Many thanks to SWLing Post contributor Dan Greenall, who shares the following guest post and asks, “Wonder who can add to this list?“:


A Look Back – DXing between 1610 and 1700 kHz

by Dan Greenall

1. The Caribbean Beacon, Anguilla West Indies 1610 kHz (1985 QSL)

2. NDB stations (non-directional beacons)

  • transmitted call letters on CW, mostly from airports, heard in the 1970’s
  • examples: MDE Medellin, Colombia 1690 kHz and RAB Rabinal, Guatemala 1613 kHz

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:

  • Range: On FM frequencies, the effective service range is limited to about 200 feet (61 meters).
  • Field strength: The field strength should not exceed 250 ?V/m (48db) at 3 meters.
  • Detachable antennas: Part 15 rules prohibit detachable antennas on all Part 15 transmitters.

Some examples of Part 15 radio stations include:

  • Microbroadcasting

Often used by hobbyists, drive-in theaters, or on college or high school campuses.

  • Talking roadsigns, talking houses, or talking billboards

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.

  • InfOspot

A custom product that can include special audio systems, USB / internet connectivity, cabinets, and antenna mounting styles.

  • Free-radiate AM radio stations

Educational institutions can use a transmitter without a license if the signal coverage is limited to their property.

5. TIS (Travellers Information Stations)

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

6. Expanded AM broadcast band 

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.

Don Moore’s Photo Album: Albania – Part One

Finding Radio Tirana

More of Don’s traveling DX stories can be found in his book Tales of a Vagabond DXer [SWLing Post affiliate link]. Don visited Albania in March 2024. 

Of all the places that I’ve been to but wouldn’t have imagined visiting forty years ago, Albania is definitely at the top of the list. Yet here I am wandering around in Tirana’s coolest and most trendy neighborhood. I walk by an Argentine steak house, several Italian trattorias, a Texas cowboy-themed hamburger restaurant, and several sports bars with huge TVs tuned to football games (or soccer if you prefer). Boutique hotels, fashionable clothing stores, and shiny office buildings complete the scene. It’s just another upscale neighborhood in the global village. And it’s in Albania.

I hadn’t planned on getting an afternoon drink until the Radio Bar Tirana popped up on Google Maps. How could I not stop by a place with a name like that? The shelves behind the bar are filled with bottles of imported gin, whisky, tequila, and cognac, but I order a glass of raki, Albania’s version of the cheap firewater that every culture seems to have. It’s strong and burns my throat. No wonder Albanians have survived all that they have been through over the past six centuries. You have to be tough and resilient to drink this stuff. Or maybe it’s drinking raki that made Albanians tough and resilient.

The bar is staffed by two hipsters. I tell them about how decades ago (long before they were born) I used to listen to Radio Tirana on shortwave in the United States. They had never heard of Radio Tirana’s shortwave broadcasts and were amazed to know it was heard in the United States. I think they were also amazed that someone from outside Albania would have wanted to listen to the station during those terrible times. The bar, they explain, has nothing to do with any radio station but takes its name from the many old radios that line the walls. And it’s clear that I fit in better with the dusty wall décor than with the young bartenders or the chic patrons.

The back of the bar opens onto a large, covered patio filled with Albania’s version of smartly dressed young professionals. Late afternoon is the time to drink and to network. But the day is warm and sunny and no one wants to be inside. The main room is empty except for the bartenders and a man in the corner trying to work on his laptop despite the loud voices coming from the patio. I have the inside to myself so I wander around sipping raki, taking pictures of old radios, and remembering Radio Tirana.

The Kantata M model radio was produced in Murom, Russia by the Murom RIP Works in the 1970s.

The Red Lantern Model 269 was made in Shanghai in the 1960s. It predates the General Electric Super Radio by at least fifteen years so the “2 Band Super” name was not a takeoff on the popular GE receiver.

History in a Nutshell

Yesterday, I had visited the vast National History Museum on Skanderbeg Square in the heart of Tirana. All the peoples of the Balkans had a golden age and for Albanians it was the mid-1400s. The Ottoman Empire was the strongest and most aggressive power in the region but George Skanderbeg and his successors held off the Turks for fifty years. The Turks eventually conquered Albania and much of the Balkans but the delay likely prevented them from taking even more of Europe including Italy.

The Ottomans would rule Albania for over four centuries and in that time most Albanians converted to Islam. It was the only Ottoman territory in Europe where that happened. But Albanians continued to remember Skanderbeg, the Catholic who had led the fight against the Muslim Turks, as their national hero. And they never took their Islam as seriously as most other places. That’s why they still drink alcoholic raki.

Over the centuries, the Albanians would periodically raise the double-headed eagle flag of Skanderbeg and rebel against Ottoman rule. And each time the rebellion would be brutally put down. But by the early 20th century the Ottoman Empire had been significantly weakened and Greece, Serbia, and Bulgaria had already won their freedom. In 1912 those countries went to war against the Ottomans to gain more land for themselves and as a side result Albania gained its independence. Then two years later World War I came and Albania and its neighbors were overrun by the Austro-Hungarian Empire.

When a war is over the victors usually divide the spoils and World War I was no different. Secret negotiations among the European powers included a plan to divide Albania between the new nation of Yugoslavia, Greece, and Italy. When the plans leaked out Albanians once again raised the double-headed eagle flag in defiance and this time received support from the United States. The Woodrow Wilson administration made sure that Albania would continue to exist with its pre-war borders intact.

Still, Albania’s bigger neighbors, especially Benito Mussolini’s Italy, continued to intervene in the country’s affairs. In 1928, at Mussolini’s urging, Prime Minister Ahmed Zogi declared Albania a monarchy and crowned himself as King Zog I. As the years passed King Zog came to realize that Mussolini’s plans for Albania were not friendly and he gradually distanced his government from the Italian ruler. The unmarried king also knew that his dynasty needed an heir. In April 1938, 42-year-old King Zog (a Muslim) married 23-year-old Countess Geraldine Apponyi de Nagy-Appony, a Catholic and daughter of a Hungarian nobleman and his American wife.

Meanwhile Albania was slowly entering the modern world and that included radio broadcasting. In 1937, a new radio-telephone station was installed outside of Tirana. The three-kilowatt shortwave transmitter was also used to broadcast several hours of programming per day, but it wasn’t a formal radio station. In the early 1930s several four-story Italian style villas had been built along Kont Urani Street, not far from Skanderbeg Square. In 1938, King Zog’s government confiscated one of the buildings, the Italian-Albanian Culture Center, and made it the first home of Radio Tirana. The new station was officially inaugurated by King Zog and Queen Geraldine in a live ceremony on 28 November 1938. A few months later, on 5 April 1939, the station had its first news scoop when it announced the birth of Crown Prince Leka to the world.

The prince’s birth was good news for Albania, but it was a dark time in Europe. Just a few weeks earlier Adolf Hitler’s Nazi army had marched into Czechoslovakia without consequences. Not to be outdone by his German counterpart, on 7 April (two days after the prince’s birth), Mussolini invaded Albania. The Italian plans had been drawn up quickly and haphazardly and would likely have failed against a formidable opponent. But the handful of patrol boats in Albania’s navy could do nothing to stop the two battleships, six cruisers, nine destroyers, and numerous smaller ships that carried the invasion force across the Strait of Otranto. And Albania’s tiny poorly trained army was no match for the 100,000 troops that came ashore. In just a few days Albania had been overrun and King Zog and his family had fled to Greece (and eventually to England).

What happened over the next few years is a complex story. Mussolini’s goal was to turn Albania into an Italian client-state. The invaders set about to Italianize the country while also benefiting from its resources and workforce. As Radio Tirana was a key part of that process, the Italians modernized the studios, installed new antennas and transmitters throughout the country, and professionalized the programming. In order to not alienate the population, the station tried to maintain a balance between promoting Italian culture while also carrying Albanian culture and music.

Meanwhile, a resistance run by loyalists to King Zog fought back. They had some initial successes but soon the Italians quashed the movement by killing or capturing most of its leadership. They hadn’t made much effort to hide what they were doing. That should have ended the resistance but a new force, Albania’s tiny Communist Party, stepped in to fill the leadership vacuum. Unlike King Zog’s men, they already knew how to operate an underground movement. Gradually the Communists formed an effective guerilla force in Albania’s mountainous interior.

Italy’s surrender to the Allies in September 1943, should have been good news for Albania but the Nazis quickly sent in troops to take over and prevent the Allies from moving in. Their rule was more brutal than anything the Italians had done and that pushed more Albanians to join the resistance. By October 1944 the movement had grown to the point that its leaders had the confidence to launch an all-out attack on Tirana. For three weeks fighting raged back-and-forth in the city streets until on 17 November the last German troops withdrew under the cover of darkness. Tirana was once again ruled by Albanians and one of the leaders was a man named Enver Hoxha.

Enver’s Place

My glass of raki is empty and I have all the pictures I want. I hand a generous tip to one of the bartenders. He was kind enough to move some bottles so I could get a clear picture of the “Radio Bar” sign. I continue up the street in the direction I had been heading and a block later come to my next destination, the house where Enver Hoxha lived while he ruled Albania.

The house doesn’t look at all like the sort of place a national ruler would live, let alone one who ruled with a deadly iron fist. It’s more like the kind of Frank Lloyd Wright inspired house that might be found in an upscale American suburb. Next door is the Abraham Lincoln Center, a school that teaches American English to Albanians. It’s a good thing, I think, that Enver Hoxha is dead. Enver hated the United States and he would never have been happy with these neighbors.

Unfortunately, the house is not open for tours so all I can do is stand outside and take pictures. As I look at the house I think back again to Radio Tirana. I hadn’t planned to visit any radio stations on this trip but the raki is still having its effect on me. Just for fun, I open up Google Maps and type in Radio Tirana. Surprisingly, I get a result and it’s only two blocks further down the same street. But the huge Radio Televizioni Shqiptar building on the corner with Rue Ismail Quemal turns out not to be the Radio Tirana building I had seen in the old picture in the national museum.

Inside, two young women are working at the reception desk and one speaks excellent English. I explain how I used to listen to Radio Tirana on shortwave. Unlike the bartenders, she knows all about it even though she is clearly in her early 20s. She says that in those days Radio Tirana would have been broadcasting from the old building near Skanderbeg Square. I’m about to leave but then I turn around. “Does that old building still exist? I would really like to see it if it does.” Continue reading

Bob asks: “What’s Your Favorite Corner of the Dial?”

Many thanks to SWLing Post contributor, Bob Colegrove, who shares the following guest post:


What’s Your Favorite Corner of the Dial?

As asked by Bob Colegrove

Let’s suppose you’ve been listening to radio for a while.  Consciously or not, you’ve probably favored a range of AM, SW, or FM frequencies.  These are areas where you go to DX or just listen to your favorite stations.  One area I seem to keep returning to is the very bottom of the medium wave band, roughly 530 kHz to 600 kHz.  With the convenience of today’s digital radios, I have consciously pushed the envelope somewhat lower.

The main reason for specializing in that frequency range is the challenge.  In the very beginning there didn’t seem to be much at the extreme lower end of the AM broadcast band.  Growing up in Indianapolis in the ‘50s, the local stations were all at the upper end of the mediumwave dial.  WXLW held down 950 kHz – lower than that nothing.  I would say the stator plates on the variable capacitor got very dusty, never being closed any further than that on many radios.

Another challenge was sensitivity.  In analog times, the sensitivity of a tuned circuit had some falloff as the inductance/capacitance (L/C) ratio decreased.  Sensitivity is highest with the variable cap open at the high end of the band.  As you tune lower by increasing capacitance (inductance remaining constant), the Q and consequently sensitivity drop off – not dramatically, but somewhat.

Finally, not all old analog radios tuned to 530 kHz; some were even challenged to tune 540 kHz.  By performing a little mischief with the alignment, I could sometimes venture into unknown territory.

This was all part of the challenge.  So, what could I do to coax some activity out of the bottom of the band?  I spent many hours poring over Bill Orr’s Better Shortwave Reception (Radio Publications, Inc., Wilton, CT, First Edition, 1957) and tweaking caps and coils trying to squeeze the last few kilohertz and microvolts out of my radios.  This exercise fascinated me and became a hobby within a hobby.  If I may be allowed a self-deprecating aside here, the first time I took a radio out of the cabinet, I just assumed that all these alignment screws were loose, and dutifully torqued them down.  The alignment problem is not comparatively complex with today’s digital receivers.  Note, I didn’t say it was unimportant.

I still tend to favor the bottom of the medium wave band.  Below is a list of my catches over the past couple of years.  It’s just a sample of what one might hear by casual listening over time.  Highlighted stations are heard during daylight hours.  This is NOT intended to impress anyone, rather it is hopefully a stimulus for your own efforts.

As another attraction of the lower mediumwave band, you will find a potpourri of stations.  Besides regular North American broadcasting stations, one might possibly hear an occasional high-powered trans-Atlantic station which is not synchronized with the 10 kHz spacing.  530 kHz is interesting.  It is not used in the US by commercial broadcast stations.  Instead, stations from Canada and Cuba at roughly orthogonal directions from me are regularly audible at night on this frequency.  Thus, the radio is tuned by simply rotating the antenna.  530 kHz is also home to several Travelers’ Information Stations (TIS) throughout the country.  Question:  How will this long-time service fare if travelers don’t have AM radios in their new cars?  Finally, the very bottom of the frequency range still contains a few holdouts of non-directional beacons.

Frequencies below 530 kHz probably put a strain on the medium wave bands of old radios, but they are likely no problem on most digital radios having both LW and MW coverage.  As mentioned, there are a few non-directional beacons down there.  They are Morse coded using amplitude modulation.  I have found placing the receiver in SSB mode makes detection much easier, as the heterodyne from the carrier can be heard well before the signal is strong enough to produce any audio.  These beacons generally fade in for brief periods of time and then fade out like passing comets.

My most recent catch was experimental station WI2XLQ, 486 kHz, during its annual Fessenden Event on Christmas Day and again on New Year’s Day.  See https://swling.com/blog/?s=Fessenden+ .  The experience was not the armchair listening quality one might expect from FM or the Internet.  Instead, it was weak and fraught with atmospheric noise.  The station came in periodically, then disappeared, in short, DXing to its highest degree of satisfaction.

The antenna is the key to good reception, and there is no exception to this rule at the lower end of the AM band.  Many years ago, I switched to an indoor, resonant loop antenna.  The selectivity, directional properties, and noise rejection of a loop antenna in this frequency range are superb.  The figure below shows my 40-year-old loop antenna, which is still used in its original form.  It tunes from ~485 kHz through ~1710 kHz in two bands.  The antenna can rotate 360 degrees horizontally and 90 degrees vertically.  Further, it is mechanically balanced to remain in any position without locking.  For those not inclined to construction projects, the Tecsun AN-100, AN-200, and Terk Advantage will perform quite well through inductive coupling with a portable radio’s ferrite bar antenna.

As all experienced medium wave DXers know, for success you need to have patience, “set a spell,” and let the radio do its thing.  Radios are living organisms, kind of like cats, very independent at times, and will let you hear only what they want you to hear.  On many channels, stations will come and go over time.  If you’re lucky, you might catch an ID; lacking that, you might be able to identify it by the format or network.  You might try to compare the contents you hear on the radio with what you can hear online either over the station’s website or via streaming sites such as TuneIn, iHeart, or Radio Garden.  There may be a delay between the Internet stream and the live signal.

When you feel you’ve exhausted the possibilities, there’s still more.  Turn the antenna 90 degrees and start over.  You’re only half finished with that frequency.  Don’t forget a headset or earbuds.

What’s the next challenging rung on the limbo bar?  Well, possibly the 633-meter ham band, 472 to 479 kHz.  I’ll have to pad the old loop with a small capacitor to tune down there.

What’s your favorite corner of the dial?  Why?

Clear Channel Stations: Dan’s gateway into the world of DXing

Many thanks to Dan Greenall, one of our dedicated Shortwave Radio Audio Archive contributors, who shares the following guest post:


Clear channel BCB stations – My Introduction to the world of DXing

by Dan Greenall

Sometime in the mid 1960’s, I acquired a Japanese made AM only transistor radio similar to the one pictured.

I was entering my teenage years and living in southern Ontario, Canada in relative proximity to the U.S. border, and was immediately fascinated that I could receive American stations from places such as Buffalo and Rochester NY as well as Detroit MI with amazing clarity.

Before long, I discovered that signals from much further afield would begin to come through at dusk and throughout the night time hours. Although I was unaware at the time, many of these would be from so-called “clear channel” stations, those operating on frequencies with the highest level of protection from interference from other stations.

In addition, many of these stations ran a full 50 kw of power.  Signals from the Atlantic seaboard to the Midwest could often be heard at near local strength if I turned my radio to just the right angle.  At this point, I was beginning to learn about the directional properties of the built-in ferrite rod antenna.  It gave me great pleasure to be able to listen to their local ads, newscasts, or a far away sporting event from the comfort of my home.

I recall listening regularly to WOWO in Fort Wayne IN on 1190 for their play by play announcements of the Fort Wayne Komets hockey games.  Then there was a station identifying as WFAA in Dallas.  That was back when they shared 820 kHz with WBAP whose famous cowbell you can hear in one of the audio clips below.

By the end of 1969, a friend of mine had encouraged me to try shortwave, and I “borrowed” my parents Philips kitchen radio for a few months, but that is another story. I wonder how many others got “hooked” in this manner?

A few brief recordings of clear channel stations that I made in the early 1970’s are presented here. Many, but not all, of the stations heard in the last two links are from clear channel stations. Reception for these recordings was made using a Realistic DX150A or a Hallicrafters S-52 receiver hooked up to an outdoor long wire antenna.

As a sidebar, the National Radio Club has put out a number of books showing the daytime/nighttime directional antenna patterns of AM broadcasting stations in the USA and Canada.

I gave up my copy from 1973 a number of years ago, but you can find this one and others online. I found this very useful.

For example, it is easy to see why I was more likely to hear WBT Charlotte NC on 1110 kHz from my listening post in southern Ontario, Canada, rather than KFAB Omaha, NE.

Guest Post: Pre-Internet Sources of Shortwave Information

Many thanks to SWLing Post contributor, Dan Greenall, who shares the following guest post:


Sources of SWL Information “Pre-Internet”

by Dan Greenall

When I first discovered the world of shortwave listening, many years before the internet, access to hobby related information was mostly available through over-the-air DX programs, monthly DX club bulletins, as well as a number of books and electronics magazines.  I joined a few clubs including the Midwest DX Club, SPEEDX, and the Ontario DX Association, and eagerly awaited each issue of Electronics Illustrated and Popular Electronics (early 1970’s) on the news stand.  Later, in the 1980’s,  Popular Communications and Monitoring Times came along, though these were not always easy to find here in Canada.

 

Ironically, nearly all issues of these magazines can be read today, over 30, 40 and even 50 years later, thanks to David Gleason’s not-for-profit, free online library

https://www.worldradiohistory.com/index.htm

You can also find the semi-annual (and eventually annual) Communications World (1971-81) which contained the popular White’s Radio Log.

As well, five issues of the Communications Handbook can be found;  1963, 1966, 1967, 1974 and 1977.  It only came out once a year but was still a favourite of mine, so much so, that I still have my copies from 1971 and 1972.

I have scanned parts of these and put them on the Internet Archive.  You can find them here:

Communications Handbook 1971: https://archive.org/details/page-09

Communications Handbook 1972: https://archive.org/details/page-20

Here are links that will lead to some of the other magazines:

As a bonus, all of the issues of the monthly SPEEDX bulletin (1971-95) have been made available here

https://www.worldradiohistory.com/Speedx.htm

And finally, a good read is Shortwave Voices of the World by the late Dr. Richard E. Wood written in 1969.  I still have my copy of it, but you can find it online here

WDX SWL registration program

My link to the 1971 Communications Handbook contains pages regarding the old WDX SWL registration program. I have found my old certificate from December 1971:

Wonder how many others still have theirs, or even the WPE ones from the 1960’s?
