Don Moore’s Photo Album: Santa Bárbara, Honduras

by Don Moore

I first set foot in Latin America in January 1982 when I arrived in Tegucigalpa to begin three months of Peace Corps training. Three months later I moved to my Honduran home, the town of Santa Bárbara in the western mountains. For the next two years I worked as a teacher and resource person at the Escuela Normal Mixta de Santa Bárbara, a specialized high school that trained its students to teach primary school.

Santa Bárbara had a shortwave station, La Voz del Junco on 6075 kHz but it was rarely reported because it broadcast irregularly and was usually blocked by big international broadcasters when it was on the air. I had never heard it but I met Miguel Hasbun, the owner-manager, on my first visit to Santa Bárbara when he picked me up hitchhiking north of town. He told me that the shortwave transmitter had been broken down for a while but that he was going to fix it ‘soon’. Over the next year I kept inquiring about the shortwave and he finally did fix it. After that the station broadcast irregularly for the next year or so, mostly in the morning. I served as volunteer veri-signer and issued around fifteen QSLs. I even issued one to myself.

Santa Bárbara had one other radio station, Ondas del Ulúa on 1140 kHz medium wave (later 1150 kHz). They also announced 4770 kHz shortwave in their canned IDs and station staff assured me they would be adding shortwave “soon”. It never did happen but the WRTH did list the frequency as future plans for several years.

Audio:

The department of Santa Bárbara had one other radio station, Radio Luz y Vida on 1600 and 3250 kHz in the town of San Luis. The founder, manager, and veri-signer for Radio Luz y Vida was a missionary from Oklahoma named Don Moore. Needless to say, this caused a lot of confusion in the DX world as some people assumed he and I were the same person. On the map, San Luis is only about thirty kilometers from Santa Bárbara but getting there involved a five-hour journey on two buses. I only went once and the other Don Moore was out of town, so I never met him. I did meet two nurses who were working at the mission’s health clinic.

The small tower on the left was the corner of what had been an army post but was being used as a regional prison in the early 1980s. I once went there every day for a week to supervise student-teachers doing adult literacy classes for the inmates. It was not a pleasant place to be.

Monitoring DSC with YADD

By Don Moore

(The following article was originally published in the April/May 2022 edition of the Great Lakes Monitor, bulletin of the Michigan Association of Radio Enthusiasts. An all-band listening club, MARE publishes a bi-monthly print bulletin and a weekly e-mail loggings tip-sheet. The club also holds regular get-togethers, picnics, and DXpeditions, generally in southeastern Michigan.)

There are dozens if not hundreds of different digital modes used for communication on the MF and HF bands. These aren’t broadcasts you want to listen to unless you like to hear weird tones, beeps, warbles, and grinding noises interspersed with static. Digital modes are for monitoring, not listening. And monitoring them requires having software that does the listening for you and converts the noises into something meaningful – like the ID of the station you’re tuned to. The learning curve to DXing digital utilities can be steep. There are lots of modes to identify and the software can be complicated to learn. Some broadcasts are encrypted so you can’t decode them no matter how hard you try. But the reward is lots of new stations and even new countries that you wouldn’t be able to add to your logbook otherwise.

One of the easiest digital modes to DX is DSC, or Digital Selective Calling. DSC is a defined as “a standard for transmitting pre-defined digital messages.” Look online if you want to understand the technical specifications that specify the values, placement, and spacing of the tones. The result of those specifications is a string of three-digit numbers like this:

125 107 125 106 120 105 120 104 000 120 022 120 041 000 002 022 020 041 108 002 053 020 080 108 006 053 021 080 070 006 118 021 126 070 126 118 126 126 126 126 126 126 126 126 126 126 117 126 112 126 117 117 117 112 109 125 108 125

Each three-digit value represents either a digit or a key word and the positions of the values map to the various fields contained in the message. This message, which was received on 8414.5 kHz, is a test call from the tanker Brook Trout to the coastal station Coruña Radio in Spain. The sender and destination are not identified by name but rather by their nine-digit MMSI (Maritime Mobile Service Identity) numbers – 538006217 for the vessel and 002241022 for the coastal station.

GETTING STARTED WITH DSC

Logging DSC stations requires three pieces of software. First you need a decoder program that turns the noises into numbers and the numbers into meaning. There are several free and commercial options but the most popular one for beginners is YADD – Yet Another DSC Decoder. YADD is free and easy to set up and while YADD can be used by feeding the audio from a traditional radio into your computer, the most common use is with an SDR. That’s what I use and what I will describe here.

Second you need an SDR application and an SDR. I prefer HDSDR for most of my SDR use but I like SDR-Console for digital work. But any SDR program will work if you can feed the audio to a virtual audio cable. And that’s the final thing you need – a virtual audio cable to create a direct audio connection between your SDR application and YADD. There are several different ones available but I recommend VB-Cable. Your first VB-Cable is free and that is all you need to run a single instance of YADD. If you want to expand you can buy up to four more cables from them later. Continue reading →

Don Moore’s Photo Album

by Don Moore

Introduction

When I discovered DXing over fifty years ago I also discovered the world. Through my ears I traveled to other countries and explored other cultures. But DXing has also literally taken me places. My early interest in Latin American DXing developed into a broader interest in Latin America. That led to me joining the Peace Corps after college and working three years in Honduras. That experience furthered my interest in Latin America and I have continued to travel in the region whenever possible. For me DXing and travel were always intertwined. I’m one of a handful of hobbyists who took DXing beyond just listening and went knocking on broadcasters’ doors to visit the distant stations I heard. My ex-wife dubbed this ‘door-to-door DXing.’

To date I’ve visited over 150 radio stations in thirteen countries. A few were medium-wave or FM only, but I was always most interested in visiting broadcasters that used shortwave, either at the time of my visit or a few years before. As my station visits were primarily made in the 1980s and 1990s, almost all of the stations are long-gone from the shortwave bands. However, many are still around on medium wave and FM and often also via streaming on the Internet. As much as I miss the magic of shortwave I know that these stations reach more listeners today via streaming than they ever did with their low-powered shortwave transmitters. Honestly, I sometimes enjoy tuning them in without the fading and static of shortwave. But the memories of what shortwave once was are still there.

Photos also bring back memories. I took dozens of pictures on my station visits and enjoy scrolling through them now and then. You may have seen some of them. Many of my photos were printed with articles I wrote for various DX publications and I’ve done a few slide-shows at DX get-togethers over the years.

In this series of columns I want to share my old photos once again. If you’ve been DXing as long as I have maybe they’ll bring back memories of what you once heard. And if you haven’t been around that long you will have a better understanding of the good old days we oldtimers talk about.

Ecos Del Torbes

There is no better place to start this journey than with Ecos del Torbes. Using ten kilowatts on 4980 kHz, this Venezuelan broadcaster was possibly the most consistent station in the sixty-meter band throughout the 1970s, 80s, and 90s. If you were DXing the tropical bands during those years you surely logged them a few times. If you were lucky you may even have heard their one kilowatt signal on 9640 kHz. They were a very good verifier and for many DXers Ecos del Torbes was among the first Latin American stations QSLed.

Just after Christmas in 1994, my then-wife, four-year-old daughter, and I flew to Mérida in western Venezuela for a family vacation. For ten days we had a great time in this Andean city and then Theresa and Rebecca returned to Iowa while I stayed another week to visit radio stations. I was also getting paid by the Voice of America to research and write a study on the media scene in Andean Venezuela. The now very-out-of-date report can be read at my Patepluma Radio website (which hasn’t been changed in over twenty years and is in need of a facelift).

In that week I visited fifteen radio stations in six towns and cities and Ecos del Torbes was the highlight. I arrived at their doorstep unannounced but was immediately treated as an important guest. I was given a great tour and even got to sit in on a live newscast to see the famous Venezuelan doorbell being used live. I was there about ninety minutes and then walked a block up the street to sister station Radio Táchira. Their facilities were smaller but that’s where the technical offices were and Chief Engineer Ivan Escobar had been told to expect me. Ivan gave me a tour and invited me to visit the Ecos del Torbes transmitter site with him in the afternoon. On the way we stopped by his house where his wife had lunch waiting for us. Visiting Ecos del Torbes was not just the highlight of this trip but ranks as one of my all-time favorite station visits. These pictures bring back many good memories.

Ecos del Torbes was located in the second floor of this building in downtown San Cristóbal. The entrance was the door on the side.

The small plaque next to the door was easy to miss. I walked right by the first time.

Edgar Fabala of the news department showed me around. Here he demonstrates the mini-xylophones that Venezuelan stations used to make the distinctive ‘doorbell’ sound that separated items in the news reports.

San Cristóbal once had a third broadcaster on shortwave. Radio San Sebastian used 6070 kHz in the early 1970s. (They were not affiliated with Ecos del Torbes).

That was nearly three decades ago and a lot has changed. Ecos del Torbes and Radio Táchira have been gone from shortwave for over twenty years.

In 1995 Ecos del Torbes was at the corner of Calle 9 and Carrera 8, the same address as when I first QSLed them in 1972. Sometime since my visit they moved an outer neighborhood about two kilometers to the east. To find the new offices locate San Cristóbal on Google maps and then search for “Grupo Radial Gonzalez Lovera”. The transmitter site is still where I visited it and can be seen by plugging the coordinates “7.7885, -72.2725” into Google maps and switching to satellite view. (Ignore the picture that pops up to the side. That’s not it.) Zooming in, the medium wave tower is clearly visible but there are no signs of the old shortwave antennas. I suspect they were sold for scrap years ago. I never have found out where the Radio Táchira transmitter site was.

I’d love to go back to Venezuela someday and see some of the other cities that I used to listen to, such as Barquisimeto, Valencia, El Tigre, and Sucre. Unfortunately the political and economic situation there doesn’t look good and it doesn’t look as if it will improve any time soon. But when it does, I’ll be back.

Guest Post: An Introduction to DXing the MF Marine Bands

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

Monitoring the MF Marine Bands

By Don Moore

For me, DXing has always been about the challenge of receiving difficult-to-hear radio stations, regardless of the type of station or frequency range. In my five decades in the radio hobby I’ve logged a lot of different kinds of stations – shortwave broadcast, medium wave, shortwave utility, longwave beacons, etc. But some of my favorite catches have been in the upper end of the medium frequency range.

Technically speaking, medium frequency (MF) is the range from 300 to 3000 kHz and includes the standard medium wave (AM) broadcast band. The upper end of the MF band, from 1600 to 3000 kHz (except for a small portion reserved for amateur radio),  has always been assigned to various types of utility uses including broadcasts and other voice communications from regional maritime stations. And while digital modes and satellites have done a lot to change the nature of communication with ships at sea, there is still a lot of good human-voice DX to be heard.

Several dozen stations, mostly in Europe and North America, broadcast regularly scheduled marine information broadcasts in the MF range. These broadcasts are usually between five to ten minutes in length and include weather forecasts, navigational warnings, and other notices to keep ships at sea safe. On occasion it’s possible to hear two-way voice communication here between ships and shore stations, although that’s much less common today.

The Equipment

Nothing special is needed to DX the marine MF band other than a receiver that covers the frequency range and can receive USB mode (which all these broadcasts are in). However, for reasons explained below, I highly recommend using an SDR to make spectrum recordings of the entire band to go through later. Continue reading →

The Rarest DX?

By Don Moore

In mid-October I received an invitation to attend the annual DXpedition in Cappahayden, Newfoundland with Jean Burnell, John Fisher, and Jim Renfrews. It didn’t take long for me to say yes. Newfoundland is one of the best places in the world to DX from and all kinds of amazing stuff has been heard there. I was excited at the prospect of great medium wave DX and being able to log low-powered European private and pirate shortwave broadcasters.

But something else was at the top of my try-for list. One of my many DX interests has always been logging coastal marine stations in the 1600 to 3000 kHz range. In preparation I started checking online sources to update my spreadsheet of schedules. In going through a recently added section on Marine Broadcasts in the DX Info Centre website I came across listings for twice-daily weather broadcasts from Hopen Island on 1750 kHz and Bjørnøya (Bear Island) on 1757 kHz.

I didn’t remember ever seeing anything about broadcasts from these remote islands in the Norwegian Arctic before. Were these stations actually on the air, I wondered. And if they were, could I hear them in Newfoundland? Continue reading →

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.

A Visit To Radio Tarma

By Don Moore

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.

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.

The reason for Radio Tarma’s continued presence on the sixty meter band is Mario Monteverde, Radio Tarma’s energetic owner-manager.

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.

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.

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!

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!

If shortwave conditions aren’t the best, you can always listen to Radio Tarma on the web.

Wow–Don, this was amazing. Thank you for taking us on a tour of the amazing Radio Tarma! What a special station to encounter during your travels!
