on their way to Albany.

And the station doesn’t operate in a vacuum, WHVW really serves the community. They have locally oriented talk shows and local news, something you don’t hear very often these days on stations with far larger budgets and bigger transmitters. And requests from listeners carry a lot more weight when the DJ actually programs their own show. For folks who live in the mid-Hudson Valley who love great (and occasionally obscure) old music, WHVW must be a godsend.

For those who might have dreams of snatching up a cheap radio station and running it on a shoestring, Ferraro’s WHVW offers an intriguing model. Two people on staff (including the owner) handling the weekly drive-time slots and then a roster of weekly volunteer hosts doing shows for the love of it (and perhaps the advertising they can generate), with the rest of the broadcast day filled with the offerings of a tasteful and compelling automated music mix. This way a small radio station can maintain a local connection and eschew the predictable dependency on pre-packaged music formats and syndicated talk shows. And I think that WHVW disproves the bias of a number of non-conformist radio types I’ve known who equate radio automation with a lack of imagination or laziness. It all depends on who’s programming the machine.

Now in the age of mp3 players, I suppose you could spend a couple of years loading up on thousands of old shakin’ and stompin’ classics and kinds create your own WHVW in your pocket. But it would still be an imitation of Pirate Joe’s musical vision. Which is on the air right now by the way. Filling the sky of Dutchess Country with radio waves carrying the likes of Coleman Hawkins, T-Bone Walker or Harry “The Hipster” Gibson, proving that automated radio can be a non-conformist’s best friend. And that it’s not impossible for a radio station to be a better music machine than a money machine.

Many thanks to SWLing Post contributor, Dave Snyder, who shares the following in reply to our previous post about a chunk of the WOWO fire escape in lucite:

Thomas,

Have you ever visited “www.historyofwowo.com“–?

This site was put together by Randy Meyer and has hundreds of photos from 95+ years of broadcasting. Many pictures are from me as I worked there from 1969 to 1982. The link below is to the promotional items page where there is another picture of the “World Famous WOWO Fire Escape” chunk of steel cast in lucite.

These were made in 1978 after the station moved from the Gaskins Building to the Central Building. (By the way, the Central building is no longer there.)

The Gaskins Building was a dismal place with no windows. The air and news people had to open the door to the fire escape to see if was sunny or raining. That is why the local temperature was from the World Famous Fire Escape. My piece of fire escape is in a box in the basement.

Many thanks for sharing this, Dave! WOWO is such an iconic AM station with such a deep history–I’m grateful all of these photos and history are being archived and shared online.

Thrift Store Find: A $2.50 GE Super Radio II

8 Replies

A few weeks ago, I stopped by our local Habitat For Humanity ReStore searching for reclaimed building supplies.

This particular ReStore is one of the largest in the area–it has an amazing selection of building supplies, furniture, housewares, books and even music, but has a very small section dedicated to electronics which is primarily stocked with DVD players, VCRs and occasionally the odd component system. The person who sets the prices for electronics always over-inflates them so it seems items sit on the shelf for ages.

In all of the years I’ve visited this store, I’ve never found a portable radio of interest…until a few weeks ago.

As I passed by the shelf, a GE Super Radio II caught my eye. Cosmetically, it was in rough shape (in other words, “well-loved”).

I expected a $50 price tag but instead was surprised when I saw $2.50! I put on my reading glasses just to make sure I was reading it correctly.

I plugged the radio in and tested it on FM. It easily snagged a number of FM stations and the audio sounded amazing although the loudness, treble and bass pots were very scratchy.

The AM broadcast band worked as well, but the RFI/noise inside the retail warehouse was overwhelming.

I opened the back of the radio and found an immaculate battery compartment. Obviously, the previous owner was either diligent with removing cells when not in use, or never used batteries.

The antenna was in great shape and had no bends or breaks.

The speakers were in tact as well.

I took the radio to the counter and the guy who rang up the order said, “Well…she ain’t pretty, but for $2.50 how can you go wrong?”

My thoughts exactly!

I brought the Super Radio II home with the idea of immediately cleaning her up (like David Korchin did with his “barn find” II), but I’ve had a couple intense travel and work weeks, so it had to wait.

Fast-forward to yesterday when my father-in-law was in town and stopped by for a visit.

He mentioned in passing that after his favorite public radio station decreased power from one of its translators, he could no longer receive it easily with his small AM/FM portable at home. Of course, I have at least four dozen radios here that could easily receive this station, but few of those include a power cord, are incredibly simple to operate and have room-filling audio.

I took a look at the GE Super Radio II, then a look at my father-in-law, and decided he needed it. I knew the ‘Super II would make him a happy man.

I quickly dusted off the chassis and cleaned the pots with DeOxit–it played like a new one.

I tuned to an FM station playing classical music, turned up the volume and my father-in-law beamed when he heard the rich, clear audio.

No doubt, this time-honored portable will get a lot of use and love in its second life.

If I’m being honest with myself, this might not have been a truly altruistic move. You see, when we do an overnight at my father-in-law’s house, I can now do a little AM DXing without having to lug one of my own receivers!

A win-win in my book.

Radio Travel: A complete SDR station for superb portable DXing

5 Replies

Many thanks to SWLing Post contributor, Don Moore–author of  Following Ghosts in Northern Peru–for the following guest post:

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.

Airport Security

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.

For fun, here are some of the better places I DXed from in Peru, Ecuador, and Colombia. The key thing to look for is an open place for the antennas:

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.

Photos from the 2019 Charlotte Hamfest

This RS HF receiver was pristine. If I had the budget and the shack space, it would have gone back with me. See more photos in our gallery below.

Yesterday morning around 5:30 AM I started my nearly three hour pilgrimage to the 2019 Charlotte (North Carolina) Hamfest. The Charlotte Hamfest is one of the larger regional hamfests in the area–due to its central location, it attracts people from all of the surrounding states.

The Charlotte Hamfest typically falls on the heels of (or the same weekend as) the Winter SWL Fest in Pennsylvania so I usually don’t even put the dates in my calendar. Indeed, the last time I attended the Charlotte Hamfest was about twenty years ago! It was at a different location and, back then, was also very much a computer show. Today it’s almost purely radio.

Following Vlado to the hamfest site on a very foggy, rainy Saturday morning.

The Charlotte Hamfest is a Friday/Saturday event held at the Cabarrus Arena & Events Center in Concord, NC. The center is a superb hamfest venue: it’s well lit, clean, spacious and can easily house all of the vendors indoors–a huge bonus as weather was less than desirable.

My buddy, Vlado (N3CZ) reserved two vendor tables and packed it with gear to sell–I also brought along a handful of items.

I was very impressed with the turnout–indeed, it was one of the busiest regional hamfests I’ve attended in ages. I sold a couple of items and Vlado sold a lot (he also purchased a lot, but that’s another story!).

I believe I’ll start putting the Charlotte hamfest in my calendar–even though timing isn’t always convenient for me, I think it’s well worth the trip!

Kudos to the Mecklenburg Amateur Radio Society for putting on such a great show!

I’ve embedded over 140 photos of the Charlotte Hamfest below–click each one to enlarge. Being a lover of vintage radios, my photos feature a lot of boat anchors. Note that when possible, I try to include the price tags for each item.
