More of Don’s traveling DX stories can be found in his book Tales of a Vagabond DXer. Don visited Albania in March 2024.

Albania has a lot to offer foreign visitors. The country has coastal beaches, beautiful mountains and historical sites hundreds and thousands of years old. Tirana is a fascinating city filled with good restaurants and friendly people. It’s inexpensive. The central city is easy to get around on foot. I’m already planning my next visit.

But the number one reason to visit Albania is to see the sites related to the Communist era and the Enver Hoxha dictatorship. I don’t think there is anywhere else where you can get such close insight into what real life was like inside a brutal police state. Indeed, after visiting Tirana, I can’t imagine how anyone could praise dictatorships or say that their own country would be better off under a dictatorship. In Tirana three sites in particular stand out in this regard. And each of them has some interesting displays involving the use of radio.

The House of Leaves

The House of Leaves … the name sounds peaceful and innocent. That was once true. Constructed in 1931, the two-story villa originally served as the first obstetrics clinic in Albania. Then when the Nazis moved in after the Italian surrender in 1943, it was chosen as headquarters for the Gestapo. That might have been a minor blip in the structure’s history, but the Gestapo had remade the building into just what Enver Hoxha’s new government needed: a headquarters for their secret police.

The dreaded Sigurimi would occupy the building for nearly five decades. But that was supposed to be a secret, so no one could say what the villa really was, even though everyone knew. So it became known as The House of Leaves from the vines that covered the outer walls. Even then, the name was mostly whispered among the closest friends. It wasn’t safe to pay much attention to the building.

After the Communist regime fell in 1991, The House of Leaves mostly sat unused. Then, in 2014 the Albanian Ministry of Culture announced it would be turned into a museum telling the story of Sigurimi and its operations. The Museum of Secret Surveillance opened in 2017 and three years later was awarded the European Museum of the Year award by the Council of Europe.

The museum has many rooms focusing on various aspects of Sigurimi’s work. My favorite was one filled with electronics used to monitor and record conversations by suspected malcontents.

The key to monitoring someone was placing a radio transmitter bug in the suspect’s home. The Sigurimi made their own bugs in a workshop in The House of Leaves. They were particularly proud of the tiniest ones, which could very easily be hidden.

The bugs were usually placed inside a small piece of wood that could be placed under a table or chair. The effective range was only about two hundred meters, so monitoring posts had to be in the same building or nearby. The Sigurimi would either recruit a neighbor or persuade a neighbor to host a Sigurimi agent to monitor the recordings. Rinia brand transistor radios made in Romania were the preferred receiver. They were inexpensive and could easily be modified to receive the desired frequency. And they were common enough that possession of one didn’t mark a person as a government agent. Agents usually listened in on headphones while also making a recording of the conversation.

In some cases, homemade amplifiers were used to boost the weak signals produced by the tiny bugs.

Recordings of conversations of interest were taken back to The House of Leaves for further investigation at monitoring posts such as this one.

The Bunkers

Enver Hoxha knew that tiny Albania could never support an army large enough to repel an outside invasion. His experience as a guerilla in World War II, on the other hand, had convinced him that an armed hostile populace could do the job. Albania was, after all, the only occupied country to retake its own capital without any outside help. So Hoxha based Albania’s national defense on making sure that invading the country would be so difficult and painful that no one would dare attempt it.

A key part of that policy was constructing concrete bunkers. Hoxha’s goal was to construct 750,000 of them – approximately one for every four Albanians at the time. Just how many were actually constructed is not known, but the number was in the hundreds of thousands. And they were built everywhere – in farms, in forests, in villages, and in cities.

Most were the three-meter-wide Qender Zjarri type, just large enough to give two or three combatants a concealed firing position. Depending on the location these were built individually or else in small clusters. Today, a fun activity while traveling by bus through Albania is seeing how many you can spot. Occasionally these bunkers are used for storage but there are so many that most are abandoned other than the occasional visit by local teenagers. Evidently, they’re the cool place for losing one’s virginity.

The second type of bunker was the eight-meter-wide Pike Zjarri, intended to serve as local command centers. Being larger, many of these have been put to other uses. And then there were the big bunkers, huge complexes of underground rooms and tunnels where officials would take refuge and continue to run Albania’s government. But today’s Albania is not concerned with repelling foreign invaders. Instead it welcomes them in the form of tourists. And so two of the biggest bunker complexes in Tirana have been turned into museums. And both of them contain some interesting radio memorabilia.

Enver’s Refuge

The biggest bunker was a vast underground complex built in the 1970s inside the base of a mountain on the eastern outskirts of Tirana. Construction was so secret that this bunker’s existence wasn’t even known publicly until the 1990s. This was where Enver Hoxha and other top officials would have gone in the event of an invasion or nuclear attack. It had over one hundred rooms on five levels with its own power and water systems. The entrance passed through a decontamination station where anyone entering could wash off the fallout if a nuclear bomb had already been dropped. (Or so they hoped.)

The inside is a labyrinth of hallways and small rooms used for everything from communication centers to support services. There is even a small auditorium where the Albanian legislature could meet. Enver Hoxha and the prime minister had small spartan private apartments. Other officials, guards, technicians, and servants slept in dormitories. Of course, the facility was never used. It’s believed that Enver Hoxha only visited three times – once when it was completed in 1978 and then two more times for drills.

One of many hallways in the Enver Hoxha’s refuge.

The Albanian military continued to use the facility for several years after the Communist government fell in 1991. After that it was locked up. Then in 2014 a pair of journalists came up with the idea of making it into a museum which was named Bunk Art. But it’s a history museum, not an art museum. Some rooms were left unchanged to show the structure’s original purpose. Others were filled with exhibits on Albanian history, the Italian invasion, the Communist period, and life under Communism. And those exhibits include a few interesting radio items.

According to the display, this was one of two portable transceivers in possession of Xhevdet Mustafa when he was killed by the Sigurimi on the beach south of Tirana in 1982. The display didn’t make clear who Mustafa was working for.

On several occasions in the early 1950s the CIA tried to insert small bands of Albanian agents into the country, mostly without success. This Russian-made transceiver was part of the gear that came with a small group of agents parachuted into Albania in 1953. The group were all killed or captured when they landed. With help coerced from the prisoners, the Sigurimi used this radio for several months to trick the CIA into continuing to air-drop supplies into the mountains.

This black-and-white Albanian-made TV was configured at the factory to only receive Albanian channels. However, clever Albanians figured out ways to use small electronic circuits (called kanoce) that overrode those limits. Albanians along the coast were able to receive TV from Italy while those in border areas could receive Yugoslav or Greek TV.

The Downtown Bunker

The original Bunk Art proved so popular with Albanians and foreign visitors that in 2016 it was renamed Bunk Art 1 and a second location, Bunk Art 2, was opened in the city center. This bunker had been built under the city streets near The House of Leaves and had been intended for use by the Ministry of Internal Affairs. It consisted of a single level with several branching hallways lined with small rooms. Today, it’s a museum telling the story of the Ministry (of which the Sigurimi was just one part) until its dissolution in 1991.

This bunker was also configured for a long-term stay. The Minister of Internal Affairs had this private bedroom.

The Broom Bug

On 12 December 1985, the streets of Tirana were crowded with people out to watch a large patriotic parade which just happened to pass by the Italian embassy. Two women and four men dressed in fashionable western clothes and chatting in Italian among themselves snaked their way through the crowd to the door of the embassy. The Albanian police monitoring the door didn’t try to stop them. Obviously, they were Italian tourists or embassy workers. Except they weren’t. The sisters and brothers of the Popa family had long been persecuted by the Albanian government as their parents had collaborated with the Italians during the war. And now the six children wanted political asylum.

The Italians were willing to resettle the family in Italy but the Albanian government refused to give them permission to leave. Instead Albania demanded that the siblings be turned over to its police, which the Italians refused to do. The family would live in the embassy for 4 ½ years until the Albanian government finally agreed to let them go. In the meantime the Albanians kept a strong police and military presence in the neighborhood surrounding the embassy.

The Sigurimi wanted to know what was going on inside so they recruited an Albanian maid who worked at the embassy to help them. She was given five bugs and instructions to hide them in the usual places like behind paintings and under tables. They knew the Italians would find these and that was fine. It would give the Italians false confidence that they had found all the bugs. The real bug was concealed in a special new broom that the maid brought in and left in a closet next to where the Popa siblings stayed. Each day she was given a freshly charged battery to swap with the depleted one inside the broom. The Italians never discovered the bug-in-a-broom. The Popa siblings were finally allowed to leave the embassy for Italy on 3 May 1990.

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

The police promptly responded to the call, but the SBU for some reason delays its response to illegal actions People’s deputy Mykola Knyazhytskyi announced this on Facebook .

“In Lviv, journalist Vitaly Portnikov, who hosts programs on Espresso and Radio Svoboda, found a eavesdropping device at home. It is a voice recorder with the ability to record for a long time. The police were called. They arrived quickly. The SBU was called. They are not going. As a member of the Verkhovna Rada, I ask the SBU to come immediately and disrupt case. We don’t know who installed this device and for what purpose: our services, foreign services or criminality,” the politician said.

Vitaly Portnikov commented on the incident for “Espresso”:

“Today, while cleaning the apartment I lived in at the end of February, when the war started, I found a recording device under the bed. The device had an inventory number. I informed the law enforcement authorities about my discovery so that they could investigate this incident.”

The journalist added that he hoped for a high-quality investigation and clarification of all the circumstances of the case:

“After my statement, the investigators of the SBU of the Lviv region conducted an inspection of the premises and seized a device that is a device for listening and recording information. I hope that the relevant structures will conduct an examination and find out by whom and why this device was placed in my apartment.”

Opinion: The Future of AM Radio
England, Scotland, Wales and Northern Ireland (FrequencyFinder.co.uk)

Summary

AM radio in the British Isles is now in terminal decline with audiences dropping and many transmitters closed already. The majority of the remaining transmitters will likely close by the end of 2027. Over the next few years, the BBC and major commercial broadcasters will be looking to minimise their AM transmission costs by reducing transmission powers at the high-power sites and closing some of the low-power transmitters serving small audiences.

A coordinated AM shutdown may then follow at some point, most likely in 2027, though some independent broadcasters may continue using AM beyond this. This article explores these issues in more detail.

ITU’s ham radio station celebrates 60 years on air (ITU)

By Nick Sinanis, callsign SV3SJ, President of the International Amateur Radio Club (IARC), and Attila Matas, callsign OM1AM, Vice-president and Station Manager, IARC

Did you know that the United Nations specialized agency for information and communication technologies owns and operates its very own radio station?

Residing at the headquarters of the International Telecommunications Union (ITU), the 60-year-old amateur station operates under the callsign 4U1ITU.

It started broadcasting on 10 June 1962 and was officially inaugurated the following month by then UN Secretary-General U Thant and ITU Secretary-General Gerald Gross – himself a ‘’ham” radio enthusiast known by the personal callsign W3GG.

Recognized as a unique “country” in the ham radio community, 4U1ITU operates in accordance with privileges extended by ITU and the Government of Switzerland. It has also earned the DXCC (or ham radio “century club”) award from the American Radio Relay League (ARRL), confirming air contacts with 100 or more countries.

From its long-time home on the 5th floor of the Varembé Building in Geneva’s international district, this unique broadcasting outlet still today serves as a model for the highest standards of amateur radio station operation everywhere.

From one to a million

4U1ITU’s first contact, or “QSO” in ham radio parlance, was made with a German station called DL4VK. Further QSOs followed, amounting to over 1,300 contacts worldwide in the first 24 hours.

In the six decades since, ITU’s radio station has made over a million contacts using Morse code carrier wave (CW), voice (SSB), and digital operational modes, based on more than 20,000 two-way QSOs with radio amateurs around the world.

4U1ITU can operate on most of the frequency bands allocated to amateur and amateur-satellite services as identified in Article 5 of the Radio Regulations.

Aside from letting licensed radio amateurs in ITU, its Member State representatives, and its conference and meeting delegates contact fellow radio hams, the station promotes international goodwill and cooperation across the community. It also allows hands-on demonstrations of amateur radio communications for delegates and meeting participants. [Continue reading…]

Podcast dives into world of Cold War Numbers Stations

Many thanks to SWLing Post contributor, Ulis, who shares a link to the following episode of the Cold War Conversations podcast which focuses on numbers stations:

Cold War number stations

You might remember listening to short wave radio during the Cold War and coming across weird transmissions of metallic voices reciting random groups of numbers through the ether. These are number stations, shortwave radio stations characterised by broadcasts of formatted numbers, which were being sent to spies operating in foreign countries.

Number stations were used widely during the Cold War and we speak with Jo Reggelt of ShortwaveNumbers.com. Jo has been working with Simon Mason who was a founding member of ENIGMA, launched in the 1980’s after identifying several of these stations.

We discuss in detail the operations behind the transmissions and the stations themselves. You will hear some sample transmissions, including one of drunken Stasi officers serenading their agents after the opening of the Wall. [Continue reading…]

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


Owning a shortwave radio is once again a subversive activity (Hackaday)

An abiding memory for a teen fascinated by electronics and radio in the 1970s and 1980s is the proliferation of propaganda stations that covered the shortwave spectrum. Some of them were slightly surreal such as Albania’s Radio Tirana which would proudly inform 1980s Western Europe that every village in the country now possessed a telephone, but most stations were the more mainstream ideological gladiating of Voice of America and Radio Moscow.

It’s a long-gone era as the Cold War is a distant memory and citizens East and West get their info from the Internet, but perhaps there’s an echo of those times following the invasion of the Ukraine. With most external news agencies thrown out of Russia and their websites blocked, international broadcasters are launching new shortwave services to get the news through. Owning a shortwave radio in Russia may once again be a subversive activity. Let’s build one! [Continue reading…]

Radio’s Hardware Problem Grows (Radio Ink)

(By Ed Ryan) When was the last time your station gave away a slick looking radio as a promotion (batteries included)? How many more echo dots will radio stations keep giving away before they realize they may be pushing listeners to find something else to listen to?

In a teaser for Edison Research’s upcoming Infinite Dial presentation at Podcast Movement’s Evolutions next week, the research firm reported that the number of Americans who say they do not have a single radio in their home continues to rise.

In the 2020 Infinite Dial, performed before the onset of the COVID-19 pandemic, just under one-in-three Americans age 12 and older reported not having a single radio in their home, according to Edison. In 2022, that number is now 39%.

Fourteen years ago, only 4% of respondents said they had no radios at home. Continue reading

Guest Post: Control of Electromagnetic Radiation (CONELRAD)

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


Control of Electromagnetic Radiation (CONELRAD)

As recalled by Bob Colegrove

In his comment on my recent posting, Tinkering with History, Mario noted the dial on the featured radio, the General Electric P755A, sported two small triangles, one between 6 and 7, and the other between 11 and 14.  He noted that these were civil defense markers intended to show the frequencies of 640 kHz and 1240 kHz, respectively, and that these were characteristic of AM radios produce in the US roughly between 1953 and 1963.  Since two full generations have been born and raised to adulthood since that time, and I can’t find any related posting here, I thought it might be useful to bring this subject to light.

In spite of otherwise economic prosperity and general wellbeing, these years were nevertheless filled with anxiety about the prospects of all-out war.  Children of the time (myself included) were being shown how to hide under their school desks, and some of their parents were going so far as to construct air-raid shelters in their basements, and stock them with enough provisions to supposedly outlast any catastrophe.  So it was that CONELRAD came into being in 1951.  The idea was, that in case of a National emergency, all radio and TV stations would go off the air, and only certain medium wave radio stations would stay on either 640 kHz or 1240 kHz.  They would remain on for a few minutes and then other stations would take over in a round robin arrangement – this to deter homing by hostile bombers.  Needless to say, quickly changing over transmitters and antennas to one of these two frequencies did not bode well for the equipment and there were many failures in subsequent tests.  Note that, as originally conceived, the system did not provide for local weather emergencies or other situations.

The banner photo at the top of this posting shows a portion of the Hallicrafters S-38E receiver which conformed to Government law of the time required for marking all AM dials.  An S-38E just like it was my first genuine multi-band radio in 1959.  Assuming good alignment, the dots next to the CD triangles indicated the 640 kHz and 1240 kHz frequencies.  When a test came on, you didn’t have to fish for it, since CONELRAD was the only service transmitting.

Going back to the radios described in Tinkering with History, GE took this one step further.  The figure below shows a portion of the dial on a GE P806A.  Note the nub on the outer edge of the dial under the triangle at 1240 kHz.  There is another nub on the edge at 640 kHz.  Together with the raised triangular dial pointer molded on the cabinet, they provided a braille system, so that someone visually impaired could easily tune to a CONELRAD frequency.

As technology improved, CONELRAD transitioned to the Emergency Broadcast System (EBS) in 1963, and subsequently the Emergency Alert System in 1997.  A more thorough description of CONELRAD can be found on Wikipedia https://en.wikipedia.org/wiki/CONELRAD.  Reprint of an April 1955 Radio & Television News article describing the construction of a transistor CONELRAD receiver is at https://www.rfcafe.com/references/radio-news/conelrad-radio-television-news-april-1955.htm.
