Marconi Day on April 27

 


This year, International Marconi Day (IMD) is on April 27. Italian inventor and electrical engineer Guglielmo Giovanni Maria Marconi was born on April 25, 1874, and is credited for inventing the radiotelegraph system, creating Marconi's law, and sending the first wireless transmission over the open sea.

IMD was created to honor Marconi and is hosted annually by the Cornish Radio Amateur Club http://gx4crc.com/, GX4CRC. The purpose of the day is for amateur radio enthusiasts around the world to contact historic Marconi sites using communication techniques similar to those that he would have used.

The 24-hour event will operate from 0000 UTC to 2359 UTC, and registration is required. Participants can register at GX4CRC's registration web page https://gx4crc.com/imd/imd-registration/.

Stations in the United States, including Marconi Cape Cod Radio Club, KM1CC, in Massachusetts, are already registering for the event. KM1CC hosts several on-air events each year to keep the accomplishments and story of Marconi and his wireless station site in South Wellfleet alive. 

In 1975, the Wellfleet station was listed as a National Historic Landmark on the National Register of Historic Places and is now part of Cape Cod National Seashore, a unit of the National Park Service. When possible, KM1CC sets up a temporary radio station inside the park. More information about KM1CC is available on their Facebook https://www.facebook.com/KM1CC/ 

Libya, Part 3 – Mebo II & Angela

 


Special thanks to Ray Robinson and Jeff White for sharing a recent edition of Wavescan on AWR

Jeff:  The last two weeks here in Wavescan, Ray Robinson has presented the history of radio broadcasting in the North African country of Libya.  But, there’s one more aspect to broadcasting in Libya that we haven’t covered yet, that’s hinted at by the country entry for Libya in the 1978 edition of the WRTH, which lists two shortwave transmitters on the radio ship Mebo II.  There’s a bizarre story behind that entry, which deserves digging into.  So, here once again is Ray to explain what happened.

Ray: Thanks, Jeff.  Probably the most successful of the 1970’s offshore stations was Radio Northsea International, which broadcast from off the coast of Holland from early 1970 until the Dutch anti-offshore radio law went into effect on 31st August 1974.  The station operated from a ship called the ‘Mebo II’, owned by Mebo Telecommunications Ltd., based in Zurich, Switzerland.  The men behind the company were two Swiss engineers, Erwin Meister and Edwin Bollier, and using the first two letters of each of their last names, they formed the acronym ‘Mebo’.  They purchased two Norwegian ships in 1969.  The first was the Bjarkoy, which they re-registered as the Mebo, but when they realized it was too small to use as a broadcasting base, they bought a second vessel, the coaster Silvretta, which had been built in 1952.  This they re-registered as the Mebo II, and the smaller Mebo they retained as a tender for the Mebo II while it was anchored at sea.

After the station’s broadcast life in the North Sea came to an end, there was much speculation and legal wrangling as to what would happen to the ships next.  That in itself is a long story, but eventually the ships left Dutch waters on 16th January 1977.  During this period, the smaller ship, the Mebo, had been re-registered as the Angela.

The Mebo II had its original full complement of broadcast equipment on board:
two fully equipped studios,
a 100 kW RCA medium wave transmitter,
2 x 10 kW shortwave transmitters,
a 1.2 kW mono FM transmitter, and
a 140’ antenna mast.

It also had another medium wave transmitter, a 10 kW Continental Electronics unit, that had been transferred from the Radio Veronica ship, the MV Norderney.
 
The ships had Dutch captains, and crews from the Cape Verde Islands, but with them also went former Caroline and RNI transmitter engineer and DJ, Robin Adcroft (who also used the name Robin Banks on air).

Their departure was shrouded in mystery as they sailed south towards a new destination and a new role in the Mediterranean which was to be unlike anything ever experienced by an offshore radio station before or since.  On 1st February they called at Ceuta – the Spanish enclave in Morocco – to take on fresh supplies of food, fuel and water.  They then eventually arrived off the port of Tripoli on 9th February, and five days later, dropped anchor side-by-side in the harbor, 150 meters out.  The crew were all paid off, and only radio engineer Robin Adcroft remained on board.  The ships had apparently been leased to the government of Libya.

During February and March 1977, a number of non-stop music test transmissions were made by Robin from Tripoli Harbor.  These transmissions, on 1232 kHz (244m) using a power of about 40 kW, took place generally between 8 and 11pm local time (1800-2100 UTC) and consisted of records and announcements, but without any station identifications.  Later some tests were also made on 773 kHz (388m) using the old Radio Veronica 10 kW transmitter which had been installed on the Mebo II.

These test transmissions had to be halted after a few weeks because it was discovered that they were causing interference to local communications facilities in the Tripoli area.  A further widely-heard series of tests from the Mebo II began on 2nd May 1977 on 773 kHz medium wave, 6210 kHz shortwave, and 90 MHz FM.  Again the tests were presented by Robin Adcroft and consisted largely of music and announcements, but this time knowing that some European offshore radio enthusiasts would probably be listening on shortwave, the occasional RNI jingle was inserted between records.  At the top and bottom of each hour, the former RNI theme, "Man of Action" was also played.

On 19th May 1977 test transmissions also started in the 31m shortwave band on 9810 kHz, making a total of four transmitters broadcasting simultaneously from the Mebo II - the first time that had happened in over three years.

< Audio Clip – Mebo II test, Mon 23 May 1977 >

Unfortunately because of interference from the Russian Home Service on the same 31 meter band frequency, use of 9810 kHz had to be dropped in June, and the 49 meter band transmitter was switched from 6210 to 6205 kHz.

On 29th June 1977 an afternoon relay began on 773 kHz, 6205 kHz and 90 MHz of the English language programs of the Socialist People's Libyan Arab Jamahiriya Broadcasting Corporation (SPLAJBC), itself transmitting from Tripoli on 1406 kHz (214m).  These relays, heard from 1600-1740 UTC, had been arranged by Robin Adcroft on instructions from Mebo Director Edwin Bollier in Switzerland, and were thought to have been for the benefit of Libyan Embassies throughout the world.  However, no feedback was received from this potential audience and the relays ended on 16th July, although the evening music programs continued.


On 8th August both the Mebo II and the Angela raised their anchors and sailed east from Tripoli Harbor calling first at Benghazi three days later, and then on to Derna Harbor – some 600 miles from Tripoli and about as close to the Egyptian border as they could get.  Relations between Libya and Egypt had become strained and the main reason for the move was to jam Egyptian Radio’s transmissions on 773 kHz.  This was effective in the local area, but not much further afield as Egypt used 1000 kW on 773 kHz.

The Mebo II’s transmissions on 773 kHz were made using the 10 kW former Radio Veronica transmitter, and they were identified with the call sign ‘LBJ’, meaning Libyan Post-Revolution Broadcasting.  The main 100 kW transmitter on the Mebo II was ready to be used, but at the last moment the Libyan authorities, perhaps wary of escalating the tension with Egypt still further, instructed the radio engineers not to retune the transmitter or turn it on.

At this stage programs consisted of music, with no propaganda or information, and continued for about five hours each night, half of that time being live programs presented by Robin Adcroft and the remainder pre-recorded taped programs.  The Mebo II left Derna on 30th October 1977 for a new anchorage off Benghazi.

After arriving off Benghazi test transmissions were resumed on all three wavebands, but after two days engineers were instructed to turn off the medium wave and shortwave outlets, leaving only FM to carry the five hours of nightly programs. The engineers were told to keep the transmitters silent until arrangements had been made for Libyan frequencies to be allocated to them.

Despite this instruction a number of relays of the FM test transmissions were broadcast on 6205 kHz shortwave in December 1977 and early January 1978.  They were announced simply as "a program of international music on 90 MHz FM."

Interestingly, the station is listed in the 1978 WRTH, showing the frequencies of 773 kHz medium wave, 6205 and 9810 kHz shortwave, and 90 MHz FM.  Apparently at that time, it was the only FM transmitter in the country.

On 15th January 1978 the, by now regular, program didn’t start as usual at 7.00pm local time and an announcement broadcast later in the evening indicated that the Mebo II was actually sailing away from Benghazi harbor.  The radio ship eventually arrived off Tripoli once again on 19th January and broadcasts, consisting of a relay of the SPLAJBC in English, were made until 8.30pm local time.  These programs were mainly news bulletins, music, and talks about international affairs.

In February 1978, the Mebo II and the Angela both went into dry dock in Tripoli.  Some damage on the Angela was repaired, and both ships were repainted, the Mebo II in red with cream flashes, and the Angela in blue, white and black.  Whilst in dry dock both vessels were manned by between six and twelve armed guards at all times.  Coming out of dry dock, the vessels initially tied up against the quay opposite the British Embassy in Tripoli.

Broadcasts resumed on 12th March on medium wave and shortwave only, and on 27th March, the 10 kW medium wave transmitter was retuned to 1610 kHz (186 m).  Reception reports were requested to Mebo’s address in Zurich.

< Audio Clip - Mebo II test, Mon 27 Mar 1978 >

On 5th April 1978 the Mebo II and the Angela became the official property of the Libyan Government and were re-named Al Fateh and Almasira respectively.  

A foreign language service of the SPLAJBC started from Al Fateh on 11th June 1978.  Each day six Arab announcers, three French speaking and three English speaking, travelled out to the ship in Tripoli Harbor to present live programs.  The announcers relied on radio engineers Robin Adcroft and Printz Holman to operate the technical equipment for them, and they were the only two Europeans allowed on board the radio ship.  Foreign announcers hired to broadcast on the European Service of SPLAJBC were required to pre-record their programs in landbased studios.

This broadcasting arrangement lasted only until the end of the month, when plans were announced for a new daily service, consisting of readings from the Holy Koran, to be broadcast using the 10 kW medium wave transmitter on 1610 kHz, and also on 6206 kHz shortwave, between 0600 and 1800 UTC.

On 14th August 1978 Robin Adcroft and Printz Holman decided to make a clandestine broadcast on shortwave to commemorate the 11th anniversary of the British Marine Offences Act in 1967.  This transmission took place between 0500 and 0600 UTC, before the broadcasts of Holy Koran readings started, and was the last English language program made from the former ’Mebo II’.

By September 1978, all the European radio staff had left Al Fateh, and the ship was fully under the control of the Libyan technicians.  In November 1978, they adjusted the medium wave frequency from 1610 to 1611 kHz, in line with the new 9 kHz channel spacing plan.

Al Fateh was dry docked again in Valetta, Malta during June 1979, where she was once more repainted, this time in the Libyan national color, green, and with the name Al Fateh now on her bow.  She returned to Libya in the first week of September 1979, and recommenced transmissions of SPLAJBC shortly afterwards.  Shortwave programming was logged on 7165 kHz in the 41 meter band, with the 1980 WRTH listing transmissions on 1611 and 7165 kHz.

Al Fateh continued to be used to relay Holy Koran readings from the SPLAJBC until mid-1980, with the last logging by international radio monitors being on July 20th (1980).  The ships were expensive to maintain, and with new transmitting stations then available on land, the ships were no longer needed.  Robin Adcroft said he went back to Libya in the second half of 1980 to supervise the de-commissioning of equipment from Al Fateh in Tripoli harbor.  It was put in storage with the intention of later installation on land, although it is believed that never happened.  Finally, both ships were unceremoniously towed into the Mediterranean and sunk as the result of being used as target practice by the Libyan Air Force.

Back to you, Jeff.

Shortwave Radiogram, Program 350


Hello friends,

An active sun has resulted in some recent disruptions to shortwave propagation. Generally Shortwave Radiogram has been lucky in sidestepping these events, so let's hope this pattern holds up. And while solar activity can cause brief dropouts on shortwave, in the longer term the ionosphere is fortified.

From space weather to terrestrial weather, here in northern Virginia we recently experienced the proverbial quarter-sized hail. The thuds on our roof were very noticeable. But it all melted quickly, given that the temperature was 80F/27C. An image of our area hailstones will be transmitted on this week's show.

A video of last week's Shortwave Radiogram (program 349) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 350, 18-24 April 2024, in MFSK modes as noted:

Libya, Part 2 – MW & SW

 


Special thanks Ray Robinson and jeff White for sharing a recent edition of Wavescan on AWR

Jeff: Last week here in Wavescan, we presented the first part of our profile of radio broadcasting in the North African country of Libya, which covered the early Morse Code wireless stations, and also the program broadcasting stations that were established after the Second World War by the British and American Forces.  Today, Ray Robinson presents part 2 in the story of radio broadcasting in Libya; looking now at the government radio services, on both medium wave and shortwave.

Ray: Thanks, Jeff.  Actually, radio broadcasting on the part of the Libyan government was quite late getting started, as compared to similar events in other countries.  As far as we can determine, the first government-operated radio broadcasting station in Libya was on the air for a brief period of time in Cyrenaica in 1947.  One isolated monitoring report informs us that the station was operating in the 19 metre shortwave band on 15320 kHz. 

It appears this station was primarily a communication station located in the eastern city of Benghazi, but that it was also on the air temporarily with program broadcasting.  From what we can glean from listings in the early editions of the WRTH, the first permanent broadcasting station in Libya was installed in the capital city, Tripoli, probably in 1953.  It was quite a small facility, operating with just 250 watts on 1552 kHz.  This was likely an interim facility while a larger station was under construction.  That larger medium wave station was inaugurated five years later, with 50 kW on 1052 kHz, in the outskirts of suburban Tripoli.  Around the same time, a shortwave transmitter was installed at El Beida, the most northerly point in eastern Libya, and this was listed with 3 kW on 6140 kHz. 

Over the years, at least two additional shortwave transmitters rated at 100 kW were installed at El Beida, and also a 500 kW medium wave unit for wide area night-time coverage in Africa, as well as nearby Mediterranean areas.  The shortwave usage at El Beida was closed out around the year 2000.  Work commenced at another shortwave station listed as Benghazi in 1958.  Over the years, several transmitters were installed at this location, including 3 kW, 7½ kW, 10 kW and at least one at 100 kW. 

In 1998, Muammar Gaddafi declared that Africans and not Arabs are Libya's real supporters.  The Libyan state-owned radio 'Voice of the Arab World' was then renamed 'Voice of Africa'.

These days, no shortwave unit is active at the Benghazi location, and the last 100 kW medium wave unit there, that had been operating on 675 kHz, went silent in 2018.  

In the early 1970’s, work commenced on the construction of another shortwave station located at Sabratha in the northwest corner of Libya.  At the time, it was stated that this would become the largest shortwave station in all of Africa, with four Thomson transmitters rated at 500 kW each and a total of 48 curtain antennas.  For many years, test transmissions were noted from this supposedly large station, and ultimately, in 2002, program broadcasting began under the title, “Voice of Africa”. 

It seems that the Libyan authorities would often prefer to build a new radio station instead of maintaining and repairing an existing one.  Another shortwave station was constructed at Al Assah, again in northwest Libya, near the border with Tunisia. This facility was first inaugurated on August 28, 1996; and then it was re-inaugurated on December 8, 2001 with four shortwave transmitters.  This station is no longer listed as active on shortwave, and neither is a 500 kW medium wave unit there which used to be on 1449 kHz.

As if they didn’t have enough transmitter locations, at least two more are known to have been constructed, both at inland oasis locations.  One was at Sebha in the middle of the country, with two 100 kW Harris transmitters; and the other at Ghat in the bottom south west corner of the country, also with two 100 kW transmitters.  The Sebha station was used to broadcast radio programming from 1985 to 2002; and the Ghat station was heard in Bulgaria with test transmissions in 2007, although apparently it was never taken into full time broadcast usage.  To make things more complicated in the radio scene in Libya, the Transmitter Documentation Project, published by Ludo Maes in Belgium, lists a total of two dozen additional shortwave transmitters that were installed at unknown locations in Libya from the mid-1970’s to around 2005. 

No doubt many of these units were installed at already existing locations, but perhaps new locations were also involved.  These additional units were procured from Siemens-RIZ in Zagreb, Croatia.  It would appear also, that various transmitters at various locations in Libya were used for varying time periods for general government communications, in addition to program broadcasting.

We should also mention that Libya took out a relay from four shortwave transmitters at 500 kW located at Issoudun in France, beginning in 2003.  
Programming from Libya to France was provided by at least one communication transmitter, located at either Sabratha or Sebha.  This program service was presented under the same title, “Voice of Africa”, and it was on the air for a period of some five years.

So, what can you hear from Libya these days?  In short, nothing.  The shortwave transmitters are long gone, and the high-powered medium wave transmitters were progressively closed down, with the last two, in Tripoli and Benghazi, being listed as active for the final time in the 2018 edition of the WRTH.

All radio broadcasting in Libya now is on FM only, although since the end of the civil war a few years ago, privately owned stations are now allowed, and there is even a Voice of America Africa station along the coast east of Tripoli at Misratah with 1 kW on 91.1 FM, and BBC Arabic stations in Benghazi, Tripoli and two other locations, all on 91.5 FM, again with 1 kW.

In what might be described as better times, Libya issued large colorful oversized QSL cards for their broadcasts on both medium wave and shortwave.  These cards identified the shortwave broadcasting service from Libya as “Radio Jamahiriya”, and they were obtainable from two different addresses, one in Libya and the other in Malta.  The QSL card, printed in English and Arabic, depicted a large ornate rainbow. Other QSL cards from Libya showed current rural scenes and ancient historic scenes throughout the country.

Next week, I plan to bring you the strange story of the relocation of the offshore radio ship Mebo II from The Netherlands to Libya, its broadcasting history there, and its ultimate demise in the Mediterranean after being used for target practice by the Libyan Air Force.

Back to you, Jeff.

Libya, Part 1 – BFBS & AFRTS

 


Special thanks to Ray Robinson and Jeff  White for sharing a recent edition of Wavescan on AWR

Jeff: 13 years ago in 2011, one country that was very much in the news amid political turmoil and vicious fighting was the Arab Islamic State of Libya.  80 years ago, the same area featured prominently in the see-saw battles fought by the European powers during their North Africa campaigns.  This week, Ray Robinson begins a three-part series on the history of radio broadcasting in Libya, starting with the earliest wireless stations, and some radio broadcast stations that were operated by British and American personnel from shortly after the Second World War, up until 1970.  Here’s Ray.

Ray:  Thanks, Jeff.  The country of Libya is located in North Africa, approximately in the middle of the Mediterranean coastline.  Libya is about 1,000 miles north/south and also 1,000 miles east/west, although with an irregular shape.

Almost the entire country is covered by the Sahara Desert, with a 50 mile strip of arable land along the coast, and a few oases inland.  The hottest temperature ever recorded on Earth occurred in Libya on September 13, 1922, when the temperature was measured at 136 degrees Fahrenheit, 58 Celsius.

The current population of Libya is around 7.2 million and the capital city is Tripoli, although the largest city is Benghazi.  Oil was discovered in quantity in 1959, and these days the sale of oil forms 80% of the national economy.

This area of North Africa was inhabited by Berber tribespeople in earliest ancient times, and Phoenicians from the Palestine coast settled in the area around 700 BC. One hundred years later, the Greeks colonized the area, followed by the Romans, who in turn were followed by the Vandals from central Europe, and then the Arabs came in around the 600’s AD.  In 1912, Italy took over Libya, and after World War 2, Libya formally gained independence in 1951.

For those who have an interest in Biblical backgrounds, the original Berber tribespeople are descended from Noah’s son Ham; and Libya is mentioned by name in the Bible more than a dozen times.  The early Christian church remembered that a man by the name of Simon, from Cyrene in north eastern Libya, was arrested by Roman soldiers and was forced to carry the cross along the via Dolorosa in Jerusalem on behalf of the Messiah.

Wireless communication came quite early to Libya, and the first stations were installed immediately after the end of World War 1.  These early wireless stations were located in Tripoli as ICK; in Benghazi as ICJ; and Tobruk as ICU; together with four other regional locations.

However, radio broadcasting came quite late to Libya, and interestingly, the first medium wave stations weren’t installed until after the Second World War, and were operated by British & American forces personnel, not by the national government or commercial interests.  According to all available references, there was a total of six different BFBS stations on the air in Libya giving coverage to four different localities on AM, FM & SW; and just one AFRTS station on AM medium wave.

We look first at the British stations. According to Doreen Taylor in her book, “A Microphone & A Frequency”, the first two British stations were erected somewhat simultaneously during the year 1946, in Benghazi & Tripoli.  Both stations were quite small to begin with, using whatever electronic equipment was available.

The original station in Benghazi was located on what had been the Italian airfield, and quite soon, in 1947, an attempt was made to broadcast on shortwave.  The transmitter was an American-made RCA unit rated at 7½ kW, and the chosen channel was announced as 11820 kHz, though monitoring observations in Australia stated that the channel was more like 11850 kHz.  Unfortunately, these BFBS shortwave broadcasts caused interference to a regular BBC transmission, so the first attempt at shortwave broadcasting was aborted.

However, shortwave broadcasting was again attempted on two subsequent occasions; in 1949 on 4780 kHz, and in 1956 with 7½ kW on 4930 and 7220 kHz.

Two years after the station was inaugurated, Arabic programming was introduced for the benefit of local citizens.  Four years after that, the station was flooded following heavy rains in the hills nearby.  However, due to quick action on the part of the station personnel, very little damage was done to the station equipment.

The Benghazi station was closed in February 1958, but upon the insistence of King Idris, a smaller station was reopened in 1960 with 1 kW on 833 kHz, installed in an empty ward in what had been the base hospital in Wavell Barracks.  Later in the 60’s, a 4 kW FM transmitter was added on 97.8 MHz.  But, when most of the British forces left the area, the station was taken over temporarily by Signals personnel, and soon afterwards it was closed.  The last listing for the station in the WRTH is in 1968.

The BFBS station in Tripoli likewise had a double life.  It was located initially in the British army barracks at Mareth, and ten years later the station was transferred to Miani Barracks four miles away.  Likewise, shortwave coverage was tried from this station, and it was noted in England on 4785 kHz in 1953.  This station, with 1 kW on 1394 kHz, was finally closed in January 1966.

A third BFBS station located at Tobruk came on the radio scene considerably later than the previous two.  It was inaugurated in July 1964, and radiated 1 kW on two channels, 1439 & 1484 kHz (208 and 202 meters), as well as on 89 MHz FM.

Interestingly, the programming from the Tobruk BFBS station was also relayed over an FM transmitter on 90.2 MHz at El Adem, 17 miles inland, which received its program feed via a landline connection.  The Tobruk station was closed after six years of service in 1970.

BFBS in Libya was therefore on the air on shortwave from two different locations, Benghazi in 1947, 1949 & 1956; and from Tripoli in 1953.  And yes, these BFBS stations in Libya did issue QSL cards, though these days they are quite rare.  Dr. Adrian Peterson’s Heritage Collection does contain one such card, verifying BFBS Benghazi on shortwave with 4 kW on 3305 kHz in 1954.

From 1943 to 1970, the United States Air Force operated the Wheelus Air Base on the coast near Tripoli, a facility that had originally been constructed by the Italian Royal Air Force in 1923.  On the base there was an American AFRTS station, both radio and TV, and it appears from listings in the WRTH that the radio station was first launched in 1954 with 100 watts on 1510 kHz.  The TV station was added early in 1955.  Very little is known about either station; they must have had American callsigns, but what they were, we don’t know.  When they were closed in 1970, the radio station was operating with 1 kW on 1594 kHz.

The significance of the closure in 1970 of both BFBS Tobruk and AFRTS Tripoli is that it was on September 1st, 1969 that King Idris I was overthrown by Muammar Gaddafi in a successful military coup d’état.  Before the revolution, the US and Libya had already reached agreement on US withdrawal from Wheelus.  This proceeded according to plan, and the facility was turned over to the new Libyan authorities on 11th  June 1970.

Next week, we’ll take a look at the domestic governmental radio operations in Libya, on both medium wave and short ave.

Back to you, Jeff.

The Zenith Radio Story - Part 1

 

Jeff: Recently, Wavescan listener Vince Koepke sent us a pdf copy of a brochure produced by the Zenith Radio Corporation in 1955, detailing some of the early history of the company.  If you’ve ever been lucky enough to own a Zenith Trans-Oceanic receiver, you’ll know how important this company was to the shortwave listening audience.  The brochure makes for fascinating reading, and so we’ve decided to serialize it over a few weeks here in the broadcast.  This week, Ray Robinson has the first part, covering from the very early days up until the early 1920’s.

Ray:  Thanks, Jeff.  The history of Zenith was to a considerable degree a history of the radio-television industry in the United States.  This was so because Zenith was a pioneer and leader in radionics since before there was a radio industry, and it played an important role in almost every important development during radio growth from an amateur toy to the most significant, widespread, and effective system of communications in history.

On December 14, 1901, Guglielmo Marconi flashed the letter “S” across the Atlantic Ocean by wireless telegraph, and thereby launched a revolution in communications that was destined to bring profound changes in the pattern of civilization. Marconi’s tremendous achievement brought only passing attention from the adult public, but it kindled the imagination of eager youngsters everywhere.  In the decade that followed, many of these youngsters dismayed their parents by devoting more time and effort to “Marconi’s toy” than to preparing themselves for a future in “something practical”.

Beginnings 
Two of these “wireless doodlers” lived hundreds of miles apart, and were to meet only by sheer chance.  R.H.G. Mathews of Chicago pursued the hobby and qualified as an amateur radio operator in 1912.  In 1915 he began building and selling wireless equipment to other amateurs.  Karl Hassel of Sharpsville, PA, won his amateur license in 1915, and then matriculated at the University of Pittsburgh.  Here he discovered that he was the only person on the campus, student or faculty, who knew how to operate the University’s newly constructed wireless station.

Came World War I, and both boys enlisted in the Navy.  They met at Great Lakes Naval Training Station, and worked together on radio until 1918.  They then set up a continuation of Mathews’ business as Chicago Radio Laboratory, building and selling radio sets.

Their first factory was a table in Mathews’ kitchen.  Their tools were pliers, screwdrivers, a hand drill, and a soldering iron that had to be heated over the burner of a gas stove.  From this kitchen table workshop grew the business that was to become Zenith Radio Corporation.

Early in their business life Mathews and Hassel began a long series of radio “firsts” that became a Zenith tradition.  One of their first ventures was construction of a longwave radio receiver for the Chicago Tribune, which was used to pick up news dispatches about the Versailles Peace Conference from a longwave station in France.  This short circuiting of the congested trans-Atlantic cable enabled the Tribune to beat competitors by 12 to 24 hours on conference stories.

The varnish had scarcely dried on the kitchen table workbench before the fledgling business needed larger quarters.  The boys built a new factory near the Edgewater Beach Hotel.  It was a shanty-like structure that gave them a working space of 14 by 18 feet, with a cubby hole for their amateur radio station, 9ZN.  At about the same time they published their first catalogue.  A few months later they coined the trade name, Z-Nith, from the call letters of their radio station.  This was the origin of the trade mark, Zenith.

The next Z-Nith first was construction and installation of a wireless system that made the Nashville, Chattanooga & St. Louis Railway the first railroad in the world to successfully dispatch trains by wireless telegraph.  Transmitters and receivers were set up in Tullahoma, TN and Guntersville, AL to handle traffic over the rough country between.

Initial difficulties included such things as the transmitters setting off a bank’s burglar alarm during a directors’ meeting; adding a high voltage shock to the pain of a dentist’s drill while he was working on a touchy patient; and putting nearby telephones out of service.  These problems were ironed out.  The system went into service, and operated successfully for several years.

By the end of 1919, the Z-Nith partnership was thriving, with production exceeding one complete set per week.  In May, 1920, the boys acquired their most important asset, a license to use the basic regenerative circuit patent of radio’s greatest inventive genius, the late Major Edwin H.  Armstrong.

Until the latter part of 1920, Chicago Radio Laboratory concentrated on building equipment for the growing army of radio amateurs, or “hams” as they soon came to be known.  A change came in November of that year.  Radio broadcasting as we know it today was non-existent.  The University of Wisconsin had begun in 1919 a regular broadcast schedule of news, market reports, weather information, and general programs from its station 9XN (now WHA, which has been licensed to the University of Wisconsin since 1922 and still broadcasts Wisconsin Public Radio 102 years later on 970 AM).

Initially as a public service for radio amateurs, WHA developed a unique program.  Each noon it radio-telegraphed the weather report in fast code for expert “hams”.  The report was then repeated in slow code so that beginners could take it.  After that, an announcer read the weather report for the general public, and so that beginner “hams” could check their accuracy.

Here and there around the country other stations produced similar schedules, but only a narrow segment of the public showed interest.

Then came the presidential election of 1920.  News of the Harding landslide was disseminated with startling speed throughout the country by station KDKA in Pitts- burgh and other stations.  The public suddenly realized that Marconi's toy was a very useful and practical communications tool.  Broadcasting began in earnest.
Hassel and Mathews quickly put on the market a receiver with which the general public could hear the growing number of broadcasts.  Business boomed, and within a few months the walls of Chicago Radio Laboratory's new factory were bulging.  So the company moved to a mammoth 3,000 square foot plant on Ravenswood Avenue, with a staggering rental of $300 per month, and a payroll of six employees.  At this time the boys bought their first power tool, a motor-driven drill press, and boosted production to more than one set per day.

McDonald Joins the Partnership 
In the meantime, E.F. McDonald, Jr., of Syracuse, NY, had established himself in the automobile business in Chicago, where he introduced the first successful plan for selling automobiles on time payments.  He had served through the war in Naval Intelligence and been discharged with the rank of Lieutenant-Commander; and was looking around for a new business.

On New Year’s Eve, 1920, McDonald went to a garage to pick up his automobile, and noticed several men listening to music coming from a box.  He asked the proprietor what there was about this phonograph to make people listen to it on New Year’s Eve.

“That is no phonograph,” he was told.  “That is a radio.  They are listening to music through the air from Pittsburgh.”

McDonald learned that it would take several months to get delivery on a radio set for himself, and decided he had found his new business for which he had been searching since the end of the war.  However, it was not that simple.  He found out that he would need a license to use the inventions of Major E.  H.  Armstrong, and Armstrong licenses were no longer available.

Temporarily balked, McDonald soon heard about two young men — Hassel and Mathews — who were building radio receivers on Chicago’s north side.

Thinking about that radio set, he paid a visit to the Ravenswood factory and took particular fancy to a set that sold for $75.00, less tubes, batteries, and headphones.  Hassel, in person, came to McDonald’s residence at the Illinois Athletic Club to install it—and didn't leave until he had collected his money.  Recalling the occasion, Hassel said, “It wasn’t a question of whether I trusted him or not—we needed the money to keep going.”

Hassel and Mathews had the all-important Armstrong license, and more business than they could handle with the equipment they owned.  But they were short on capital.  McDonald joined forces with them, provided funds for expansion, and became general manager of Chicago Radio Laboratory.  One of his first moves was to change the trade mark from Z-Nith to Zenith.

Normally, capital investment in an existing business results in an equity for the investor.  In this case, however, the largest investor, McDonald, owned no interest whatsoever in Chicago Radio Laboratory, and for a very good reason.  The Armstrong license was held by Chicago Radio Laboratory, a co-partnership, and was not transferable.  This also had its bearing on the organization of Zenith Radio Corporation.  When that company was formed in 1923 it was not a manufacturer.  Instead, it was the exclusive sales and marketing organization for handling the radio equipment built by Chicago Radio Laboratory.  This arrangement continued until other developments made a consolidation possible, at which time the entire assets and business of Chicago Radio Laboratory were acquired and Zenith became a manufacturer in its own name.

And that’s where we have to leave the Zenith story this week.  We’ll continue with Part 2 in a few weeks’ time.  Back to you, Jeff.

Update on Myanmar's Thazin Radio

 

Myanmar - Thazin Radio has been silent on shortwave since April 7, 2024.

It seems shortwave transmitter Pyin Oo Lwin is having a bit of trouble. However, I caught them tuning in on 639 kHz just now, at 13:00 UTC, mingling with a Thai station. Thazin Radio is part of the Myawaddy Communication Center and is owned by the military in Myanmar. It's financed by Myanmar Economic Holdings Limited (MEHL), which is a conglomerate owned by the military.
(Sarath Weerakoon 4S5SL, Mt.Lavinia beach, Sri Lanka,

Myanmar - Thazin Radio from Pyin Oo Lwin site on 7345 kHz.

12.40 past 13.15 UT in vernacular. Lots of popular songs. Am I the only listener noticed improved signals from Thazin Radio. Has this station operated by Tatmadaw, upgraded its tramsmitter out put and the antenna system?
(Sarath Werakoon-Mt. Lavinia-CLN  4S5SL, via wwdxc BC-DX TopNews April 2)

Pyin Oo Lwin of Myawaddy Radio center built in 2007 to 2008 years, some 208 far away kilometers north of new capital Nay Pyi Daw. Location is at  22 00 57.41 N  96 33 00.48 E or 22.01741925751829 N  96.55174262265729 E  northerly point in Myanmar.

Thazin Radio from Pyin Oo Lwin. I don't know the reason why Japanese Aoki Nagoya group circle recently put the 208 kilometers distant location - capital name - Nay Pyi Daw on their SW frequency database - for a year now, i.e. 6165, 7345, and 9590 kHz requested channels ?
