Compact Antenna, Big Results: Giuseppe’s DICA 2 Redesign

Many thanks to SWLing Post contributor Giuseppe Morlè, who writes:

Dear Thomas and Friends of the SWLing Post,

I am Giuseppe Morlè, IZ0GZW, writing to you from Formia, in central Italy, on the Tyrrhenian Sea.

Do you remember the DICA 2 antenna? It was a small, shortened antenna with three ferrite cores inside, capable of tuning across all shortwave bands. Unfortunately, it no longer exists in its original form.

I have completely reworked the windings to enable the ferrites to also function for medium wave (MW) reception. Now, the antenna features:
• 35 turns for medium waves,
• 4 turns for shortwaves, and
• the same variable capacitor of over 1000 pF remains in use.

For medium waves, the antenna works wonderfully by induction. You simply place the ferrite core near the tube and turn the variable capacitor to achieve perfect tuning across the entire MW range.

I was genuinely amazed by its performance on shortwaves. Despite its small size, the antenna provides excellent gain, especially when a ground cable is connected to the variable capacitor’s casing.

I conducted several tests on my balcony. Initially, I thought the random ground wire simply improved the rotor’s tuning capability, but I discovered the antenna works equally well even when placed on a metal surface.

During a recent outing to Monte Orlando Park in Gaeta, I observed how the ground cable significantly enhanced both the signal strength and audio modulation. You can see this in my latest video, where I received Australian operators Greg and Grant on 20 meters with excellent signals.

The antenna’s two windings are separated and connected to the stator and rotor of the variable capacitor. On one end of the shortwave winding (the 4 turns), I’ve added a crocodile clip that can be attached or detached to switch between shortwave and medium wave operation. All of this functionality is achieved with a single variable capacitor.

I will soon share videos demonstrating all of these details and performances.

Thank you, Thomas, for your incredible activations—I follow them regularly on your channel, and they are a constant source of inspiration for me.

Greetings to you and all the Friends of SWLing Post!

73,

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

XHDATA D-808 Radio

XHDATA D-808: Another User’s Review (and discount codes)

 

By Robert Gulley

I admit to being hesitant to review this radio when XHDATA contacted me, as our own armchair portable radio guru, Jock, had written an excellent review of the radio back in June of this year, and because the radio has been out for some time (6 or 7 years, I believe). After a time, I decided my take on the radio, like any other, would be just another facet in considering its place in the radio world at large, or possibly on your radio shelf, and hence this review.

Lightweight and a Sturdy Antenna

As Jock mentioned in relation to other lightweight DX machines, this radio is indeed light, yet sturdy, and very easily portable. Unlike many small radios, care has been taken to make the antenna solid and tall. This means it can pull in a lot of signals safely (unless, like me, you are comparing it side-by-side with three other radios and find yourself having antenna sword fights as you move radios around, but I digress. Fortunately, nothing bad happened to any of the radios!). When sitting on a table, the built-in stand is stable, and allows pressing buttons solidly with one hand – the radio does not slide around or threaten to be knocked over in the process. That might seem like a minor thing, but many stands are less than reliable in this regard.

Operating the Radio

While I would prefer a slightly larger offset to the buttons from the surface of the radio, this did not cause much of an issue whether hand-held or on its stand. There were a few times when I thought I had pressed a button sufficiently but no response, but a second, harder press worked, so I just needed to take that into account when tuning in frequencies using the keypad, or when changing modes, etc.

The radio has a number of functions, clearly labeled, including operations performed when the radio is off, labeled in orange. Other orange labels indicate secondary or sub functions when the radio is on, such as the “Meter” function which, when in SW mode, cycles through the shortwave bands.

A small but useful feature I really appreciate related to this is the meter identification displayed along with the frequency as you cycle through the shortwave bands. For some reason I have a hard time remembering which set of frequencies is represented by which SW meter band. Perhaps with this radio I can finally get them firmly entrenched into my old brain!

Fine Tune Dial

The Fine Tune dial works especially well with a broad range of adjustment depending on the mode.

Another operating feature that I found very useful is the Fine Tuning dial on the side of the radio. This works as one would expect in Shortwave and SSB mode, allowing for slight adjustments to bring in a voice or CW signal in the amateur bands, but also allows one to off-tune from the standard receive frequency when a signal is being interfered with or picking up static etc.

This is nothing particularly new, but what is impressive to me is that it works for MW signals as well. Being able to go from 700 kHz to 701 or 702 kHz, for example, sometimes allows for a more intelligible signal, particularly at night when there can be multiple stations coming in on the same frequency.

On more than one occasion this was useful, especially since this means one does not have to change the tuning rate to make an adjustment. Your main tuning stays at the 9 or 10k you have set, and when you move the main tuning dial, it jumps to the next proper frequency. In this example, 701kHz becomes 800kHz with the next turn of the main tuning dial or up arrow,

Listening

The audio is good for its size due to the large speaker, and the multitude of filter options in the radio for every mode (except FM) allow you to tailor the audio to what you prefer, or what will allow you to mostly, or totally, eliminate interference from strong nearby stations. For those who like to listen to amateur radio bands, the filter capability is even more useful, particularly since it goes down to 500 Hz, great for listening to Morse code!

The number of filters is amazing given the price point of this radio, and it begs the question, if XHDATA can do this, why can’t other companies do this too? This is a big selling point for the radio in my book.

As I mentioned earlier, I compared three other radios to the D-808, a Sony 7600GR, a Sangean 909X2, and a C.Crane Skywave. The results were both predictable and surprising. Predictable in that the Sangean with the larger speaker had better audio, the Sony with SSB sync that actually works (unlike many models that try and fail!) was a bit clearer most of the time on SSB, and the Skywave was weaker in strength due partly, at least, to the smaller antenna, and lesser audio due to the smaller speaker.

What was unpredictable was when the D-808 pulled in stations better than the Sangean or Sony – not often, but some times. Similarly, the D-808 would sometimes hear two MW broadcast stations when the other three would only hear one. All three were used at times with a Tecsun AM loop antenna to boost MW signals, as well as with their bare ferrite antennas. Most of the time the MW signals were pretty even, but sometimes the D-808 won out.

While I have yet to own the perfect radio, and I have owned a lot of radios, this radio does what it promises, and does it well. As I note below, there are pros and cons and quirks to every radio, and what may be a quirk or a con to me may not be to others.

 

PROs, CONs, and Quirks

PROs

  1. Excellent sensitivity on FM (good telescopic antenna) and AM (internal ferrite antenna excellent given the size of the radio)
  2. Includes the AIR band, SSB with USB and LSB, and LW
  3. 6 filters for SW, 7 for MW/LW, and 6 for Air (WOW!)
  4. Fine Tuning Dial works in all modes to help reception
  5. Tuning Dial can be adjusted for Fast or Slow tuning steps, and can be set to STOP to lock in a station so that if the dial is accidently nudged, the station will not get changed.
  6. Direct Keypad entry of frequencies
  7. Feature rich for an (almost) ultralight radio
  8. External antenna jack
  9. Long-lasting battery
  10. Reset Button to go back to square one if needed

CONs

  1. While I do not mind soft muting, this radio does make a “chuffing” sound in certain modes when tuning manually (but not when finding stations with ATS). That’s not a deal-breaker for me, but it will be to some, I know. This is likely due to the AGC “attacking” the audio as it returns from the soft muting.
  2. Minor Nit: While the battery life is good with the rechargeable battery included, I always prefer AA-sized batteries for their almost universal availability.
  3. Memory access is limited, not by the number of memories, but by an easy way to tune through them. Memory Pages should link seamlessly for scanning purposes, but this is not an uncommon CON with many other radios.

Quirks

  1. Setting the Sleep Timer to “On” actually turns it off. Really.
  2. Sometimes if the Clock adjustment is set to Auto, an FM radio station that broadcasts RDS time and date info might reset the time to something different, such as when hearing a station from a different time zone. I prefer to set the clock manually to my local time (or more likely, to UTC time) just to keep it consistent, and that option is available for this radio.
  3. I have noticed when another radio is near, when changing the frequency manually, in addition to the chuffing noise of the D-808, the other radio will make a popping sound with each change. This is not likely to be an issue in normal operation, but if comparing two radios, or listening to two different radios at the same time, you will likely hear it.
  4. The alarm time set shows on the main display when the radio is turned off, regardless of whether the alarm is set to go off or not. This was very confusing to me at first, as I expected the display to go off when the alarm was not set to go off.

Wrap-up

This is a neat little radio that, as they say, punches above its weight class. It can fit in a jacket pocket easily, it’s lightweight, it has features which not many other portables have, or have as fully, and the audio is quite good for its size.

This is indeed an armchair receiver, but with the addition of a MW loop antenna, or a longwire plugged in for shortwave/amateur or LW/MW bands, there are many more opportunities for bagging distant stations.

There are enough features to make it quite usable for travelling, but not so many bells and whistles that operation becomes cumbersome. And with keypad entry for when you want immediate gratification, there’s no long minutes or hours of tuning manually to get to the frequencies you want.

I believe the radio comes in at a good price point, ticks most boxes a user would want for a radio in this class, and has a track record of good reliability after a number of years on the market.
