Because I [purchased a RT-470L last year], Radtel sent me news of their brand new RT-860. No need to mod the radio like a Quangsheng. It does LW/MW/SW with SSB/CW (rx only, of course) out of the box for less than $50! I just posted a short preliminary review of the RT-860 on YouTube:

I’ve wanted to do a feature on Guatemala ever since starting this series a few years ago. From a cultural perspective it’s one of the most fascinating countries in Latin America. About half the population are indigenous, primarily Mayan, and most of them still speak their own languages. For several decades Guatemala’s religious broadcasters – Roman Catholic and Evangelical Protestant – used many of those languages on shortwave where we DXers were able to hear them.
I made five visits to Guatemala from 1982 to 1984 while in the Peace Corps in Honduras and returned in December 1987 while in graduate school. I spent enough time in Guatemala that there’s an entire section of my Vagabond DXer book filled with stories of my travels and station visits. In this seven-part series you get to see the pictures.
The map below shows the country, minus the sparsely populated northern department of Petén. We’re going to start in the least interesting part of Guatemala, the east. There’s very little indigenous culture left in that region nor much else of interest to the visitor. But you do have to pass through it to get from Honduras to the rest of Guatemala … and there were some radio stations to visit.
The main border crossing between Honduras and Guatemala has always been near Esquipulas in southern Chiquimula department. (That’s where the header photo comes from). But about 40 kilometers to the north is a secondary crossing near the town of Jocotán. In the 1980s, the road was rough and unpaved and the best mode of transportation was hitching a ride in the back of a passing pickup truck. The border consisted of just two wooden shacks, one on each side, minded by bored soldiers. That’s where I entered Guatemala on my second visit in June 1983. Jocotán had a radio station that I wanted to visit.
Eastern Guatemala may not have had much of interest, but the large Mayan ruins of Copán are just across the border in Honduras. The most direct route there from Guatemala City is via Jocotán so typically a few backpackers pass through town every day. I found a room at the Pension Ramirez. At $1.50 a night it was the perfect place for Peace Corps Volunteers, backpackers, and others at the very bottom end of the budget travel scale. I got a bed with sheets that may have been washed within the past week, a table, a chair, and a dim light bulb hanging from the ceiling. The shared bathroom was down the hall. Cold water only. But the Pension Ramirez had one thing that I never encountered at any other such lodging. The owner had a business card.
Jocotán was home to Radio Chortís, a Roman Catholic broadcaster that mostly ministered to the Chortí Indians who lives in the region. As most of the Chortí had assimilated into the dominant Spanish culture the station primarily broadcast in Spanish with just a few hours in the Chortí language each week. Radio Chortís used to put a strong signal into North America on 3380 kHz. The station was part of a mission funded by donations from Belgian and West German Catholics. The studios and offices were in a large complex that also included vocational training facilities and a print shop for the church. That explained why the back of their QSL letters always had a colorful station graphic.
Radio Chortís, 3380 kHz, as heard in Pennsylvania 30 December 1979 at 1152 UTC:
Early the next morning, I took a bus to Chiquimula, the departmental capital. DXers may recognize the town as the location of Radio Verdad, the last active shortwave broadcast station in Central America. It came on the air long after my time there so I never got to visit the station. In Chiquimula I switched to a bus bound for Guatemala City, but that wasn’t my final destination. I got off at a little crossroads just before the town of El Progreso and then boarded the next bus heading north to Cobán, capital of Alta Verapaz.
In Cobán I planned to visit another Catholic broadcaster, but one with a rather unusual name for a religious station. In the 1520s, the Spanish conquistadores quickly overran most of Guatemala but the Kekchi Indians in their mountainous homeland proved impossible to defeat. The Spanish dubbed the region Tezulutlán from an archaic Spanish phrase that meant “Land of War.”
In the 1540s, the Spanish tried another method to subdue the region, this time allowing Dominican friars under Bartolomé de las Casas to attempt to convert the Kekchi to Catholicism. Where the soldiers had failed the padres succeeded and the newly pacified region was renamed Verapaz, or Land of True Peace. Bartolomé de las Casas was a good man who left a legacy of trying to protect the rights of the Indians in a time of brutal conquest. But he was just one man in a time of boundless greed. He left the region a few years later and the Kekchi were forced into peonage just as the Mayans elsewhere in Guatemala had been.
And so four centuries later when the Roman Catholic diocese in Verapaz, the land of true peace, set up a radio station they named it Radio Tezulutlán, after the land of war. Someone had a keen sense of irony. But maybe there is something symbolic there as well. The Kekchi, after all, have survived as a people with their own language intact. Today they number over half-a-million, or almost eight percent of the Guatemalan people. That Radio Tezulutlán broadcasts primarily in Kekchi, not Spanish, might just be a final victory for the Kekchi.
The next few pictures show the Radio Tezulutlán building and studio from 1983 and the QSL card and pennant that I picked up on my visit. The QSL was for their little-used frequency of 3370 kHz. They mostly used 4835 kHz.
Radio Tezulutlán, 4835 kHz, as heard in Pennsylvania on 24 December 1979 at 1153 UTC:
In Santa Bárbara, Honduras, where I was living in 1983, one of the best heard Guatemalan medium wave stations was Cobán’s Radio Norte on 680 kHz. I stopped by in the evening hoping to pick up a QSL but the only person there was a lone announcer who was too busy to help me. I may not have gotten the QSL but I did pick up something that I’ve since come to see as even more valuable.
In my book, I explain how one of the primary sources of income for small town radio stations in that era was reading personal announcements and greetings on the air. The Radio Norte announcer had a stack of forms that listeners had filled out with messages to be read on the air. He was throwing away some that had already been read, so I took one.
The form could be either mailed to the station or hand-delivered, as this one apparently was. The message is a birthday greeting from Imelda to her son Mario Agusto. At the top, the date the message is to be read is listed and the place is listed as San Juan Chamelco. This is important as the announcer would first say something like “Atención! San Juan Chamelco!” to get the attention of listeners in that town. At the bottom are instructions as to when the announcement should be read – the 18:30 marimba music show. The form is a very unique radio station souvenir. I only wish I had taken the entire pile out of the trashcan.
Radio Norte, 680 kHz, recorded in Cobán during my June 1983 visit:
I also made a side trip to the neighboring town of San Pedro Carchá where I got a sort-of-QSL from Radio Imperial on 925 kHz. If you’ve read my book you know that a picture of the secretary would be a lot more interesting than this one of the front door.
For thirteen years the Roman Catholic church and Radio Tezulutlán had the Kekchi language airwaves all to themselves. But Evangelical Protestantism had been gaining ground in Guatemala for several decades and in 1988 the Evangelical station Radio Kekchi began broadcasting on the shortwave frequency of 4845 kHz. Radio Kekchi must have had friends at the Ministry of Communication as that assigned frequency was just 10 kHz above Radio Tezulutlán’s 4835 kHz. That certainly made it easier to poach listeners from the competition.
In one more bit of strangeness, Radio Kekchi was located sixty-five kilometers northeast of Cobán in the town of Fray Bartolomé de las Casas. So the Evangelical radio station was put in a place named after the priest who originally converted the Kekchi to Catholicism. Maybe the region should be renamed The Land of Irony.
Radio Kekchí, 4845 kHz, as heard in Ohio on 5 September 1988:
In much of the common literature about Guatemala it says that the indigenous people speak Mayan dialects. And back in the day when these stations were active on shortwave, DXers’ loggings often referred to hearing Mayan dialects. But I called Chortí and Kekchi languages, not dialects. What’s the difference?
Linguistically, a dialect is a regional variation of a language. The different dialects of a language are always mutually intelligible. American and Britons speak different dialects of English but have no trouble understanding one another except for the occasional confusion over a word or phrase. Speakers of Spanish and Portuguese can understand one another a little bit but not enough to have a real conversation. Those are distinct languages.
On the other hand, Danes, Norwegians, and Swedes have no trouble carrying on a conversation with each speaking their own language. That’s because linguistically they are speaking dialects of the same language. So why are Danish, Norwegian, and Swedish considered different languages? Linguist Max Weinrich once explained “a language is a dialect with an army and a navy.” He might have added an economy, a government, and international respect.
Languages spoken by people who are held in low prestige are often called dialects not for any linguistic reason but simply out of prejudice. It’s a subtle way of indicating these people and their culture are of less importance. This is true not only of Guatemala’s indigenous languages but of many others around the world. Chortí, Kekchi, Quiché, Cakchiquel, and all the other two dozen indigenous languages of Guatemala are just as distinct from one another as are Spanish, French, and Italian. So show them some respect. Call them languages, not dialects.
Let’s end part one of this series with an unusual bit of radio history. Aeronautical beacons are stations that broadcast a short morse code identifier over and over. Pilots use them for direction finding in lining up with the runway during bad weather. Today these are only found in the longwave band but there used to be a handful of Latin American beacons on frequencies just above the old top of the medium wave band. One of those was RAB on 1613 kHz at Rabinal, about 45 kilometers south of Cobán. It used to be an easy catch all over North America, but here’s a recording I made of it in nearby Honduras.
Beacon RAB, 1613 kHz, as heard in Santa Bárbara, Honduras, on 12 November 1982 at 0508 UTC:

Don’s DX traveling stories can be found in his book Tales of a Vagabond DXer.
I’ve been a real jack-of-all-trades in my over five decades of DXing. I began with SWBC (shortwave broadcast) but soon branched out to medium wave and voice utility. Later I added longwave beacons and more recently I’ve gotten into digital utility stations. My goal has always been to log lots of different stations from lots of different places. And the rarer they are, the better.
For SWBC and medium wave stations, as well as scheduled utility broadcasts such as marine and aeronautical weather reports, the DXing process is simple. You tune to a frequency at a time when a station is scheduled to be on the air. It’s either there or it’s not there. If it’s not there then maybe propagation isn’t right or maybe your antenna/receiver setup isn’t the best for that frequency band or the station’s power level. You tune away to find something else with plans to try again another day.
But it’s not always that easy. Most utility stations do not have fixed schedules and only come on as needed. The best example of that is two-way marine, aeronautical, and military voice communications.
In eastern North America, tune to 8906 kHz anytime from late afternoon until morning and set your receiver to USB mode. You’ll probably hear empty static at first but it’s unlikely that more than ten or fifteen minutes will pass before you’ve heard some aeronautical traffic. The frequency is assigned for communication on the North Atlantic and is heavily used by aircraft communicating with New York Radio, Gander Radio (Newfoundland, Canada), and Shanwick Radio (Shannon, Ireland). If you keep listening, the frequency will probably be occupied around 25% of the time. Wherever you are in the world, there are a few heavily used air frequencies like 8906 kHz and listening to them can be fascinating. But I want to log more than just a few easily heard stations.
Sticking to aeronautical DX, there are many assigned frequencies for different regions and air routes around the world. But propagation to those distant areas is unpredictable and less-used routes have fewer flights. Fewer flights mean less radio communication and more empty static. The most interesting frequencies may only see traffic a few times a week.
Hearing the rarest voice utility DX requires listening to lots of empty static just to get a brief DX catch. For years my process was simple. I would set my receiver to an interesting frequency and leave the tape recorder running while I sat nearby listening and doing something productive. I got some very good DX over the years that way. But I don’t want to think about how many long hours of empty static I listened to in order to get that DX.
SDRs offered some improvement. Instead of audibly monitoring a specific frequency I could now make a spectrum recording that included a band of interest, say the 8815 to 9040 aeronautical band. During playback I could visually monitor the SDR waterfall for interesting signals. That works. But watching an SDR waterfall scroll by for three or four hours gets tedious quickly.
(When I refer to SDRs, I mean ones consisting of a small box that is connected to and controlled from a computer using a software program. None of this applies to models such as the Malachite line or the Icom IC-R8600, which use SDR technology inside but mostly function as a traditional receiver.)
That better way is, I think, one of the most exciting DX tools out there – the Data File Analyzer in the SDR-Console program. Since I learned about it a few years ago, the Analyzer has gotten me all kinds of catches that I probably wouldn’t have gotten otherwise. Let’s start with an overview and then dig into the how-to.
SDR-Console is one of the better-known SDR programs and it works well with most of the common SDR radios on the market, including the Airspy, Elad, Perseus, and SDR-Play models. Here’s what the main window looks like:
The Data File Analyzer is a second window that produces a scrollable waterfall display for the entire length of an SDR spectrum recording. The display is similar to a standard waterfall with frequencies along the bottom and times along the side. However, there is also a scroll bar on the right side for browsing through the entire length of the recording. Instead of watching a four-hour spectrum recording slowly roll by in real time, I can scroll through the window looking for DX.
And this is what makes the Data Analyzer really useful. When I spot an interesting signal, I click on it and that causes the main window to start playing at that time and frequency. Now going through a four-hour spectrum recording takes from a few minutes to around half an hour, depending on how much DX I find.
Here’s a closeup of part of that same screen of spectrum recording made on 24 October 2024 at a DXpedition in western Pennsylvania, USA.
“A” marks a short exchange between an aircraft and Ndjamena Radio in Chad on 8894 kHz. “B” is Niamey Radio in Niger on 8903 kHz. “C” is Gander Radio on 8891 kHz. Just to the left of that is a string of digital signals. “D” is New York Radio on 8918 kHz. Again, there is a string of digital signals just to the left. Finally, “E” is communication from Dakar Radio in Senegal and Sal Radio in the Cape Verde Islands on 8861 kHz. I caught four African aero stations in just four-and-a-half minutes. I could also show you long stretches of time when there was nothing interesting coming in. With the Data File Analyzer I was able to visually find and focus on the DX and not waste my time with the empty static.
Here’s another image taken at the same DXpedition. Notice the three transmissions between 8820 to 8845 that seem to be mirroring one other.
That turned out to be Flightwatch Brisbane, the Australian regional aeronautical network. It uses multiple transmitter sites on 8822, 8831, and 8843 kHz to cover the entire country. I had never logged it before and I doubt I would have found it if DXing in the traditional manner.
Here I’m going to assume that you already have SDR-Console installed and know the basics of how to use it, including making spectrum recordings. (If not, see the links at the end.) This article was written using version 3.4 of SDR-Console. Some of the functionalities described are not in earlier versions, so upgrade if you are not up to date. And I should point out that while you can do this on a single monitor, it works more smoothly if you have a dual monitor setup and can put each window on a different screen. Continue reading

An internet search revealed the following;
Part 15 of the Federal Communications Commission (FCC) rules allows some low-powered radio devices to operate without a license on the AM and FM radio broadcast bands. These devices are subject to certain restrictions, including:
Some examples of Part 15 radio stations include:
Often used by hobbyists, drive-in theaters, or on college or high school campuses.
These transmitters air a repeating loop of information, such as traffic or highway construction. They typically operate on empty channels on the AM broadcast band.
A custom product that can include special audio systems, USB / internet connectivity, cabinets, and antenna mounting styles.
Educational institutions can use a transmitter without a license if the signal coverage is limited to their property.
1610 kHz with low power, usually around 10 watts, such as the one I hear near the Blue Water Bridge between Sarnia, Ontario and Port Huron, Michigan
Over a quarter century ago, these frequencies began to be used in the U.S. by BCB stations. I still have recordings of a half dozen of these from the early days.

More of Don’s traveling DX stories can be found in his book Tales of a Vagabond DXer.
For DXers of Latin American stations, the period from about 1978-1998 was the golden age of DXing Peru. Those years saw an explosion of shortwave broadcasting from small towns, especially in northern Peru. Most of the stations were unlicensed and few lasted long. I tell the complete story of the period in Tales of a Vagabond DXer. However, the book doesn’t have many pictures as that would have made it much more expensive to produce and to buy. Fortunately, this blog is a perfect place to share photographs.
In those days one of the biggest radio hotspots in Peru was the department of Cajamarca. Over one hundred stations broadcast on shortwave, however briefly, just from that department. Cajamarca is a special place to me because I visited the region in 1985 during the height of the radio boom and visited over a dozen stations in the towns of Chota, Bambamarca, Cutervo and Celendín and the city of Cajamarca.
Chota is the largest town in the central part of Cajamarca department and played an important role in the development of broadcasting in small provincial towns. It’s about 140 kilometers north of Cajamarca but in between is cold barren Andean altiplano rising to over 4,000 meters elevation. In 1985 the bus ride took twelve hours and we encountered ice storms coming and going.
In 1985 Chota was a sleepy Andean town in a fertile river valley.
Radio Chota was already seven years old when I visited in March 1985. The station only had a medium wave license but also broadcast unlicensed on the out-of-band shortwave frequency of 6296 kHz where it was widely heard by DXers. Later they received a shortwave license and were assigned 4890 kHz but several years passed before they actually switched frequencies. Radio Chota was a success story and is still on the air today. Most of the stations I visited in 1985 were not so lucky.
QSL collection of Don Moore … www.DonMooreDXer.com …
Radio Chota as heard on 6296 kHz in 1982 via On the Shortwaves:
Radio Chota as I heard it in Quito, Ecuador on 4890 kHz in 1997:
Radio Acunta was a more typical broadcaster of the period. The station broadcast irregularly in 1984 and 1985 with a homemade 100-watt transmitter. The station didn’t survive but the transmitter with its crystal-controlled frequency of 5800 kHz was a good starter set. Over the next several years DXers followed its movements around northern Peru as it was sold from one would-be station to another.
This picture with the homemade posterboard signs really captures the transient nature of broadcasting in rural Peru in the 1980s. Radio San Juan de Chota was on 5274 kHz for a few months in late 1984 and early 1985. I doubt they ever had permanent signs made. They did, however, have professionally printed envelopes.
Recording of Radio San Juan de Chota via On the Shortwaves:
Bambamarca is a smaller farming town 20 kilometers south of Chota. It was also home to several shortwave stations over the years. Radio Bambamarca had a short appearance on 5657 kHz in the mid-1980s.
I always expected to return to the Cajamarca area someday. Finally, in November and December 2017, I revisited all the places I had seen in 1985 and more while researching my historical travelogue Following Ghosts in Northern Peru. A few months later, in May 2018, I returned to the city of Cajamarca and Chota with my DX travel buddies, John Fisher and Karl Forth. Continue reading
